Öğe Energy Analysis in Green Building via Machine Learning: A Case Study in a Hospital(MDPI, MDPI AG, Grosspeteranlage 5, CH-4052 BASEL, SWITZERLAND, 2025) Tombal, Nevzat Yağız; Mumcu, Tarık VeliElectricity consumption is increasing as a result of increasing people’s needs, such as lighting, heating, and comfort. Different needs come into play day by day in the houses where people live and in places used as common areas, and this increases the need for electricity. Studies have observed that almost half of the world’s electricity consumption is made by buildings. Public buildings, shopping malls, hospitals, and hotels are typical examples of such structures. However, hospitals have an important place among all building types as they contain a wide range of devices and are of critical importance to many systems. Consumption in hospitals is a necessity rather than a desire for comfort in places such as hotels and shopping malls. Therefore, analysis of the energy consumed by hospitals is one of the important things to perform to reduce the damage caused by electricity consumption to the environment. In this study, the energy analysis of a green hospital with an installed area of 55,000 square meters in Istanbul was conducted, and machine learning techniques can be used in the analysis. Among many methods used for building energy analysis, long short-term memory (LSTM) has been chosen. The available data set was analyzed with the various LSTM methods and classification and prediction operations were carried out. Error rates for each method were compared. With the results obtained, it has been observed that the vanilla LSTM method provides acceptable results in building energy analysis.Öğe Effect of Different Heat Sink Designs on Thermoelectric Generator System Performance in a Turbocharged Tractor(MDPI, MDPI AG, Grosspeteranlage 5, CH-4052 BASEL, SWITZERLAND, 2025) Gürcan, Ali; Yakar, GülayIn this study, the effects of different heat sink designs on the cold side of the modules in a thermoelectric generator (TEG) system placed between the compressor and the intercooler of a turbocharged tractor on the system performance were numerically analyzed. In the current literature, heat sinks used in TEG modules generally consist of plate fins. In this study, by using perforated and slotted fins, the thermal boundary layer behaviors were changed and there was an attempt to increase the heat transfer from the cold surface compared to plate fins. Thus, the performance of the TEG system was also increased. When looking at the literature, it is seen that there are studies which aim to increase the performance of TEG modules by changing the dimensions of p and n type semiconductors. However, there is no study aiming to increase the performance of TEG modules by making changes on the plate fins of the heat sinks used in these modules and thus increasing the heat transfer amount. In this respect, this study offers important results for the literature. According to the numerical analysis results, the total TEG output power, output voltage, and thermal efficiency obtained for S0.5H15 were 6.2%, about 3%, and about 5% higher than those for PF, respectively. In addition, the pressure drop values obtained for different heat sinks, except for aluminum foam, were approximately close to each other. In cases with TEG systems where different heat sinks were used, the intercooler inlet air temperatures decreased by approximately 3.4–3.5% compared to the case without the TEG system. This indicates that the use of TEG will positively affect the improvement in engine efficiency.Öğe Antioxidant, and enzyme inhibition effects of chia (Salvia hispanica) seed oil: A comprehensive phytochemical screening using LC-HR/MS(PONTIFICIA UNIV CATOLICA VALPARAISO, AV BRASIL 2950, PO BOX 4059, VALPARAISO 0000, CHILE, 2025) Mutlu, Muzaffer; Bingöl, Zeynebe; Özden, Eda Mehtap; Köksal, Ekrem; Ertürk, Adem; Gören, Ahmet C.; Alwasel, Saleh; Gülçin, İlhamiBackground: In this study, the antioxidant and anti-Alzheimer’s disease properties of Chia (Salvia hispanica) seed oil (CSO) were determined for the first time. Three different metal reduction and two different radical scavenging methods were used to determine the antioxidant properties of CSO. It exhibited higher antioxidant activity than vitamins E and C in the CUPRAC method. Results: CSO has shown excellent efficacy in the antioxidant methods used in this study. In the DPPH radical scavenging method, CSO exhibited higher radical scavenging potential than BHT, a standard and synthetic antioxidant. The anti-Alzheimer’s disease properties of CSO were determined by inhibition of acetylcholinesterase enzyme and its IC50 value (17.60 lg/mL) was found to be close to the IC50 value of tacrine (8.82 lg/mL), the standard inhibitor of the enzyme. Inhibition properties of a-glycosidase enzyme and human carbonic anhydrase II isoenzymes were also studied. It was understood that CSO inhibited both enzymes at a lower rate than standard inhibitors. Also, the total phenolic and flavonoid contents of CSO were determined as 784.44 lg gallic acid equivalent (GAE)/mL oil and quercetin 150.00 lg QE)/mL oil, respectively. In addition, LC-HRMS chromatography application was performed to understand the phenolic content of CSO. It was determined that isosakuranetin (29.07 mg/L oil) was the most abundant polyphenolic compound in CSA. Also, seven polyphenolics of the studied remained below the detectable amount. Conclusions: It was found that CSO had effective antioxidant activity, polyphenolic contents and potent enzyme inhibition properties, associated with some global disease.Öğe Performance of water systems during the February 6th Kahramanmaras earthquakes(SAGE PUBLICATIONS INC, 2455 TELLER RD, THOUSAND OAKS, CA 91320, 2025) Toprak, Selçuk; Wham, Brad Parker; Naçaroğlu, Engin; Ceylan, Muhammet; Dal, OğuzFebruary 6th, 2023 Mw7.7 and Mw7.6 Kahramanmaras earthquakes caused severe damage to lifeline systems across 13 provinces in Turkiye and regions of Northern Syria. Impacts to water and wastewater infrastructure were significant, requiring the mobilization of support from across the region, and around the world to provide life-sustaining service to the approximately 14 million impacted people. This study documents water infrastructure performance during the event and efforts required to repair damage during the days and months that followed. With a particular focus on water transmission and distribution pipelines, details acquired during multiple field reconnaissance visits and meetings with officials are provided for the most heavily impacted water utilities. Both general recovery efforts and specific examples of earthquake-induced pipeline damage are incorporated to draw conclusions relative to emergency preparedness, resilient network design, and communication across agencies as well as with the public.Öğe Advancing sustainable food preservation: Ultrasound and thermosonication as novel approaches to enhance nutritional and bioactive properties of broccoli juice(Elsevier Ltd, 2025) Yıkmış, Seydi; Türkol, Melikenur; Dülger Altıner, Dilek; Duman Altan, Aylin; Sağlam, Kübra; Abdi, Gholamreza; Tokatlı, Nazlı; Çelik, Güler; Aadil, Rana MuhammadTo meet the challenges of sustainability and nutritional quality, innovative food processing technologies are essential. This study investigates the application of ultrasound and thermosonication- emerging non-thermal preservation techniques- to improve the functional properties of broccoli juice. Using Response Surface Methodology (RSM) and Adaptive Neuro-Fuzzy Inference System (ANFIS), the processes were optimised to maximize chlorophyll and ascorbic acid content. Optimal ultrasound parameters (4 min, 91.1 % amplitude) achieved 12.29 mg/100 mL chlorophyll and 79.38 mg/100 g ascorbic acid. Thermosonication (6.9 min, 66 % amplitude, 40 ◦C) gave comparable results. Both treatments significantly improved phenolic composition and mineral content, demonstrating superior preservation of bioactive compounds and reduced nutrient degradation compared to traditional methods. The results highlight the potential of ultrasound and thermosonication for sustainable food systems by improving nutritional quality and shelf life, thereby contributing to reduced food waste and environmentally friendly processing. This research provides valuable insights into the integration of non-thermal technologies in the production of functional beverages, supporting the development of circular food systems and sustainable innovation.Öğe Infation and consumption inequality(Springer Nature, 2025) Daşdemir, EsatThis study investigates the relationship between infation and consumption inequality in the Turkish economy. It utilizes data from household budget and consumption surveys conducted between 2002 and 2023. Lorenz curves and Gini coefcients were calculated to measure consumption inequality across various income and consumption groups, and these metrics are introduced to the literature. The fndings indicate that increases in the consumption share of upper-income groups tend to coincide with periods of heightened infation. The results further suggest that price increases in specifc categories of goods and services can intensify consumption inequality within those categories. Based on the analysis of 12 goods and services groups in the Turkish economy, the presence of both absolute and relative infation in a category is found to increase consumption inequality. In particular, relative price increases are associated with a more pronounced rise in inequality. While a one-unit increase in the infation rate of a category raises consumption inequality by 0.12%, a relative increase in that category’s price raises it by 4.48%.Öğe Nanoliposomal Encapsulation and Purification of AngiotensinConverting Enzyme Inhibitor Peptides from Ulva rigida(AMER CHEMICAL SOC, 1155 16TH ST, NW, WASHINGTON, DC 20036, 2025) Şensu, Eda; Koku, Harun; Demircan, Evren; Şişman, Sebahat; Gülseren, İbrahim; Karaduman, Tuğçe; Çakır, Bilal; Okudan, Emine Şükran; Duruksu, Gökhan; Özçelik, Beraat; Yücetepe, AysunAngiotensin-converting enzyme inhibitory peptides derived from natural sources may be effective in the treatment of hypertension without causing side effects compared with existing angiotensin-converting enzyme (ACE) inhibitors. Naturally derived antihypertensive peptides are therefore considered a promising alternative for the prevention or treatment of hypertension. Therefore, the study aimed to purify and identify ACEinhibitory peptides from the green macroalgae Ulva rigida. In addition, the encapsulation of the purified peptides showed the highest ACE-inhibitory activity by chitosan-coated nanoliposomes, and the characterization of nanoliposomes was evaluated. Protein hydrolysates were obtained from U. rigida through enzymatic hydrolysis. The hydrolysates were separated into molecular weights of <3, <5, and <10 kDa through ultrafiltration membrane separation (UFMS). The <3 kDa fraction (UFMS-3) that exhibited the highest ACE-inhibitory activity (77.02%, 1 mg/mL) was purified using ion-exchange chromatography. Fraction-1 (IEC-F1) obtained from the ion-exchange purification showed an impressive 82.03% ACE-inhibitory activity. Moreover, peptide sequences of IEC-F1 were identified by LC-MS/MS, and their bioactive properties were determined in silico. After that, IEC-F1, with a strong ACEinhibitory activity, was loaded into chitosan-coated nanoliposomes to improve their stability for encapsulation. Physical stability (ζpotential, polydispersity index, particle size), thermal (DSC) and morphological properties (SEM), and FT-IR analyses were carried out for the characterization of nanoliposomes. Encapsulation efficiency was found to be 92.0 ± 4.5%. After encapsulation, the ACEinhibitory activity of IEC-F1 was protected by 37.5%. Overall, the obtained findings indicate that the hydrolysate produced by the successive hydrolysis of U. rigida macroalgae with pepsin and trypsin contains peptides with strong ACE-inhibitory action. Furthermore, the chitosan-coated nanoliposome method was determined to be an effective carrier for the delivery of peptide fractions, showing ACE-inhibitory activity. The formulation of chitosan-coated nanoliposomes for peptide fractions from U. rigida represents an innovative approach that allows the development of functional and stable products.Öğe Comparison of physiological and psychological efficacy of training methods in autism(TZANEIO GENERAL HOSPITAL, ZANNI & 1 AFENTOULI STRS, PIRAEUS GR-18536, GREECE, 2024) Bakan, Kerim; Oral, Onur; Gur, Shanny; Rezaee, Zeinab; Damat, Mertcan; Eroğlu, A.

Furthermore, this study determined the suppressive properties of hemp seed oil on α-amylase, acetylcholinesterase and carbonic anhydrase II that purifed by the sepharose-4B-L-Tyrosine-sulfanilamide afnity chromatoghraphy, all of which are related to diferent metabolic diseases. Moreover, the phenolic concentration in the essential oil was quantifed through LC–HRMS chromatography. Thirteen distinct phenolic compounds were detected in hemp seed oil. Additionally, both the chemical components and quantity of essential oils within hemp seed oil were assessed through GC–FID and GC/MS analyses. Results The predominant essential oils in hemp seed oil included linoleoyl chloride (34.62%), linoleic acid (33.21%), and 2-4-di-tert-butylphenol (5.79%). Hemp seed oil’s ability to scavenge radicals was studied through the use of 2,2’-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) and 1,1-diphenyl-2-picrylhydrazil bioanalytical radical scavenging methods. The results unveiled its potent radical-scavenging properties, with an 46.20 μg/mL for 2,2’-azino-bis(3- ethylbenzthiazoline-6-sulfonic acid) radicals and IC50 of 9.76 μg/mL for 1,1-diphenyl-2-picrylhydrazil radicals. The investigation also extended to explore the reducing capabilities of Fe3+-2,4,6-tri(2-pyridyl)-S-triazine, copper (Cu2+), and iron (Fe3+). Hemp seed oil demonstrated notable inhibitory efect against α-amylase (IC50: 545.66 μg/mL), achethylcholinesterase (IC50: 28.00 μg/mL), and carbonic anhydrase II (IC50: 322.62 μg/mL). Conclusions This interdisciplinary research will prove valuable and set the stage for future investigations into the antioxidant characteristics and enzyme inhibition patterns of plants and plants oils that hold medical and industrial signifcance.Öğe The impact of wealth inequality on inflation and unfair competition among consumers(WILEY, 111 RIVER ST, HOBOKEN 07030-5774, NJ, 2024) Daşdemir, EsatThis study examines unfair competition among consumers according to wealth groups. The study hypothesizes that consumer groups with high income and wealth levels have a competitive advantage over consumer groups with low income and wealth levels, and therefore wealth inequality may create upward pressure on prices. Data from 37 Organisation for Economic Co‐operation and Development member countries covering 2000–2022 were used in the analysis. According to the results of the analysis, increases in the wealth of high‐wealth groups increase the inflation rate more severely.Öğe Applications of Cantor Set to Fractal Geometry(INT ELECTRONIC JOURNAL GEOMETRY, INT ELECTRONIC JOURNAL GEOMETRY, ANKARA 00000, Turkiye, 2024) Karaçay, İpek Ebru; Yüce, SalimFractal geometry is a subfield of mathematics that allows us to explain many of the complexities in nature. Considering this remarkable feature of fractal geometry, this study examines the Cantor set, which is one of the most basic examples of fractal geometry. First of all, the Cantor set is one of the basic examples and important structure of it. First, the generalization of Cantor set in on R, R2 and R3 are taken into consideration. Then, the given structures are examined over curve and surface theory. This approach enables to given a relationship between fractal geometry and differential geometry. Finally, some examples are established.Öğe The Properties of Pectin Extracted from the Residues of Vinegar-Fermented Apple and Apple Pomace(MDPI, ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND, 2024) Muslu Can, Aslı; Metin Yıldırım, Ruşen; Karadağ, AyşeIn this study, both apple slices and apple pomace, the by-product of apple juice processing, were subjected to vinegar fermentation. The pectins extracted from the solid residue of vinegarfermented apple slices (FAP) and apple pomaces (FAPP) were compared to the pectin extracted from non-fermented apple pomace (AP). All samples were classified as high-methoxyl pectins, and vinegar fermentation increased pectin extraction yield. FAP, which has a lower degree of methylation, also exhibited lower thermal stability. The changes in the pectin structure were dependent on both fermentation and the state of the raw material used to produce the vinegar. Compared to AP, the proportion of homogalacturonans (HGs) increased, and the proportion of rhamnogalacturonan I (RG-I) decreased in FAP, providing higher linearity, whereas in FAPP, the RG-I region became more dominant with reduced linearity. The molecular weight distribution of samples showed that pectin from vinegar-fermented sources changed the average molecular weights and mass fraction ratios of two peaks (1255 and 340 kDa) eluted from AP. In FAP, the mass fraction of the first peak (1294 kDa) increased from 35 to 89%, whereas in FAPP, the mass fraction of the second peak (478 kDa) increased to 91%. FAPP showed greater viscosity and a more noticeable shear-thinning behavior. G′ and G′′ in FAPP were also higher than those of AP and FAP at the same concentrations (5%, 7%, and 10% w/v). This study found that applying vinegar fermentation to apple slices and apple pomaces altered the structural and rheological properties of the extracted pectins. FAP and FAPP could be suitable food additives when certain properties are required.Öğe The Nexuses between Community Attachment, Tourism Support, and Cultural Heritage Protection in the Bektashi Faith Destination: The Roles of Perceived Tourism Impacts and Residency Length(ISTANBUL UNIV, METHODOLOGY & SOCIOLOGY RESEARCH CENTER, CENTRAL CAMPUS, ISTANBUL 34452, Turkiye, 2024) Çifçi, Hanife; Boz, Şenay; Demirkol, ŞehnazThis study examines the nexus between community attachment (CA), residents’ perceived positive tourism impacts (POSI), residents’ perceived negative tourism impacts (NEGA), and their attitudes toward support for tourism development (SUPT) and protection of cultural heritage (SUPCH) in the Bektashi faith destination with the moderating role of length of residency. Using a quantitative research approach through the questionnaire technique, 245 eligible questionnaires were analyzed by partial least squares structural equation modeling (PLS-SEM). Findings confirmed the positive relationships among CA, SUPT, and SUPCH. However, only SUPCH positively mediated the relationship between CA and SUPT. Finally, length of residency (LOR) significantly moderated some relationships (i.e., CA and SUPCH; CA and POSI, NEGA and SUPT; and SUPCH and SUPT. Theoretically, this research concluded that CA and LOR are essential determinants of residents’ SUPT and SUPCH. Practically, policymakers and practitioners of faith destinations can develop strategies and take practical future actions.Öğe Do Employees in Turkey Intend to Telework After the Pandemic?(Istanbul Univ, Sch Business, 2023) Bicici, Demet Ozcan; Ozcelik, Ayse OyaMost employees in Turkey have become familiar with teleworking during the pandemic. This study aims to find the Turkish employees' motivation and commitment levels regarding their intention to telework after the pandemic. The mixed method of research with an exploratory sequential strategy with QUAL -> QUAN design was used to explore and explain the motivation and commitment factors regarding the intention to telework after the pandemic in Turkey and to develop a scale. Grounded theory, exploratory factor analysis, one-way ANOVA, and independent samples t-tests were used. The results indicated that age groups affected the motivation and commitment and extrinsic motivation regarding the intention to telework after the pandemic, and education levels affected the general motivation and commitment and intrinsic motivation. As education and teleworking experience levels increased, motivation and commitment and intrinsic motivation regarding the intention to telework after the pandemic increased. Motivation and commitment and intrinsic motivation levels of the employees of companies applying teleworking systematically were higher than the employees who teleworked compulsorily during the pandemic without an adaptation process. Women's extrinsic motivation regarding the intention to telework after the pandemic was higher than men's. The motivation and commitment levels of teleworkers were significantly higher than those of non-teleworkers. The data strongly suggested that childless participants had significantly higher motivation and commitment and intrinsic motivation regarding the intention to telework after the pandemic compared to the parent participants.Öğe The signifcance, potential and the current use of renewable energy in TR83 region, Türkiye(SPRINGER, ONE NEW YORK PLAZA, SUITE 4600 , NEW YORK, NY 10004, UNITED STATES, 2024) Aykut, Ercan; Dursun, BahtiyarThis study aims to present the potential of hydroelectric, wind, solar and biomass sources of the TR83 Region which ensures the sustainability and security of the supply.

Macroalgae Using Green Technology: Effect of In Vitro Digestion on Antioxidant and ACE‑I Inhibitory Activity(AMER CHEMICAL SOC, 1155 16TH ST, NW, WASHINGTON, DC 20036, 2023) Şensu, Eda; Ayar, Eda Nur; Okudan, Emine Şükran; Özçelik, Beraat; Yücetepe, AysunMacroalgal proteins were extracted from Ulva rigida (URPE) (green), Padina pavonica (PPPE) (brown), and Laurencia obtusa (LOPE) (red) using ultrasound-assisted enzymatic extraction, which is one of the green extraction technologies. Techno-functional, characteristic, and digestibility properties, and biological activities including antioxidant (AOA) and angiotensin-I converting enzyme (ACE-I) inhibitory activities were also investigated. According to the results, the extraction yield (EY) (94.74%) was detected in the extraction of L. obtusa, followed by U. rigida and P. pavonica. PPPE showed the highest ACE-I inhibitory activity before in vitro digestion. In contrast to PPPE, LOPE (20.90 ± 0.00%) and URPE (20.20 ± 0.00%) showed higher ACE-I inhibitory activity after in vitro digestion. The highest total phenolic content (TPC) (77.86 ± 1.00 mg GAE/g) was determined in LOPE. On the other hand, the highest AOACUPRAC (74.69 ± 1.78 mg TE/g) and AOAABTS (251.29 ± 5.0 mg TE/g) were detected in PPPE. After in vitro digestion, LOPE had the highest TPC (22.11 ± 2.18 mg GAE/g), AOACUPRAC (8.41 ± 0.06 mg TE/g), and AOAABTS (88.32 ± 0.65 mg TE/g) (p < 0.05). In vitro protein digestibility of three macroalgal protein extracts ranged from 84.35 ± 2.01% to 94.09 ± 0.00% (p < 0.05). Three macroalgae showed high oil holding capacity (OHC), especially PPPE (410.13 ± 16.37%) (p < 0.05), but they showed minimum foaming and emulsifying properties. The quality of the extracted macroalgal proteins was assessed using FTIR, SDSPAGE, and DSC analyses. According to our findings, the method applied for macroalgal protein extraction could have a potential the promise of ultrasonication application as an environmentally friendly technology for food industry. Moreover, URPE, PPPE, and LOPE from sustainable sources may be attractive in terms of nourishment for people because of their digestibility, antioxidant properties, and ACE-I inhibitory activities.Öğe Implementation of Content and Language Integrated Learning and Its Effects on Student Motivation(UNIV SABANA, FAC ENFERMARIA, CAMPUS UNIV PUENTE COMUN, KM 21 AUTOPISTA NORTE BOGOTA, D C, CHIA, CUNDINAMARCA 00000, COLOMBIA, 2018) Mede, Enisa; Çınar, SenanurThe aim of the present study is to examine the effects of integrating Content and Language Integrated Learning (CLIL) on the motivation of students learning English in a preparatory school at a private university in Istanbul, Turkey.

These developments in information technologies have also affected the architecture. Artificial intelligence applications are encountered in many areas such as pricing estimation, energy conservation security systems of buildings, ventilation systems, user-oriented interactive design solutions, computer-aided programs used in the plan production phase and design process. When the literature on artificial intelligence applications in the architecture is reviewed, it can be seen that it generally includes shape grammars, graph theory, decision trees, constraint-based models, machine learning methods, RNN (Recursive Neural Networks), CNN (Convolutional Neural Network) and GAN (Generative Adversarial Network) algorithms. In this study, the use of artificial intelligence algorithms in architecture was examined, and an example was designed to determine the architectural structures of different periods by using CNN (Convolutional Neural Network). In the study, the open source TensorFlow library developed by Google and the Python programming language were used. Employing a statistical approach and utilizing convolutional neural networks (CNNs), a study has successfully classified the current flow patterns of buildings based on datasets comprising facades of Gothic, Modern, and Deconstructivist architectural styles. The findings demonstrate the efficacy of CNNs in accurately distinguishing the intricate details of diverse architectural styles. Recognizing elements from different periods using the CNN algorithm can examine not only individual buildings but also the relationship of buildings with their environments. It can also gain an important place in the field of conservation of the architectural discipline. The historical processes, aesthetic features and changes of protected buildings can be learned with the CNN algorithm and can guide restoration decisions. As a result of the study, the employed CNN-based model can correctly classify structures with 84.66% accuracy rate.Öğe Characterization of chemical, molecular, thermal and rheological properties of medlar pectin extracted at optimum conditions as determined by BoxBehnken and ANFIS models(ELSEVIER SCI LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, OXON, ENGLAND, 2019) Al-Amoudi, Rami H.; Taylan, Osman; Kutlu, Gözde; Muslu Can, Aslı; Sağdıç, Osman; Dertli, Enes; Yılmaz, Mustafa TahsinIn this work, response surface methodology and adaptive neuro-fuzzy inference system approaches were used to predict and model effect of extraction conditions of pectin from medlar fruit (Mespilus germanica L.). The pectin extracted at optimized conditions (89 °C, 4.83 h and 4.2 pH) could be classified as high methoxyl pectin. Sugar composition analysis showed that pectin was mainly composed of D-galacturonic acid, L-arabinose, L-rhamnose, D-galactose and D-glucose. Fourier Transform Infrared Spectroscopy, RAMAN and nuclear magnetic resonance spectra confirmed molecular structure, revealing presence of D-galacturonic acid backbone. X-ray diffraction patterns revealed an amorphous structure. Differential scanning calorimetry showed endothermic (123 °C) and exothermic peaks (192 °C). Thermogravimetric analysis revealed three decomposition regions, 50–225 °C, 225–400 °C and 400–600 °C. Steady and dynamic shear analyses revealed that pectin had a pseudo-plastic behavior with storage (G?) and loss (G?) modulus increasing with increment in frequency, indicating viscoelastic structure more predominantly elastic than viscous.
