Effects Of Storage Regimes On Chemistry, Functional Properties, And Vitamin Profile Of Different Varieties Of Chickpea, Shirin Kazemzadeh Pournaki
Effects Of Storage Regimes On Chemistry, Functional Properties, And Vitamin Profile Of Different Varieties Of Chickpea, Shirin Kazemzadeh Pournaki
Electronic Theses and Dissertations
Chickpea (cicer arietinum) samples from five distinct varieties (crown, royal, orion, sierra, and frontier) were subjected to varying storage conditions to investigate the impact of temperature and relative humidity (rh) on their chemical, functional, physical properties, and vitamin b profile. over 360 days, samples were stored at two temperatures (21°c and 40°c) and three rh levels (40%, 55%, 65%), with collections made every 90 days. initial observations focused on key chemical properties including moisture, protein, fat, and total starch content. subsequently, protein and starch fractions were isolated for further analysis, employing techniques such as sodium dodecyl sulfate-polyacrylamide gel electrophoresis (sds-page) …
Valorization Studies On Ice-Cream Wastewater And Whey Permeate, Maryam Enteshari
Valorization Studies On Ice-Cream Wastewater And Whey Permeate, Maryam Enteshari
Electronic Theses and Dissertations
Ever growing demand for dairy products in many countries has led to advancements in the manufacture of such products. Nowadays, revolutionary trends for high-protein dairy foods and drinks products have brought about new challenges from processing requirements and manufacturing aspects. Using different membrane processing has enabled dairy manufacturers to produce different fraction of milk proteins such as micellar caseins, ultra-filtered (UF) milk proteins, whey proteins concentrate (WPC), and micellar casein concentrate (MCC) to meet the nutritional needs with variety of milk product options. However, the installation of new processing lines and establishing further manufacturing steps requires more consumption of water …
Application Of Analytical Techniques In Food Product Development, Sonali R. Pandey
Application Of Analytical Techniques In Food Product Development, Sonali R. Pandey
Electronic Theses and Dissertations
Products are analyzed in major sectors of food industry to meet regulatory standards, food safety, quality control, and research and development. Analytical and extraction techniques have been applied for simultaneous investigation of multiple product characteristics. Food analysis faces critical challenges due to the complex composition of food, leading to matrix effects that result in loss of accuracy and reliability. The analytical techniques require an efficient sample preparation to avoid or minimize matrix effects. Solid-phase extraction has been widely used to address this issue. In this dissertation, the aim is to apply analytical techniques in food product development. To accomplish this, …
Effect Of Mineral Ions On The Functional Properties Of Starch Films, Aliza Sigdel
Effect Of Mineral Ions On The Functional Properties Of Starch Films, Aliza Sigdel
Electronic Theses and Dissertations
Essential minerals are indispensable inorganic micronutrients that modulate vital physiological functions at the molecular level. Their deficiency, though required in small amounts, impairs health significantly. Their supplementation through diet is prudent and carbohydrates standout as favorable choice. Carbohydrates, starches and polysaccharides, exhibit unique chemical structures and functionalities, and interact with mineral ions in several ways. The aim of this research is to investigate the effect of mineral ions on the physicochemical properties, tensile strength and in vitro starch digestion of starch-films. Corn starch and potato starch along with Fe2+, Mn2+, Cu2+ and Zn2+ ions have been chosen as model starch …

Use Of Extraction Technologies In Food Safety Studies, Changling Qiu
Electronic Theses and Dissertations
Food safety has become a top concern in our society. The public in general is increasingly concerned about the safety of the food products they consume every day as more and more food contamination incidents and widespread recalls arise. It is necessary to trace any presence and/or the concentration levels of contaminants, pesticides, herbicides, or other harmful substances in food samples. Sample preparation is a crucial step in a food analytical method, as it takes up most of the total analysis time, contributing highly to the total cost of analysis and greatly influencing the results of the analysis. Traditional extraction …
The Effect Of Freezing As A Storage Method On Anthocyanin Concentration In Blueberries, Marin E. Plumb
The Effect Of Freezing As A Storage Method On Anthocyanin Concentration In Blueberries, Marin E. Plumb
Undergraduate Honors Papers
Blueberries are rich in a water-soluble class of pigments known as anthocyanins which are known antioxidants. Antioxidants help prevent many diseases by stabilizing free radicals, but are prone to losses in food during storage. The goal of this study was to test the effect of freezing as a storage method on anthocyanin concentration and antioxidant activity over time. Blueberries from Canada and Argentina were frozen for up to 5 months and periodically tested for anthocyanin concentration and antioxidant activity. Anthocyanins were extracted using a mixture of methanol, acetic acid, and water, and evaporation under vacuum. They were separated using column …
