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 …
Production And Storage Stability Of High Concentrated Micellar Casein And Its Effect On The Functional Properties Of Process Cheese Products, Ahmed Hammam
Electronic Theses and Dissertations
Micellar casein is a high-protein ingredient that can be used in process cheese products (PCP) formulations. PCP is a dairy food prepared by blending dairy ingredients (such as natural cheese, protein concentrates, butter, non-fat dry milk NFDM, whey powder, and permeate) with nondairy ingredients (such as sodium chloride, water, emulsifying salts, color, and flavors) and then heating the mixture with a continuous agitation to produce a homogeneous product with an extended shelf-life. The first objective of this study was to produce a highly concentrated micellar casein (HC-MC) and evaluate its storage stability. Skim milk was pasteurized at 76°C for 16 …
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, …
Influence Of Sporulation And Germination Behavior Of Bacillus Licheniformis On Microbial Quality Of Skim Milk Powder, Nancy Awasti
Influence Of Sporulation And Germination Behavior Of Bacillus Licheniformis On Microbial Quality Of Skim Milk Powder, Nancy Awasti
Electronic Theses and Dissertations
This dissertation includes modeling of sporulation and germination behavior of Bacillus licheniformis strains during raw milk holding, tracking the survival of sporeformers and spores of high sporulating Bacillus strain during skim milk powder manufacturing. In addition, preliminary studies were done to standardize a rapid spore detection technique by using ratiometric fluorescence. To understand the role of strain variability during raw milk holding conditions, population dynamics of two strains of Bacillus licheniformis, ATCC 6634 and 14580, were modeled as a function of temperature (4.0 -12.0˚ C) and duration (0 - 72 h), using regression analysis. Based on initial spiking of vegetative …
Developing Food Quality Standards For Distiller’S Dried Grains – Evaluating Composition Quality And Safety, Tanvee Deshpande
Developing Food Quality Standards For Distiller’S Dried Grains – Evaluating Composition Quality And Safety, Tanvee Deshpande
Electronic Theses and Dissertations
Introduction: Distillers Grains represent a major co-product of corn ethanol production. At the production rate of 44 million tons/year and a price of $95/ton, this co-product has potential as a food ingredient (solvent-treated dried products) owing to its high protein content (38%) and high fiber content (40%TDF). The aim of the research was to determine the composition, quality and safety of several initial moisture types of distiller’s grains – distiller’s grains without solubles (DG) and distiller’s grains with solubles (DGS) in wet and freeze-dried form (FrD) from 2017 and 2018.
Method: Processing methods were optimized for raw DG & DGS …
Assessing Listeria Risk During Different Stages Of Ice Cream Manufacturing And Storage, Neha Singh
Assessing Listeria Risk During Different Stages Of Ice Cream Manufacturing And Storage, Neha Singh
Electronic Theses and Dissertations
Listeriosis is a life-threatening infection caused by foods contaminated with Listeria monocytogenes. Some of the major ice cream recalls in recent years reaffirm the ability of this food-borne pathogen to survive in diverse dairy processing environments and cause cross contamination. Inspection reports revealed certain lapses in implementing adequate hygienic practices for Listeria persistence in the processing environment, leading to cross contamination of ice cream. The higher levels of cross contamination of raw ice cream mix might result in random heat-injured cells when exposed to minimum heat treatment (69°C for 30 min). Evidence about the presence of injured cells in ice …
Hydrodynamic Cavitation As In-Line Process To Control Common Dairy Sporeformers, Pratibha Chaudhary
Hydrodynamic Cavitation As In-Line Process To Control Common Dairy Sporeformers, Pratibha Chaudhary
Electronic Theses and Dissertations
Sporeforming bacteria and their endospores have the ability to survive thermal treatments and proliferate in the milk and dairy products to cause spoilages. We applied the effect of hydrodynamic cavitation in controlling these bacteria and their spores at pilot scale level. Our aim was to investigate a technology that would improve the microbial quality of milk and dairy products, and is capable of being scaled up to be adapted at industrial level. Cavitation damages the cell walls of the bacteria and their endospores (releasing dipicolinic acid, responsible for endospore resistance to extreme conditions), thereby making them susceptible to thermal treatments …
Effects Of Oats And Distiller’S Dried Grains Fibers On Fortification Of Asian Noodles – Evaluation Of Glycemic Response, Noodle Quality And Nutritional Composition, Kara Konst
Electronic Theses and Dissertations
The objective of this study was to develop Asian wheat noodle formulations enriched with oat flour and corn DDG at 10, 20 and 30 % wheat flour replacement levels and to evaluate the effects of this fiber and protein enrichment on the glycemic response of human subjects. We hypothesized that the addition of high-fiber oats and high-fiber, high-protein DDG will have synergistic effects in lowering the glycemic response in human subjects. In this study, steamed instant Asian noodles were prepared with DDG(D) and oats(OF) in combination with all-purpose wheat flour(W) in the following flour blends: (W:D) 90:10, (W:OF) 90:10, (W:D) …
