Role Of Exopolymeric Substances In Biofilm Formation On Dairy Separation Membranes, Nuria Garcia-Fernandez
Role Of Exopolymeric Substances In Biofilm Formation On Dairy Separation Membranes, Nuria Garcia-Fernandez
Electronic Theses and Dissertations
In the concentration of cheese whey by membrane filtration processes, fouling is a major limiting factor that leads to flux decline and affects product quality. The growth of biofilms on membranes contributes to biofouling. Biofilms are very difficult to eliminate, and will serve as the seed for additional biofilm development and product contamination. The biofilm matrix is composed mainly of microbial exopolymeric substances (EPS), and therefore EPS is thought to help bacteria to adhere and form biofilms by acting as a cementing agent. The first research project under this study was conducted with the aim of elucidating the role of …

Effects Of Bran Treatment On Rheology And Sensory Quality Of Whole Wheat Flat Bread, Jigyasha Mishra
Electronic Theses and Dissertations
The purpose of this research was to study the differences in the quality of 100% whole wheat flour (WWF) when the bran fraction was subjected to mild solvent treatment before reconstitution with the endosperm. The bran treatments included water washing and washing with ethanol solutions (50% and 100%). WWF prepared with untreated bran served as the control. Effects of these treatments on particle size, chemical composition, color, dough rheology, product formulation, and sensory characteristics of 100% whole wheat flour were studied. Grains of five HRSW cultivars (Advance, Prevail, Select, Brick and Forefront) were milled using a Quadrumat Senior mill. Gluten …
Three Overlooked Issues: Water Quality, Forage Quality, And Forage Blends Impacting The Feed Efficiency Of Dairy Cows, Ishwary Prasad Acharya
Three Overlooked Issues: Water Quality, Forage Quality, And Forage Blends Impacting The Feed Efficiency Of Dairy Cows, Ishwary Prasad Acharya
Electronic Theses and Dissertations
The overall objectives of the six studies were to increase the feed efficiency in lactating dairy cows. The first study evaluated the efficacy of different water sources and treatment systems on ruminal parameters using an in vitro gas production system. Outcomes of the study suggested that the source and nutrient quality of water can affect rate of ruminal fermentation. Thus, use of real farm water being offered to the cow to conduct in vitro gas production measurements may accurately predict the ruminal fermentation, digestibility and total gas production. The second study evaluated two recently developed leafy-floury corn silage hybrids against …

Manufacture, Concentration, And Functionality Of Micellar Casein Concentrate, Dustin Grossbier
Electronic Theses and Dissertations
This research has been structured into 3 major parts. The first part evaluates a centrifugal evaporator to concentrate micellar casein concentrate (MCC). The second part evaluates a wiped film evaporator (WFE) to concentrate MCC. The third part evaluates heat stability of the high concentration MCC produced by WFE. In part 1, the primary objective was to achieve >25% total solids (TS) without a loss of water removal rate associated with high solids materials. This is of importance, industrially, as this could reduce processing costs or eliminate drying all together. The major finding was that it did not offer any benefits …
Study Of The Effect Of Feeding Highly Digestible Corn Based Calf Starter On The Growth Performance Of Calves, Shruti Srivastava
Study Of The Effect Of Feeding Highly Digestible Corn Based Calf Starter On The Growth Performance Of Calves, Shruti Srivastava
Electronic Theses and Dissertations
New corn hybrids have been developed by Masters Choice (MC) that vary in energy density and starch digestibility. These MC hybrids have lower starch densities due to an altered starch structure, which allows for greater ruminal and intestinal starch digestion. The altered starch structure of these new hybrids results in reduced feed manufacturing costs (i.e., grinding). Thirty (30) 1 to 3 d old (40.6 ± 1.72 kg) Holstein heifer calves were randomly assigned to 1 of 2 calf starters to measure growth performance of Holstein heifer calves through 8 weeks of age. Treatments were: 1) Hard starch (HS) corn calf …
