Modeling The Flow And Creep Compliance Properties Of Ice-Cream Mixes, Hiran Ranaweera
Modeling The Flow And Creep Compliance Properties Of Ice-Cream Mixes, Hiran Ranaweera
Electronic Theses and Dissertations
This work documented the influence of the protein source (MPC80 and WPC80), protein content (4-12%), and temperature (5-35ΒΊC) on the rheological behavior (flow curve, frequency sweep, and creep-recovery) of ice-cream mixes (ICM). For each protein source, the viscosity of the ICM was satisfactorily modeled (π 2>0.98, π 2 πππ>0.98, and E0.99), while the recovery phase was represented by an empirical model. The percentage of recovery (%R) of the ICM significantly decreased with the protein content.
A Natural Antimicrobial From Bacillus Subtilis As A Biosanitizer For Resilient Membrane Biofilms, Pratishtha Verma
A Natural Antimicrobial From Bacillus Subtilis As A Biosanitizer For Resilient Membrane Biofilms, Pratishtha Verma
Electronic Theses and Dissertations
The microbial attachment and colonization on separation membranes lead to biofilm formation. Some selective isolates within the biofilm constitutive microflora acquire resistance and emerge predominant over prolonged use of the membrane. Thus, proving the cleaning and sanitization protocols to be ineffective in adequately removing resilient biofilms. This subsequently leads to selecting microbial resistance within the constitutive microflora to almost all antimicrobial treatments and hence, creates a need to develop novel alternative strategies to control biofilm formation on membrane surfaces. The first research project under this study was designed to understand the microbial interactions and emergence of predominance within biofilm constitutive β¦
Development Of Methods To Improve Lactose Recovery From Permeate And Drying Characteristics Of Greek Acid Whey, Venkateswarlu Sunkesula
Development Of Methods To Improve Lactose Recovery From Permeate And Drying Characteristics Of Greek Acid Whey, Venkateswarlu Sunkesula
Electronic Theses and Dissertations
Growth of higher protein dairy products and ingredients such as cheese, Greek yogurt, whey protein concentrates, and milk protein concentrates is limited by the amount of co-product generated and the ability to process them into value added ingredients. Finding value for all the co-products will help dairy industry to meet the growing demand for dairy protein products and ingredients. Commercial scale evaluation of new technologies for improving lactose crystallization and drying ability of Greek yogurt acid whey will help dairy industry to better utilize different dairy co-products. Commercially, lactose is manufactured from concentrated permeate by cooling and separating Ξ±-lactose monohydrate β¦
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 -12.0Λ C) and duration (0 - 72 h), using regression analysis. Based on initial spiking of vegetative β¦
Effect Of Ultrasonication On Biofilm Forming Ability Of Common Dairy Sporeformers, Taghreed Almalki
Effect Of Ultrasonication On Biofilm Forming Ability Of Common Dairy Sporeformers, Taghreed Almalki
Electronic Theses and Dissertations
Sporeformers are common dairy contaminants, which are of a great concern to the dairy industry. Quality of dairy products is affected by these sporeformers such as Bacillus species, which are a significant cause of spoilage of dairy products. Thermal processes such as pasteurization have been used to inactivate pathogens, but some of the sporeformers and their endospores are resistant to such heat treatments. Beside thermal treatments, various new approaches are being developed to improve the quality of dairy products. Amongst these, ultrasonication is a promising non-thermal technique for the inactivation of thermoduric sporeformers and their endospores. Current study was carried β¦
Proteomics Study Of Pre-Harvest Sprouting In Wheat, Pramod Khadka
Proteomics Study Of Pre-Harvest Sprouting In Wheat, Pramod Khadka
Electronic Theses and Dissertations
Pre-harvest sprouting (PHS) of wheat (Triticum aestivum L.) is a condition characterized by the early germination of spikes during moist environmental conditions. PHS lowers yield, degrades the quality of grain and thus limits the profits of wheat producers groups. During this investigation, proteomics studies of PHS-resistant and PHS-susceptible wheat embryos were conducted at different imbibition time periods via a cutting-edge technology called iTRAQ. Proteomic analysis revealed that 190 differentially expressed proteins might be involved in various cellular functions, such as carbohydrate metabolism, nitrogen metabolism, stress response, redox regulation, ATP synthesis, and protein translation, during this untimely germination of the wheat β¦
