Homogenization And Thermal Processing Reduce The Concentration Of Extracellular Vesicles In Bovine Milk, Anna P. Colella, Anuradha Prakash, John Miklavcic
Food Science Faculty Articles and Research
Extracellular vesicles (EVs) in bovine milk confer beneficial physiologic effects to consumers. Industrial processing treatments may affect the amount or bioactivity of EVs intrinsic to bovine milk. We investigated how the content and concentration of EVs were affected by homogenization and thermal processing of raw bovine milk. Raw milk was processed by homogenization, low-temperature (LT) heat, or pasteurization [high-temperature short-time (HTST) and ultra-high-temperature (UHT)] in a pilot processing facility. EVs were isolated from the raw and processed bovine milk using differential ultracentrifugation and quantified using a nanoparticle tracking analyzer. Bovine milk EVs were assessed for total miRNA and protein concentrations …

Membrane filtration has been used extensively by the dairy industry to produce a variety of dairy ingredients from milk. MCC manufactured from freshly pasteurized milk can be directly consumed or as a supplement to fortify and enhance nutritional qualities in processed food …
A Process To Produce Lactose Phosphate From Dairy Byproducts And Used As An Alternative To Emulsifying Salts In Processed Cheese Food Manufacture, Khalid Ahmed Alsaleem
A Process To Produce Lactose Phosphate From Dairy Byproducts And Used As An Alternative To Emulsifying Salts In Processed Cheese Food Manufacture, Khalid Ahmed Alsaleem
Electronic Theses and Dissertations
Lactose is the primary carbohydrate in most mammals' milk, commonly known as milk sugar. Milk permeate is a by-product of whey protein manufacturing through membrane technologies. It is cost-effective, available, and an excellent source of lactose. Sugar phosphorylation is a technique used to alter sugar's characteristics. It has numerous applications for developing dairy and food products. Lactose-6-phosphate (LP) is an organic compound that switches the hydrogen on lactose by monophosphate that has the potential to function as emulsifying salts (ES). ES, such as disodium phosphate (DSP) and trisodium citrate, have a critical effect on the emulsification characteristics of casein by …

Casein Micelles And Their Properties: Polydispersity, Association With Vitamin A And Effect Of Ultra-High Pressure Homogenization, Maneesha Sheenu Mohan
Doctoral Dissertations
The internal structure of casein micelles is not fully understood. In the present work, we explore some of the basic questions about casein micelles in bovine milk including its size distribution, native binding properties and effect of ultra-high pressure homogenization (ultra-HPH) on technological properties of casein micelles. The size distribution of casein micelles was studied by cryo-TEM using skim milk from four cows. The degree of variation in casein micelle sizes (polydispersity) ranged between 0.39 and 0.47 for a size distribution ranging from 10 to 693 nm. These results indicated high polydispersity of casein micelles in milk from single cows. …

Tracking Heat-Resistant, Sporeforming Bacteria In The Milk Chain: A Farm To Table Approach, Maricarmen Estrada Anzueto
Department of Food Science and Technology: Dissertations, Theses, and Student Research
Sporeforming bacteria (such as Bacillus and Paenibacillus spp.) can survive pasteurization conditions (Collins, 1981) and grow in pasteurized fluid milk during refrigerated storage (Huck et al., 2008; Ivy et al., 2012), causing fluid milk spoilage and limiting the further extension of fluid milk’s shelf life (Fromm and Boor, 2004; Durak et al., 2006). Moreover, Bacillus and related genera have been found in raw milk, pasteurized milk and environmental samples from dairy farms, indicating that these organisms are ubiquitous in nature and can enter the milk chain from different sources (Huck et al., 2007b; Huck et al., 2008; Ranieri and Boor, …

The Cost Of Affordable Food, Candice L. Cobuzzi
SURGE
When someone puts a piece of food in front of me, I don’t just see a piece of food.
Instead, I see an innocent cow being cornered by a forklift and slaughtered, its limp, moist tissue hung on a long conveyer belt with hundreds of others.
I see hundreds of chemically-injected chickens packed into a dark barn with no hope of seeing sunlight in their lifetime.
I see immigrants pulled from their houses like criminals, taken away from the lives they’ve spent years building for themselves and their families, working for the same food company that courted them into the …
Detecting Errors In Generating A Certificate Of Analysis, Breanne Harlan
Detecting Errors In Generating A Certificate Of Analysis, Breanne Harlan
Dairy Science
Many companies rely on a Certificate of Analysis (COA) to accompany the delivery of their product or material. The COA, required by law, prevents customers from questioning whether a product is safe and ensures manufacturers confirm every product tested passes the Food and Drug Administration’s required specifications. Previous to this project, Kraft Foods Springfield copied their test results for each product from their data warehouse software, called Systems, Applications, and Products onto a Word document to create a COA. This was a systematic approach to detect the possible occurrences of error and reduce the time spent on generating a COA. …

Light Backscatter Of Milk Products For Transition Sensing Using Optical Fibers, Frederick A. Payne, Czarena L. Crofcheck, Sue E. Nokes, Klat C. Kang
Biosystems and Agricultural Engineering Faculty Publications
Transition sensors are needed, particularly in the dairy industry, for detecting transitions in pipe flow systems from product-to-water or product-to-product (such as from chocolate to vanilla ice cream mix). Transition information is used to automatically sequence valves to minimize product waste. Optical fibers were used to measure light backscatter between 400 and 950 nm as a function of milk concentration in water and milkfat concentration in milk. The normalized response (100% for product and 0% for water) as a function of product concentration in water was approximately logarithmic for skim milk between 400 and 900 nm and approximately linear for …

Predicting The Cutting Time Of Cottage Cheese Using Backscatter Measurements, Czarena L. Crofcheck, Frederick A. Payne, Sue E. Nokes
Biosystems and Agricultural Engineering Faculty Publications
An automated system for monitoring culture growth and determining coagulum cutting time is needed for cottage cheese manufacturing. A light backscatter measurement system was designed and installed in a local cottage cheese manufacturing plant. A cutting time prediction algorithm was developed using parameters generated from the backscatter profile. The cutting time prediction algorithm, Tcut = Tmax + β2 S, used two time-based parameters generated from the backscatter profile (Tmax and S) and one operator selected parameter, β2, to predict the coagulum cutting time, Tcut. The standard error of prediction for the algorithm was 6.4 …

Ahmad Salihin Hj Baba
The effects of supplementation with mixed fodder or concentrate were investigated on the performance of a) growth of male lambs;md kids grazing extensively under oil palm trees and b) reproduction of ewes and goats stall-fed with native herbage. Supplemented kids and lambs had higher average daily weight gain than controls but the effect was only significant for those which received concentrate (p < 0.05). Final body weight was only significantly different from controls for lambs supplemented with concentrate (p < 0.05). The ages at puberty, first mating, first conception and first kidding of supplemented goats were about 110 days earlier than those for controls (p < 0.05 or better). Supplemented goats had first mating and conceived at lower body weights (p < 0.01) than those in control groups. Different feeding regimes had no effects (p > 0.05) on the reproductive performance of ewes apart fi om highest body weight of first lambing in animals supplemented with concentrate (p < 0.05). Native herbage available under oil palm trees of 5 years old was sufficient for growth …
Uht Milk : Expanding The Market, Caroline Love, Ian Bell, Martin Robertson
Uht Milk : Expanding The Market, Caroline Love, Ian Bell, Martin Robertson
Journal of the Department of Agriculture, Western Australia, Series 4
An increase in the export of UHT (Ultra Heat Treated) milk to Asian markets is potentially worth millions of dollars to the dairy inmdustry. This increase however, relies on the shelf life of UHT products being extended to nine months. Spoilage of UHT milk can be caused by bacterial spores which originate on-farm and are resistant to processing. Expansion in the UHT market therefore relies on a continued reduction in the number of these spores getting into raw milk. Caroline Love, Ian Bell and Martin Robertson report on the sources of spores entering milk on-farm and the control methods available.

Ultrafiltration Of Skim Milk Prior To Cottage Cheese Making, Izhar H. Athar
Electronic Theses and Dissertations
Cottage cheese has the largest sales volume potential of all cultured dairy products in the United States today. Moreover, it can be a highly profitable product if proper control is exercised during its manufacturing (46). Commercial production of cottage cheese utilizes a significant portion of the total fluid milk produced in the U. S.A. After the 1955's, yearly per capita consumption of cottage cheese increased from 1. 7 7 kg (3.9 lb) to a high of 2. 45 kg (5.4 lb) in 1972 (67) . Consumer demand for lower fat dairy products gradually increased, which put more pricing emphasis on …

Varieties Of Cheese, T A. Morris
Bulletins 4000 -
While Cheddar cheese is by far the main type as far as English speaking countries are concerned, it is only one of a large number of varieties of cheese which are becoming more universal in production and consumption. In other than English speaking countries Cheddar cheese is almost unknown and yet the consumption of cheese in some of these countries is very much greater. The naming of cheese types has usually been a result of the use of the name of the place where the cheese was first made. Thus cheeses of similar type but produced in a different locality …

Manufacture Of Monterey Cheese From Preacidified Milk, Faisal O. Mohamed
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Whole milk acidified to pH 5.3 with hydrochloric acid was used for the manufacture of Monterey cheese. The milk was inoculated with one and one-half percent lactic starter and set with 12.5 ml rennet per 1000 pounds of milk. Normal washing treatments resulted in cheese with moisture in excess of 44 percent. Moisture content was brought below 44 percent by using wash water at a temperature such that the water-curd-whey mixture was 35 C. The pH of cheese made by preacidification was all between 5.21 and 5.09. No acid defects were encountered. Preacidification eliminated chance of spoilage or losses caused …
The Influence Of Hot Brine On The Calcium Content, Score, And Physical Properties Of Low-Fat, Cheddar-Like Cheese, Robert V. Ogden
The Influence Of Hot Brine On The Calcium Content, Score, And Physical Properties Of Low-Fat, Cheddar-Like Cheese, Robert V. Ogden
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Two factors that are important in the production of the typical body and texture of cheddar cheese are acid development and milk fat content. When either of these is absent or present in less-than-normal amounts, the resulting cheese shows marked defects of curdiness and firmness.
When acid development in a vat of cheese is arrested, it is referred to as a "dead" vat. The cheese from this vat may be salvaged by use of the hot brine method of treatment. Hot brine treated cheese, although lacking the desired acid development, is a reasonably acceptable product, having the desired characteristics of …
