Isolation And Characterization Of Different Aggregates Of Lipid From Bovine Milk, Ankur Jhanwar

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Bovine milk fat globules naturally vary from less than 0.2 µm to 15 µm in diameter. Milk has at least two distinct distributions of fat globules. While the majority (~90%) of globules in milk are of the smaller distribution (average diameter of 0.4 µm), virtually all the fat is carried in the larger globules (average diameter 3.5 µm). This distribution suggests some compositional and/or functional significance might exist between the two populations of fat globules, which may be related to origin of these globules in the lactating cell.

Milk fat globules have a unique structure, composed of a core droplet …

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

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 …
