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 …

Extractable-Emulsifying Capacity Of Hand And Mechanically Deboned Mutton And Organoleptic Acceptability Of Various Mutton Salami Formulations, Jack Robert Anderson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Salt soluble extracts from mechanically deboned mutton were significantly higher (P < .01) in pH than the extracts from the hand boned mutton. An associated trend toward greater extractability, however, was not significant. Variation in emulsifying capacity between extracts from carcass parts were highly significant yet significant variation did not occur in the emulsifying capacity of hand versus mechanically deboned mutton. A new term, extractable- emulsifying capacity is presented which incorporates the extractability and emulsifying capacity of meat extracts into one value which should more accurately estimate the contribution of a meat ingredient in forming a stable sausage emulsion.

Salami, utilizing mutton, was formulated from experimental results which indicated that up to 10 percent mutton fat and 68 percent mutton lean was acceptable to panelists. Pork was preferred to beef for use in combination with mutton as determined by panel scores, however disagreement was noted between panelists. Panelists were unable to detect flavor, moisture or texture differences between the final mutton salami and a commercial beef and pork formulation. They did however prefer the appearance of the mutton salami (P < .05).

Effect Of Added Calcium Ions On Relative Milk-Clotting Activities Of Commercial Milk Clotting Enzymes, Nuchanart Pavenayotin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Effect of added calcium ions on the relative milk clotting activities of porcine pepsin, Mucor miehei protease, Endothia parasitica protease, and Mucor pusillus protease was compared with that of rennin. Skimmilk, maintained at pH 6. 3 with 0.000% to 0.030% added calcium chloride, was used as a substrate. The coagulation activity of Mucor pusillus protease appeared to be most sensitive to calcium ions, followed by Mucor rniehei protease, porcine pepsin, rennin, and Endothia parasitica protease. The clotting activities of Mucor pusillus protease were also more sensitive than rennin to added calcium ions in milk samples maintained at pH values of …

Formation And Anatomical Distribution Of Chlorophyll And Glycoalkaloids In Potato (Solanum Tuberosum L.) Tubers And Their Control By Physical And Chemical Treatments, Robert Bruce Jeppsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Applications of growth regulators and modifications of light exposures were investigated regarding their abilities to curtail the normal development of chlorophyll and glycoalkaloids in potato tubers responding to light. Four growth regulators were sprayed on the foliage of potato plants 14 days prior to harvest, of which two (Ethephon and N⁶-Benzyladenine [N6BA]) successfully retarded chlorophyll and glycoalkaloids in the harvested tubers. When tubers were dipped in N6BA, lower concentrations of the chemical promoted glycoalkaloid formation, while larger amounts were more inhibitory. When fluorescent lights were directed through colored cellophane filters, tubers receiving yellow and orange illuminations were inhibited …
