The paper deals with the performance optimization for skim milk powder unit of a dairy plant at National Dairy Research Institute (N. D. R. I.), Karnal using Genetic Algorithm (G. A.). The skim milk powder unit comprises of six subsystems working in series. The failure and repair rates of the subsystems are taken from maintenance history sheets, which follow the exponential distribution. The ma...

This study investigated the effects of skim-milk supplementation on the quality and penetrating ability of boar semen preserved at 15 °C. When boar semen samples were preserved in Modified Modena extender supplemented with various concentrations (0, 7.5, 15, 30 and 50 mg/mL) of skim milk powder at 15 °C for 4 weeks, higher sperm motility and viability were observed in the case of 7.5 mg/mL skim...

Coconut milk was prepared by grinding coconut with water and straining through muslin cloth. To improve total solids and protein contents of coconut milk, various temperatures and pH levels of extraction water were investigated. Coconut milk prepared by grinding coconut with hot water (80C) at pH 8 contained highest solids and proteins. The coconut milk was then blended with various percentages...

The microflora of milk powder consists of a wide array of microorgan­ isms of which special attention is given to Bacillus endospores. Bacillus endospores survive pasteurization and spray drying and inhabit the final powder product in the dormant state indefinitely. Once the powder is re­ constituted, endospores may germinate, and through their enzymatic ac­ tivity become detrimental to quality...

BACKGROUND Previous studies have reported that up to 75 % of milk allergic subjects tolerate heated milk products. However, the food used for heated milk challenge is often prepared in a non-standardized manner by the parents at home, which may prove inconvenient and even sometimes raise concerns with regards to test validity. Instant skim milk powder is made by a food process that involves hea...

To produce novel cheese-like fermented soybean, the solid-state fermentation of roasted soybean flour (RSF) was performed using 1.0% inoculum Bacillus subtilis HA and Lactobacillus plantarum, with the initial 60% substrate moisture for 10 hr at 42°C, resulting in pH 6.5, 0.82% acidity, 3.5% mucilage, 14.3 unit/g protease activity, 7.6 unit/g fibrinolytic activity, 216 mg% tyrosine content and 1...

as a native fermented dairy drink, doogh is an important industrial product in iran. however, its characteristics have not been completely evaluated. this study evaluated the flow behavior, particle size distribution and stability of non-fat doogh as affected by the row material employed (fresh skim milk or skim milk powder) and the total solids (ts) content of the final drink. the viscosity of...

Only small numbers of calves were fattened on whole milk alone, both in western Europe and Great Britain, until the 1960’s, d-hen suitable milk-substitute diets were developed. The lorn iron content of milk made calves anaemic (Blaxter, Sharman & MacDonald, ‘957) and lowered the myoglobin content of the muscle tissues. This resulted in white meat. In the course of time this whiteness bccame a m...

Milk proteins have many potential sequences within their primary structure, each with a specific biological activity. In this study, we compared and investigated the bioactivities of hydrolysates of the domestic (A, B) and imported (C, D) skim milk powders generated using papain digestion. MALDI-TOF analysis revealed that all milk powder proteins were intact, indicating no autolysis. Electropho...

Pasteurization parameters for grade A milk are well established and set by regulation. However, as solids levels increase, an increased amount of heat is required to destroy any pathogens present. This effect is not well characterized. In this work, the effect of increased dairy solids levels on the thermal resistance of Listeria monocytogenes was examined through the use of ultrafiltered (UF) ...
