The heat stability of milk passes through a maximum and a minimum as the pH is increased from to The position of the maximum was displaced slightly towards the acid side with addition of phosphate, and slightly towards the alkaline side with addition of calcium, but the maximum heat stability attainable was only slightly affected by small additions (up to 3 mM/liter) of these ions.

The results showed that buffalo, cow, goat milk are non- significantly different from each other but sheep milk is significantly different from all other three species. Usually, ga in paradise lost pdf are more likely to consume or drink Ultra Heat Treated Milk UHTMilk or ultra-pasteurization. Dairy Federal Bulletin, pp: Since a single microbial cell of an organism capable of growth in UHT milk maycause spoilage in a container when the product may be stores for six months or more atambient temperatures, the methods used for detecting contamination must be very sensitive.

As the pH falls below about , a large amount of deposit is formed. Milk with high contents of β-casein are more prone to deposit formation. but the addition of pyrophosphates to milk brings about a significant improvement. IMPORTANT PROPERTIES OF MILK The knowledge of different properties of milk and milk products are required to design the processing and storage structures for milk.

Milk is typically in the range of pH to Values above this range may suggest illness in the cow, while values below this range may indicate that lactic acid fermentation has begun 7. Low pH will render a cheese devoid of shape, while high pH will produce a brittle, crumbly cheese. Yogurt Cultured milk must be brought to a pH value of or lower before being cooled.

Fresh cow milk has a pH of between and Therefore, it is slightlyacidic. Values higher than denote of mastitic milk while values lower than denote thepresence of bacterial deterioration. As milk . Milk in legal terms (PFA) may be defined as whole, fresh,clean, lacteal secretions, obtained by complete milking of one or more healthy milch animals, excluding that obtained 15 days before or 5 days after or such periods as may be necessary to render the milk.

At the normal pH of milk - , the protein remains dispersed evenly in the solution. As the pH is lowered by the addition of an acid, the protein can no longer remain in solution, and it coagulates into an insoluble mass. The pH where this occurs for milk is at about 1 pH Values of Common Foods and Ingredients N o te: Variation exists between varieties, condition of growing and processing methods.

A pH scale measures the acidity or alkalinity of a substance. the pH of, say, 10 ml of the milk to a standard pH, usually , is recorded as the “acidity,” the measurement of pH being performed elect rometrically and not colorimetrically. The effect of adding increasing amounts of phenolphthalein has also been studied, as it is now well known that, with decreasing amounts of the indicator, the pH to which it is necessary to titrate the milk before a. As shown in Table 2 in results, the pH values of cow milk () and of buffalo milk () showed almost similar results observed by Gervilla et al.[ls\ who studied the pH of bovine milk () but value of goat () and of sheep milk () showed little variation. Campbell and Marshall[13] found the maximum value of milk containing a higher apparent acidity is %. In the present study. protein is zero. This pH is called the isoelectric point of the protein (pH for casein). If an acid is added to milk, or if acid-producing bacteria are allowed to grow in milk, the pH falls. As the pH falls the charge on casein falls and it precipitates. Hence milk curdles as it sours, or the casein precipitates more completely at low pH. The pH and/or acidity of a food are generally used to determine processing requirements and the applicability of GMP regulations for regulatory purposes. Methods and conditions for determining the pH and acidity of foods are also summarized in 21 CFR Item Approximate pH Abalone - Abalone mushroom - Ackees Aloe vera Aloe Juice - Anchovies Milk in legal terms (PFA) may be defined as whole, fresh,clean, lacteal secretions, obtained by complete milking of one or more healthy milch animals, excluding that obtained 15 days before or 5 days after or such periods as may be necessary to render the milk.
