milk and milk products Flashcards
Heating to sufficient temperature below 100°C and time combination to destroy pathogenic bacteria. Also destroys enzymes for increasing shelf life
Pasteurization
Heating to very high temperatures to destroy both pathogens and spoilage microorganisms that can proliferate under ordinary stage conditions
Ultra-pasteurization / sterilization
Heating at very high temperatures and packaging in sterile packaging while inside sterile chambers
Ultra High Temperature Processing (UHT)
Addition of certain nutrients like vitamin A and vitamin D to milk as a means of improving the nutritional value
Fortification
Permanently disperse fat globules of milk to prevent separation upon standing
Homogenization
Centrifuge operation to separate the milkfat/butterfat to produce low fat or reduced fat milk
Milkfat removal
Removal of half of the water content
Evaporation
Removal of practically all the water content to produce a dry powder
Drying
Is a milk whose composition has not been altered from the time it was collected from the milk animal. It may be raw, pasteurized or or sterilized
Whole Milk
Is fresh whole milk that has not undergone any heat treatment. Availability is generally limited to families who own milking animals such as carabaos, goats, or dairy cattle.
Raw Milk
Is fresh whole milk which has been heated to temperatures high enough to kill pathogenic microorganisms to prolong its storage life; but not high enough to significantly alter the organoleptic qualities of the milk.
Pasteurized milk
Is whole milk that has undergone heating at temperatures much higher than the 100°C (212°F) for a few seconds.
Sterilized whole milk
This is 100% natural milk processed by rapid heating to a temperature range of 135°C - 150°C in continuous flow and held at that temperature for several seconds to ensure commercial sterility.
Ultra high temperature (UHT) milk
Non fat milk in liquid form has most of the fat removed thus reducing the fat content to about less than one percent of the whole milk. (Fortified with vitamins A and D)
