What are the advantages of sterilized milk?
UHT milk is a rich source of a number of essential nutrients including calcium, phosphorus, potassium, riboflavin, zinc, vitamins A and B12, magnesium, carbohydrates, and protein. Sterilisation makes milk lighter as once you have treated milk at ambient temperature, the number of microorganisms turns almost zero.
What is turbidity in milk?
The breaking up of the fat globules causes them to scatter a greater amount of light and gives the milk a more opaque appearance. It has been found that a rough estimation of the total solids of milk can be made by diluting the milk to the range of turbidity which can be measured in a photoelectric colorimetcr (1).
Is sterilized milk good?
The nutritive value of pasteurized and UHT-sterilized milk changes little by the heat treatment and during storage. In-bottle sterilized milk shows a somewhat greater loss of nutritive value. Of special importance are the decrease of available lysine and the total or partial loss of some vitamins.
What effect does the Sterilisation process have on the flavour and appearance of the milk?
What effect does the sterilisation process have on the flavour and appearance of the milk? Results in a burnt, caramelised flavour and browning.
What is the disadvantage of sterilized milk?
THE DISADVANTAGES OF STERILISATION. amount of gastric atony, the infant may be unable to take a sufficient quantity of milk for the purpose of nourishment, and thus may undergo a process of slow starvation.
Which is better sterilized milk or fresh milk?
During the storage of milk, nutrients will be lost over time. Therefore, from a nutritional point of view, pasteurized milk is a better choice. Pasteurization cannot kill all microorganisms in milk, and some microorganisms that are not pathogenic to humans are left behind.
Why do a turbidity test?
Often the turbidity of water is used to assess water quality prior to release into the environment. Turbidity changes in wastewater can indicate that filters are not working correctly or that there is a problem with the water chemistry. It could indicate ineffective disinfection or poor coagulation and flocculation.
What is meant by turbidity?
Turbidity is the measure of relative clarity of a liquid. It is an optical characteristic of water and is a measurement of the amount of light that is scattered by material in the water when a light is shined through the water sample. The higher the intensity of scattered light, the higher the turbidity.
What is the best time to drink sterilized milk?
As per Ayurveda, the best time to consume milk for adults is before bedtime. As for kids, Ayurveda recommends an early morning dose of milk. Drinking milk at night promotes ‘Ojas’. Ojas is referred to as a state in Ayurveda when you achieve proper digestion.

What do you need to know about the turbidity test?
Observation. A clear pale yellow solution was observed. The turbidity test is useful in telling us if a sample of milk is sufficiently sterilized, whereby a clear solution will be observed. The turbidity test is first carried out by adding a denaturing agent, usually ammonium sulphate, (NH4)2SO4, to the milk sample.
What is the titratable acidity of pasteurized milk?
The titratable acidity of pasteurized milk is also observed to be slightly above that of UHT milk by a very minute concentration of 0.001 g/100mL. This suggests that pasteurized milk contains slightly more microbes than UHT milk, which goes in tandem with the properties of pasteurized milk.
