Milk, Cream and Malai FSSAI Standards
Milk:- Milk is the normal secretion of the mammary gland of mammals. India has the largest livestock population in the world and ranks high in milk production. India Produces 187.7 million tonnes of milk in 2018-19. Per capita, milk availability In India is 394 gms/day. (Source: Basic Animal Husbandry Statistics, DAHD&F, GoI). U.P. is the top milk-producing state of India with the production of more than 30 million tonnes. However, more than 50% of the milk sector is still unorganized.

Definitions
LTLT (Low-temperature long time): It involves holding the milk for 62.80C for 30 minutes to eliminate Coxiella burnetii, responsible for Q fever which can be transmitted in milk. It is vat pasteurization method.
HTST: (High temperature and Short time): The use of plate heat exchangers and a continuous operation involves the high-temperature-short-time (HTST) pasteurization process at a temperature of at least 720C for at least 15 sec.
Ultrahigh temperature (UHT): Temperatures of at least 137.80 C in a continuous flow, with holding times of approximately 2 sec to be labelled "ultra-pasteurized."
for cream:
Heating is at 71.10 C or above for 30 min by the holding method or
87.7 to 93.30 C for a few seconds by the
HTST method.
Vacreation: Rapid heating of cream is accomplished by injecting steam or by a combination of steam injection and evacuation in a process known as vacreation.
Sterilisation : The term “sterilisation when used in association with milk, means heating milk in sealed container continuously to a temperature of either 1150 C for 15 minutes or at least 1300 C for a period of one second or more in a continuous flow and then packed under the aseptic condition in hermetically sealed containers to ensure preservation at room temperature for a period not less than 15 days from the date of manufacture
RECOMBINED
MILK = Milk fat + Milk SNF + Water +
homogenization + Pasteurisation. Recombined milk shall be pasteurised and
shall show a negative Phosphatase Test.
SKIMMED MILK
means milk from which fat has been removed mechanically and contains little or
no fat.
Note: The
total urea content in milk shall not be more than 700 ppm.

Cream: Cow
or buffalo milk fat obtained by direct centrifugation of milk. It shall be free
from starch and other ingredients foreign to milk. It may be of the following three
categories.
1. Low fat cream—containing milk fat, not less than
25.0 % by weight.
2. Medium fat cream—containing milk fat, not less than
40.0 % by weight.
3. High fat cream—containing milk fat, not less than
60.0 % by weight.
Note:- Cream sold without any indication about milk
fat content shall be treated as high fat cream.
A mixture of
milk and milk fat of 10 to 12 % is called half-and-half.
