What Is
UHT Milk
UHT milk is a sanitary and veterinary controlled
milk which is subjected to special thermal treatment (ultra-pasteurisation or
Ultra High Temperature) which destroys germs and preserves vitamins and
nutrients. In the absence of bacteria activity and with the pre-sterilisation of
the packaging, the milk becomes less perishable: through ultra-pasteurisation,
the validity period of milk is prolonged without adding preservatives. The
temperatures lie beyond the boiling point (135 - 150° C) but the boiling time
is very short: 2-4 seconds). This very short stage of heating and cooling
destroys bacteria and microorganisms and ensures the preservation of vitamins
and proteins, unlike the normal boiling of milk, which doesn’t destroy all
germs and bacteria, instead destroying its nutritional value. The validity
period varies between 3-6 months, depending on the quality of the raw milk
collected from farms (deriving from hygiene during milking alongside handling
and storing conditions until the moment of reception in the factory). After unsealing
the box, UHT milk need to be kept refrigerated and consumed within the next 3
days.
UHT is most commonly used in milk production,
but the process is also used for fruit juices, creams, soy, milk, yoghurt, wine, soups, honey, and stews.
Unfortunately, those of you who do your research on
the various milk brands in Singapore will soon find the whole issue of which
cow’s milk to feed baby from the various milk brands in Singapore utterly mind
boggling. Very few people recognize that quite often the wholesome stuff from
Australia or New Zealand that we fork out mega bucks for is actually very low
on nutrients.
Advantages of UHT milk
1. Preserved taste and nutrition - It has been pasteurized at a higher temperature to preserve taste and no loss of nutritional properties during its long validity period.
2. Prevent products from contamination - Using UHT treatment prevents the products from being contaminated by airborne micro-organisms.
3. Increase product shelf life - The product shelf life is longer and can last up to six months without refrigeration or preservatives unless it is opened.
4. Can be bought in large quantities and stored.
