What Is UHT Milk
UHT milk 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.
The difference
between pasteurised and ultra-pasteurised milk
Pasteurisation
involves heating the milk up to a temperature of 72-75° C and keeping it at
this temperature for approximately 15-20 seconds before cooling it. Pasteurised
milk has a validity term of 5-15 days if refrigerated accordingly during
transport and distribution.
Through
ultra-pasteurisation the milk is intensely heated for only 2-4 seconds at a
temperature of 135 - 150°C. The validity
period of milk is prolonged without adding preservatives. The validity period
varies between 3-6 months, depending on the quality of the pure 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 Singapore need to be kept refrigerated and consumed within the
next 3 days.
The UHT
procedure (Ultra High Temperature) is a continuous process which takes place in
a closed system, preventing the product from being re-contaminated with germs
from the air. The product goes through a rapid succession of heating and
cooling stages. The aseptic filling is part of the process which prevents
recontamination. The final result is a product which can be kept for about six
months without refrigeration until being unsealed.
Why is it recommendable to consume pasteurised
and ultra-pasteurised milk
Boiling doesn’t
destroy all germs form in the pure milk, but destroys most nutrients in
it. Pure milk can contain dangerous germs for our health.
Nobody can
guarantee an appropriate hygiene in the production and distribution of pure milk
in markets or in the environment.
1) It
doesn’t need to be refrigerated up to 6 months, unless the box has been opened
2) UHT milk Singapore increases product shelf life - The product shelf life is longer
3) No loss of nutritional properties during its long validity period
2) UHT milk Singapore increases product shelf life - The product shelf life is longer
3) No loss of nutritional properties during its long validity period
4) Preserved taste and nutrition - It has been
pasteurized at a higher temperature to preserve taste and nutrition
5) Prevent products from contamination - Using UHT treatment prevents the
products from being contaminated by airborne micro-organisms
All these
advantages of UHT milk Singapore could lead to suspicious of presence of
preservatives in the milk. At this point, the answer comes from the
wonder-packaging, the aseptic Tetra Pak.
