soya milk preservative

[sammy akpor]

Hi,
I want to know there is any safe preservative for soya milk?
And what is it?

[Rob]

As far as I know it is not possible to chemically preserve soya milk. Common preservatives such as sodium benzoaat and potassium sorbate only work in foods with low pH, such as fruit drinks and sour salads. Many producers claim that their soya milk is preservative free, but this claim does not make sense since preservatives are never added to lengthen the shelf-life of soya milk.

i use sodium benzoate only to find out that it changed the color and taste of soya... do you have other option?

You cannot chemically preserve soy milk because it has a neutral pH. Preservatives such as benzoic acid of sorbic acid only work well in acid products, as explained in previous post. Benzoic acid also has a typical chemical taste that you can detect in levels as low as 50 ppm. The only possible way to store soy milk for a long time at room temperature is to treat it with UHT heat treatment and fill aseptically.

Ultra-High Temperature (UHT) treatment is the sterilization of food by heating it for a few seconds only at a temperature exceeding 135°C, which is required to kill spores. This is something you cannot do at home, you need special expensive UHT machinery.

Hi guys all i know to some commercial soy milk is made completely sterile by heating at very high temperature during short time (for example 30 sec at 135?C). This you can not achieve in your kitchen, even boiling will not kill all bacteria. Your utensils may also contain some bacteria well its depends anyway for you how you manage things into your house etc by the way this is the first time i been here so i just reading some of your comment guys and nice to meet all of you also i hope my opinion helps its just for hygiene:)

Thanks and god bless

Kindly Regards
