There is soya milk and there is soya milk. Unsweetened carton milk, sweetened carton milk, powdered milk and then homemade unsweetened soya milk and finally homemade sweetened soya milk.
There are a number of considerations to be made when considering what is a good soy milk and what is undesirable. One of the biggest GMO crops in the world are soy or soya beans and South Africa is no exception and so first on the list would be whether the soya beans that the milk is made from are GMO free. If the packet or carton does not say say you can safely assume that the milk is manufactured with GMO soya beans. Remember when making homemade soya milk you need to be sure that the beans that you are using are also GMO free. Of course it would just be best to grow your own and then you can be absolutely sure that they are GMO Free AND organic.
The next on the list is the amount of sugar in the milk. Sugar is included under a variety of names: listed as maltodextrin, fructose, corn syrup solids or dextrose.
Maltodextrin, although not a sugar has a glycemic index of 130 which is double that of sugar and to top it all, it is often manufactured from corn. Corn is the next big GMO crop, so the question is whether the maltodextrin (not good in itself) is GMO.
In one powdered soya milk I found the E number 524 as an ingredient. For those that might not know, 524, a strong alkaline compound, Sodium Hydroxide, aka lye or caustic soda used for making soap. The Canadian Centre for Occupational Health and Safety says: “Ingestion: Can burn the lips, tongue, throat and stomach. Symptoms may include nausea, vomiting, stomach cramps and diarrhea. Can cause death.” Ok so what is this doing in Soya Milk? Guess the quantities must be low enough not to have this effect??
Woolworths sells a unsweetened certified organic soya milk that contains only water and soya beans at a price comparative to other supermarket soya milks that have numerous other ingredients in them.
