I’m amazed at the various interpretations of ‘raw food’.
Raw means uncooked, unprocessed, in its natural form with live, active enzymes and other micronutrients.
Is Cold Food Raw?
Raw doesn’t necessarily mean cold and cold definitely doesn’t mean raw! For example, ham is not raw. It is a slice of a pig’s bottom which has been cooked, chemically preserved and sliced. As it is usually served cold, it is mistakenly thought to be raw, but it most certainly is not!
Tinned foods are not raw either. If you locked raw food in an enclosed space, it would start to digest itself, producing gas, so the container would bulge, then possibly pop open, releasing a vile smell!
The canning industry was one of the first to discover enzymes, as they realized they had to destroy the enzyme activity in order to preserve the food. So they heat the food in the can / tin to kill the enzymes and any bugs (they hope!) giving the food a long shelf life. The food inside is of course totally lifeless and frankly not worth eating.
Pasteurization is another enzyme-killing process to preserve foods, usually milk and juices. The liquid is heated above enzyme killing temperature (which is around 42 degrees centigrade although they heat it to about 72 degrees centigrade) but below boiling to preserve flavour.
How Can We Preserve Raw Food?
It is possible to preserve the live enzymes and other micro-nutrients in raw foods by either freezing or carefully drying them. The drying process must stay below 42 degrees centigrade. With human food, various fruits and vegetables can be sliced and dried in dehydrators to form ‘leathers’ or crispy leaves or even crisps.
Powdered supplements are available that have been very carefully dried too, like Juice Plus for humans and Pet Plus for Dogs and Cats. The process is more tricky because once the food has been broken down into fine particles (i.e. juice) ready for drying into a powder, it is vulnerable to oxidation, another deterioration. So the drying process is completed in an anaerobic environment (i.e. with no oxygen) for both Juice Plus and Pet Plus. The care and attention to detail in the production of these two exceptional, world class, whole food nutritional supplements ensures they are the very best money can buy!
