Rezumat

Freezing, at least of vegetable products, no matter of what anatomic part we reffer to – root, stalk, leaf, flower, fruit or sead – induce manifested biochemical changes, including rH tissue modification. The farther is the value of native rH from a characteristic (compatible) value to the animal organism (about 26), the deeper are the rH changes after freezing. The changes obtained by freezing are: if the native rH is bellow 26, the product is oxidizing; in the opposite situation, the product is reducing as if the vegetable products as a whole would look to obtain an homeostazis (redox).
