Honey-Jam
Honey, the main ingredient of Jam was 60-70% invert sugar. (26-34% glucose, 38-41% fructose, 0.5-1.5% sucrose, 5-11% maltose).

Sauces
Sauces are minimally processed foods. Shelf life is also limited. As is known, some of them are low acid and are kept cooled (-2, + 4 ° C). In order to prolong the shelf life of this type of food, fluctuations in their temperatures are not allowed by thermal processes such as pasteurization and cooking. In addition, the oxidation hazard can be prevented to a great extent with the help of antioxidant substances added to sauces. The substances used in the preparation of sauces are mostly pasteurized.
