Abstract | Full Text: This article presents the results of studies of the properties of marmalade with natural plant cryoadditives during storage for 3 months (90 days). To improve the organoleptic characteristics and antioxidant properties of marmalade, plant additives of cryogenic origin were used, namely cryopastes from quince, apple, carrot, pumpkin, grapes, and cryopowders from rose hips, sea buckthorn, and grapes. It is shown that the use of plant cryoadditives makes it possible to increase the biological value and antioxidant properties of new types of marmalade. For new types of marmalade with cryoadditives, during its shelf life, these properties have not been studied earlier. However, it should be noted that such studies are necessary and relevant for solving the problem of preserving the quality indicators and antioxidant capacity of marmalade with cryoadditives. New kinds of marmalade have high organoleptic characteristics during the whole storage period. It is shown that the storage conditions of marmalade, according to current regulatory documentation, are suitable for new marmalade products, since the physico-chemical and microbiological indicators vary, but remain within acceptable limits. Thus, the moisture content decreases to almost 31%, the acidity rises by 12–16%, compared to freshly prepared samples. The content of reducing substances increases by 30–64%. It is determined that the value of the antioxidant capacity of all the samples developed is much higher – almost 2.3–8 times than the same figure for the control sample. After the storage period, the antioxidant capacity is reduced by 15–35%, but this data also significantly exceeds the antioxidant capacity of the control sample. Storage of marmalade with cryopastes and cryopowders for 90 days is possible, since all the basic physico-chemical, microbiological, and organoleptic indicators at the end of shelf life meet the requirements. Indicators of antioxidant capacity for them also remain at a fairly high level. New technologies of jelly-fruit marmalade with plant cryoadditives have been introduced at 4 enterprises. 2 utility model patents have been received, and regulatory documents have been developed and approved for the manufacture of new jelly products.
