Ensuring the quality of confectionery products and controlling factors affecting changes in organoleptic characteristics during storage requires studying processes that affect lipase activity, one of which is the process of moisture migration. Lipase activity, the rate of the moisture transfer process, and the change in microbiota in various parts of the model samples of raw gingerbread with fruit filling, glazed with confectionery glaze based on lauric type fats, packed in a polypropylene film 40 ?m thick in an average layer-by-layer sample were studied: top layer with glaze, filling, baked semi-finished product. Studies have shown a correlation between analytical results and organoleptic evaluation. During storage during moisture transfer, moisture migrates from the filling to the baked semi-finished product and then to the upper layer with glaze, while in all layers the mass fraction of moisture stably remains above 5%, which is higher than the value at which lipase activity is maintained. The moisture transfer rate in the top layer was 1.12, in the baked semi-finished product – 1.34 and in the filling – 7.03 g/m2·s (· 10-4). Water activity decreased, but did not reach a threshold value of 0.6 after 12 weeks of storage. At the same time, at 6-8 weeks of storage, there is an increase in the activity of water in the baked semi-finished product, which indicates the release of free moisture. Organoleptic analysis revealed a “soapy” taste, starting from the 8th week of storage, which correlates with an increase in water activity. Microbiological studies showed a significant increase in the content of QMAFAnM from 8 weeks of storage, mold growth up to 410 CFU/g was observed at 10 weeks of storage. Studies have shown a correlation of lipase activity with moisture transfer processes and microbiota growth, which requires more stringent quality control of raw materials and storage conditions to prevent lipolytic damage to flour confectionery products glazed with confectionery glaze based on lauric type fats.

The problem of adequate and wholesome food is one of the most discussed in the world in the conditions of the deteriorating environmental situation, which entails a decrease in the level of health of the population. Significantly increases the need for vitamins, macro - and micronutrients, as in the most important protective factor. Marmalade has a number of advantages over other confectionery products: low energy value, the ability to bind and excrete toxins and salts of heavy metals, a relatively low price. The article presents the results of research work on the development of formulations of marmalade products based on vegetable puree of pumpkin, carrot and beet. The assessment of organoleptic, physico-chemical and rheological properties of raw materials. It was found that when making mashed potatoes from pumpkins, carrots and beets, it is necessary to ensure the introduction of a larger amount of gelatinizer in the preparation of jelly shaped marmalade to obtain products with a good gelatinous consistency. Defined organoleptic and physical-chemical indicators of quality and microelement composition of the finished products. It was found that the use of vegetable based puree, carrots, pumpkins or beets significantly increases the content of macronutrients in jelly marmalade (up to 9.5 times). Thus, the actual task of finding and introducing into production confectionery products containing in their composition non-traditional types of raw materials of vegetable origin, possessing high food and biological value and the ability to improve the consumer properties of the finished product.
