Abstract: . Biodegradable coatings made from naturally occurring substances can protect fruits and vegetables during storage. The purpose of this work was to study the effect of film-forming compositions based on solid mono- and diglycerides of fatty acids and ethyl alcohol on the weight loss and biochemical composition of Xantero F1 tomatoes (red degree of ripeness), Severin F1 cucumbers, Aral F1 courgettes and Baron beetroot. It was found that the treatment had a positive effect on the keeping quality of the research objects: in the case of tomatoes, the weight loss after 14 days of storage was 6.41-10.41 % versus 12.55 % in the control; in the case of cucumbers, after 14 days of storage, the losses amounted to 22.79-25.69 % versus 29.03% in the control; in the case of courgettes, after 14 days the weight loss was 6.54-7.49 % versus 9.74 % in the control; in the case of beetroot, after 6 days of storage, the losses amounted to 19.22-21.62 % versus 23.42 % in the control. It was found that ethyl alcohol is a more preferable component of film-forming compositions than isopropyl alcohol. In addition, a change in the biochemical composition of the research objects was also revealed as a result of the treatment: for example, tomato and cucumber samples with the least weight loss had higher levels of vitamin C, while coated cucumbers had higher levels of polyphenolic substances. The data obtained can be used to develop new methods for storing tomatoes, cucumbers, courgettes, and beetroot using biodegradable protective coatings. Keywords: tomatoes, cucumbers, courgettes, beetroot, bio-destructible coatings, storage, biochemical composition, weight loss Financing source: The research was carried out within the State Task of Ministry of Science and Higher Education of the Russian Federation for the FSBSI NCFSCHVW.
