INFLUENCE OF STORAGE CONDITIONS ON CHANGES IN SOME QUALITY INDICATORS OF APPLE TREE FRUITS

Abstract

The article presents the results of studies conducted on apple fruits of late varieties Idared, Golden Spur and Mantuanskoe. It was shown that as a result of the use of the film-forming preparation ,,Pelecol” in fruit tissues, due to a decrease in oxygen concentration and an increase in carbon dioxide, the consumption of sugars (sucrose and the sum of sugars) was reduced compared to the control. A more intense decomposition of sucrose was observed in fruits when stored under normal atmosphere conditions. The data obtained showed that at the end of storage, the sugar consumption of apple fruits of the Idared variety treated with a film-forming preparation at a concentration of 1,0% decreased to a greater extent compared to other varieties. Keywords: storage, apple fruits, sugar, Pelecol, film-forming coating. DOI: https://doi.org/10.59295/sum1(171)2024_20
