Comparative assessment of apple fruit storability during storage in different modes of the cooled medium

Abstract

The article presents the research results of the effect of post-harvest treatment with Phytomag preparation of fruits of 21 apple tree varieties of domestic and foreign breeding on their storability and quality. The purpose of the research is to determine the effectiveness of the combined effect of such technological techniques as post-harvest fruit treatment with Phytomag preparation and their storage in conventional (CGD) and regulated (RGD) gas dynamics on the formation of quality and storability of apples grown in the Crimea. The data obtained showed that the treatment of fruits with an ethylene inhibitor Phytomag during storage in conventional and regulated gas dynamics reduces losses, depending on the variety, by 1.5-1.8 times. It is established that the processed fruits retain their original marketable appearance, have high quality components during the entire storage period and after opening the refrigerating chambers, selling the fruits and bringing them to the consumer. It is proved that in the conditions of the Crimea such varieties as Tavria, Krymskoye Zimnee, Krymskoye, Orion, Kimmeria, Brebern, Fuji, Idared, Pink Lady can be successfully stored in a conventional gas dynamic with post-harvest treatment with preparation inhibiting ethylene synthesis. The advantage of storage in regulated gas dynamic was shown by the varieties Aromat Kryma, Predgornoye, Golden Delicious, Crispin, Granny Smith, Glouster, Gala, Jonagold.

Microbiological and bacterial diseases of apple fruits during storage

“…The key factors determining the vital activity of fruits in the period after harvesting are temperature (Ɍ°ɋ), as well as the content of oxygen (O2) and carbon dioxide (CO2) and relative humidity (%) in the storage atmosphere [8,11,12,13,14,15,16,17]. According to the results of studies by domestic and foreign authors, the main cause of diseases development and a decrease in product quality is the excessive accumulation of ethylene (C2H4) inside fruits and the environment.…”
