The influence of cooling technology on the content of biologically active substances in vegetables at keeping in a vegetable storage

The objective of the study was the effect of cooling technology on the mode of stabilization of microclimatic conditions on the content of biologically active substances in beets and carrots during bulk storage during the seasons (autumn, winter, spring, summer) in a buried storage facility with natural supply and exhaust ventilation. The research objectives were microclimatic conditions (temperature regime, air humidity) of vegetable storage in different seasons in the south of Krasnoyarsk Region; the determination and analysis of biologically active substances in beet and carrot root crops with identification of their seasonal differences. The objects of the research were beet roots (table medium-early variety Bordeaux 237) and carrots (table root, variety Chantenay 2461). The storage of beetroot varieties Bordeaux 237 and carrots, seeded variety Chantenet 2461, took place in a vegetable storehouse located in the village of Solontsy, Krasnoyarsk Region. Cooling technology during vegetable products storage allows long-term preservation of high quality raw materials, taking into account the assessment of the condition of vegetables. When using cooling technology, in vegetable stores of the buried type with natural supply and exhaust ventilation, there are storage stages: preparatory, preliminary and main. Biologically active substances (sugars, starch, organic acids, ascorbic acid) preserve optimal content while observing the storage stages and maintaining microclimatic conditions (temperature regime and relative humidity) in different seasons of the year. Optimal content of biologically active substances in the diet necessary for nutrition is maintained during autumn, winter and spring (270-280 days).
