The possibility of controlling the quality of salad products under conditions of a closed agrobiotechnical system with controlled conditions by processing with silicon-containing preparations was tested experimentally: a complex preparation of hydrothermal nanosilica with synthetic analogue of phytohormone auxin, crezacin, in relation to silica, similar to organosilicon component 1-chloromethyl in Russia plant growth - the Energia M preparation. The use of hydrothermal nanosilica with synthetic phytohormone crezacin makes it possible to purposefully change the chemical composition and obtain products of a given quality. The effect of nanosilica on product quality is complex multilateral: organoleptic properties of the product are improved, the content of residual amounts of nitrates and the toxic element of lead is reduced, the proportion of solids, the level of antioxidant activity and the accumulation of vitamin C are increased. The content in leaves significantly (up to 2-3 times) vitamins of group B. The shelf life of products is increased by reducing water loss (dehydration) during storage. A significant stimulating effect on the test cultures of Paramecium caudatum and Daphnia magna was revealed, which gives reason to assume a high level of food safety, as well as the effect of the appearance of new properties in the salad - a manifestation of biological activity that improves the living environment for biotesting objects, which manifested itself in an increase in their vital activity and productivity. The data obtained can be used for practical purposes for growing salad products with a controlled enriched chemical composition and increased nutritional and biological value.
