THE INFLUENCE OF THE DURATION OF LED LIGHTING ON THE BIOCHEMICAL COMPOSITION OF THE PEAS MICROGREENS

The results of a comparative study the effect duration LED lighting are presented (8, 10, 12, 14, 16 hour) on 13 characteristics biochemical composition vegetable peas microgreens (Pavlusha variety) - content dry, tannic and pectin substances, free organic, ascorbic hydroxycinnamic acids, soluble sugars, total protein albumins, main groups bioflavonoids indicator sugar acid index. dry matter in studied samples was 9.3-11.8 %, acids mass 4.35-8.46 359.8-487.8 mg/100 g 1465.1-1956.0 g, respectively. sugars from 8.8 to 13.2 % with significant variant differences index, which varied range 1.04-3.03. At same time, parameters accumulation substances were 3.884.54 tannins 1.23-1.92 %. almost complete absence anthocyanin pigments pea found, flavonols 1711.7-2189.2 catechins 376.7-483.0 g. high proteins their valuable part (albumins), mg/g weight ranges 412.3-443.4 8.38-18.0, found microgreens. considerable width variation micro-green testified dependence lighting, ambiguous. least changes relative control (12 hours duration) detected at 10 14 illumination duration, while greatest 8 especially duration. highest integral level nutritional vitamin value products according totality is set illumination, minimum hours.
