БЕЗВІДХОДНА ТЕХНОЛОГІЯ ПЕРЕРОБКИ ДИКОРОСЛОЇ СИРОВИНИ

The article proposes waste-free technology of processing wild plant raw materials of Hippophae rhamnoides., Viburnum opulus, Sambucus nigra into powders. Methods. To determine the physicochemical parameters, standard research methods were used. The mass fraction of moisture was determined by drying to constant weight. The mass fraction of total sugar was determined by the permanganate method. Identification of the amino acid spectrum was carried out by ion-exchange column chromatography using the BIOTRONIK amino acid analyzer.Results. Moisture removal mode, which involves pre-dehydration for 1 hour by osmotic dehydration and subsequent drying in infrared dryers can reduce the process duration. The dried materials have final humidity, which allows grinding the dried material into powders ≤0.45 mm. Besides the reduction of the drying period, osmotic dehydration preserves the taste and aromatic properties of derivatives of processed wild berries and their natural color, which makes it possible to use powders as natural food additives in various sectors of the food industry. The proposed mode of heat treatment allows reducing energy consumption for the process and reducing the drying time to 2-2.5 hours. Conclusions. Analysis of the amino acid composition of powders made from derivatives of wild berries showed that they have high biological value and can be used to make functional food products.
