Abstract

Chemical composition of sea-buckthorn and highbush blueberry fruits determines their value while using them fresh or processed. Berries have distinctive characteristics depending on a variety, soil and climatic conditions and growing techniques. The object of the researches have been Sea-buckthorn (Hippophae L.) of three varieties (Podarok sadu, Trofimovskaya, Botanicheskaya) and Highbush Blueberry (Vaccinium corymbosum L.) of five varieties (Duke, Bluetta, Bluecrop, Northland, Coville) grown in the Republic of Belarus. Sea-buckthorn and Highbush Blueberry fruits chemical composition has been studied during a three-year cycle of monitoring using standard methods and in accordance with technical legal acts of the Republic of Belarus. Solid content (13,0-15,3%), sugar content (4,00-4,80%), organic acids (1,10-2,05%), nitrogen substances content (0,29-0,46%), lipids (3,6-6,2%), pectin content (0,40-0,50%), fiber (3,20-4,90%), minerals, vitamin С (44,7-78,7 мг/100г), β-carotene (4,4-13,2 мг/100г) have been studied in Sea-buckthorn (Hippophae L.). Solid content (12,2-15,1%), sugar content (2,73-3,96%), organic acids (0,59-0,95%), pectin content (0,57-0,97%), fiber (1,20-1,68%), bioflavonoids (276-368 мг/100 г), bioflavonoids complex fractional composition (anthocyanins, leucoanthocyanins, catechines, flavonols), vitamin С (60,5-72,2 мг/100 г) and mineral content have been studied in Highbush Blueberry (Vaccinium corymbosum L.). Exogenous contaminants content (arsenic, heavy metals), hygienical safety indexes, caesium 137 radionuclides content have been investigated in the fruits. Specific varieties characterictics of Sea-buckthorn (Hippophae L.) and Highbush Blueberry (Vaccinium corymbosum L.) fruit chemical composition have been determined. The studied fruit is fully safe and can be recommended to be used both fresh and processed.
