QUALITY AND FATTY ACID COMPOSITION OF FILBERT NUT OIL

Abstract

This article is devoted to the research o f filbert nut oil quality (Corylus domestica Kosenko et Opalko) and its fatty-acid composition.It was clarified that oil content in the kernel o f filbert nut have been varied subject to the variety. Such varieties as Hrandiznyy, Funduk-85 and Urozhainyy-80 had the biggest index, whereas Lozivskyy Urozhainyy had the lowest one. The index o f oil content varied against weather conditions during the period o f research, and the revealed differences between the varieties remained. High oil content o f filbert nuts is the perspective source o f herbal remedy relative to the potential commercial value.Biological value o f oils is determined by the content o f unsaturated fatty-acids, whereas the index 16% o f linoleic acid which we got during our researches in the mixture o f filbert oils testified the prospect o f usage the filbert nut kernels as the raw material for oil industry at all, so as for improvement o f liposome stability which we got from vegetable phospholipids.Unsaturated fatty-acids predominated in the content o f all fatty-acids o f general lipids o f all investigated filbert varieties.Increased content o f unsaturated fatty-acids testify to the more wide adaptive possibilities. The ratio o f unsaturated and saturated fatty-acids o f filbert nuts is nearly 10, and it is the best index between the industrial oils.
