Annotation
In this article, the physico-chemical properties of apricot, peach and bitter almond seeds were studied, based on which research was conducted on the extraction of amygdalin oil. Oils were obtained by extracting the core of the grains, and these were analyzed and their physico-chemical properties were determined. Also, the process of extracting oil from peach, apricot and bitter almond seeds by pressing method was studied, the physico-chemical properties of apricot, peach and bitter almond seeds were studied, and research was conducted on the extraction of amygdalin oil based on them. Apricot, peach and bitter almond oils have been proven to contain more than 88.0% of unsaturated fatty acids, and more than 20% of unsaturated fatty acids are highly unsaturated essential fatty acids - linoleic and linolenic acids.
