Linseed oil microcapsule powder and its prepn

Abstract

The present invention is linseed oil microcapsule powder and its preparation, and features that modified polysaccharide, sodium octyl alkenyl succinate starch, is used as capsule wall material for forming microcapsule in preparing linseed oil microcapsule powder. The preparation process includes adding linseed oil into the solution of sodium octyl alkenyl succinate starch, stirring to form homogeneous emulsion, high pressure homogenizing to obtain linseed oil emulsion of granularity smaller than 1000 nm, and final spray drying or freeze drying to obtain white linseed oil microcapsule powder with high stability and high flowability. The linseed oil microcapsule powder has high linseed oil activity, high stability and high bioavailability, and may be applied in food and health product.

Description

technical field

[0001] The invention relates to the field of food and health products, in particular to linseed oil microcapsule powder and a preparation method thereof. Background technique

[0002] Flax oil is mainly extracted from flax, which is mainly distributed in North China and Northwest China. The linseed oil obtained by pressing flax mainly contains unsaturated fatty acids such as linolenic acid, and contains more than 50% of α-linolenic acid.

[0003] Human daily essential fatty acids include saturated fatty acids and monovalent unsaturated fatty acids, linoleic acid (omega-6 series) and α-linolenic acid series (omega-3 series), the human body can synthesize saturated fatty acids and monovalent unsaturated fatty acids , but cannot synthesize linoleic acid and α-linolenic acid, and can only be ingested from food. α-linolenic acid has the functions of inhibiting allergic reactions and anti-inflammation, protecting eyesight, enhancing intelligence, improving memory,...
