Embodiment 1

[0026] Firstly, the corn protein starch is prepared porously, after the corn protein starch is slurried and fermented, filtered, washed, dried and pulverized to make the corn protein porous starch.

[0027] Secondly, corn protein starch was dissolved in 80% ethanol solution to prepare 10% prolamin zein liquid, which was used as embedding agent for α-linolenic acid microcapsules.

[0028] Use cold-pressed linseed oil with α-linolenic acid content of not less than 35-42%, add the prepared corn protein porous starch to the cold-pressed linseed oil, make the corn protein porous starch fully adsorb the cold-pressed linseed oil to saturation, and make adsorption Corn protein porous starch core material of cold pressed linseed oil.

[0029] Add 50Kg of zein porous starch core material adsorbed with cold-pressed linseed oil into the rotary coating pan and rotate and stir, and 80Kg of embedding agent 10% alcohol-soluble zein liquid is evenly sprayed into the rotary coating pan for 4 ti...

Embodiment 2

[0031] The corn protein starch is slurried and fermented, filtered, washed, dried and crushed to prepare the corn protein porous starch. Adding it into the cold-pressed linseed oil, making the corn protein porous starch fully absorb the cold-pressed linseed oil to saturation, and making the corn protein porous starch core material which absorbs the cold-pressed linseed oil.

[0032] Take 8Kg of zein starch and 2Kg of oleic acid and dissolve them in 100Kg of 75% ethanol solution to prepare alcohol-soluble zein solution, which is used as an embedding agent for α-linolenic acid microcapsules.

[0033] Take 50Kg of corn protein porous starch core material adsorbed with cold-pressed linseed oil and add it to the rotary coating pan for rotation and stirring. The above-mentioned embedding agent is evenly sprayed into the rotary coating pan for coating in 4 times.

[0034] While continuing to rotate and stir, pass hot air at 70° C. for drying to obtain α-linolenic acid microcapsules w...

Abstract

A production method of an ALPHA-linolenic acid microcapsule comprises the steps of: mixing cold pressed linseed oil and corn protein porous starch used as a carrier, coating with alcohol-dissolved corn protein liquid, and producing ALPHA-linolenic acid microcapsule with a rotary embedding method. The used corn protein porous starch and alcohol-dissolved corn protein are both natural food raw materials with good safety and stable properties, which can effectively powder liquid oil and fat, so as to prevent the oil and fat contacting with air and delay the oxidative deterioration of the unsaturated fatty acids in the linseed oil, and can block the unpleasant odor sent out from the linseed oil. The inventive production method is simple; and the obtained ALPHA-linolenic acid microcapsule can be conveniently stored and transported, and can be widely used in foods or nutritional health products.

Description

technical field [0001] The invention relates to the production technology of α-linolenic acid, in particular to a production method of α-linolenic acid microcapsules. Background technique [0002] Flax is an annual herb of the Linaceae family, and is an ancient bast fiber crop and oil crop. Flax originated from the Mediterranean coast of the Near East and is distributed all over the world. It is most planted in the arid and semi-arid alpine regions of Northwest my country and North China, where the quality is the best. [0003] Flaxseed belongs to the seeds of flax for oil, and the oil content of flaxseed for oil is 35-42%. Flaxseed oil is rich in unsaturated fatty acids and is currently the omega-3 plant with the largest yield and highest content. [0004] At present, in nutrition research, the most frontier field widely concerned by international nutrition experts is the applied research on omega-3 series unsaturated fatty acids. This is because omega-3 series unsaturat...
