Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the traditionally prepared flaxseed oil has deep oil color, high acid value and peroxide value, large loss of α-linolenic acid, and high residual oil of pressed cake in the prior art. Problem, the present invention removes impurities by soaking flax seeds in lye, then mixes them with enzymes for enzymatic hydrolysis, destroys the integrity of flax seeds cells, then mixes them with solvents, adds additives, and performs steam explosion to make flax seeds The seed cells are completely broken, so that the oil flows out, and then squeezed, centrifuged, and bentonite removes impurities and decolorizes, so as to obtain edible oil with low acid value and peroxide value and high content of α-linolenic acid

Abstract

The invention relates to a method for preparing edible oil by using benne seeds, and belongs to the technical field of vegetable oils. According to the invention, to solve the problems of deep oil color and luster, high acid value and peroxide value and bigger alpha-linolenic acid loss of the traditionally prepared benne seed oil at present, and higher residual oil of pressed cakes in the prior art, the method comprises the following steps: soaking the benne seeds in an alkali liquor and removing impurities, then mixing the benne seeds with enzyme to carry out enzymolysis, destroying the integrity of benne seed cells, later, mixing the benne seeds with solvents and adding additives, and carrying out steam explosion, thereby completely breaking the benne seed cells to facilitate the outflow of oil, and squeezing, and carrying out centrifugal separation, impurity removing and decolorization on bentonite, thus obtaining the edible oil with lower acid value and peroxide value and high alpha-linolenic acid content.

Description

technical field [0001] The invention relates to a method for preparing edible oil from flax seeds, which belongs to the technical field of vegetable oil. Background technique [0002] The α-linolenic acid contained in flax oil is octadecatrienoic acid, which is the parent body of omega-3 series of highly unsaturated fatty acids, and is the most ideal resource to supplement the lack of omega-3 series of unsaturated fatty acids in the human body. In 1990, the International Symposium on "Omega-3 Series Unsaturated Fatty Acids and Health" held by the World Health Organization and the United Nations Food and Agriculture Organization solemnly stated: "In view of the clear evidence that omega-3 series oils are indispensable in human health The role of scientists recommend that all baby food and adult food should contain omega-3 series fatty acids". α-linolenic acid is the basic substance that constitutes human cells. It is indispensable to the human body. The human body cannot syn...
