Technical Field
The invention belongs to the technical field of food processing, and particularly relates to a detoxification method of linseed kernels.
Background
Flax, also known as flax, is one of ten oil crops in the world and is widely distributed in many countries and regions. Flaxseed contains various functional active ingredients, such as alpha-linolenic acid, omega-3 unsaturated fatty acid, flax diglycoside, flavonoid, lignan and the like, flaxseed oil is vegetable oil with the highest omega-3 content in land, is called liquid gold due to the importance to the body, and can supplement the brain by eating walnuts, and the walnuts are rich in omega-3 and metabolites thereof. In addition, the linseed kernel also has certain efficacies of resisting cancer, viruses and thrombus, reducing blood fat, improving skin and arthritis and the like, so the linseed kernel is an excellent health-care food. However, the kernels of the linseed contains a toxic substance, namely cyanogenic glucoside, the cyanogenic glucoside does not have toxicity, but can react with coexisting beta-glucosidase to generate alpha-cyanhydrin under a proper condition, the alpha-cyanhydrin is extremely unstable and is naturally decomposed into corresponding ketone, aldehyde compounds and hydrogen cyanide, and the hydrogen cyanide is a highly toxic gas, which is the principle of edible fresh linseed poisoning.
The existing flaxseed detoxification method comprises a water boiling method (removal rate: 96.81%), a microwave heating method (removal rate: 89.64%), a solvent method (removal rate: 84.42%) and the like. For example, in the literature, "progress in research on cyanogenic glycosides of flax seeds" (J "), a method for removing cyanogenic glycosides is disclosed, in which a boiling process is employed, sufficient water is used to make glycosidase exert sufficient efficacy, and finally cyanogenic glycosides are converted into hydrogen cyanide and released, but the way of water entering flax seed kernels in the process is natural penetration, which has the disadvantages of slow reaction and incomplete reaction, and on the other hand, nutritional components in flax seed kernels are easily lost by boiling at high temperature. In addition, the microwave heating method has low detoxification efficiency, and the solvent method may generate harmful solvent residues.
