Description
Technical field:
The invention belongs to food technology manufacture field, be specifically related to a kind of new method of linseed deep processing.
Background technology:
Flax is the natural plant fibre that the mankind use the earliest, has had more than 5,000 year in human history, hasHigher nutritive value and certain pharmacology are worth. Meanwhile, flax or oil crops, linseed oil is not containing volumeSaturated fatty acid, therefore be used for preventing hyperlipemia and atherosclerotic. In linseed, contain 45% left and rightLinseed oil, the flax protein of 20% left and right, the flax lignan of 0.9%～2% left and right, the meals of 10% left and rightFiber, the flaxseed gum of 10% left and right. Wherein, in linseed oil, contain 45%～60% alpha-linolenic acid, AsiaFiber crops acid has height vision protection, highly increases intelligence, suppresses the effect such as allergic reaction, antiinflammatory action. ThisA little active ingredient waits pharmacological action to have great help to supplementing with anticancer of human nutrition.
Flax lignan, calls off again the different larch phenol diglucoside of ring. This is quite similar with human body estrogenPhytoestrogen. Flax lignan is mainly present in linseed, generally accounts for 0.9%～2% of seed weight,Higher 100～800 times than other known 66 kinds of food containing lignan, its content depends on Flax Varieties, weatherAnd ecological condition. Lignan can by with the competitive binding of ERs, affect the new of steroid sex hormoneOld metabolism, thus the tumor growth that estrogen causes can be suppressed. Flax lignan is to estrogen-dependent diseasesBreast cancer, prostate cancer, menstrual period syndrome, osteoporosis have prevention effect. It can hinder the one-tenth of tumorLong, dephlogistication symptom, improves the anomaly of blood fat, to reduce cardiopathic ill probability, and helpsBalance hormone content. In addition, clinical studies show flax lignan is to diabetes, stomach and intestine tumor, kidneyPopular name for, the effect that non-oxidizability is useful.
The research of technique of extracting about flax lignan: the people such as Yang Hongzhi are 70% at concentration of alcohol, temperature is60 DEG C, pressure are that 30MPa, time are to utilize supercritical carbon dioxide to extract lignan under 30min condition,Its highest yield is 7.615mg/g.
