Background
Fructus cannabis is a mulberry, cannabis, a medicine and a product, and has a history of eating for more than 3000 years in China. The nutritional structure and the content proportion of the fructus cannabis are reasonable, the content of fatty acid is 25-45%, unsaturated fatty acid accounts for more than 90%, linoleic acid accounts for 50-60% of the unsaturated fatty acid, linolenic acid accounts for 20-30%, the proportion of omega-6 and omega-3 is close to the optimal proportion of human body physiological metabolism, and the oil is regarded as high-quality oil; the protein content is 20-25%, 8 essential amino acids are contained, and compared with common vegetable protein such as soybean protein, the protein does not contain high-level enzyme inhibitor, so the digestibility is high; the carbohydrate accounts for 10-20%, and the fiber accounts for 10-15%; in addition, it also contains various minerals and polyphenol. At present, the fructus cannabis is mainly applied to grease development, the fructus cannabis oil contains rich unsaturated fatty acid (prostaglandin) and eicosanoids, and is beneficial to chronic diseases caused by the recovery of the immune system of a human body and adjuvant therapy; the product also contains about 3.5% of gamma-linolenic acid, which can repair damaged nerve cells, treat insomnia caused by neurasthenia, prevent the loss of cerebral neurons, prevent and treat nerve diseases, has good antioxidant effect and health care effect, can improve the quality of skin fat, treat eczema, and prevent constipation, hyperlipidemia, hypertension and other diseases.
The cake produced after pressing oil from hemp seeds is called hemp seed meal, which is mainly used as industrial feed. With the intensive research, the fructus cannabis meal also contains about 30% of protein, is mostly edestin and albumin, and has higher amino acid nutrition and digestibility compared with the soybean protein isolate. Clinical tests prove that the hemp seed protein has the effects of improving anoxia resistance, improving tolerance, improving anemia, regulating immunity and the like. The hydrolysate of fructus Cannabis protein has good antioxidant, antifatigue and immunoregulatory effects.
At present, fermented milk products in the market are mainly single or compound fruit fermented milk, the innovation point is single, most fermented milk products are added with food additives, and the fermented milk products are not beneficial to human health. With the change of consumption, more and more consumers can not only pay attention to the sensory enjoyment but also pay attention to the nutritional function characteristics when selecting products.
