Description

A kind of fungus and polysaccharide and probiotic bacteria composite functional food
Technical field:
The invention belongs to nutritional health food field, be specifically related to a kind of fungus and polysaccharide and probiotic bacteria complex function Property food.
Background technology:
Ganoderma, is considered as the magical treasure of strengthening by means of tonics, strengthening the body resistance by successive dynasties medicine man.Main containing aminoacid, many Peptide, protein, fungal lysozyme (fungal lysozyme), and saccharide (reducing sugar and polysaccharide), Ergota Sterol, triterpenes, coumarin glycoside, volatile oil, stearic acid, benzoic acid, alkaloid, vitamin B2 and C Deng;Spore is also containing mannitol, trehalose (trehalose).Through a large amount of clinical researches, Ganoderma to neurasthenia, Hyperlipemia, angina pectoris, arrhythmia, Keshan disease, plateau discomfort disease, hepatitis, hemorrhagic fever, disappear Change the curative effect of the degree of having nothing in common with each other such as bad, tracheitis.It should be noted that only by with Ganoderma dietetic therapy this The method of kind can not play obvious prevention effect, it is proposed that the available prescription such as Semen Cassiae, black oolong is certainly crow soup tea This classical Chinese medicine prescription tea, can play good prevention effect to diseases such as hyperlipidemia.Pharmacological research proves, Ganoderma has many biological activitys.
Tremella (Tremella fuciformisBerk), is commonly called as Tremella, obtains tremella polysaccharide in sporophore (Tremellam) it is a kind of acid heteroglycan, has and improve body's immunity and promote the effect of leukocyte.Can Significantly improving the phagocytic function of laboratory animal reticuloendothelial cell, have promotion nonspecific immunity effect, raising is exempted from Epidemic disease globulin, the level of total complement of serum.Can prevent and treat and be caused with antitumor drug (such as CTX) by radiation Bone marrow depression, also can promote the synthesis of liver internal protein.
Fungus polysaccharide also known as polysaccharide, is the class biomacromolecule generally existed in biologic artifact, not only joins With the composition of histiocyte skeleton, and it is the important composition composition of multiple endogenous bioactive molecule.Have one The effect of fixed regulation body's immunity, its effect is multipath, too many levels, Mutiple Targets, as promoted to exempt from Epidemic disease cell proliferation and differentiation, secrete various lymphokine, regulation Neuroendocrine-immunoregulatory network (NIM) Balance etc..
Fungus polysaccharide has extremely strong repair to cell.Take fungus polysaccharide health food, can supplement in time The materials such as the polysaccharide lacked in intercellular substance, make impaired cell be repaired timely, reach to keep cell to be good for Health, extend cell survival thus realize the purpose of health.Shanghai Medical Univ Li Rui etc. test discovery, Fungus polysaccharide can significantly improve mobility and the closed stratum of cell membrane, after old and feeble cell is cultivated with fungus polysaccharide, Closed stratum raising 11%, mobility raising 32%, cell membrane fluidity, the raising of closure, show cell Physiological function is improved.
Modern science and technology shows, fungus polysaccharide is most important active ingredient contained in edible fungi.Be a kind of β- The polysaccharide of type, has pharmacologically active widely.Ganoderma, Cordyceps, Auricularia, Tremella, Lentinus Edodes, Hericium erinaceus (Bull. Ex Fr.) Pers., The edible fungi such as Pleurotus nebrodensis, Concretio silicea Bambusae seu schizostachyi, Coriolous Dersicolor (Fr.) Quel, coprinus comatus, Tricholoma matsutake (lto et lmai) Singer, Phellinus igniarius (L. ex Fr.) Quel., all contain fungus polysaccharide.
Chinese invention patent 201110407414.2 discloses a kind of mycotrophy liquid with health role, should Nutritional solution, with funguses such as Lentinus Edodes, Grifola frondosa, Hericium erinaceus (Bull. Ex Fr.) Pers., Coriolous Dersicolor (Fr.) Quel as primary raw material, is aided with oligomeric xylose, different wheat The nutrients such as bud ketose alcohol, taurine, lysine, vitamin E, xanthan gum and water process, and raw material is joined 5 science, synergism, there is raising body immunity and promote that body gastric mucosa injury repairs Double-function health care Effect.
Probiotic bacteria, is the active microorganism that a class is useful to host, is to be colonizated in human body intestinal canal, reproductive system, Definite health efficacy can be produced thus improve host's microecological balance, the active beneficial microbe of performance beneficial effect General name.It is widely used in biological engineering, industrial or agricultural, food safety and life and health field.
Regulation gastrointestinal function disorder is one of function of being widely known by the people most of probiotic bacteria, and in addition, probiotic bacteria also has Have and produce nutrient substance, the infection of opposing bacterial virus and the function of some disease of prophylactic treatment.The present invention will A kind of composite fungi amylose compositions being added with probiotic bacteria is provided, has fungus and the merit of polysaccharide raising immunity concurrently Energy and the health-care effect of probiotic bacteria, improve the current problem that health product effect is single, complex function is undesirable.
