Description

One kind, which has, adjusts the active feta proteolysis peptide of bone-marrow-derived lymphocyte and its preparation Method
Technical field
The invention belongs to technical field of nourishment, and in particular to one kind, which has, adjusts the active feta egg of bone-marrow-derived lymphocyte White range of hydrolysed peptides and preparation method thereof.
Background technique
Bone-marrow-derived lymphocyte is the important regulatory factor of human immune system, its function includes stimulate the reaction, antigen presentation, Inflammatory factor and antibody are secreted, can also be both immunoreacted by way of humoral immunity by cellular immunity, is helped Body is helped to support the invasion of antipathogen.Moreover, B immunocyte is repaired after additionally aiding help body tissue wound, is wrapped Include bone split, skin ultrastructure etc..In addition, bone-marrow-derived lymphocyte can also promote nerve fiber below scar tissue and interior significantly The growth in portion, the body for repairing these have normal physiological function.In old man, child, in the special populations such as patient, due to The decline of body's immunity, therefore played an important role by the activity that meal supplement adjusts bone-marrow-derived lymphocyte to keeping fit.
Casein is the main component of albumen in dairy products, and 80-the 85% of gross protein is accounted in cow's milk, in goat milk Casein content is slightly lower, is 74-80%.Casein is noncrystalline, non-hygroscopic substance, and human body is after edible lactalbumin, effect It is very fast with starting, it can be eaten before and after body building, be rich in branched-chain amino acid, it can make albumen in flesh during movement It shuttles in meat, or allows its effect immediately, certainly because what is digested is very fast, will not be kept in body too long.It is another Aspect, since the dissolubility of casein is substantially less than lactalbumin, edible casein may cause indigestion reaction.Using micro- Biology or biological enzyme caseinhydrolysate in vitro, increasing its soluble and property easy to digest is a kind of side for increasing its nutritive value Method.
The method of currently used caseinhydrolysate mainly passes through trypsin hydrolysis method, hydrolysis by novo method or Acid protease hydrolysis method obtains bovine casein hydrolysate, and usually these are sought as protein/amino acid supplements Support product development.But since method for hydrolysis is excessively single, obtained cow's milk hydrolysate composition is too complicated, therefore causes product Adjusting bone-marrow-derived lymphocyte immunocompetence function value is not high, and some even has side effect.Sheep cream is differed markedly from as a kind of composition The casein of cow's milk there is no the application to the exploitation of feta proteolysis product, also available without corresponding functional product, because This optimizes enzymatic hydrolysis process by the feta albumen of selection high quality, and the efficient adjusting bone-marrow-derived lymphocyte purified is active Small-molecular peptides have broad application prospects.
