By base(ROO)And hydroxy radical(-OH)With very strong oxidation.Under normal physiological conditions, internal antioxidase and non-
The enzyme factor can effectively remove free radical, so as to maintain the poised state of free radical.But in pathological conditions, can be rapid
The peroxidating of lipid is caused to cause the damage of cell membrane, DNA and protein active, so as to cause a variety of human diseases related.Therefore,
It is an important channel for defending organism disease to occur to the removing of interior free yl.Because the antioxidant majority of synthesis is present
Potential safety hazard, therefore, screening is efficient, low toxicity antioxidant turns into the new trend of biology, medical science and food scientific research.
There are some researches show the active peptide from multiple protein all has antioxidation activity, and enzyme solution is that biology is obtained from albumen
One of effective ways of active peptide, have been widely used as a kind of method for improving protein active function and nutritive value.
Protein among diet is mainly absorbed in enteron aisle in the form of polypeptide and amino acid, and polypeptide is in body antioxidation process
Play an important role.In recent years to oceanic biological active peptides, the research of particularly antioxidation active peptides has made great progress.
But marine active peptide not yet forms industrial scale, therefore, the enzyme engineering technology of land active peptide exploitation is used for reference, with marine organisms egg
Bai Ziyuan is raw material, passes through the comprehensive study to techniques such as enzymolysis, preparations, you can develop land protein sources and chemical synthesis institute
Series natural, the biologically active peptide efficiently, novel that can not be produced.
Squid is ocean cephalopod important in the world, and its growth cycle is short, fertility is strong and resource recovery is fast
Speed, is a kind of sustainable marine fishery resources.In recent years, with the development of domestic and international deep sea fishing technology, squid has turned into
The main marine fishing of China and aquatic products processing kind.At present, the annual squid processing capacity of China is up to 40 ~ 500,000 t, occupies the world
One, processing variety is mainly North Pacific squid, Argentinian squid and Peru squid.Squid is because of the fine and smooth nutrition of its meat, wind
Delicious, a variety of necessary amino acid with high protein and low fat, rich in needed by human body, enjoys consumers.In squid
Typically its trunk is processed in process, the accessory substances, wherein gonad such as 50% or so internal organ is produced(Spawn tangled gland,
Spermary, ovary etc.)The 20% of internal organ is accounted for, the accessory substance such as these internal organ is usually processed into feed, is used as the bait of fish;Squid liver
Dirty be extracted after Squid Oil is buried;Obtained from squid spawn tangled gland generally only to make culinary art edible, biological added value it is low and not and
When processing can certain pollution be caused to environment.Extraction on squid spawn tangled gland enzymolysis polypeptide has not yet to see report.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of North Pacific's squid spawn tangled gland with anti-oxidation efficacy
