Description
Technical field
It is specifically a kind of that there is the tuna for suppressing cancer cell effect to extract the present invention relates to health products preparing technical field
Thing.
Background technology
It is well known that malignant tumour turns into the principal disease for threatening human health, it, which is treated, also turns into of concern
One of focus.Traditional chemotherapy and radiation also produces serious toxic side effect while treatment.The biological therapy of tumour be after
4th kind for the treatment of means of traditional remedies, current research is it has proven convenient that biological therapy is played more and more in the treatment of tumour
Big effect, and be expected to turn into the therapy for capturing tumour.
Polypeptide since earlier 1900s just attract attention, research finds that it is different from protein and is different from amino acid, has
There is medicine.Having arrived eighties of last century the nineties just has tremendous development, under the technological guidance of continuous renewal, polypeptide
Application is more and more wider, acts on also increasing, this has just strided forward our life, and the share occupied in we live is got over
Come bigger, polypeptide drug high-efficiency low-toxicity high specificity has the peculiar advantage for being different from other drugs, just constantly affects me
Life.It is the another quantum jump and developing direction of bioscience development and polypeptide has a high potential.
Naturally occurring Marine Bioactive Peptides due in organism content it is low, and extract difficult, it is difficult to realize a large amount of
Needed for production supply, chemical artificial synthetic polypeptide is costly.So, sight is more invested exploitation proteolysis production by people
Come in this approach of thing acquisition active peptides.Because environment and the terrestrial life that marine organisms survive are entirely different, such as high pressure, low
The extreme environment such as temperature, high temperature and high salt, in order to adapt to the marine biological environment that these are extreme, marine protein matter no matter amino
The composition or the sequence of amino acid of acid are all very different with terrestrial life albumen, meanwhile, marine protein resource without
By being all far longer than land protein resource in type and quantity, and do not developed well.Miscellaneous ocean egg
In casamino acid sequence, potential many amino acid sequences with bioactivity, with special protease hydrolytic, are just discharged
Active peptide fragment.Marine protein resource is the important of the important albumen group food of the 21 century mankind and bioactive substance
Source.The current marine protein total resources of China comes out at the top in countries in the world, but the current protide aquatic products of China
In product, in addition to a part is directly eaten, major part is made food by simple process technology and enters market, and process technology falls
Afterwards, product structure is single, and value-added content of product is low so that the competitiveness of product in the international market is poor.Therefore, China is badly in need of
Marine protein resource is optimized and utilized and high-valued processing.
