Description
Technical field
The invention belongs to technical field of aquatic product processing, be specifically related to a kind of keepalive method of Ruditapes philippinarum.
Background technology
Ruditapes philippinarum (claiming sand clam, variegated clam, clam son, a species of small clam living in fresh water, sand a species of small clam living in fresh water, clam, flower clam again), it is the small-sized bivalve shellfish of marine products of a kind of high protein, low fat, amino acid kind composition and reasonable mixture ratio, have higher economic value and nutritive value, report that Ruditapes philippinarum is one of more comprehensive food of the required nutrient of human life activity.Contain a kind of Dai Ertai 7-cholesterol and 24-methylene cholesterol that reduces the serum cholesterol effect that have in the Ruditapes philippinarum, they have concurrently and suppress the unique effect that cholesterol is synthetic at liver and the acceleration cholesterol is drained.Ruditapes philippinarum has that enriching yin makes eye bright, soft heavily fortified point, clears phlegm, the dirty effect of its also useful smart profit, the people of high cholesterol, high fat of blood physique and to suffer from the people of diseases such as thyroid gland enlargement, bronchitis, stomach trouble particularly suitable.The contained glycogen of Ruditapes philippinarum has the effect of antifatigue, and improves human heart and blood circulation, strengthens liver function.Glycogen can directly be absorbed by body, thereby alleviates the pancreas burden, and is therefore very effective to the control of diabetes.The contained glycosaminoglycan of Ruditapes philippinarum is the natural glue between histocyte, has the effect of antitumor, anticoagulation, enhancing immunity, reducing blood lipid etc.In addition, Ruditapes philippinarum delays senility in addition, hypotensive effect.
Along with the raising of people's living standard, shellfish more and more is subjected to people's favor in recent years, and people are also more and more higher to the quality requirement of aquatic products, not only requires nutritiously, more requires product fresh.And that seashell products is organized is tender, the content height of protein and moisture, results or purify after the placement of giving free rein to, the corruption that will soon go bad loses its edibility.This makes the sale of Ruditapes philippinarum be subjected to very big restriction, is difficult to find a good sale in enormous quantities landlocked market and foreign exchange earning.
Summary of the invention
The object of the present invention is to provide a kind of keepalive method of Ruditapes philippinarum, this method can effectively be killed the bacterium in Ruditapes philippinarum surface and the shell or suppress their breeding; Can stop the loss of Ruditapes philippinarum moisture in the keep-alive process, keep the wettability of Ruditapes philippinarum well, transportation or preservation Ruditapes philippinarum can prolong the keep-alive time of Ruditapes philippinarum greatly under the temperature control condition.
For achieving the above object; the keepalive method of Ruditapes philippinarum provided by the invention; Ruditapes philippinarum after catching earlier with the sterilization of hydrogen peroxide maceration extract, again with the mixed aqueous solution of glycerine and the sodium phosphate trimer water conservation of preserving moisture, is then preserved the young packing of clam back or transported and get final product under the temperature control condition.
Further, the keepalive method of Ruditapes philippinarum provided by the invention may further comprise the steps:
