Abstract
The invention provides a freezing point modifier for large yellow croaker ice-temperature fresh-keeping and usage thereof. The freezing point modifier comprises raw material components in parts by weight: 10 -20 parts of salt, 1-5 parts of sorbitol, 0.1-0.5 parts of vitamin C, 5-10 parts of calcium chloride, and 8-12 parts of natrium aceticum. According to the modifier, the freezing point of large yellow croaker can be greatly lowered, the ice temperature zone range of large yellow croaker can be enlarged, the requirement on equipment temperature control accuracy can be lowered, the additive amount of the freezing point modifier is less, the cost is saved, the construction cost of an ice temperature storehouse can be reduced, therefore, the method is beneficial to the popularization of ice temperature preservation technology.
Description
Technical field
The invention belongs to the food preservative technology field, specifically a kind of freezing point modifier and using method for the large yellow croaker ice temperature fresh-keeping.
Background technology
Large yellow croaker belongs to Perciformes, Sciaenidae, and the title of " state fish " as famous and precious economic fish, is arranged, and favored by the consumer, also is considered as mascot, " long life fish ", is the excellent gift in red-letter day.The large yellow croaker meat is fine and smooth, delicious flavour, contain rich in protein, trace element (is rich in trace elements of selenium especially, can remove the free radical that body metabolism produces, delay senility, and various cancers had prophylactic-therapeutic effect) and vitamin, human body there is good benefiting action, concerning have a delicate constitution and the elderly, the wine plant fish can be received good food therapy effect.The traditional Chinese medical science thinks that yellow croaker has invigorating the spleen to rise stomach, calm the nerves and end the effect of dysentery, beneficial gas replenishing essence, and anaemia, insomnia, dizziness, poor appetite and women's postpartum weakness are had good efficacy.Therefore very high economic worth and nutritional health function are arranged.Along with the output of marine fish increases year by year, the processing of cultured product just becomes key issue anxious to be resolved.The processing of aquatic products output of China, to be finished by Shandong, Zhejiang, Fujian, Guangdong, Liaoning, seven maritime provinces in Jiangsu and Guangxi more than 90%, it is the first that wherein the output value of Shandong processing of aquatic products occupies the whole nation, Zhejiang only occupies the 4th, and compare according to the processing of aquatic products benefit ratio of the output value (output with), Zhejiang can only occupy the 5th.Continuous maturation and popularization along with the deep-water net cage culture technology, the quality of marine fish has had very large improvement, studies show that, the nutritional labeling of the large yellow croaker of deep-water net cage culture and flesh quality are almost near wild large yellow croaker, but during the whole 11th Five-Year, the marine fish culture annual production of our province is in level stable with a slight decline, the situation that high yield is not had a good harvest occurs.Analyze reason, wherein the processing of cultured product is one of major reason of restriction cultivation popularization, output increased, and therefore, the fish processing industry of our province is faced with formidable challenges, and the processing of cultured fishes has become the bottleneck of restriction mariculture industry development.
Icetemperature Storage is fresh-keeping be with food storage 0 ℃ with in the scope of separately chill point, be to belong to non-Cryopreservation, be the third generation preservation technique after refrigeration, CA storage.Icetemperature Storage is that former Ribenniaoqu County food processing director of the Institute, the existing Japan ice clear beautiful doctor in president mountain root of warm association proposed in the 70's of last century the earliest.Aspect storage effect, to compare with traditional preservation technique, ice-temperature technique has following advantage: (1) does not destroy cell; (2) suppress to greatest extent the harmful microbe activity; (3) suppress to greatest extent respiration, prolong storage period; (4) improve to a certain extent the qualities of fruit, vegetables.The essential idea of " Icetemperature Storage technology " thinks that exactly stored goods are the lived live bodies of tool, after through the cooling processing under the certain condition, make the storage product reach the state of a kind of approximate " hibernation ", thereby allow product under " hibernation " state, preserve, at this moment product metabolism rate is minimum, the energy that consumes is minimum, can effectively preserve quality and the energy of product, and make life reach the longest.Research finds that the process that realizes " hibernation " state of product is to determine the fresh-keeping key of Icetemperature Storage." hibernation " process that realizes product is a cool down, in this process, product is regulated by self adaptation, from the composition in the histocyte changes, the mobility of oneself is reduced, reducing energy consumption, guarantee again simultaneously the live body vital signs of oneself, is a typical natural adaptation phenomenon.
Ice temperature control device temperature fluctuation in the market is larger, and generally at ± 2 ℃, and the ice temperate zone of aquatic products is narrower, generally at ± 0.5 ℃, does not satisfy the requirement of the warm preservation of ice; And special-purpose ice temperature control equipment price is expensive, and operating cost is higher, and general enterprises is difficult to bear.Therefore develop suitable freezing point modifier, to enlarge the ice temperate zone scope of cultured large yellow croaker, reduce the requirement to the equipment accuracy of temperature control, also can reduce the construction cost of ice Wen Ku, therefore be conducive to ice popularizing of warm preservation technology.
