Description

One kind is antibacterial using pasteurize combination nano zine oxide and radio frequency sterilization extends salt solution The method of goose shelf-life
Technical field
Guaranteed the quality with the sterilized extension salted water goose of radio frequency using pasteurize combination nano zine oxide is antibacterial the present invention relates to one kind The method of phase, its shelf-life that can extend product, can maintain the qualities such as color and luster, local flavor, the tenderness of salted water goose again, belong to meat system Product processing technique field.
Background technology
Salted water goose is the traditional meat of China Operation in Yangzhou Area, with fresh, tender, nutritious, fragrant taste, light taste The features such as, it is deep to be liked by consumer.In order to keep the qualities such as the distinctive local flavor of salted water goose, tenderness, color and luster to be killed frequently with relatively low Bacterium temperature and time, but if the initial strip bacterium number of goose is too high or process in microorganism pollution it is more serious, just It is easily sterilized not thorough, so as to cause its shelf life short, it is not easy to transport for long-distance and stores.Vacuum packaging salted water goose storage period The change of quality mainly due to physical factor, chemical factor, microbiological factor and in meat caused by the effect of endogenous enzymes, by Endogenous enzymatic inactivation in product can make meat in boiling and sterilization process, therefore physics and chemical factor are to storage period meat Product property change influence is smaller, and microorganism and the physical and chemical quality deterioration caused by microorganism turn into influence shelf life Principal element.Salted water goose microbiological pollution has had more research, Wei Jinrong etc.(2012)Invent a kind of goose surface The lossless detection method that bacterium directly counts, Dong Yang etc.(2012)To microorganism pollution in vacuum-packed salted water goose process Situation and bacterial diversity are studied, Zheng Anjian etc.(2006)CCP to microorganism in salted water goose process It has been careful research, Ge Qinglian etc.(2015)The risk analysis of salted water goose quality safety and control strategy are studied, therefore Salted water goose must find suitable method for disinfection to keep its distinctive quality.
According to the difference of processing temperature, cooked meat product can be divided into two kinds of high temperature meat product and low-temperature meat product.High temperature meat system Product are sterilized for a long time frequently with 121 DEG C, can not only kill the microorganisms such as deathly bacterium, fungi, also have killing to brood cell, spore Can be serious with the destruction of the nutritional ingredients such as the amino acid in long-term storage, but meat, vitamin, protein under effect, normal temperature, muscle bullet Property reduce, loss of aroma it is serious, quality decline.Low-temperature meat product uses pasteurize, compared with high temperature meat product, pasteurize The features such as meat products has pure nutritious, close structure, meat flavour, attractive color, delicate mouthfeel, but due to sterilization intensity It is low, the weaker microorganism of part heat resistance can only be killed, and the stronger microorganism of some heat resistances such as spore, gemma remain to deposit Living, therefore the method for disinfection is used alone need to carry out accumulating, sale under cold chain.
Nano-ZnO is a kind of new functional nanomaterials, and its particle is thin, activity is high, with infrared resistant, ultraviolet Line and sterilizing function, can effectively kill and suppress staphylococcus aureus, Escherichia coli, bacillus in food etc. various Microorganism.The stability and security of zinc oxide are preferably, nontoxic edible, do not decompose, and never degenerate, and heat endurance is good, is eaten by the U.S. Product Drug Administration is considered one of 5 kinds of safe compounds of zinc( 21CFR182.8991).GB/T 13106-1991 In define zinc content in meat and must not exceed 100 mg/kg.Food is processed by nano zine oxide, although microorganism energy A certain degree of control is obtained, but is difficult by control of microorganisms in safe range, therefore nano zine oxide needs to combine it His sterilization technology, just can preferably control the growth of microorganism, it is ensured that the edible safety of food.
