Abstract
The invention discloses an animal and poultry carcass humectant and a preparation method thereof. The animal and poultry carcass humectant provided by the invention comprises the following substances by weight percent: 12.5%-16.5% of monoglyceride, 4.5%-8.5% of salad oil, 0.5%-1.5% of lactic acid, 0.5%-1.5% of chitosan and 75%-79% of water. The preparation method comprises the following steps of: adding the monoglyceride and the salad oil into the water above the temperature of 67 DEG C and dissolving; and then stopping heating, continuously adding the lactic acid and the chitosan into the water, uniformly mixing, and cooling to obtain the animal and poultry carcass humectant. Compared with the existing method for reducing the pre-cooling loss of a carcass, the animal and poultry carcass humectant provided by the invention has significant effect in the aspect of reducing the pre-cooling loss; furthermore, the humectant is low in preparation cost and convenient to operate; in addition, the quality of a product is not affected and the significant economic benefits are achieved.
Description
Technical field
The present invention relates to a kind of live pig trunk NMF and preparation method thereof and application.
Background technology
The precooling loss be hot trunk in cooling procedure because of cold and hot exchange forms, product comes release heat through the moisture that evaporates self, the evaporation of its moisture is inevitable and irreversible.The precooling loss is the result of a plurality of factor interactions, and it forms existing external cause, and internal cause is also arranged: external cause is a precooling technology, and internal cause is the quality of product self.Reduce the precooling loss of live pig trunk and butcher yield rate, increase muscle retentiveness and meat quality, thereby it is significant to obtain better economic benefit for raising.
The America and Europe butchers industry and notices very early, and there is bigger water evaporates loss in the live pig carcass in precooling process.For example, the pig informal voucher is during precooling, if condition is incorrect, in the 24h of beginning precooling, its precooling loss can reach more than 3%.As far back as the seventies in 20th century, foreign study find to reduce the temperature of precooling environment, increases the relative humidity of environment, reduces the circulation wind speed on carcass surface, can both reduce the loss in weight during the carcass precooling effectively.
Correlative study shows through reducing the precooling environment temperature, reduce carcass surface air velocity, being coated with method such as one deck thin cellulose film directly to carcass body surface water spray, even at meat surface, can suppress and hinder the water evaporates in the carcass precooling process.The cooling device that also has the scholar to invent a kind of ice bank cools off poultry meat, fruit, vegetables etc.This equipment is that the high humidity cold air (temperature constant is at 0 ℃, and relative humidity can reach 99%) that utilizes mixture of ice and water to produce cools off food.Bristol, UK food research association discovers: in the 24h that the pig carcass begins to cool down; The highly humid air (relative humidity is up to 99%) that uses cooler to produce comes the precooling carcass; Compare the former 0.4% (Ku Wen is 2 ℃) that can reduce the wastage with traditional cold air (relative humidity 90%) precooling.If after continuing cooling 48h, adopting the carcass loss of conventional cooling methods is 3.31%, the carcass loss of cooling method is 1.94%.
For shortening the precooling time, some scholar also attempts with the method for liquid nitrogen immersion 30s meat being cooled off, and this method effect is obvious, but its equipment drops into and operating cost is but quite high.For example, aspect the precooling of pig carcass, if adopt the immersing in liquid nitrogen precooling, the precooling loss of pig informal voucher can be reduced to 0.32%.
In recent years, what external butchery application was more is improved two sections cooling methods, and hot informal voucher is after finishing finishes; Get into suddenly rapidly and freeze the storehouse, cooling fast treats that internal temperature changes the precooling storehouse over to and carries out balance when reaching 7 ℃ about-30 ℃; In 16-20h, the carcass internal and external temperature can equilibrate to below 4 ℃.Also some slaughterhouse is when selling informal voucher meat, and hot informal voucher utilization-30 ℃ environment is anxious when freezing carcass to internal temperature and reaching 7 ℃, adorns the refrigerator car transportation immediately, makes carcass internal and external temperature balance voluntarily in transportation.
Summary of the invention
The purpose of this invention is to provide a kind of livestock body NMF and preparation method thereof.
Livestock body NMF provided by the present invention is made up of the material of following quality percentage composition: monoglyceride 12.5%-16.5%, salad oil 4.5%-8.5%, lactic acid 0.5%-1.5%, shitosan 0.5%-1.5% and water 75%-79%.

Above-mentioned livestock body NMF specifically can be used as live pig trunk NMF.
The method for preparing above-mentioned livestock body NMF comprises the steps: in the water more than 67 ℃, to add monoglyceride and salad oil and dissolving; Stop heating then and in said water, continue adding lactic acid and shitosan and mixing, cooling obtains said livestock body NMF.
Concrete preparation process is following:
1) in agitated reactor with water heating and remain on more than 67 ℃, said monoglyceride is added stirring and dissolving in the agitated reactor;
2) with adding behind the cold water mixing of said salad oil and equivalent in the agitated reactor of step 1), before the adding salad oil water temperature in the step 1) agitated reactor is remained on more than 67 ℃, stirring is all dissolved salad oil;
3) make step 2) agitated reactor cooling, and to wherein adding said lactic acid, stir it mixed;
4) in the agitated reactor of step 3), add said shitosan, stirring mixes it; Add cold water at said agitated reactor interlayer and make the solution cooling, whenever stirred 1 minute in the cooling procedure, be cooled to 40 ℃, promptly get said livestock body NMF at a distance from 10 minutes.
Livestock body NMF of the present invention can be coated in the livestock body surface, is used to reduce the precooling loss of livestock body.Said livestock body specifically can be the live pig trunk.
Compare with the existing method that reduces trunk precooling loss, NMF provided by the invention effect aspect reduction precooling loss is remarkable, and the preparation cost of this NMF is low, and is easy to operate, and do not influence the quality of product, remarkable in economical benefits.
