Processing technology of frying beef fillet and products thereof
One, technical field
The present invention relates to frying beef fillet meat processing technology and product, belong to food processing technology field.
Two, background technology
Now, Australia, the U.S. and Britain all set up and have implemented the meat edible quality and guarantees key control technology (Palatability assurance eat critical control points, PACCP), this technology mainly by from heredity, raise, butcher the key link control of processing, with the mouthfeel and the quality of assurance final products until meat production whole process such as cooking processing etc.In the U.S., implement the meat mouthfeel and guarantee that system mainly concentrates on following 3 fields: (1) determines to improve the genetic marker of the tender degree of meat in the seed selection process; (2) set up and detect the CCP of tenderness of beef utilizing, as give high-octane meals before killing, adopt electro photoluminescence when butchering, carry out natural maturity etc. after killing; (3) thus the automatic classification technique of exploitation guarantees that the good more price of tender degree is high more, raise the domestic animal of high tender degree to stimulate the raiser.In order to improve the edible quality of meat, Chinese scholars has been carried out many researchs, think that influencing the factor of meat edible quality mainly contains following several respects: the kind of domestic animal, age, nutrition condition, sex, process for butchering, biochemistry behind the government official changes, processing method etc., its basic reason is the institutional framework of muscle and kills the artifact chemical change, particularly depends on the state (being the tightness degree that myosin combines with actin) of fribrillin in the muscle, the composition of connective tissue and content, the size of the distribution of intramuscular fat and content and muscle retentiveness etc.Because influence factor is various, the edible quality difference of meat is great disparity quite, how could guarantee the uniformity of meat quality, be one of problem of domestic and international many meat scientific worker researchs, and they has also provided scientific research as foundation.But I find that for processing in the research aspect the beef edible quality seldom, especially domestic, therefore, the introduction and the research of PACCP technology have profound significance.
Beef is in process, because various different mouthfeel can appear in the influence of various inherences, external factor.Internal factor, as the character that processes raw material also has confidential relation with the osmosis of distinguishing the flavor of, as joint because its musculature is fine and close more, under same cooking conditions, compare with fritter meat, it is slow that the seepage velocity of its flavouring is wanted, and fat meat is many because of fat content, compares with lean meat, it is slow that the seepage velocity of its flavouring is wanted, and it is easier to be tasty that fresh meat will compare inferior fresh meat; External factor, as the type of meat cooking method, in western-style food, dry heating method and wet heating are the basic cooking methods of two big classes, therefore, by the research to various influence factors, we can draw optimum process condition at last.The traditional diamond-making technique of China does not also catch up with the requirement of modern science at nutrition, health, production, management aspect, be difficult to participate in the keen competition of eating market, the world, thereby the processing of China must be walked scientific, modernized road.The PACCP technology is by repetition test and investigation, for production technology provides the scientific quantitative foundation, thereby makes the suitability for industrialized production of meat products become possibility.Help the production of meat products processing industry to realize standardization, can promote the scientific, modernized of China's processing.
China is beef big producing country, but process technology and level are all very low, and the cooking method of beef is varied, edible quality after the cooking is also uneven, therefore be necessary to find the processing method of a kind of science, standard,, improve the quality of products to improve its edible quality.
