Abstract

The invention discloses a meat degreasing method including steps as follows: (1) meat is cut into blocks and put into a centrifugal machine for dewatering for 10-20 minutes; (2) a degreasing solvent is added into the dewatered meat, the backflow degreasing is performed for 2-3 times at the temperature about 15-20 DEG C higher than the boiling point of the solvent, and each time lasts for 1-3 hours; (3) the solvent in the degreased meat is removed through the centrifugal machine, then the meat is soaked in boiling water and boiled for 2-3 times, each time lasts for 10-15 minutes, and the degreasing solvent and soluble protein as well as decomposition products can be removed; and (4) the meat is air-dried at 70-80 DEG C, and the dried product is frozen at subzero 10 DEG C. The meat degreasing method is safe and convenient, and is more beneficial for health.

Description

A kind of meat degreasing method

Technical field

The present invention relates to a kind of meat degreasing method.

Background technology

The result of study in 10 years by a definite date from the U.S. shows, the meat of process processing such as red meat such as beef, mutton and hot dog intestines, Baconic is eaten manyly more, and health risk is just high more, and can increase the elderly's death rate.For the not joyous people of no meat, this is a bad news.And the expert represents, if the mode health that red meat is eaten, and assurance is inexcessive, still is indispensable in the diet structure.

China Agricultural University's nutrition and any meter of food security owner state represent that the meat that saturated fat levels such as pig, beef or mutton are high is commonly called red meat, and coronary heart disease, heart disease crowd will eat less, but on behalf of us, this to give up red meat.Red meat also has its benefit, is higher than plain boiled pork as the content of vitamin(e) B group and iron.The somebody likes eating the meat of the alternate or pure fertilizer of the girth of a garment, degreasing earlier before eating.

The method of meat degreasing at present mainly contains boiling, fried and add method such as degreasing agent, and fried degreasing often has carcinogen because fried repeatedly in the meat.Which is nutritious for frozen meat and fresh meat? many people think that the nutrition of frozen meat is than fresh meat difference, taste does not have the fresh meat deliciousness yet, actually this is not so, the food brainstrust thinks that food is through helping to kill the growth of some pathogenic bacteria or inhibition morbid substance after freezing, this is useful to health, because the preference temperature of germ reproduction is generally at 20 ℃～40 ℃,, can not reduce fat and protein though some microorganism can grow when being lower than 0 ℃.

Summary of the invention

The purpose of this invention is to provide a kind of meat degreasing method, this method safety, convenience.

The technical scheme that the present invention takes is:

A kind of meat degreasing method may further comprise the steps:

(1) meat is cut into piece and puts into centrifuge dehydration 10-20 minute;

(2) meat after will dewatering adds degreasing solvent, uses than the temperature backflow degreasing of high about 15-20 ℃ of the boiling point of this solvent 2～3 times, each 1～3 hour;

(3) slough solvent in the defatted meat with centrifuge, be dipped in again and boil 10-15 minute 2～3 times in the boiling water, remove degreasing solvent and aqueous soluble protein and decomposition product thereof;

(4) freezing down at the 70-80 ℃ of drying one-tenth dry product of leeward at-10 ℃.

Described degreasing solvent is an ethanol.

Degreasing method safe ready of the present invention is more conducive to health.
