Enzymolysis method for bone dregs

Abstract

The invention discloses an enzymolysis method for bone dregs, which comprises the following steps of: adding water into the bone dregs, wherein the adding amount of the water is 1 to 2 times mass of the bone dregs; adding enzyme in a mass which is 0.1 to 0.2 percent of the mass of the bone dregs, performing enzymolysis at the temperature of between 55 and 65DEG C for 1.5 to 3 hours; and killing enzyme at the temperature of between 80 and 95DEG C for 10 to 20 minutes. The added value of the bone dregs is improved. By the enzymolysis method, the effect of separating meat from the bone dregs is better, the bones and the meat are separately thoroughly, the hydrolysis effect is good, and the residue amount is 26 to 43 percent. The enzymolysis solution has rich main free amino acids, the total content of amino acids and the content of essential amino acids in protease enzymolysis solution are respectively 14.97mg.g<-1> and 8.92mg.g<-1>, and the content of glutamic acid and the content of aspartic acid are respectively 1.951mg.g<-1> and 1.257mg.g<-1>.

Description

technical field [0001] The invention relates to an enzymatic hydrolysis method, in particular to an enzymatic hydrolysis method of bone dregs. Background technique [0002] my country is a big country in meat production, consumption and trade in the world, with an annual meat output of about 80 million tons, while animal bones account for about 10% to 30% of carcass weight, and an annual output of about 20 million tons of fresh bones, such as chicken bones, pig bones, etc. bone, bovine bone, etc., but less than 2% of them are deeply processed, causing great waste. At present, a large number of skeletons are directly sold at a low price, or the fresh meat left on them is obtained through a bone and meat separator, and the waste residue discharged is commonly known as bone residue, and the price is even lower. [0003] In recent years, in addition to being used to produce feed, bone dregs are partially made into bone paste, and then further processed into bone paste food, such...

Problems solved by technology

[0002] my country is a big country in meat production, consumption and trade in the world, with an annual meat output of about 80 million tons, while animal bones account for about 10% to 30% of carcass weight, and an annual output of about 20 million tons of fresh bones, such as chicken bones, pig bones, etc. Bone, beef bone, etc., but less than 2% of them are deeply processed, resulting in great waste

However, due to the fishy smell of the bone itself and the graininess after crushing, it brings inconvenience to the production of the product, and most bone paste foods cannot be accepted by consumers

At present, there is a high-temperature and high-pressure extraction technology to produce osteoin to solve the problem of bone residue resource utilization. However, in the face of a large amount of low-cost bone residue that is a pity to discard, it is difficult for enterprises to digest it in time if all of it is produced, and a large amount of investment is required. equipment and duplication
