[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

Embodiment 1
[0009] A method for enzymatic hydrolysis of bone dregs. Take 20kg of fresh chicken bones, mix well, add 20kg of water, select alkaline protease for enzymolysis, add 25g of alkaline protease, enzymolyze at 55°C for 1.5 hours, and enzymolyze Afterwards, the enzyme was inactivated for 10 minutes under the condition of 80°C.
[0010] After washing the sample with water and filtering the residue, and drying the remaining residue naturally, the amount of residue after enzymatic hydrolysis of the chicken bone residue was 36.37%.
Embodiment 2
[0012] A method for enzymatic hydrolysis of bone dregs. Take 20kg of fresh chicken bones, mix well, add 20kg of water, select compound protease for enzymolysis, add compound protease 30g, enzymolyze at 60°C for 2.5 hours, and extinguish after enzymolysis. Enzyme 20min.
[0013] After washing the sample with water and filtering the residue, and drying the remaining residue naturally, the amount of residue after enzymatic hydrolysis of the chicken bone residue was 32.47%.
Embodiment 3
[0015] A method for enzymatic hydrolysis of bone dregs. Take 20kg of fresh chicken bones, mix well, add 20kg of water, select neutral protease for enzymolysis, add 40 g of neutral protease, and enzymolyze at 65°C. Then inactivate the enzyme for 20 min.
[0016] The sample was washed with water and the residue was filtered, and after the remaining residue was dried naturally, the amount of residue after enzymatic hydrolysis of the chicken bone residue was 33.25%.

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...
