Abstract

The invention relates to a method for accelerating the dissolving out of poultry-bone nutrient substances. The method disclosed by the invention comprises the following steps: (1), cleaning and neatening selected poultry bone; (2) quickly freezing the poultry bone, then crushing the poultry bone by a bone crusher, and crushing the poultry bone into poultry-bone mud by a bone mud machine; (3) preparing nutrient liquor; (4) preparing fermentation liquor, inoculating microorganisms selected for fermentation, which comprise lactobacillus casei, lactobacillus plantarum and staphylococcus xylosus in a proportion of 1:3:3, wherein the concentration of inoculated bacteria suspension liquid is 108cfu / ml, and inoculating ranges are respectively 3%, 9% and 9%; (5) inoculating the poultry-bone mud, and then fermenting the poultry-bone mud in a fermentation box; (6) pressurizing and leaching by adopting organic acid; and (7) adjusting pH of the leaching liquor to be 7.0 by adopting edible soda ash, and filtering to remove un-dissolved bone slag. The extracting liquor treated by the method disclosed by the invention is rich in nutrition and has an extremely high utilization value.

Description

technical field [0001] The invention relates to a poultry bone processing method, in particular to a method for accelerating the dissolution of poultry bone nutrients, and belongs to the technical field of poultry deep processing. Background technique [0002] Skeleton is the main part of poultry production, and as the main by-product of poultry processing products, skeleton is quite high, accounting for about 8%-17% of carcass weight, but the utilization rate is extremely low. Although poultry bone is a by-product of poultry meat production, it is quite rich in nutrients. Among them, the protein content is 15%-18%, the fat content is 8%-12%, the water content is 58%-62%, and it is rich in calcium, Phosphorus, iron, zinc and other trace elements. The main nutritional components of chicken bones are protein, fat and minerals. It is a high-nutrition and low-calorie food, which contains 10.35% protein, 13.44% fat, 3.95% calcium, and 2.04% phosphorus. It also contains various t...
