Comprehensive utilization technology of livestock and poultry bones

Abstract

The invention discloses a comprehensive utilization technology of livestock and poultry bones. The comprehensive utilization technology comprises the following steps of (1) taking the livestock and poultry bones, and cooking the taken livestock and poultry bones for 2-4 hours so as to obtain bone soup liquor; and (2) filtering the bone soup liquor so as to obtain bone soup, fat and bone dregs: performing the following three kinds of treatment; (a) performing low-temperature vacuum concentration on the bone soup so as to obtain concentrated bone soup; (b) refining the fat, and performing filtering so as to obtain bone oil; and (c) adding water to the bone dregs, performing treatment by using a colloid mill, performing enzymolysis, adding glucose and amino acids, and performing a Maillard reaction, and then adding a flavoring agent and a thickening agent, and performing emulsification so as to obtain a bone marrow extract. According to the comprehensive utilization technology of the livestock and poultry bones disclosed by the invention, the livestock and poultry bones are used as raw materials for preparing the concentrated bone soup, the bone oil and the bone marrow extract, and the technology is reasonable, and the livestock and poultry bones are comprehensively utilized; nutrient components contained in the livestock and poultry bones are adequately utilized, so that the added value of the livestock and poultry bones is increased, treasure is created for the society, and the environmental pollution is reduced.

Description

technical field [0001] The invention relates to a comprehensive utilization process of livestock and poultry bones. The livestock and poultry bones are used to prepare concentrated bone soup, bone oil and bone marrow extract, which belongs to the technical field of food deep processing. Background technique [0002] Livestock and poultry bones are by-products produced in the slaughtering and segmentation process. They are relatively inexpensive and easy to obtain. They are a potential raw material in food processing and production. Livestock and poultry bones contain a variety of nutrients needed by the human body, and are high in protein and fat, especially calcium and phosphorus. How to comprehensively utilize and deeply process livestock and poultry bones to increase its added value, increase the utilization rate of its nutrients, make it more widely applicable, and have a broader market prospect is one of the technical problems faced in the field of food deep processing ...

AI Technical Summary

Problems solved by technology

[0003] At present, some bone broth manufacturers on the market use livestock and poultry bones to process concentrated bone broth, but their disadvantages are: livestock and poultry bones are extracted multiple times under high temperature and pressure for a long time (the extraction of bone broth is usually 3 to 4 hours, and the temperature is as high as 145 ℃, repeated extraction more than once), the collagen in the bone broth is destroyed, and even burnt flavor appears; multiple long-term high-temperature and high-pressure extractions consume energy (batch extraction of 1 ton of livestock and poultry bone raw materials for bone broth and 3 tons of water heated to Cooking at 145°C for 3 hours and repeated extraction once requires about 2.4 tons of steam and about 0.72 tons of coal, resulting in about 1.87 tons of carbon dioxide emissions, about 2.06 kg of nitrogen oxides, about 0.18 kg of sulfur dioxide, and about 0.13 kg of smoke and dust, reducing 0.22 tons of coal slag), the remaining bone slag has low nutrient content, no use value, and will cause pollution to the social environment
