Production process of bovine bone peptone

Abstract

The invention provides a production process of bovine bone peptone. The production process specifically comprises the following steps: A, dissolving materials, namely adding water into a raw material bovine bone cream while stirring, wherein the bovine bone cream contains 16-25% of beef; B, adjusting the pH value, namely adjusting the pH value of a material solution to 7.8-8.2 at a constant temperature of 48-54 DEG C while continuously stirring; C, performing enzymolysis, namely carrying out enzymolysis for two times, adding a biological enzyme into the material liquid at twice while continuously stirring, and performing constant-temperature enzymolysis for 4-6 hours, wherein the pH value during the whole enzymolysis process is kept between 7.8 and 8.2; D, performing enzyme deactivation, namely after enzymolysis, adjusting the pH value to be 6-6.5, heating the material liquid to 75-85 DEG C while continuously stirring, then adding diatomite, and boiling for 5-10 minutes; and E, obtaining a finished product, namely filtering, concentrating and drying the material liquid to obtain the finished product. The production process is advanced in technology and reasonable in process route, and a peptone product is good in quality and low in water and ash content, and is suitable for industrial application.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a production process of bovine bone peptone. Background technique [0002] my country is a big consumer of poultry and livestock. Bone resources are extremely rich, and its nutritional value is also very high. It is a high-quality protein source. However, the consumption of poultry and livestock in our country is often limited to the utilization of poultry and livestock meat, and a large number of poultry and livestock bones are not fully utilized, resulting in a huge waste of resources and environmental pollution. Among them, bovine bone is particularly serious, so it is of great significance to prepare peptone from bovine bone. [0003] Peptone is a pale yellow powder obtained by hydrolyzing meat, casein or gelatin with acid or protease and then dried. It can also be a water-soluble mixture obtained by decomposing protein with acid, alkali or protease. Pe...

AI Technical Summary

Problems solved by technology

[0006] 1. It is necessary to cook the beef bone for several hours under the high temperature condition of 120-150 ℃, the energy cost is high, and it is relatively unsafe

[0007] 2. The enzymatic hydrolysis process does not specify which enzyme or which enzymes are compounded in what amount, and the corresponding temperature, pH and time range are also relatively large

[0008] 3. Put the product into the drying tray for drying, it is easy to cause the laying thickness of the product to be dried in the drying tray to be different, and the moisture content of the finished product is significantly different
