Embodiment 1

[0022] Select 5kg of Tibetan yak bones, wash to remove sundries, fur, blood, etc. The cleaned yak bone is subjected to high-pressure cooking, the cooking temperature is 150°C, the pressure is 0.6Mpa, and the time is 1.5h. Then dry at 60°C for 10 minutes. The above-mentioned yak bone was crushed for 15 minutes by using a mechanical pulverizer to obtain yak bone powder with a particle size of 200 μm to 500 μm. Grinding with GNM series bone mud mill for 15 minutes at a temperature of 65°C to 75°C, the particle size of yak bone powder is below 100 μm. At room temperature, the above-mentioned yak bone powder is pulverized by airflow, the air pressure is 0.6Mpa, and the gas-solid ratio is 2:1. Drying with hot air at 70 DEG C to 80 DEG C, the obtained yak nano bone powder has a particle size of 100 nm to 300 nm and a water content of 1.53%.

Embodiment 2

[0024] Select 20kg of Tibetan yak bones, wash to remove sundries, fur, blood, etc. The cleaned yak bone is subjected to high-pressure cooking, the cooking temperature is 160°C, the pressure is 0.6Mpa, and the cooking time is 1.5h. Then dry at 60°C for 20 minutes. The above-mentioned yak bone is crushed for 20 minutes by using a mechanical pulverizer to obtain yak bone powder with a particle size of 200 μm to 500 μm. Grinding with GNM series bone mud mill for 20 minutes at a temperature of 65-75°C, the particle size of yak bone powder is below 100 μm. At room temperature, the above-mentioned yak bone powder is pulverized by airflow, the air pressure is 0.7Mpa, and the gas-solid ratio is 2:1.5. Drying with hot air at 70 DEG C to 80 DEG C, the obtained yak nano bone meal has a particle size of 100 nm to 300 nm and a water content of 1.66%.

Embodiment 3

[0026] Select 100kg of fresh Tibetan yak bones, wash and remove sundries, fur, blood, etc. The cleaned yak bone is subjected to high-pressure cooking, the cooking temperature is 180°C, the pressure is 0.6Mpa, and the time is 1.5h. Then dry at 65°C for 20 minutes. The above-mentioned yak bone was pulverized for 30 minutes by using a mechanical pulverizer to obtain yak bone powder with a particle size of 200 μm˜500 μm. Grinding with GNM series bone mud mill for 25min at a temperature of 65°C to 75°C, the particle size of yak bone powder is below 100μm. At room temperature, the above-mentioned yak bone powder is pulverized by airflow, the air pressure is 0.7Mpa, and the gas-solid ratio is 3:1. Drying with hot air at 70 DEG C to 80 DEG C, the obtained yak nano bone meal has a particle size of 100 nm to 300 nm and a water content of 1.75%.

Abstract

The invention provides a processing method of nano yak bone powder. The processing method comprises the following steps: selecting and cleaning yak bones; stewing; drying; performing primary pulverization; performing secondary pulverization; performing ultra-fine air stream pulverization, dewatering and other process steps to obtain the finished product of the nano yak bone powder. The obtained nano yak bone powder product has the advantages of particle size up to 100-300nm, uniform dispersibility and good taste, and can be absorbed easily; and meanwhile the nano yak bone powder can be taken as a nutritive food additive to be widely applied to foods such as meat products, pastries, seasonings and the like.

Description

technical field [0001] The invention relates to a processing method of yak nano-bone powder, belonging to the technical field of food processing. Background technique [0002] In the chemical composition of fresh bone, water accounts for 40% to 50%, collagen accounts for 20% to 30%, and inorganic matter accounts for about 20% (mainly calcium and phosphorus). Fresh bone also contains a large amount of calcium, phosphorus, magnesium, sodium, iron, zinc, potassium, fluoride and citrate, and its mineral elements are several times that of fresh meat. [0003] Yaks are one of the characteristic species of the Qinghai-Tibet Plateau, and most of them live and thrive in the alpine regions of the Qinghai-Tibet Plateau with an altitude of more than 3,000 meters. Because yaks live in pollution-free natural alpine regions for a long time, the whole body of yaks has in-depth development value. Among them, the bones accounting for 1 / 3 of the total biomass of yaks are rich in nutrients, no...
