Problems solved by technology

By searching domestic and foreign literature in the past ten years, there are almost no research reports on the deep development and utilization of chicken feet peeling, and scientists in related fields have not received due attention. There are very few related studies, so the current understanding of chicken feet skin is very limited

Embodiment 1

[0006] The chicken feet skin is pulverized, passed through a 30-mesh sieve to obtain the chicken feet skin powder, and degreased with n-hexane to obtain the defatted chicken feet skin powder. Accurately weigh 30g of chicken feet skin degreasing raw materials, add 1000mL of 1.5% sodium hydroxide solution, heat in a water bath at 70°C and stir continuously for 7 hours, centrifuge at 3500r / min for 15min, take the supernatant and dehydrate to obtain chicken feet Skin protein products, the extraction rate of chicken feet skin protein is 84.2%.

Embodiment 2

[0008] The chicken feet skin is pulverized, passed through a 30-mesh sieve to obtain the chicken feet skin powder, and degreased with n-hexane to obtain the defatted chicken feet skin powder. Accurately weigh 30g of chicken feet skin degreasing raw materials, add 1200mL of 1.5% sodium hydroxide solution, heat in a water bath at 60°C with constant stirring for 5 hours, centrifuge at 3500r / min for 15min, take the supernatant and dehydrate to obtain chicken feet Skin protein products, the extraction rate of chicken feet skin protein is 83.6%.

Embodiment 3

[0010] The chicken feet skin is pulverized, passed through a 30-mesh sieve to obtain the chicken feet skin powder, and degreased with n-hexane to obtain the defatted chicken feet skin powder. Accurately weigh 30g of chicken feet skin degreasing raw materials, add 1000mL of 1.5% sodium hydroxide solution, heat in a water bath at 65°C and stir continuously for 6 hours, centrifuge at 3500r / min for 15min, take the supernatant and dehydrate to obtain chicken feet The skin protein product, the extraction rate of chicken foot skin protein is 84.1%.

Abstract

The invention discloses a method for extracting proteins in chicken foot skin through an alkaline process and belongs to the technical field of utilization of agricultural and sideline products. The method comprises the following steps: by taking chicken foot skin as a raw material, crushing the chicken foot skin, allowing the chicken foot skin to pass through a sieve with the granularity of 30 meshes to obtain chicken foot skin powder, and degreasing the chicken foot skin powder by using normal hexane to obtain degreased chicken foot skin powder; and accurately weighing 30g of chicken foot skin degreasing raw material, adding 1000-1200mL of 1.5% sodium hydroxide solution, heating in a water bath at the temperature of 60-70 DEG C, continuously stirring for 5-7 hours, centrifuging at a speed of 3500r / min for 15 minutes, and dehydrating the supernatant to obtain a chicken foot skin protein product, wherein the extraction rate of the proteins in the chicken foot skin is 83.5 percent.

Description

technical field [0001] The invention discloses a method for extracting protein from the skin of chicken feet by an alkaline method, which belongs to the technical field of utilization of agricultural by-products. technical background [0002] According to the forecast of FAPRI of the United States, by 2018, the global broiler chicken production will be close to 80 million tons, and the annual growth rate will still be 2% in the future, while China may be higher than the world, reaching 2.5%. In 2011, my country's broiler chicken output was 13.2 million tons, accounting for about 17% of the total meat, an increase of 5% over 2010. In 2012, the output reached more than 13.8 million tons. The skin of chicken feet is different from the skin of mammals. During the processing of chicken feet, the skin can be removed by scalding with hot water. Get about 100,000 tons of chicken foot skins in the world every year. Long-term discarded accumulation will cause great harm to the ecolog...
