Method for producing peptone by taking poultry feather as raw material

Abstract

The invention discloses a method for producing peptone by taking poultry feather as a raw material. The method comprises the following steps: performing pretreatment on the poultry feather raw material, and then sending into a microwave puffing machine for treatment; adding keratinase for performing enzymolysis reaction and heating for enzyme deactivation; adding activated carbon to perform deodorization, peculiar smell removal, decolorization and other treatment, and filtering; and performing evaporation concentration and high-speed centrifugal spray-drying, and getting the peptone after drying. According to the method disclosed by the invention, the combination of microwave puffing and keratinase enzymolysis technologies is adopted for producing the peptone by taking the poultry feather as the raw material, a new way is opened for resource utilization and development of the waste feather, and the resource utilization is performed on the poultry feather produced during cultivation, so that environmental pollution and the waste of resources are reduced, social benefits are increased, the cost of the raw material is low, process equipment is simple, the process flow is simple and strong in operability, and the industrial production can be realized; the peptone produced by the method disclosed by the invention has good quality and high yield; and the method disclosed by the invention can fill in the technical blank in preparation of the peptone by taking the feather as the raw material.

Description

technical field [0001] The invention mainly relates to a method for producing peptone, in particular to a method for producing peptone using poultry feathers as raw materials. Background technique [0002] At present, the development momentum of my country's animal husbandry industry is strong, and the proportion of animal husbandry production in agricultural production is increasing. The breeding method is also changing from the traditional breeding model to the large-scale and intensive model. Large-scale poultry breeding produces a large amount of feather waste. According to the statistics of the China Animal Husbandry Association, the annual poultry production in my country has exceeded 20 million tons in recent years, and the breeding volume of ducks and geese ranks first in the world, reaching 7.713 billion and 3.373 billion respectively (China Animal Husbandry Association, 2009). The feathers account for 5%-7% of the poultry weight. According to this calculation, the a...

Problems solved by technology

[0004] The production of peptone from poultry feather waste was only seen in "Trial Production of Peptone by Direct Hydrolysis of Waste Feather" reported on pages 13-14 of the 11th issue of "Today's Science and Technology" in 1975. The main process is at a liquor ratio of 1:15 and a pressure of 4Kg. / cm 2 Maintained under the same conditions for 36 hours, the process is simple, but limited to the equipment and technical level at that time, the yield is low, the quality is poor, and industrial production has not been formed; there is no report on the patented invention of preparing peptone from poultry feathers
