Embodiment 1

[0020] Embodiment 1: The pigeon egg white powder is obtained according to the following method: the first step, at room temperature, a compound enzyme is added to the pigeon egg white to obtain a mixed solution, and then the mixed solution is subjected to an enzymolysis reaction to obtain an enzymolysis product , wherein 20,000 U of compound enzyme is added to every 5 mL of pigeon egg white, and the compound enzyme is composed of papain and neutral protease with a mass ratio of 1:2; in the second step, the enzymatic hydrolyzate is sequentially filtered, pasteurized and sprayed After drying, pigeon egg egg white coarse powder is obtained, and the pigeon egg egg white coarse powder is dry-heat sterilized, cooled and sieved in sequence to obtain pigeon egg egg white powder, wherein, the enzymolysis temperature is 45°C to 50°C, and the enzymolysis time is 150min to 180min.

[0021] In the present invention, pasteurization and dry heat sterilization are known and commonly used tech...

Embodiment 2

[0024] Embodiment 2: As the optimization of the above-mentioned embodiment, in the second step, the feed liquid concentration of spray drying is 25% to 30%, the feed speed is 45r / min to 50r / min, and the inlet air temperature is 120°C to 130°C °C, the outlet air temperature is 70 °C to 80 °C.

Embodiment 3

[0025] Example 3: As an optimization of the above example, in the first step, the pH value of the mixed solution is adjusted to 5 to 7 before the enzymatic hydrolysis.

Abstract

The invention relates to the technical field of pigeon egg deep processing methods, in particular to pigeon egg white powder and a preparation method thereof. The pigeon egg white powder is obtained by the following steps: adding a compound enzyme into pigeon egg white for enzymolysis to obtain an enzymolysis product, then sequentially performing filtering, performing pasteurizing, performing spray-drying, performing dry heat sterilization, performing cooling and performing sieving on the enzymolysis product to obtain the pigeon egg white powder. The preparation method is simple in preparation process, mild in enzymolysis condition, and high in drying speed, the pigeon egg white powder is uniform and consistent in white color and luster, powdery fine particles are good in restorability, easy to absorb, short in dissolution time, good in dispersity and free of agglomeration phenomenon, and the problems that existing fresh eggs are prone to deterioration and breakage and are not beneficial to storage can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of pigeon egg deep processing methods, and relates to pigeon egg white powder and a preparation method thereof. Background technique [0002] my country's fresh egg production ranks first in the world, but the level of deep egg processing is low. With the acceleration of economic globalization and the gradual prosperity of the domestic egg processing market, it is urgent to make full use of existing resources and vigorously develop the egg processing industry. [0003] In recent years, along with the increasing day by day of dove's egg production, how to utilize dove's egg to be applied to food processing industry as food processing auxiliary material has become an urgent issue. Contain a large amount of water in the fresh dove's egg, account for about 68% of whole egg. Removing the moisture from pigeon eggs to a very low level can not only prevent the growth of microorganisms and slow down the chemical rea...
