Abstract

The invention discloses a compound film coating agent for fresh keeping of blue peacock eggs and a preparation method thereof. The preparation method of the compound film coating agent comprises the following steps: A, preparing Chinese herbal medicine mixed extract; and B, mixing the Chinese herbal medicine mixed extract, propolis, chitosan, tea polyphenol and the like, adding absolute ethyl alcohol, and performing stirring for complete dissolving to obtain a compound film coating agent product. The compound film coating agent for fresh keeping of blue peacock eggs which is ecologically safe,simple and convenient to produce, low in cost and high in commercialization degree is researched and developed by comprehensively utilizing the resource and combination characteristics of natural film-forming agents such as propolis and extracts of Chinese herbal medicines such as honeysuckles, and the market requirement for prolonging the peacock egg storage shelf life is met.

Description

technical field [0001] The invention relates to the technical field of preservation of eggs, in particular to a compound coating agent for preservation of blue peacock eggs and a preparation method thereof. Background technique [0002] Peacocks belong to the class Aves in zoology ( Ayes ), Galliformes ( Galliformes ), Phasianidae ( Phasianidae ), Peacock ( Pavo ), there are two kinds of blue peacock and green peacock. The blue peacock, also known as the Indian peacock, is a special economic bird that can be raised without protection, and has high edible and medicinal properties. [0003] The protein content of blue peacock eggs (15.554g / 100g) is much higher than that of chicken eggs (12g / 100g) and duck eggs (10-13g / 100g). The fat content of blue peacock eggs is less than that of eggs of several different varieties (32.51%, 35.42% and 34.65%), and the cholesterol content is lower than that of chicken eggs. The contents of essential amino acids (EAA) and non-essentia...
