The embryonated egg is processed to prepare beverage which can be drunk at any time without being limited by raw materials.
CN 103462165A discloses a process for producing a beverage of embryonated egg, which comprises the steps of disinfecting the egg surface of qualified embryonated egg, removing egg shell, and mashing into slurry with a tissue mashing machine to obtain embryonated egg raw slurry, wherein no visible granular substance exists, and the granularity of the granular substance reaches 50 meshes; adjusting the pH value of the chicken embryo egg raw slurry to 6.5-6.8 by using rice vinegar, then adding a complex enzyme for stirring uniformly, performing heat preservation and enzymolysis for 2-3 hours at the temperature of 40-55 ℃, and filtering by a 200-mesh sieve to obtain filtrate which is chicken embryo egg fine slurry; heating water to 40-80 ℃, adding xylitol, sodium carboxymethylcellulose and soluble soybean polysaccharide to dissolve and mix uniformly to obtain a preparation solution; adding the prepared solution into the thin egg pulp, mixing, adding malic acid and rice vinegar, mixing, homogenizing, packaging, and sterilizing to obtain the beverage. In the preparation process, floccules are avoided probably due to incomplete enzymolysis, a thickening agent and an emulsifying agent are added into the filtrate obtained after enzymolysis to stabilize the system and prevent the system from layering, but the product still has the risk of layering and precipitation in the later storage process.
CN 103948111A discloses a nutritional health beverage, which is prepared by mixing, blending, homogenizing, degassing, sterilizing and cooling egg liquid, wild jujube juice, medlar juice, honey, white granulated sugar, spice and the like. In the process, the preparation method of the egg liquid of the chicken embryo comprises the following steps: fresh eggs subjected to fine breeding are selected and placed in an electric heating constant temperature device with the temperature of 37-39 ℃ for incubation, and fertilized eggs are directly beaten into egg liquid after being converted into 8-9 days old incubated chick embryo eggs, namely the chick embryo egg liquid. However, the nutritional health-care beverage and the egg liquid of the chicken embryo have no corresponding debittering and fishy smell removing treatment, and the taste of the product is poor.

Comparative example 1
Comparative example 1 differs from example 2 in that: in the step 3), 0.04% of aspergillus oryzae lipase, 0.1% of papain, 0.06% of trypsin and 0.05% of bromelain are subjected to enzymolysis for 2 hours at the temperature of 50 ℃.
The chick-embryo egg beverage prepared in the comparative example 1 is in a turbid state after being sterilized at high temperature; the chick embryo egg powder obtained in example 2 is brown, and the blended chick embryo egg beverage is in a clear state after being sterilized. The method is mainly characterized in that the egg powder in the comparative example 1 is not sufficiently enzymolyzed, and the compound enzyme added in the step 3) is less, so that the protein and the polypeptide in the egg are not effectively decomposed, the residual protein and the polypeptide in the egg powder are too much and have poor solubility, and the protein and the polymorphism of the prepared beverage are denatured to form precipitates after high-temperature treatment.
Comparative example 2
Comparative example 1 differs from example 2 in that: the perilla juice, ginger powder and black tea powder are not added in the step 1), and ultrasonic treatment is directly carried out; meanwhile, in the step 4), the glucose is not added, and the mixture is directly heated in a water bath at 100 ℃ for 10 min.
The embryonated egg powder obtained in the comparative example 2 has obvious fishy smell and bitter taste, and the prepared embryonated egg beverage has certain fishy smell and bitter taste; the embryonated egg powder obtained in example 2 had a slight fishy smell and no bitterness, and the prepared embryonated egg beverage had no fishy smell and no bitterness. The method is mainly characterized in that a large amount of amino compounds causing fishy and bitter taste are contained in the egg embryo after enzymolysis, although a part of the egg is removed by heating, the egg embryo powder still can generate serious fishy and bitter taste without special treatment, step 1) of comparative example 2 lacks physical fishy smell removal pretreatment, and step 4) does not add glucose and cannot generate ammonia carbonyl reaction, so that a part of the amino compounds generating fishy and bitter taste still remain, and the egg powder and the beverage obtained in comparative example 2 have fishy and bitter taste.
