Description

Preparation method of ready-to-drink chicken protein beverage
Technical Field
The invention belongs to the technical field of food, and particularly relates to a preparation method of a ready-to-drink chicken protein beverage.
Background
The chicken protein is a high-quality protein source, and has the characteristics of easy absorption and high conversion rate for human body supplementary protein. The protein liquid is separated from eggs and is widely applied to food, but the product for directly drinking the protein liquid is not available in the market. Some fitness personnel manually isolate the food from the existing ones for the purpose of protein supplementation, and also prove to be a market demand. The chicken protein forms gel after denaturation due to low denaturation temperature, is difficult to prepare liquid ready-to-drink products, and is compatible with other proteins to prepare composite products, wherein the amount of the chicken protein cannot be increased.
For example, the patent CN102406207B of the invention granted in china discloses a whole egg powder liquid egg beverage, which comprises the following components: the adding amount of the egg powder is as follows: 3% -6%; the addition amount of the protease is 0.2 to 0.8 percent; the sugar content is 4-7 percent, and the acid content is 0.75-0.05 percent; the addition amount of the composite stabilizer is 0.25-1%. The invention has the beneficial effects that: through a scientific formula, the whole egg powder can be fully stirred and emulsified, so that the product has unique taste and strong egg fragrance, and the egg powder can be changed into a liquid beverage, thereby being beneficial to ensuring the health of eaters; the process is reasonable, the beneficial components of the eggs are better preserved, the preparation is simple, the cost is low, and the egg yolk is suitable for being used by the broad masses. The preparation method has simple process and easy operation, and is suitable for industrial production; the obtained product has high protein content and balanced nutrition, and is suitable for various people.
For another example, the patent CN106942381B of the invention granted by china discloses a preparation method of an egg polypeptide beverage, the adopted composite enzymolysis is used for preparing the egg polypeptide beverage, the content of free amino acids in the egg liquid is improved, and simultaneously, the cholesterol content in the egg liquid and the allergenicity of eggs can be effectively reduced, so that the utilization rate and the biological value of the eggs are improved; the method of the invention can reduce the foaming property of the egg liquid and improve the stability of the egg liquid, and has practical and popularization values.
However, when the protein solution is directly subjected to protease enzymolysis, the enzymolysis reaction efficiency is extremely low because the protein solution is mainly globulin, and bitterness is generated due to improper control after hydrolysis. If the problems of good efficiency and degree of hydrolysis are not completely solved, the process has no production value. Therefore, the technical problem to be solved by those skilled in the art is still how to provide a ready-to-drink chicken protein beverage which has no bitter taste, high protein liquid content and can withstand UHT sterilization without coagulation.
Disclosure of Invention
Based on the reasons, the invention provides a preparation method of a ready-to-drink chicken protein beverage, and the prepared ready-to-drink chicken protein beverage has no bitter taste, high protein liquid content and can withstand UHT sterilization without coagulation. Specifically, in order to achieve the purpose of the present invention, the following technical solutions are proposed:
one aspect of the invention relates to a method for preparing a ready-to-drink chicken protein beverage, comprising the steps of:

(4) After the enzyme reaction is finished, enzyme deactivation is carried out through heat treatment, the heating temperature is 80-85 ℃, the time is 5-8 minutes, and then cooling is carried out for standby;
(5) Adding 3-5wt% of sucrose, 0.05-0.2wt% of citric acid and 0.05-0.2wt% of lactic acid sugar into the protein solution, then adding 0.2-0.5wt% of stabilizer xanthan gum, stirring uniformly, and then sterilizing at 100-120 ℃ for 15-30 seconds;
(6) And (4) aseptically filling to obtain a finished product, wherein the finished product of the ready-to-drink chicken protein beverage is similar to yoghourt in appearance and flavor and can be directly drunk.
The preparation method of the invention has the technical key points that at least:
(1) The heating temperature range of the chicken protein can ensure that the protein is denatured and incompletely coagulated, and the efficiency of the action of the protease after the denaturation is high;
(2) By controlling the type (acid protease), the dosage, the hydrolysis and the temperature and time of the enzyme, the instant chicken protein beverage does not generate obvious bitter taste;
(3) According to the invention, good taste can be realized only by adding a small amount of sucrose (generally, the content of sucrose in the beverage is more than 6 wt%);
(4) The invention only needs a small amount of stabilizer, and ensures enough stability while endowing taste.
In a preferred embodiment of the present invention, the ready-to-drink chicken protein beverage has a chicken protein content of 90% or more.
In a preferred embodiment of the invention, the proteolytic enzyme is used in an amount of 1-5U/100 protein solution.

In a preferred embodiment of the invention, the washed eggs are cracked by a continuous egg-breaking machine, and the separation of egg white and yolk is simultaneously carried out, so as to obtain egg white liquid.
Advantageous effects
The invention develops a new process and a new product for denaturing protein liquid and a new heating technology by adopting biotechnology aiming at the requirement of supplementing high-quality protein. By utilizing heat denaturation and protease treatment, the protein is denatured and simultaneously the fluidity is preserved by heating, so that effective enzyme degradation can be carried out, and the chicken protein can keep the fluidity under the UHT sterilization condition, thereby preparing the chicken protein product which can be stored at normal temperature and can be directly drunk. Can be used for people with protein supplement requirements, such as fitness people, outdoor activity people and the like to supplement the egg roll, and is convenient to carry and eat. The chicken protein liquid is subjected to pre-denaturation by a microwave heater, then is modified and blended by an enzyme method, and is sterilized at ultrahigh temperature to obtain a direct drinking chicken protein liquid product which can be stored at normal temperature and has the chicken protein content higher than 90%.
