Embodiment 1

[0021] (1) After crushing the dried bird’s nest, pass it through a 80-mesh sieve, add 20 times its weight in water and soak for 12 hours, change the water every 3 hours during this period, and then wash it with water for 3 times, then add water to prepare bird’s nest with a mass concentration of 1%. liquid, simmer for 30 minutes in water;

[0022] (2) Cool the stewed bird's nest liquid to 40°C, add 0.1mol / L NaHCO 3 The pH value of the solution was adjusted to 8, and the enzyme activity was added to 2×10 5 U / g of alkaline protease, its addition is 0.03% of the dry bird's nest weight, partially enzymolyzed for 30 minutes, until the degree of hydrolysis of the enzymolyzed solution is 5%, immerse in boiling water to kill the enzyme for 3 minutes;

[0023] (3) Cool the enzymolyzed solution after deactivation to 5°C, put it into a vacuum beater, beat at a low speed of 3,000 rpm for 2 minutes at 5°C and a vacuum of 0.06 MPa, and then use 10,000 Turn / min high-speed whipping for 2 mi...

Embodiment 2

[0027] (1) After crushing the dried bird’s nest, pass it through a 80-mesh sieve, add water 20 times its weight and soak for 12 hours, change the water every 3 hours during this period, and then wash it with water for 3 times, then add water to prepare bird’s nest with a mass concentration of 3%. liquid, simmer for 30 minutes in water;

[0028] (2) Cool the stewed bird's nest liquid to 50°C, add 0.1mol / L NaHCO 3 The pH value of the solution was adjusted to 8, and the enzyme activity was added to 2×10 5 U / g of alkaline protease, its addition is 0.04% of the dry bird's nest weight, partial enzymolysis for 60 minutes, until the degree of hydrolysis of the enzymatic solution is 10%, immerse in boiling water to kill the enzyme for 3 minutes;

[0029] (3) Cool the enzymatic hydrolysis solution after deactivation to 15°C, put it into a vacuum beater, beat at a low speed of 5000 rpm for 1min at 15°C and a vacuum of 0.08MPa, and then use 12000 Turn / min high-speed whipping for 1min; ...

Embodiment 3

[0033] (1) After crushing the dried bird’s nest, pass it through a 80-mesh sieve, add water 20 times its weight and soak for 12 hours, change the water every 3 hours during this period, and then wash it with water for 3 times, then add water to make bird’s nest with a mass concentration of 2%. liquid, simmer for 30 minutes in water;

[0034] (2) Cool the stewed bird's nest liquid to 60°C, add 0.1mol / L NaHCO 3 The pH value of the solution was adjusted to 8, and the enzyme activity was added to 2×10 5 U / g of alkaline protease, its addition is 0.05% of the dry bird's nest weight, partially enzymolyzed for 90min, until the degree of hydrolysis of the enzymolyzed solution is 15%, immerse in boiling water to kill the enzyme for 3min;

[0035] (3) Cool the enzymolysis solution after deactivation to 10°C, put it into a vacuum beater, beat at a low speed of 4,000 rpm for 2 minutes at 10°C and a vacuum of 0.07 MPa, and then use 11,000 Turn / min high-speed whipping for 2 minutes;

Abstract

The invention discloses an integrated defoaming method of a bird's nest protein fluid. A bird's nest fluid obtained after bird's nest is stewed with water is firstly subjected to pH regulation, then,partial enzymolysis is performed, and vacuum high-speed and low-speed stirring and high-temperature and low-temperature defoaming are performed circularly three times after enzyme deactivation treatment. A partial enzymolysis technology is adopted, so that the stability of bird's nest protein foam is notably reduced, foam inhibition and defoaming of the bird's nest protein fluid are facilitated;in combination with a vacuum high-speed and low-speed stirring and foam inhibition technology and a high-temperature and low-temperature defoaming technology, the technical problems of unstable product quality, loss of bird's nest protein and difficulty in can sealing and sterilization caused by high probability of bubbling in the processing process of the bird's nest protein fluid are solved. Themethod is simple to operate, no chemical defoaming agents are added, the defoaming effect is good, the product quality is high and a new way is provided for development of new products of bird's nest.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to an integrated defoaming method for bird's nest protein liquid. Background technique [0002] Bird's nest is rich in protein, polysaccharides, lipids, trace elements and sialic acid, etc. It has the functions of nourishing yin and moistening dryness, nourishing the middle and replenishing qi, nourishing the stomach and spleen, reducing phlegm and relieving cough, etc., and has high edible and medicinal value. Bird's nest is easily broken during transportation or processing, resulting in a large amount of broken bird's nest. Broken bird's nest can be used to process bird's nest oral liquid, bird's nest polypeptide, bird's nest beverage, canned bird's nest and remodeled bird's nest and other products. The protein content in bird's nest accounts for 55%-65% of the dry weight of bird's nest. During the preparation of bird's nest protein solution, when the solution...
