Problems solved by technology

Among them, enzymatic hydrolysis and hydrolysis may not only destroy amino acids with poor stability and sialic acid in the form of glycoproteins, but also introduce additional chemical substances, and these methods will lose some nutrients, resulting in unsatisfactory extraction efficiency

Embodiment 1

[0069] Take bird's nest raw material (Swiftlet Garden, Desaru, Johor, Malaysia) 800g. Remove the feathers and sundries in the bird's nest raw material, and use a grinder to crush the bird's nest or bird's nest into bird's nest powder at room temperature. 680g of fine and clean bird's nest powder were obtained after removing the hair and foreign matter on the bird's nest by suction, filtration and centrifugation. In order to avoid the material from becoming gel due to shear heat, the temperature of the grinder cavity is set at 30°C.

[0070] Put the crushed bird's nest powder into pure water at a weight ratio of 1:20, pass through an ultrasonic vibrator (ultrasonic frequency 40KHz, ultrasonic power 250W), ultrasonically crush for 20 minutes, and heat to 50°C for 6 hours to let the bird's nest powder particles Swell to the optimum, and obtain a total of 14280g of nest slurry GY0-1 for effective extraction.

[0071] Take out GY0-1, add purified water at a weight ratio of 1:4, c...

Embodiment 2

[0081] Get 800g of bird's nest raw material (Swiftlet Garden, Desaru Biological Valley, Johor, Malaysia), and process it according to the method of Example 1 to obtain 710g of bird's nest powder. Put the crushed bird's nest powder into distilled water with a weight ratio of 1:30, pass through an ultrasonic vibrator (ultrasonic frequency 40KHz, ultrasonic power 250W), after ultrasonic crushing for 20 minutes, soak at 40°C for 8 hours to allow the bird's nest powder particles to expand to optimal. A total of 22010g of bird's nest slurry GY0-2 was obtained for effective extraction.

[0082] Take out GY0-2, add it to distilled water at a weight ratio of 1:3, continue to stir at a speed of 300rpm, and heat at 80°C for 5 hours to loosen the nutrients in the bird's nest, and extract GY1-2 to obtain a total of 88040g.

[0083] Put the extract GY1-2 into a stirring container, heat at 40°C and stir at a speed of 200rpm for 30 minutes, then let it stand for 4 hours to drain the lower se...

Embodiment 3

[0092] Get 800g of bird's nest raw material (Swiftlet Garden, Desaru Biological Valley, Johor, Malaysia), and obtain 701g of bird's nest powder according to the method in Example 1. Put the pulverized bird's nest powder into the clean water with a weight ratio of 1:40 and soak for 10 hours, through an auxiliary ultrasonic vibrator (ultrasonic frequency 40KHz, ultrasonic power 250W), after ultrasonic crushing for 20 minutes, it is better heated to 40 ℃ let the bird's nest powder granules expand to the best. A total of 28741g of bird's nest slurry GY0-3, which has the maximum expansion effect of bird's nest powder particles, is waiting for effective extraction.

[0093] Take out GYO-3, add distilled water at a weight ratio of 1:2, continue stirring at a speed of 200rpm, and heat at 75°C for 6 hours to loosen the nutrients in the bird's nest, and extract GY1-3 to obtain a total of 42840g.

[0094] Put the extract GY1-3 into a stirring container, heat at 40°C and stir at a speed ...

Abstract

The invention relates to a cubilose extraction method, a cubilose extract and a cubilose product. The method comprises the following steps: B, soaking clean cubilose powder to obtain cubilose pulp; C,adding water, accounting for 1-5 times the weight of the cubilose pulp, into the cubilose pulp, and conducting continuous stirring for 3-8 hours at a speed of 200-1000 rpm at a temperature of 70-120DEG C to obtain first extracted liquid; D, uniformly stirring the first extracted liquid at a reduced temperature of 30-40 DEG C, carrying out standing, removing first lower-layer liquid containing precipitates after impurities are precipitated, and taking out a supernatant as second extract liquid; E, continuing to uniform stirring residual liquid in the step D at a temperature of 30-40 DEG C, carrying out standing, and discharging second lower-layer liquid containing precipitates after further impurity precipitation to obtain third extracted liquid; and F, combining the second extracted liquid and the third extracted liquid to obtain the liquid cubilose extract. The method is mild, does not use extra chemicals, and better preserves nutritional ingredients in cubilose; low-molecular-weight peptide in the obtained extract accounts for 45 wt% or above, so absorption is facilitated; and meanwhile, an extraction rate is high and can reach 90 wt% or above.

Description

technical field [0001] The present invention relates to a method of extracting from bird's nest and various extracts obtained by said method. Background technique [0002] Our country has a long tradition of eating bird's nest for nourishment. The record about bird's nest first appeared in "Quannan Magazine" written by Chen Maoren in the Jiajing period of Ming Dynasty in 1537. The efficacy of bird's nest was first recorded in "Ben Jing Feng Yuan" written by Zhang Lu, a famous doctor in Qing Dynasty. [0003] More than half of the ingredients in bird's nest are proteins, and a considerable proportion are water-soluble proteins, including proteins that promote the growth of human tissue, 18 kinds of amino acids that are necessary and conditionally necessary for the human body, and 8 essential amino acids. Sialic acid in bird's nest, also known as "N-acetylneuraminic acid (NeuAc)" of sialic acid, is an acetyl derivative of the amino sugar neuraminic acid. Sialic acid has bee...
