Problems solved by technology

Existing instant bird’s nest products still use the traditional hot water extraction method to extract sialic acid, the extraction rate is low, and too high extraction temperature will also affect the functional properties of sialic acid

Embodiment 1

[0043] The embodiment of the present invention provides a kind of preparation method of freshly stewed bird's nest, and this method comprises the following steps:

[0044] S101. Soak the dried bird's nest, and break up the soaked bird's nest;

[0045] Bird's nest is also a typical high-moisture substance. The water content of the bird's nest itself is low, and the water content is generally not higher than 15%. Therefore, before the bird's nest is stewed and eaten, the dried bird's nest must be fully soaked and washed repeatedly. The bird's nest itself is insoluble in water but swells when it absorbs water. Bird's nest from different origins will have slightly different degrees of water absorption and swelling, and water of different water quality will also affect the degree of swelling of the bird's nest. Normally, the water-absorbing swelling ratio of bird’s nest is 6-8 times at room temperature, and the water content is higher than 80%. After foaming, the swelling degree o...

Embodiment 2

[0106] On the basis of embodiment 1, embodiment 2 of the present invention provides a kind of preparation method of fresh stewed bird's nest, described method comprises the following steps:

[0107] S201. Soak the dried bird's nest, and break up the soaked bird's nest; specifically, cut the corners of the dried bird's nest before soaking, and then soak the hair in pure water at 0-4°C. 6-12 hours.

[0108] S202. Washing, screening, and dehydrating the bird's nest after foaming and breaking up; specifically, cleaning the bird's nest after foaming and breaking up to remove heavy metals and nitrites; using a rotary centrifuge to clean the The final bird's nest is dehydrated, the rotating speed of the rotary centrifuge is 700-1500 rpm, and the dehydration time is 3-8min; the dehydrated bird's nest is screened to remove impurities and divided into glass bottles according to the preset amount.

[0109] S203, inject the juice into the glass bottle and add 4% papain at the same time, ...

Embodiment 3

[0124] On the basis of embodiment 1, embodiment 3 of the present invention provides a kind of preparation method of freshly stewed bird's nest, and described method comprises the following steps:

[0125] S301. Soak the dried bird's nest, and break up the soaked bird's nest; specifically, cut the corners of the dried bird's nest before soaking, and then soak the hair in pure water at 0-4°C. 6-12 hours.

[0126] S302. Washing, screening, dehydrating and bottling the bird's nest after foaming and breaking up; specifically, cleaning the bird's nest after foaming and breaking up to remove heavy metals and nitrite; using a rotary centrifuge to clean the The final bird's nest is dehydrated, the rotating speed of the rotary centrifuge is 700-1500 rpm, and the dehydration time is 3-8min; the dehydrated bird's nest is screened to remove impurities and divided into glass bottles according to the preset amount.

[0127] S303. After injecting the juice into the glass bottle, use 400W mic...

Abstract

The invention discloses a preparation method of freshly stewed bird's nests. The preparation method comprises the following steps: soaking dry bird's nests, and scattering the soaked bird's nests; cleaning the soaked and scattered bird's nests, performing screening, performing dehydrating, and performing bottling; performing heating sterilizing on the bottled bird's nests; and cooling the bottled edible bird's nests after heating sterilizing to 0-4 DEG C for storage and transportation. The sialic acid extraction rate is improved by optimizing technological parameters of an existing bird's nest stewing processing method, such as the liquid-material ratio, the heating temperature, the heating time and the pH value. The sialic acid extraction is promoted through natural papain, the extraction rate of the sialic acid in the bird's nests is further improved through a microwave-assisted enzyme method, and the bird's nest extract does not contain preservatives and additives, is safer and healthier, and gives full play to the nutritional value of the bird's nests.

Description

technical field [0001] The invention relates to the technical field of bird's nest products, in particular to a preparation method of fresh stewed bird's nest. Background technique [0002] The bird's nest is a nest built by the saliva secreted by several swiftlets of the swift family (Apedidae) or mixed with their down feathers. It is mainly produced in Southeast Asian countries such as Malaysia, Indonesia, Thailand, and Myanmar, as well as the coastal areas of Fujian and Guangdong in my country. Bird's nest has always been popular among the people for its precious medicinal materials and delicacies. As a high-end tonic for both medicine and food, it is deeply loved by consumers at home and abroad. Bird's nest is rich in natural nutrients such as mucin, protein, sialic acid, calcium, phosphorus and vitamins. Among them, mucin is a component of cell protoplasm, connective tissue and some enzymes, which is very important to the physiological functions of the human body; sia...
