Embodiment 1

[0024] The invention provides a method for reducing the loss of sialic acid in the bird's nest processing process, which comprises the following steps:

[0025] Using the same batch of bird’s nests with the same specifications and raw material sialic acid content of 9.9%, they were divided into two groups, A and B, for the experiment:

[0026] Group A: first place the bird’s nest to be treated in a hot air circulation drying oven at 50°C for drying, and control the water content below 8%; then, open the steamer, wait until the water boils, and lay the bird’s nest to be treated flat In the tray, put it into the steaming cabinet, start timing, and steam for 15 minutes with steam; then, stop the heating of the steaming cabinet, take the bird’s nest to be treated out of the steaming cabinet, put it in a bucket containing ice-water mixture, and put the bucket into the predetermined In the ice room with a temperature of 0-4°C, keep the water temperature at 0-4°C, soak for 8 hours at...

Embodiment 2

[0031] Using the same batch of bird’s nests with the same specifications and raw material sialic acid content of 7.5%, they were divided into two groups, A and B, for the experiment:

[0032] Group A: first place the bird’s nest to be treated in a hot air circulation drying oven at 60°C for drying, and control the water content below 8%; then, open the steaming cabinet, wait until the water boils, and lay the bird’s nest to be treated flat In the tray, put it into the steaming cabinet, start timing, and steam for 30 minutes with steam; then, stop the heating of the steaming cabinet, take the bird’s nest to be treated out of the steaming cabinet, put it in a bucket containing ice-water mixture, and put the bucket into the predetermined In an ice room with a temperature of 4-8°C, keep the water temperature at 4-8°C, soak for 6 hours at a low temperature, and control the foaming rate to make the taste better.

[0033] Then, the bucket containing the bird's nest to be processed is...

Embodiment 3

[0037] Using the same batch of bird’s nests with the same specifications and raw material sialic acid content of 12.3%, they were divided into two groups, A and B, for the experiment:

[0038] Group A: first place the bird’s nest to be treated in a hot air circulation drying oven at 40°C for drying, and control the water content below 8%; then, open the steamer, wait until the water boils, and spread the bird’s nest to be treated In the tray, put it into the steaming cabinet, start timing, and steam for 40 minutes with steam; then, stop heating the steaming cabinet, take the bird’s nest to be treated out of the steaming cabinet, put it in a bucket containing ice-water mixture, and put the bucket into the predetermined In an ice room with a temperature of 8-12°C, keep the water at a temperature of 8-12°C, soak for 4 hours at a low temperature, and control the foaming rate to make the taste better.

[0039] Then, the bucket containing the bird's nest to be processed is taken out...

Abstract

The invention discloses a method for reducing sialic acid loss in a bird's nest treatment process, and belongs to the field of health-care foods. The method comprises the following steps: firstly, steaming bird's nest to be treated by steam; then, soaking the steamed bird's nest by using an ice water mixture for a set time; and then, carrying out feather picking treatment on the soaked bird's nestto obtain a finished product. According to the invention, the bird's nest protein is denatured by high-temperature denaturation before feather picking, so that sialic acid combined with the protein in the bird's nest is retained. The sialic acid in the bird's nest does not exist in a monomer form and is combined with the glycoprotein in the bird's nest. When the protein is not easy to dissolve inwater after being denatured, the sialic acid in the bird's nest is not easy to dissolve in water, so that the content of the sialic acid is retained in the wet picking process. Therefore, the sialicacid in the bird's nest is completely retained in the feather picking treatment and the later product processing.

Description

technical field [0001] The invention relates to the field of health food, in particular to a method for reducing sialic acid loss during bird's nest processing. Background technique [0002] Bird's nest was first recorded in "Materia Medica Fengyuan". Its nature and flavor are sweet and flat, and it returns to the heart, lungs and kidneys. Hemoptysis, hematemesis, chronic dysentery, chronic malaria, choking, nausea and other diseases are widely spread and used among the people for their precious medicinal materials and delicious delicacies. They are high-level health products that are suitable for medicine and diet. Bird's nest contains a large amount of mucin, glycoprotein, sialic acid, trace elements, epidermal growth factor and other biologically active ingredients. [0003] Sialic acid has the functions of anti-virus, promoting cell division and improving immunity. Therefore, the content of sialic acid in bird's nest products directly determines the nutritional value o...
