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...
