Embodiment 1

[0037] A freeze-dried bird's nest, which is processed through the following steps:

[0038] Impurity removal: Preliminary removal of impurities on fresh bird's nest, picking and removing the bird hair on fresh bird's nest;

[0039] Cleaning, soaking, dehydration: Wash the fresh bird's nest repeatedly with clean water for 3 times, add foaming liquid to 400g of fresh bird's nest after washing, and foam hair. The weight ratio of foaming liquid and fresh bird's nest is 5:1. It is pure water, and the soaking time is 2.5 hours; tear the fresh bird’s nest after soaking according to the texture, filter it with pure water for 3 times, and filter out most of the fluff of the fresh bird’s nest; pick and remove the bird’s hair in the fresh bird’s nest again, Then transfer to a centrifugal dehydrator to dry for 10 minutes;

[0040] Steaming: Steam the dehydrated bird’s nest at 80°C for 4 minutes, cool to 23±2°C to obtain wet bird’s nest;

[0041] Freeze-drying: mold the above-mentioned w...

Embodiment 2

[0043] The freeze-dried bird's nest of embodiment 2 is processed through the following steps:

[0044] Impurity removal: with embodiment 1;

[0045] Cleaning, soaking hair, dehydration: same as Example 1;

[0046] Steaming: with embodiment 1;

[0047] Freeze-drying: mold the above-mentioned wet bird’s nest, freeze at -50°C for 5 hours under an absolute vacuum of 0.5±0.2Pa, freeze at -45°C, -40°C and -35°C for 2 hours, -30°C and -20°C respectively. Freeze at -15°C and -5°C for 1.5 hours respectively, respectively at -15°C and -5°C for 1.5 hours, respectively at 0°C, 5°C and 10°C for 2 hours, and at 20°C for 2 hours, so that the water content in the bird's nest is 3%. Freeze-dried bird's nest.

Embodiment 3

[0049] The freeze-dried bird's nest of embodiment 3 is processed through the following steps:

[0050] Impurity removal: with embodiment 1;

[0051] Cleaning, soaking hair, dehydration: same as Example 1;

[0052] Steaming: steam the dehydrated bird’s nest at 100°C for 2 minutes, cool to 23±2°C to obtain wet bird’s nest;

[0053] Freeze-drying: mold the above-mentioned wet bird’s nest, freeze at -50°C for 6 hours under an absolute vacuum of 0.5±0.2Pa, freeze at -45°C, -40°C and -35°C for 3 hours respectively, and freeze at -30°C and -25°C respectively. Freeze at -15°C and -20°C for 2 hours respectively, freeze at -15°C, -10°C and -5°C for 1.5 hours respectively, dry at 0°C, 5°C and 10°C for 3 hours respectively, and dry at 15°C and 20°C for 2 hours respectively, The water content in the bird's nest is made to be 2.8%, and the freeze-dried bird's nest is obtained.

Abstract

The invention relates to the technical field of freeze-dried food, in particular to freeze-dried cubilose and a processing technology thereof, and the processing technology of the freeze-dried cubilose comprises the following processing steps: cleaning, soaking and dehydrating fresh cubilose; steaming: steaming the dehydrated cubilose at 80-100 DEG C for 2-5 minutes, and cooling the cubilose to 23 + / - 2 DEG C to obtain wet cubilose; freeze-drying: freeze-drying the wet cubilose at -50 to 20 DEG C under the absolute vacuum degree of 0.5 + / - 0.2 Pa until the water content is not greater than 3%, so as to obtain the freeze-dried cubilose. The freeze-dried cubilose processed by the method can be eaten after being soaked in hot water for about 5 minutes before being eaten, is convenient to eat, has relatively high nutritional ingredients, and is fine, smooth, soft, elastic and relatively good in mouth feel.

Description

technical field [0001] The present application relates to the technical field of freeze-dried food, in particular to a freeze-dried bird's nest and its processing technology. Background technique [0002] Bird's nest refers to the nests made of saliva secreted by swifts and swiftlets of the genus Swiftlet, mixed with other substances, also known as agar-jerk, swallow root, and swallow vegetables. The main nutritional component of bird's nest is protein, which contains 1 essential amino acid and 3 conditional essential amino acids. It is also rich in sugars, organic acids and sialic acid, which is a nourishing food. [0003] The cooking method of fresh bird's nest is as follows: take fresh bird's nest, soak in water for 4-5 hours; after soaking, tear the bird's nest, and remove impurities such as fine hair; Submerge the bird's nest in mineral water, stew in water for 25-30 minutes, and serve immediately. The cooked bird's nest has a strong protein taste and is full of elast...
