Preparation method of convenient instant bird's nest and product thereof

Abstract

The invention discloses a preparation method of convenient instant bird's nest and a product thereof. The method comprises the following steps: pretreating bird's nest; adding into a glutamine transaminase water solution for soaking; draining the material, immersing the drained bird's nest shreds into water; and adding acid to adjust the pH value of the system to 0-5, soaking at 30-100 DEG C for 20-600 minutes, draining the material, cleaning with clean water at normal temperature, fishing out the bird's nest shreds, draining, drying, mixing with water or sweet water, sub-packaging, sealing, sterilizing in a high-temperature pressure cooker, cooling, inspecting and packaging to obtain the convenient instant bird's nest. After the bird's nest shreds are treated by glutamine transaminase, the bird's nest shreds are subjected to enzymolysis; the protein denaturation further enables the internal structure of the bird's nest shreds to be more compact, and the protein denaturation and the bird's nest shreds have a synergistic effect, so that the thermal stability during high-temperature sterilization is improved, the bird's nest shreds are insoluble during high-temperature sterilizationand later storage, and the phenomenon of water melting of the bird's nest shreds is avoided.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a preparation method of a convenient instant bird's nest and a product thereof. Background technique [0002] Bird's nest is a nest formed by the condensation of saliva or down feathers of swiftlets of the Swiftlet family Swiftlet family and the same species. It is a precious traditional Chinese medicine, which has the functions of nourishing yin and moistening dryness, nourishing the middle and nourishing qi, nourishing the stomach and spleen, and stopping bleeding due to trauma. , Resolving phlegm and relieving cough and other unique curative effects. Bird's nest is rich in mucin, protein, sialic acid, calcium, phosphorus and vitamins A, D, E, K and other natural nutrients. 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; sialic acid, also known...

AI Technical Summary

Problems solved by technology

[0004] However, bird's nest silk is not resistant to high temperature, and bird's nest silk is easily dissolved into water during high temperature sterilization

The dissolution of the bird's nest silk not only reduces the solid content in the product, but also loses the taste and texture of the bird's nest. At the same time, the disappearance of the bird's nest silk will also cause consumers to doubt the authenticity of the product.

In order to improve the stability of the internal tissue structure of bird's nest silk, patent CN105325797A discloses a method for preparing bird's nest soft cans using steaming and segmental sterilization technology. The method includes soaking, ultrasonic cleaning, cleaning and drying, steaming, and moisture regain , liquid filling, soft can sealing, back pressure segmental sterilization, cooling, finished product inspection, storage and other technological processes, although the problems of bird’s nest silk softening and dehydration have been solved, the technological process is relatively cumbersome. Therefore, this There is an urgent need for a simple and convenient instant bird's nest preparation method in the field
