Description

Preparation method of dried edible bird's nest

Technical Field

The invention belongs to the technical field of food processing, and particularly relates to a preparation method of dry cubilose.

Background

The bird's nest is formed by condensing saliva of swiftlet of the family delphinidae and saliva of the same genus or mixed saliva of velvet and the like, is a famous and precious traditional Chinese medicine, and has the functions of nourishing yin, moistening dryness, tonifying middle-jiao and Qi, invigorating stomach and spleen, reducing phlegm, relieving cough and the like. The bird's nest contains various enzymes for digesting food, and is also rich in mucin, sialic acid, vitamin A, D, E, K, and the like. Among them, mucin is a component of cellular protoplasm, connective tissue and some enzymes, and is very important for the physiological action of the human body; sialic acid is also called neuraminic acid, and has physiological effects of improving intelligence and memory of infants, resisting senile dementia, resisting recognition and virus, and improving the absorption of vitamins and minerals by intestinal tract.

The traditional method for cleaning the cubilose cannot ensure that the cubilose has better quality. In traditional cognition, the general expansion rate of the edible bird's nest is 6 to 8 times, and the edible bird's nest in a few producing areas can reach 13 to 15 times. And the attainable multiplying power of the cubilose is taken as an important evaluation standard of the quality of the cubilose.

In view of the above, the present invention is directed to a method for preparing dry bird's nest, which is clean and free of impurities, and can obtain a higher expansion effect due to stable colloid of the bird's nest.

The adopted technical scheme is as follows:

a preparation method of dry cubilose sequentially comprises the following steps:

s1, soaking or spraying 20-50% of fresh water into dry cubilose in a raw material state with impurities for multiple times;

s2, the edible bird's nest is given with a nutritional preparation at 40-50 ℃ in a soaking or spraying mode, and the operation time is 2-5 min;

s4, removing impurities from the bird's nest and cleaning;

s5, placing the cleaned cubilose in an equipment environment with the temperature of 10-20 ℃ and the relative humidity of 70% -85% for 12-20 h;

s6, the cubilose is placed in an equipment environment with the temperature of 10-20 ℃ and the relative humidity of 30% -50% for 24-36 h;

s7, the cubilose is placed in an equipment environment with the temperature of 10-20 ℃ and the relative humidity of 70% -85% for 12-20h until drying is completed.

Further, in S2, the nutrient preparation is a liquid monosaccharide or disaccharide solution having a concentration of 50% or more.

The invention has the beneficial effects that:

the preparation method of the dry cubilose can achieve the effect of more stable glue property of the cubilose, obtain better ductility when absorbing the expansion of water, and the average expansion multiple reaches more than 25-45 times.

Detailed Description

The present invention will now be described more fully hereinafter.

The invention relates to a preparation method for processing clean and impurity-free dry cubilose from cubilose raw materials with impurities such as feathers, plant fragments and/or eggshells.

Specifically, the preparation method of the dry cubilose sequentially comprises the following steps:

s1, soaking or spraying 20-50% of fresh water into dry cubilose in a raw material state with impurities for multiple times; but not absorb fresh water in a trickle flow manner. The absorption rate of the fresh water can be well controlled by the modes of soaking and spraying for many times, and the absorption rate of the fresh water is not easy to control and absorb by the mode of leaching. The absorbed fresh water aims to ensure that the cubilose can be primarily puffed and can be primarily cleaned at the same time of puffing.

S2, the edible bird's nest is given with a nutritional preparation at 40-50 ℃ in a soaking or spraying mode, and the operation time is 2-5 min; the nutritional preparation can be liquid monosaccharide or disaccharide solution with concentration of above 50%. Wherein the concentration is a value obtained by dividing the mass of the monosaccharide or disaccharide of the solute by the mass of the aqueous sugar solution.

S3, keeping the cubilose in a high-humidity closed environment with water separation and relative humidity of more than 90%, keeping the environment temperature at 40-55 ℃, and operating for 20-40 min; the purpose of S2 and S3 is to use the ferment of the bird 'S nest itself to provide the required nutrients and temperature for reaction, so as to achieve the purpose of making the colloid of the bird' S nest more stable. Wherein, the dehydration means the soaking with dehydrated water.

S4, removing impurities from the bird's nest and cleaning; cleaning may be performed by, but is not limited to, manual methods such as manually removing impurities such as egg shells, feathers, plant debris, and the like, and removing impurities such as fine hair with the aid of tweezers.

S5, placing the cleaned cubilose in an equipment environment with the temperature of 10-20 ℃ and the relative humidity of 70% -85% for 12-20 h; the bird's nest dries gradually and slowly at higher relative humidity.

S6, the cubilose is placed in an equipment environment with the temperature of 10-20 ℃ and the relative humidity of 30% -50% for 24-36 h; the bird's nest was dried at a lower relative humidity.

S7, the cubilose is placed in an equipment environment with the temperature of 10-20 ℃ and the relative humidity of 70% -85%, and the drying time is generally 12-20 hours until the drying is finished. Therefore, the expansion effect with high multiplying power can be obtained on the premise of obtaining the clean and impurity-free cubilose. S5-S7 is to control the drying process of the cubilose colloid to be slow and keep the maximum elasticity without damaging colloid molecules.

The preparation method of the dry cubilose can achieve the effect of more stable glue property of the cubilose, obtain better ductility when absorbing the expansion of water, and the average expansion multiple reaches more than 25-45 times. The high expansion ratio can be reflected in economic benefit in two aspects that the cost of raw materials of products related to the cubilose is more easily absorbed by eaters.

The above-listed detailed description is only a specific description of a possible embodiment of the present invention, and they are not intended to limit the scope of the present invention, and equivalent embodiments or modifications made without departing from the technical spirit of the present invention should be included in the scope of the present invention.
