Problems solved by technology

But for many white-collar and gold-collar mothers-to-be, it takes a lot of time and energy to buy dried bird's nest and cook it by themselves, and it is inconvenient to eat. Therefore, instant bird's nest has become a more convenient and convenient choice for them to carry with them. , Enjoy anytime
[0003] At present, the sialic acid content of ready-to-eat bird’s nest products for pregnant women on the market ranges from 10 mg to 150 mg. Especially for pregnant women who have a large demand for sialic acid, it is difficult to meet their nutritional needs, and some are obtained by adding artificial synthesis or microbial fermentation. Sialic acid, there is a certain food safety risk

preparation example Construction

[0044] The present invention also claims a preparation method of high sialic acid instant bird's nest product, comprising the following steps:

[0045] (1) Soaking and sorting of bird’s nest: Soak dried bird’s nest in 10-30 times purified water for 0.5-2.0 hours, remove impurities, clean and set aside;

[0046] (2) Stewing and refining: Weigh 10%-40% of the bird’s nest after soaking and picking in step (1), weigh and add 10-25 times of purified water, put it in a sandwich pot and stew for 0.5-1.0h , and then finely grind the stewed bird's nest through a colloid mill for 3 to 7 minutes, and repeat twice to obtain bird's nest pulp;

[0047] (3) Biological enzymatic hydrolysis: Pour the bird’s nest slurry into the enzymatic hydrolysis tank, add 0.02-0.07% neutral protease and trypsin (mass ratio 1:1) for enzymatic hydrolysis of bird’s nest, start stirring and control the stirring rate to 30- 80r / min, enzymatic hydrolysis at 50°C-60°C for 0.5-1.0h, after the end of enzymolysis, h...

Embodiment 1

[0054] A preparation method of high sialic acid instant bird's nest product, comprising the steps of:

[0055] Required raw material formula, by mass percentage: bird's nest 5.0%, bird's nest for enzymolysis 5.0%, rock sugar 3%, enzyme preparation (neutral protease and trypsin, 0.07% by bird's nest amount), purified water; concrete preparation is as follows :

[0056] 1) Soaking and sorting: Soak the bird’s nest in 10 times purified water for 0.5 hours to remove impurities and clean it for later use;

[0057] 2) Stewing: Calculate the amount of bird’s nest used for enzymatic hydrolysis (amount of enzymatically hydrolyzed bird’s nest=proportion of enzymatically hydrolyzed bird’s nest*total soaked bird’s nest), weigh it, add 20 times of purified water, put it in a sandwich pot and stew for 1 hour ;

[0058] 3) Refining: finely grind the stewed bird's nest for 5 minutes with a colloidal grinder, and repeat twice to obtain bird's nest pulp;

[0059] 4) Enzymolysis: Pour the bir...

Abstract

The invention discloses an instant bird's-nest product with high sialic acid content and sterilization and preparation methods thereof and belongs to the technical field of food processing. A nutrition essence in partial bird's-nest is extracted through a biological enzymatic hydrolysis technology and then added to a product, so that the content of the sialic acid in the bird's-nest product reaches 500 mg / 100g and the solid content reaches 75% or more; and the edible taste of the instant bird's-nest product is improved through controlling process parameters of refining, enzymatic hydrolysis, homogenization, filtration, concentration and the like. Every part in the product is evenly heated by adopting a three-stage sterilization process; and the time is precisely controlled and heat precisely penetrates to the central part of the product during high-temperature and short-time sterilization treatment on the product. Target bacteria are rapidly killed, so that the quality safety of the product is ensured. Meanwhile, macromolecular protein nutrients in the bird's-nest are decomposed into a relatively small molecular state through the enzymatic hydrolysis technology, so that digestion and absorption are facilitated; the nutrition requirements of a pregnant woman consumer group are completely met; and the instant bird's-nest product is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a high-sialic acid instant bird's nest product and its sterilization and preparation methods. Background technique [0002] As a natural nourishing product, bird's nest has always been loved by female consumers, especially pregnant women. Bird's nest has the functions of nourishing yin and moistening dryness, nourishing lung deficiency, and nourishing qi. In particular, the sialic acid in bird's nest can effectively promote Intellectual development of fetuses and infants, so instant bird's nest products with high sialic acid content are very popular among pregnant women. Eating bird's nest during pregnancy can not only supplement the nutrition needed during pregnancy, but also the bird's nest acid in bird's nest can also improve the body's immunity and promote the development of infants and young children. Role in brain and nervous system development. But for...
