Problems solved by technology

[0002] In the prior art, the process of producing whey products has two major requirements: on the one hand, in order to retain the active ingredients such as immunoglobulin, lactoferrin, and growth factors in bovine colostrum to the greatest extent, the heat treatment intensity should not be too high; On the one hand, as a kind of food, the microbial index of this kind of product is very important, and the bactericidal effect of the product must be guaranteed, so there is a certain contradiction between the two. In order to solve this contradiction, the relevant products at home and abroad adopt super Low-intensity heat treatment such as high pressure technology, but this technology retains the active ingredients with health care functions such as immunoglobulin in bovine colostrum, and also retains α in dairy products s1 -Casein, β-lactoglobulin and other components that may cause allergies in infants or adults

Embodiment 1

[0014] Place 2.4L of bovine colostrum in a preparative centrifuge at 4000r / min for 20 minutes to remove the milk fat to obtain 2.18L of skimmed bovine early emulsion. Adjust the pH of the skimmed milk to 4.6 with 50% lactic acid. After standing for 20 minutes, place it in the centrifuge. Centrifuge at 4000r / min for 20-30min in the machine to precipitate casein and obtain 1.94L of clear whey liquid. Add 1.0mol / L FeCl 3 Solution, adjust the pH to 3.5~5.0, then continue to add FeCl 3 Solution, until system Fe 3+ The concentration reaches 3.0~8.9mmol / L. During this period, the pH of the system is kept constant between 3.5~5.0 by adding NaOH solution. Let it stand for 1.5h and centrifuge at 4000r / min to remove the precipitate (mainly β-lactoglobulin). Adjust the pH of the clear liquid to 8.0 with 3mol / L NaOH solution, and after standing for 2.5h, centrifuge again at 4000r / min to remove Fe(OH) 3 precipitation. After the supernatant is sterilized by microfiltration through a membrane wit...

Embodiment 2

[0016] Put 6.0L bovine colostrum in a preparative centrifuge at 4000r / min and centrifuge for 25min to remove milk fat to obtain 5.5L skimmed bovine first emulsion. Adjust the skim milk pH to 4.6 with 5%-10% hydrochloric acid, and let it stand for 15-30min Afterwards, place it in a centrifuge at 4000r / min and centrifuge for 20-30min to precipitate casein to obtain 4.95L of clear whey liquid, and then add FeCl to the above-mentioned whey liquid 3 Solution, adjust the pH to 3.5~5.0, then continue to add FeCl 3 Solution, until system Fe 3+ The concentration reached 8.5mmol / L. During the period, the pH of the system was maintained between 3.5 and 5.0 by adding NaOH solution. After standing for 1 to 3 hours, the precipitate of β-lactoglobulin-iron complex was removed by centrifugation at 4000r / min, and the supernatant Adjust the pH of the solution to 8.0~8.5 with 5%~10% NaOH solution. After standing for 2~3h, centrifuge again at 4000r / min to remove Fe(OH) 3 After precipitation, the resu...

Embodiment 3

[0018] Put 6.0L bovine colostrum in a preparative centrifuge at 4000r / min and centrifuge for 20-25min to remove milk fat to obtain skimmed bovine colostrum, then precipitate casein according to the method of Example 1 or 2, and centrifuge to separate whey. Then use hydrochloric acid or lactic acid to adjust the pH of skimmed milk to 4.5, and then add 0.5mol / L FeCl 3 Solution, while adding 10%-15% NaOH solution dropwise to maintain the pH of the system to about pH 4.5, then continue to add FeCl 3 Solution, until system Fe 3+ The concentration reached 8.0mmol / L, stand for 2.5h, centrifuge at 4000r / min to remove the precipitate (mainly β-lactoglobulin), and then use the method of Example 1 or 2, after microfiltration, and the matrix in the prior art Mixing according to a certain ratio, that is, the production process of the innate immune activity and hypoallergenic bovine colostrum whey described in the present invention.

Abstract

It relates to a technique of processing oxen colostrum whey with native immunity active and low sensitization. It comprises, first, the Oxen colostrum should be centrifuged, then casein of Oxen colostrum is removed through a precipitation method, and the pellucid whey liquid is obtained; adding FeCl3 for selectively precipitating ª‰ - lactoglobulin, then adding NaOH, adjusting pH; precipitating, removing excessive Fe3+ in the system; removing bacteria by microfiltering, mixing with the ""matrix"" which has been processed thermally and disinfected at sterile conditions, then obtaining final whey products.

Description

Technical field: [0001] The invention relates to a dairy product, in particular to a whey, in particular to a production process of bovine colostrum whey liquid with natural immune activity and hypoallergenicity. Background technique: [0002] In the prior art, the process of producing whey products has two major requirements: on the one hand, in order to maximize the retention of the immunoglobulin, lactoferrin, growth factor and other active ingredients in the bovine colostrum, the heat treatment intensity should not be too high; On the one hand, as a kind of food, the microbiological indicators of this type of product are very important, and the sterilization effect of the product must be guaranteed. Therefore, there is a certain contradiction between the two. In order to solve this contradiction, related products at home and abroad use ultra High pressure and other heat treatment technology with low intensity, but this technology retains the active ingredients with health fun...
