Example Embodiment

[0039] Embodiment: a preparation method of fucoidan beer, comprising two steps of separation and extraction from kelp, decolorization, purification of fucoidan and preparation of fucoidan beer:

[0040] The steps of separating, extracting, decolorizing and purifying fucoidan from kelp are as follows:

[0041] 1) Separation and extraction of fucoidan from kelp:

[0042] After the dried kelp was de-silted and dried into kelp algae powder, it was leached in hot water at 90°C for 11 hours. The amount of water was 30ml / g. 1 / 2 of the volume, precipitated with 60% ethanol at a final concentration, washed twice with anhydrous ether and acetone, and finally vacuum-dried to obtain laminarin;

[0043] 2) Decolorization of fucoidan:

[0044] Adjust pH to 8.8 with concentrated ammonia or NaOH solution, add H dropwise below 30°C 2 O2 , the dosage is 0.4 times that of the polysaccharide solution, and the temperature is kept for 40 minutes; the decolorized kelp is filtered, washed with wat...

Example Embodiment

[0058] Example 2: Separation, extraction, decolorization and purification of fucoidan, the steps are as follows:

[0059] 1) Separation and extraction from kelp

[0060] After the dried kelp was de-silted and dried into kelp algae powder, it was extracted with hot water at 80°C for 11 hours, and the water volume was 30ml / g. 1 / 2, precipitating with ethanol with a final concentration of 60%, washing twice with anhydrous ether and acetone, and finally vacuum drying to obtain crude laminarin.

[0061] The rest are the same as in Example 1

[0062] Example 3: Separation, extraction, decolorization and purification of fucoidan, the steps are as follows:

[0063] After the dried kelp was de-silted and dried into kelp algae powder, it was extracted with hot water at 90°C for 11 hours, and the water volume was 30ml / g. 1 / 2, precipitating with ethanol with a final concentration of 65%, washing twice with anhydrous ether and acetone, then decolorizing and purifying, and finally vacuum drying to obtain laminarin.

[0064] The rest are the same as in Example 1.

Abstract

The invention relates to a preparation method for fucoidin beer, belonging to the beer production technical field. Fucoidin is leached with hot water from kelp, precipitated with ethanol, washed with absolute ethyl ether and acetone, decolored and purified with CaCl2 to obtain the purer fucosan sulfuric acid ester. The preparation method comprises the following steps of malt juice preparation, boiling and hop addition, fermentation and fucoidin addition and so on, wherein the malt juice is prepared by saccharification, filtering, boiling, hop addition, precipitation and cooling through feeding the crushed raw materials with a ratio of the raw materials to water of 1 to between 3 and 4. The malt juice is subject to primary fermentation, post fermentation, post storage, fucoidin addition and other steps, and the fucoidin beer with high nutrient value, stable property and good taste is obtained. With the preparation method, the application value of the kelp is fully developed, the fucoidin and the beer are perfectly combined, thereby the health care value of the fucoidin can be well used.

Description

technical field [0001] The invention relates to a method for preparing fucoidan beer, which belongs to the technical field of beer production technology. Background technique [0002] Fucoidan, namely sulfated fucans, is a water-soluble sulfated heteropolysaccharide commonly found in brown algae and some echinoderms. The content of fucoidan in kelp is generally 0.3%-1.5%. The existence of fucoidan is closely related to plant parts. The content of kelp leaves is higher than that of stems, the content of leaves gradually increases from the base to the tip, and the content of leaves is higher than that in the middle. [0003] The molecular structure of fucoidan sulfate is as follows: [0004] [0005] Fucoidan sulfate is mainly based on C 1、2 , few with C 1、3 and C 1、4 Linked α-L-fucose-4-sulfate is polymerized, accompanied by a small amount of galactose, xylose, glucuronic acid, arabinose, protein and metal ions such as potassium, sodium, calcium and magnesium. A typic...
