Embodiment 1

[0029] 1. Fresh long oysters are removed from the impurities, washed, opened the shells to take the meat, and drained. Take long oyster meat and process it repeatedly 5 times in a tissue grinder at 10,000-12,000 r / min, each time for 3 minutes, to obtain long oyster pulp, weigh the mass and measure the volume.

[0030] 2. Add 4 times the amount of ethyl acetate according to the volume of long oyster pulp, stir at 300r / min for 120min, and centrifuge at 4800r / min for 30min to remove ethyl acetate to obtain long oyster pulp.

[0031] 3. Add 5 times of water to the long oyster pulp and stir evenly. Stir continuously at 300r / min for 10min to form a cloudy liquid. After heating to 55°C, keep the temperature constant.

[0032] 4. Add 3000 activity units of neutral protease per gram to the turbid liquid at a constant temperature of 55°C, according to the mass of long oyster pulp, and enzymatically hydrolyze with continuous stirring at 300r / min for 180min.

[0033] 5. After the enzymat...

Embodiment 2

[0043]1. Take out and melt the long oyster meat frozen at -18°C, wash it, add water to boil for 3 minutes, let cool to room temperature, and drain. Then, it was repeatedly processed in a tissue grinder at 10,000-12,000 r / min for 5 times, each time for 3 minutes, to obtain long oyster pulp, which was weighed and volume measured.

[0044] 2. The rest are the same as Steps 2-13 of Example 1.

Abstract

The invention relates to a preparation method of crassostrea gigas meat antifatigue nutrient solution. Crassostrea gigas meat is smashed into pulp, ethyl acetate is added and stirred for removing fishy smell, centrifugation is carried out, ethyl acetate is removed, crassostrea gigas meat pulp is collected, water is added, stirring to be uniform is carried out, heating is carried out, neutral protease is added according to the mass of crassostrea gigas for enzymolysis, the neutral protease is activated, papain is added according to the mass of crassostrea gigas for enzymolysis, the papain is activated, then bromelain is added according to the mass of crassostrea gigas for enzymolysis, and then the bromelain is activated, and cooling to room temperature is carried out. Centrifugation is carried out, water solution is collected, vacuum concentration is carried out, sterile water is used for diluting to appropriate concentration, sugar, citric acid and edible salt are added, and mixing to be uniform is carried out, thus obtaining the product. The invention adopts advanced technology, process is simple and feasible, especially three-enzyme composite hydrolysis is adopted, hydrolyzing degree of protein of crassostrea gigas meat can be obviously improved, more amino acid and small peptide can be produced, and product quality is obviously improved. Animal experiment shows that antifatigue effect is good.

Description

technical field [0001] The invention belongs to a preparation method of long oyster meat anti-fatigue functional nutrient solution. Background technique [0002] As our country integrates with the international community, people's pace of life is getting faster and faster, and everyone is busy: students are exhausted by heavy learning tasks almost every day, and young and middle-aged people are exhausted for work and life. . Only by quickly eliminating fatigue and recovering physical fitness can people complete the hard work and heavy learning tasks in the future. Consuming products with anti-fatigue effects is an effective way to achieve the above goals. [0003] At present, many domestic scholars have conducted experiments on the anti-fatigue effect of peptides. As reported in the second issue of "Food Science and Technology" in 2010, Professor Ji Hongwu from Guangdong Ocean University adjusted the oyster pulp to pH 7.0, the concentration ratio of enzyme and substrate w...
