Embodiment 1

[0019]Select the salted kelp root as the raw material, put it into the air-boiling washing machine for fresh water washing, and the washing water temperature is 15°C, put the seaweed root raw material after air-boiling washing into the drum washing machine for fresh water washing, and the washing water temperature is 15°C , and then put the kelp root raw material washed by the drum into the water tank, rinse with fresh water, the rinse water temperature is 15°C, and cool it for later use. A certain mass of soybean protein isolate powder with a protein content of 43.9% was dissolved in water, the substrate concentration was adjusted to 4% (w / v), stirred evenly, heated to 90°C, kept for 8 min, then cooled to 40°C, and used HCl and NaOH solution adjusted the pH value to 6.5, added alkaline protease to make the enzyme-substrate ratio 4, and continued the enzymatic hydrolysis for 2 hours. After the enzymatic hydrolysis was completed, heat the enzymatic hydrolysis solution to 90°C, k...

Embodiment 2

[0021] Select the salted kelp root as the raw material, put it into the air-boiling washing machine for fresh water washing, and the washing water temperature is 20°C, put the seaweed root raw material after air-boiling washing into the drum washing machine for fresh water washing, and the washing water temperature is 20°C , and then put the kelp root raw material washed by the drum into the water tank, rinse with fresh water, the rinse water temperature is 20°C, and cool for later use. A certain mass of soybean protein isolate powder with a protein content of 43.9% was dissolved in water, the substrate concentration was adjusted to 7% (w / v), stirred evenly, heated to 98°C, kept for 11 min, then cooled to 48°C, and used HCl and NaOH solution adjusted the pH value to 8.5, added alkaline protease to make the enzyme-substrate ratio 6%, and continued the enzymatic hydrolysis for 2.5 hours. Centrifuge at 22.5°C with a centrifuge, take the supernatant, adjust the pH of the supernata...

Embodiment 3

[0023] Select the salted kelp root as the raw material, put it into the air-boiling washing machine for fresh water washing, and the washing water temperature is 23°C, put the seaweed root raw material after air-boiling washing into the drum washing machine for fresh water washing, and the washing water temperature is 23°C , and then put the kelp root raw material washed by the drum into the water tank, rinse with fresh water, the rinse water temperature is 23°C, and cool down for later use. A certain mass of soybean protein isolate powder with a protein content of 43.9% was dissolved in water, the substrate concentration was adjusted to 6% (w / v), stirred evenly, heated to 98°C, kept for 10 min, then cooled to 48°C, and used HCl and NaOH solution adjusted the pH value to 9, added alkaline protease to make the ratio of enzyme to substrate 6.5%, and carried out continuous enzymolysis for 2.7 hours. Centrifuge with a centrifuge at 23°C, take the supernatant, adjust the pH of the ...

Abstract

The invention discloses an instant kelp root and a preparation method thereof. The instant kelp root is prepared through the process of pretreatment, dehydration, shredding, pre-mixing, mixing, packaging, sterilization and obtaining of finished products by adopting salted kelp base as raw material. The problems of inconvenience in eating and poor taste of the existing salted kept products can be solved. Through the pretreatment of the kelp root, the color and luster as well as good quality of the kept root can be kept, meanwhile fishy smell and bitterness can be removed, and the nutritional ingredients of the kelp root can be kept to the greatest degree. The taste of the kelp root can be more perfect by pre-mixing of table salt and apple juice. The delicate flavor of the product can be greatly improved through the synergistic effect of delicious amino acid and flavor nucleotides in a yeast extract. By adding spirulina powder without fishy smell and soybean peptide powder with delicate flavor, the taste of the product can be improved, and meanwhile, synergetic enhancement can e achieved for the nutrition and the health care function of the product. The additional value after the production of the kelp root can be increased while the public diet quality is improved. Through test, the total number of bacteria is about 700-850 / g, and the pathogenic bacteria such as escherichia coli are negative, so that the instant kelp root conforms to the related food quality requirements.

Description

technical field [0001] The invention relates to the preparation of edible seaweed aquatic food products, in particular to an instant kelp root and a preparation method thereof. The salted kelp root is used as a raw material, and it is prepared through pretreatment, dehydration, shredding, pre-blending, blending, packaging, sterilization, and finished products. The process is reasonable, the steps are scientific, and the operation is feasible. Background technique [0002] Kelp, also known as kelp, Jiangbaicai, Lunbu, etc., is a large marine brown algae plant that grows in low-temperature seawater. Studies have shown that kelp is rich in alginic acid, mannitol, crude fiber, vitamins, iodine, potassium, sodium, calcium, magnesium, iron and other ingredients. "Reputation. Studies have found that kelp contains a variety of nutrients, such as rich amino acids and proteins, polysaccharides, lipids, minerals, vitamins and cellulose, especially rich in iodine. Kelp is not only a...
