Embodiment 1

[0025] Add 8g of urease to 8L cod skin collagen peptide solution with 32% Brix, and adjust the pH of the solution to 4.5. After incubating at 40°C for 15min, add 40g of activated carbon, and decolorize and deodorize at 40°C for 15min. Utilize dish centrifuge at 5000rpm under centrifugal 20min to remove gac, then utilize anion exchange resin to its decolorization deodorization 15min at 20 DEG C, the solution that obtains is slowly added 0.4L dehydrated alcohol under stirring, static at 20 DEG C Place it for 60 minutes; finally, the decolorized and deodorized collagen peptide solution is spray-dried at 150° C. at the air inlet temperature and 70° C. at the air outlet temperature by using a spray dryer to obtain 1.8 kg with a moisture content of 6% (w / w ) about collagen peptide powder.

Embodiment 2

[0027] Add 30g urease to the 6L shark bone collagen peptide solution that is 38% in Brix, and adjust the pH of the solution to 6.0. After incubating at 30°C for 60min, add 90g of activated carbon, and decolorize and deodorize after 60min at 30°C. Utilize disc centrifuge at 6000rpm under centrifugal 40min to remove activated carbon, utilize macroporous adsorption resin to decolorize and deodorize 30min to it at 40 DEG C then, the solution obtained slowly adds 0.9L dehydrated alcohol under stirring, at 40 DEG C Leave standstill 15min; The collagen peptide solution of the depigmentation decolouring that obtains at last utilizes spray drier, is 190 DEG C at air inlet temperature, carries out spray drying under 100 DEG C of air outlet temperature, can obtain 1.7kg moisture content and be 6.5% ( w / w) about collagen peptide powder.

Embodiment 3

[0029] Add 25g urease to 10L shark bone collagen peptide solution with 40% Brix, and adjust the pH of the solution to 5.0, after incubating at 35°C for 30min, add 100g of activated carbon, and decolorize and deodorize after 30min at 35°C. Utilize disc centrifuge to remove gac at 5500rpm by centrifugation for 30min, then utilize chelating resin to decolorize and deodorize it for 60min at 35°C, and slowly add 1.0L absolute ethanol to the solution obtained under stirring, statically at 30°C Put 30min; Finally, the collagen peptide solution of depigmentation decolorization that will obtain utilizes spray drier, is 170 DEG C at air inlet temperature, carries out spray drying under 80 DEG C of air outlet temperature, can obtain 3.0kg moisture content and be 6.0% (w / w) about collagen peptide powder.

[0030] The color of the collagen peptide samples before and after decolorization and deodorization was measured by a colorimeter, and the results are shown in Table 1. It can be s...

Abstract

The invention discloses a decolorization and deodorization method of deep-sea fish collagen peptide. The technical process includes adjusting the pH of the collagen peptide solution prepared from deep-sea fish skin or fish bone to weak acidity, using urease for deamination, decolorization and decolorization with activated carbon and resin After the fishy smell, use alcohol to further remove the fishy smell, and finally use spray drying to prepare a colorless and odorless collagen peptide. The invention has a simple process, a mild treatment process, and does not destroy the biological activity of the collagen peptide; the prepared collagen peptide is white and has no fishy smell, and can be widely used in industries such as health food, biomedicine, and cosmetics.

Description

technical field [0001] The invention relates to the field of decolorization and deodorization of collagen peptides, in particular to a production method for decolorization and deodorization of deep-sea fish collagen peptides. Background technique [0002] With the deterioration of the environment, the acceleration of the pace of life and the improvement of health care awareness, people's attention to health gradually extends from disease to sub-health state, so the extraction and preparation of active ingredients with health care functions are increasingly valued by consumers. On the other hand, with the development of science and technology and the improvement of people's living standards, people's understanding of the active ingredients in marine resources is deepening, and the demand for active substances from marine biological sources is increasing. According to reports, collagen peptides are easy to digest and absorb, have many physiological functions such as protecting...
