Embodiment 1

[0067] Making an adsorbent As an adsorbent, see Example 37 of the published patent application CN110191911A for specific manufacturing steps.

Embodiment 11

[0070] Arsenic removal from Antarctic krill oil includes the following steps:

[0071] S1: Shell the Antarctic krill, take the krill meat, and wash it;

[0072] S2: Take the krill meat rinsed in S1, cook at 100°C for about 15 minutes, and centrifuge at 100 rpm for 5 minutes to remove the water;

[0073] S3: drying the steamed Antarctic krill in S2 until its water content is less than 2%, and then pulverizing it with a pulverizer to obtain Antarctic krill powder;

[0074] S4: add absolute ethanol to the Antarctic krill powder in S3 to extract krill oil, stir and extract for about 3 hours, filter to obtain an extract, and rotate the extract at 55°C to obtain krill oil;

[0075] S5: Removal of arsenic:

[0076] (1) Take 30g of krill oil in S4, add absolute ethanol at a weight ratio of 1:5 between krill oil and absolute ethanol, fully dissolve and mix at 65°C, and make an Antarctic krill oil-ethanol mixture ;

[0077] (2) Add 5 g of the adsorbent in Example 1 to the Antarctic ...

Embodiment 12

[0087] The adsorbent in Example 1 was used as the adsorbent to remove arsenic in Antarctic krill oil produced by a company in Shandong.

[0088] The specific application steps are as follows:

[0089] (1) Take 10 g of the Antarctic krill oil, add absolute ethanol at a weight ratio of 1:5 between krill oil and absolute ethanol, fully dissolve and mix at 60° C., and prepare an Antarctic krill oil-ethanol mixture;

[0090] (2) Add 5 g of the adsorbent in the above-mentioned Example 1 to the Antarctic krill oil ethanol mixture, adjust the temperature to 65° C., reflux and stir for 4 hours, and perform arsenic removal treatment;

[0091] (3) Filter and remove the adsorbent in the treatment liquid, put the filtrate into a vacuum drying oven to dry for 24 hours, the temperature is 60°C, the vacuum degree is ≤-0.09MPa, and the antarctic krill oil after decompression distillation is obtained;

[0092] (4) Sampling refers to the second method of the first chapter of GB5009.11-2014 to m...

Abstract

The invention relates to a method for removing heavy metal arsenic in euphausia superba extract. The method comprises the following steps: (1) dispersing euphausia superba peptide powder in water or an acid solution to obtain a mixed solution I; (2) mixing the mixed solution I with an adsorbent, carrying out arsenic removal treatment, and removing the adsorbent to obtain a mixed solution II; (3) desolventizing the mixed solution II to obtain arsenic-removed euphausia superba peptide powder; or (1) dissolving the euphausia superba oil in an organic solvent to obtain a mixed solution A; and (2) mixing the mixed solution A with an adsorbent, and carrying out reflux stirring, rotary evaporation and filtration to obtain the arsenic-removed euphausia superba oil. The content of total arsenic in the euphausia superba extract is greatly reduced, and the safety of the euphausia superba extract is remarkably improved. The method is simple and convenient to operate, the used reagent is easy to obtain, the adsorption effect is excellent, the problem about total arsenic removal in the euphausia superba extract is solved, and the excellent arsenic removal effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of food processing, and relates to a method for removing arsenic from Antarctic krill extracts, and specific adsorbents for obtaining Antarctic krill extracts with low arsenic content (mainly Antarctic krill peptide, Antarctic krill oil) In application, of course, Antarctic krill oil also includes astaxanthin. Background technique [0002] Antarctic krill belongs to the small crustaceans of Crustacea Krill, with extremely high nutritional value. Antarctic krill shrimp meat has high protein content and lipid content. Therefore, for humans, krill is a very ideal Food is regarded as the warehouse of protein resources for the future of human beings. Antarctic krill mainly feeds on plankton and algae, and has the characteristics of enriching trace elements or heavy metals through food chains and other channels. Therefore, Antarctic krill is a biological resource with great potential for development and utilizati...
