Abstract
The present invention discloses a method for removing inorganic arsenic in kelp. The method comprises the following steps: 1, soaking dry kelp in ultrapure water for 3-8h, then rinsing the kelp with ultra-pure water for 3-5 times; 2, putting the kelp in an edible acetic acid solution with a concentration of 1-10 g/L and carrying out ultrasonic treatment, wherein the ultrasonic frequency is set to 25-100kHz, the processing time is 5-20min, and the edible acetic acid solution temperature is 15-35 DEG C; and 3, rinsing the kelp with ultra-pure water and carrying out drying. According to the method for removing inorganic arsenic in the kelp, operation is simple, the inorganic arsenic removal rate can reach more than 96%, and the food safety of the kelp can be ensured.
Description
Technical field
The invention belongs to food processing technology field, be specifically related to a kind of method removing sea-tangle inorganic arsenic.
Background technology
In recent years, economy development of coastal area is rapid, and cause a large amount of discharges of industrial pollution, to such an extent as to the water quality of inshore declines year by year, offshore pollution scope constantly expands.And algal culture base concentrates on offshore sea waters, its sea area, local is based on heavy metal pollution, and heavy metal pollution is again based on virose heavy metals such as mercury, chromium, cadmium, lead.And as the arsenic of nonmetalloid, due to its source with endanger similar with heavy metal, within the scope usually also being listed in heavy metal.If heavy metal element is unprocessed directly enter river, lake or ocean, or enters in soil, they can make these rivers, lake, ocean and soil be polluted because not being biodegradable.Under the biological magnification of food chain, the ground enrichment of thousands of hundred times, heavy metal, finally enters human body, gently then causes strange illness, heavy then cause death.There is strong interaction in heavy metal energy and protein and enzyme etc. in human body, make them lose activity, also can accumulate in some organ of human body and cause slow poisoning, the poisoning that heavy metals exceeding standard like this causes is too numerous to enumerate.Sea-tangle has because of it favor that higher edibility and medical value are subject to people day by day, but due to marine pollution day by day serious, marine product heavy metals exceeding standard phenomenon happens occasionally, and the adsorption capacity of sea-tangle heavy metal is higher, often occurs heavy metals exceeding standard phenomenon.In the last few years, the report that market upper part sea-tangle arsenic exceeds standard also once was had.Mandatory national standards GB19643-2005 " algae goods sanitary standard " and GB2762-2005 " pollutants in food limitation " standard regulation: algal product inorganic arsenic limitation≤1.5mg/kg.
Summary of the invention
Technical problem to be solved by this invention is: the problem exceeded standard for sea-tangle inorganic arsenic, provides a kind of method removing sea-tangle inorganic arsenic.
For realizing the object of the present invention, be achieved by the following technical solutions: a kind of method removing sea-tangle inorganic arsenic, comprises the following steps successively:
2. dry sea-tangle is put into after ultra-pure water soaks 3-8h, separately gets ultra-pure water rinsing 3-5 time;
2. the sea-tangle through previous step process being put into concentration is that the alimentary acetic acid solution of 1-10g/L carries out ultrasonic process, and ultrasonic frequency is set as 25-100kHz, and the processing time is 5-20min, and alimentary acetic acid solution temperature is 15-35 DEG C;
3. the sea-tangle through previous step process is used ultra-pure water rinsing, and dry.
Preferably: described step 1. in dry sea-tangle soak time in ultra-pure water be 6h, described step 2. in the concentration of alimentary acetic acid solution be 5g/L, ultrasonic frequency is set as 35kHz, and the processing time is 15min, and alimentary acetic acid solution temperature maintains 25 DEG C.
Compared with prior art, the invention has the beneficial effects as follows: sea-tangle arsenic removing method of the present invention is simple to operate, and inorganic arsenic removal efficiency can reach more than 96%, ensure that the edible safety of sea-tangle.The interpolation of alimentary acetic acid serves the effect of low acidified solution, improves the removal efficiency of inorganic arsenic, and can not have any impact to the nutritional labeling of sea-tangle, local flavor, and through repeatedly to rinse and the volatile person's character of tool determines that alimentary acetic acid also can not remain.
Detailed description of the invention
Commercially, through detecting, abio-arsenic residues is 3.11 ± 0.21 mg/kg to the dry sea-tangle used in following examples, exceeds standard more than one times.
