Abstract
The invention is to prepare polysaccharide complex without heavy metal residual by complexing marine polysaccharide and tantalum. The polysaccharide metal complex has a good depriving action for cadmium and lead residual of bivalve, can be used as feed additive for reduce heavy metal residual and special agent for depriving metal for fish and shellfish clarification or temporary curture, which has significance for keeping the quality safty of aquatic product.
Description
Technical field
The present invention utilizes marine polysaccharide and metallic element complexing, prepares a kind of polysaccharide complex with removing heavy-metal residual.This polysaccharide complex has and removes cadmium in the fresh and alive bivalve shellfish, plumbous residual action, is having wide practical use aspect the fresh and living aquatic products quality and safety ensureing.
Background technology
China is shellfish culture big country, and ultimate production ranks the first in the world for years.China's shellfish ultimate production was 1,162 ten thousand tons in 2004, and wherein marine shellfish accounts for more than 40% of sea-food total amount more than 95%.Shellfish has been one of fishery products of liking of people.But because the shellfish poor mobility, the regional relative fixed of living is lived near the sea area area, river mouth mostly, and is easily contaminated so often be subjected to the invasion and attack of sanitary sewage and industrial sewage etc. and influence.The Bivalvia economic shellfish belongs to filter food simultaneously, and it is in filter food erbium material biology, and also with in the objectionable impurities suction bodies such as chemical pollutant in the seawater, accumulation ability is extremely strong.What is more important people be again usually with eat something rare or half a lifetime ripe eating serve as main also not remove internal organ, therefore, in case environment is subjected to heavy metal contamination, the potential safety hazard maximum of shellfish.
Along with the industrialized process of China, heavy metal elements such as cadmium, lead have entered environment in many ways, the safety of food have been constituted bigger hidden danger, especially fishery products thus.Many units are investigated heavy metal content in the fishery products over nearly 10 years, and heavy metal content such as cadmium, the lead phenomenon that exceeds standard is serious in the shellfish body, and wherein cadmium is the most serious, does not remove and still there is effective means at present.Therefore, it is residual or effectively to take off cadmium be the task of top priority in the bivalve shellfish body how to reduce heavy metal elements such as cadmium, lead, the prepared polyose metal complexes of the present invention is to bivalve shellfish cadmium, the plumbous residual effect that removes preferably that has, can be used as breeding feed additive and fish, the shellfish purification with minimizing heavy-metal residual or support the special-purpose agent of demetalization temporarily, this is significant to the quality safety that ensures China's fishery products.
Summary of the invention
The present invention utilizes marine polysaccharide and metallic element to prepare the marine polysaccharide metal complexes, adds this title complex in shellfish purification or foster temporarily process, and cadmium, the decline of lead element residual rate reach about 50% after 5 days.This title complex cost is low, and is easy to operate simple, is easy to apply.
Technical process is as follows: zinc, magnesium, iron, calcium are dissolved in the acetum, fully add marine polysaccharide behind the mixing, the reaction some hrs is treated to dissolve fully the back and is regulated pH, promptly gets the marine polysaccharide metal complexes.With this title complex add to fish, shellfish support temporarily or purify waste water in or add the erbium material to, after continuing to support temporarily or purifying 5 days, can reach the heavy-metal residual effects such as cadmium, lead in the shellfish body that remove.
Embodiment
Get mixture any or 4 kinds of metal-salts in a certain amount of zinc, magnesium, iron, the calcium salt and join in 0.2%～0.9% the acetum, the add-on of metal-salt is with respect to 0.01%～0.2% of acetum; Fully add chitosan or algal polysaccharide behind the mixing, the add-on of chitosan or algal polysaccharide is with respect to 0.1%～4% of acetum, and 20～45 ℃ were reacted 5～18 hours down, after treating to dissolve fully, regulated pH to 3.0～7.0, promptly obtained polyose metal complexes.
Example one: get sal epsom 0.06g, add among 0.5% the acetum 100ml, fully stirring and evenly mixing adds the 0.4g algal polysaccharide, and 35 ℃ of anti-shadows 12 hours after treating to dissolve fully, are regulated pH to 5.0, promptly obtain the algal polysaccharide magnesium complex.Add this title complex to shellfish and support temporarily in the water, after continuing to purify 5 days, can reach the heavy-metal residual effects such as cadmium, lead in the shellfish body that remove.
Example two: get sal epsom 0.04g, iron(ic) chloride 0.02g, among the acetum 100ml of adding 0.5%, abundant stirring and evenly mixing, add the 0.4g algal polysaccharide, 25 ℃ were reacted 16 hours, after treating to dissolve fully, regulate pH to 4.0, promptly obtain algal polysaccharide magnesium, iron complex.Add this title complex to shellfish and support temporarily in the water, after continuing to purify 5 days, can reach the heavy-metal residual effects such as cadmium, lead in the shellfish body that remove.
Example three: get sal epsom 0.02g, iron(ic) chloride 0.02g, calcium acetate 0.02g, among the acetum 100ml of adding 0.5%, abundant stirring and evenly mixing, add the 0.4g chitosan, 25 ℃ were reacted 16 hours, after treating to dissolve fully, regulate pH to 4.5, promptly obtain the title complex of chitosan magnesium, iron, calcium.Add this title complex to shellfish and support temporarily in the water, after continuing to purify 5 days, can reach the heavy-metal residual effects such as cadmium, lead in the shellfish body that remove.
