干海参水发前后质量指标分析

Quality Index Analysis of Dried Sea Cucumber Before and After Rehydration

分析比较干海参水发前后质量指标的差异,为评估水发后食用态海参的营养成分和健康风险提供数据参考。采集市售50份干海参样品,对水发前后海参的营养指标(蛋白质、盐分、海参多糖、海参皂苷)、兽药残留指标(氯霉素、孔雀石绿、呋喃唑酮代谢物、呋喃西林代谢物、呋喃妥因代谢物、呋喃它酮代谢物、恩诺沙星)和重金属指标(铅、镉、无机砷、甲基汞)进行测定。结果表明:50份干海参样品水发后营养指标的含量有所损失,盐分损失最大;有3份干海参样品水发前兽药残留含量超过参考值,检出项目为呋喃唑酮代谢物、呋喃西林代谢物和恩诺沙星,但水发后,均达到参考值水平以下;重金属污染物指标水发前后均未检出问题样品。干海参水发前后质量指标含量存在差异,水发后食用态的海参营养指标含量有所降低,但营养价值仍很高;兽药残留和重金属指标随着发制过程而大幅减少,健康风险较低。

It is to analyze and compare the quality index of dried sea cucumber before and after rehydration,and to provide reference for evaluating the nutritional composition and health risk of edible sea cucumber.About 50 samples of dried sea cucumber sold in the market were collected.The nutritional indexes(protein,salt,sea cucumber polysaccharide and sea cucumber saponin),veterinary drug residues(chloramphenicol,malachite green,furazolidone metabolite,furacillin metabolites,nitrofurantoin metabolite,furantoin metabolite and enrofloxacin)and heavy metal indicators(lead,cadmium,inorganic arsenic,methylmercury)of sea cucumber were determined before and after rehydration.The results showed that the nutritional index content of 50 dry sea cucumber samples was lost after soaking,and the salt loss was the largest;The content of veterinary drug residues in 3 dry sea cucumber samples exceeded the reference value before soaking,but they all reached below the reference value level after soaking.The detected items were furazolidone metabolite,furacilin metabolite and enrofloxacin;No heavy metal indexes were detected before and after rehydration.The quality index of dried sea cucumber was different before and after rehydration.When the dried sea cucumber was soaked to edible state,the content of nutritional index was reduced,but the nutritional value was still very high;The residue of veterinary drugs and heavy metal indicators significantly decreased with the development process,and the health risk was low.
