Description

一种降低扇贝毒素的改良剂
技术领域
本发明涉及一种降低扇贝毒素的改良剂。
背景技术
扇贝毒素(pectenotoxins,PTXs)是一类聚醚大环内酯结构的脂溶性海洋生物毒素,是由海洋甲藻中的鳍藻属Dinophysis spp.的几个种产生的毒素,1984年首次从日本陆奥(Mutsu)湾的的养殖扇贝日本虾夷扇贝Patinopecten yessoensis的消化腺中发现鉴定。具有很高(小鼠致死剂量实验数据存在冲突,因此无法给出结论性数值)的小鼠腹腔注射致死毒性。自从被发现以来,其所发现的地理区域不断扩大,我国亦有发现。
大多存在于微藻和贝类中。
由于PTXs类毒素在不同贝中的结构分布、以及不同组分结构的毒理机制存在巨大差异,对于不同的地区、不同的贝类,其潜在风险是非常不同的。在葡萄牙贝中,绝大部分PTX-2转化为PTX-2sa,就目前的研究结果显示这一过程导致毒性减小,就PTXs毒素而言,食用贝类可以认为是安全的。新西兰绿壳贻贝(Perna canaliculus)和蓝贻贝(Mytilusgalloprovincialis)快速转化PTX-2为细胞毒性更小的PTX-2sa,就这2种贝的食用安全而言,风险不大。日本扇贝(P. yessoensis)转化PTX-2为同样具有肝毒性的PTX-1、PTX-3和PTX-6,就这一类毒素来说,日本扇贝的食用风险就相当大。
虾夷扇贝,是近些年来贝类水产品的重要品种,其闭壳肌蛋白质构成特殊,据分析每百克含有63.7克蛋白质、3克脂肪、醣类15克、钙47毫克、磷886毫克、铁2.9毫克。虾夷扇贝含有丰富的不饱和脂肪酸EPA和DHA。
因此,如何降低扇贝毒素是增加该类食品安全性的关键因素之一。
发明内容
本发明针对上述现有技术的不足,提供了一种降低扇贝毒素的改良剂,通过大蒜素为主要组分的改良溶液,降低PTX-2含量,并抑制其转化为PTX-1或PTX-3的过程。
本发明的技术方案是:
一种降低扇贝毒素的改良剂,其特征在于它包括以下重量份组分:
大蒜素 10-100份;
红曲红 10-50份;
水500-1000份;
乙醇100-1000份。
发明人在实践中探求多种降低扇贝毒素的方法,发现扇贝毒素与大蒜素以及红曲红特定比例组成的溶液中处理后,可降低扇贝毒素10倍以上,其作用原理目前并不十分清楚,可能是PTX-2与大蒜素以及红曲红形成某种络合物引起。
优化地,所述改良剂的重量份组分为:
大蒜素 10-100份;
红曲红 10-50份;
β环糊精 20-200份;
水500-1000份;
乙醇100-1000份。
大蒜素,英文名Allicion,分子式为C6H10OS2
红曲红,英文名Monascus red,别名红曲色素,其水溶液最大吸收峰波长为490±2nm,熔点165-190℃,主要活性物质为Monascidin A;Ankalactone;红曲色素,橙色素和几丁质酶。
