  • 在葡萄酒中存在农药是十分关注的问题,由于农药在葡萄栽培中广泛使用。7澄清剂(活性炭、膨润土、polyvinylpolypyrrolidone明胶,鸡蛋清蛋白、明胶、酪蛋白)检查在从白葡萄酒去除农药,富含单一解决方案和混合物的杀虫剂。固相萃取GC-ECD紧随其后进行分析农药残留。有效性降低吸附剂的顺序是:活性炭> 64%卵清蛋白≥23%,明胶22% > PVPP 17%≥16% >膨润土8%酪蛋白。鱼胶除显示,22%在最高允许浓度。澄清剂的类型的影响,农药的化学结构和性质将辛醇和水(分离系数和水溶解度)农药的去除进行了研究。不同的行为表现出每个澄清剂,通过增加疏水性和亲水性的吸附减少农药。通常高于其混合物,从单一的解决方案每个农药的去除,所展现的拮抗和协同效应。

    • 使用三种不同溶剂[50%丙酮水溶液(Ace/w)、50%乙醇水溶液(Eth/w)或50%甲醇水溶液(Meth/w)]和葡萄酒产生残留物(种子、皮和果渣)的提取过程的影响,并对黑比诺[PN]和Pinot meunier [PM]的酚类谱和其提取物的抗流感活性进行确定。与其他溶剂相比,Meth/W提取物中的总酚含量(TPC)最低(P <0.05),但溶剂提取系统对果渣和葡萄皮的TPC没有影响。Pinot meunier果渣提取物对流感病毒A具有1mg/mL浓度的保护作用,而种子和种皮提取物均具有10mg/mL浓度的保护作用。Meth/w提取物显示出比其他提取物更高的抗流感活性。葡萄酒生产残留物提取物的抗流感活性不依赖于TPC。

    • I am very pleased to present the results of the national monitoring programme for pesticide residues in food carried out in 2000 by the Department’s Pesticide Control Service as a service contract to the Food Safety Authority of Ireland. Food safety is of great importance to all involved in the food chain and, through the residue monitoring programme, consumers can be assured that they are not exposed to unacceptable pesticide residue levels and that only authorized pesticides are applied to food crops. I am also pleased to report that the Pesticide Control Laboratory has achieved accreditation from the National Accreditation Board (NAB) of Ireland to the ISO 17025 standard, during 2000, for the analysis of selected pesticide residues in food of plant origin. The accreditation status of the laboratory will be extended to cover additional pesticides and food commodities. This report provides detailed information on the results of the sampling and analysis programmes for residual traces of pesticides in both imported and domestic food.
