抑霉唑对葡萄的保鲜效果及其风险评估

Effects and risk assessment of imazalil treatment on grape storage

以葡萄为试材,经抑霉唑处理后冷藏,研究不同施药浓度对葡萄贮藏期间果实品质的影响。结果表明,抑霉唑可较好地保持果实可溶性固形物及可滴定酸含量,抑制葡萄表面霉菌的繁殖,保持果实品质。对贮藏后抑霉唑进行膳食风险评估,无论是250 mg·L^(-1)还是500 mg·L^(-1)浓度抑霉唑处理,急性和慢性膳食风险商均小于100%,属于低风险范围。

In order to explore the effect of imazalil on grape storage,grapes were treated with varied concentrations of imazalil,and then were stored.It was shown that imazalil was favorable to keep grape quality,as soluble solids content and titratable acidity content were not reduced during storage,and it was able to inhibit the propagation of moulds.Chronic dietary intake risk and acute dietary intake risk of imazalil residues in grape were assessed.For either250mg·L-1or500mg·L-1imazalil treatment,both chronic and acute dietary intake risks in grape were below100%,which indicated low pesticide residue risk.
