飲料中香豆素、β-杜衡精及總氫氰酸之調查

SURVEY ON SPECIAL FLAVORING AGENTS: COUMARIN, β-ASAR9NE AND TOTAL HYDROCYANIC ACID IN THE BEVERAGE

民國七十五年十月至七十六年六月間抽購全省北、中、南、東四地區之市售飲料。採用氣相層析方法分析飲料中特殊香料成分之香豆素及β-杜衡精含量，並以吡啶（Pyridine）呈色，可見分光光譜比色分析總氫氰酸含量。香豆素及β-杜衡精之回收率分別為93.5%及91.6%。最低偵測界限三者分別為O.2mg/kg、0.05mg/kg 及0.05mg/kg。在總共56件檢體）中除檢出國產飲料一件含有香豆素0.75mg/kg外（佔1.8%，β-杜衡精及總氫氰酸含量皆在最低偵測界限以下，以上檢驗結果皆符合我國食品添加物使用範圍及用量標準，香豆素、β-杜衡精及總氫氰酸分別為2mg/kg，0.1mg/kg及1mg/kg之限量規定。

The investigation of coumarin, β-asarone and total hydrocyanic acid in marketed drinks were performed from October 1986 to June 1987 in Taiwan. Cotents of coumarin and β- asarone in drinks were analyzed by gas chromatography. Total hydrocyanic acid were analyzed by colorimetric method and measured the absorbance by spectrophotometer. The recovery and detectable level of coumarin, β- asarone were respectively 93.5%. 91.6% and 0.2mg/kg. 0.05mg/kg. The detectable level of total hydrocyanic acid was 0.05 mg/kg. The results showed that only one of 56 samples contained coumarin 0.75mg/kg, the amounts ofβ-asarone and total hydrocyanic acid were all under the detectable level. All samples didn't violate the legal allowance amounts 2mg/kg for coumarin, 0.1mg/kg forβ- asarone and 1 mg/kg for total hydrocyanic acid.
