应用富马酸二甲酯作为防霉剂对大米及月饼进行试验研究。在不同使用量、不同存放期分别用气相色谱法测定其残留量。大米存放至60天时残留量下降至0.00～5.62mg/kg,月饼存放至45天残留量达135.05～705.52mg/kg,残留量 t 值为3.366,P<0.01,有非常显著性差异。残留量与油脂含量有密切的关系。
The application of dimethyl fumarate as preservative to rice and moon cakes were studied. In different usage, different storage period were determined by gas chromatography residue. Residues of rice stored until 60 days decreased to 0.00 ~ 5.62mg / kg, moon cake stored until 45 days residual amount of 135.05 ~ 705.52mg / kg, residual t value of 3.366, P <0.01, there is a very significant difference. Residues and oil content are closely related.
