苹果汁中拟除虫菊酯类和氨基甲酸酯类农药辐照降解（Degradation of Pyrethroids and Carbamate Pesticides in Apple Juice by Irradiation）
苹果汁 农药残留 降解
2009/5/22
采用60Co-γ射线辐照对苹果汁中4种拟除虫菊酯类农药和3种氨基甲酸酯类农药进行了降解，研究了不同辐照剂量对苹果汁中农药的降解效果和苹果汁主要理化指标的影响。结果表明，60Co-γ射线辐照对两类农药的降解作用都很显著：辐照剂量为9kGy时菊酯类农药的降解率达到最大，其中，氯菊酯65.72%、氟氯氰菊酯94.14%、氟氰戊菊酯72.41%和溴氰菊酯67.84%；辐照剂量为7?kGy时氨基甲酸酯类农药...

irradiation viscometry dose-effect starch pepper
2008/11/21
Dose-effect relationship was studied in the rheoviscometric behaviour of geliffied suspensions of irradiated corn starch and black pepper, as the variation of the apparent viscosity and the shear stre...
Effect of g irradiation and storage time on the ascorbic acid concentration in onion bulbs (Allium cepa L.)
onions ionisation ascorbic acid storage
2008/11/21
The stability of ascorbic acid (AA) of irradiated onion bulbs stored at 4 and 20 oC was studied. Gamma ionisation at 0.10; 0.15 and 0.30 kGy causes losses of 10, 13 and 20% of AA content, respectively...
