【摘要】 利用60Co-γ射线对几种东北特产进行了辐照保鲜贮藏试验研究。结果表明:大米采用复合包装材料及适宜辐照剂量(0.4～0.8kGy)辐照,在常温条件下贮藏1年,无虫蛀现象,且营养成分及感观指标变化不明显;脱水蔬菜(干蘑菇、木耳等)采用复合包装材料及适宜辐照剂量(6～8kGy)辐照可使保藏期达到1年以上。更多还原

【Abstract】 Preservation test was conducted by irradiation of 60Co-γ ray for some kinds of local products of the northeast part. Adoption of compound packaging materials and suitable irradiation dosage between 0.4—0.8 kGy led to no insect-damage or significant change of nutritive composition and sensory indexes after rice had been stored for one year under the condition of normal temperature. Dehydrated vegetables (dry mushroom and agarics etc.) kept in compound packing material sand suitable irradiation dosage between 6—8 kGy could be preserved for more than one year.更多还原
