用电离辐照处理农产品可引起多种生理变化,蔗糖含量的增加就是其中之一。然而蔗糖含量与辐照剂量之间的关系尚不清楚。作者研究了这种关系并发现:经高剂量辐照后,蔗糖含量一旦增加,在长期的贮存过程中就不会下降。这种积累发生在辐照马铃薯、甘薯和板栗 Treatment of agricultural products with ionizing radiation can cause a variety of physiological changes, one of which is the increase in sucrose content. However, the relationship between sucrose content and irradiation dose is unclear. The authors studied this relationship and found that sucrose content, once irradiated at high doses, did not decrease during long-term storage. This accumulation occurs in irradiated potatoes, sweet potatoes and chestnuts
