摘　　要：将花生果和花生仁在准低温条件下(<20℃)储藏,监测储藏过程中水分含量、发芽率、以及从中提取的花生油的酸价、过氧化值、碘值、维生素E含量的变化。结果表明:在整个储藏过程中,花生仁水分含量保持在4.69%~5.04%之间,花生果水分含量保持在5.11%~6.09%之间;发芽率随着储藏时间的延长有所下降,但储藏10个月后依然维持在90%以上;酸价和过氧化值随着储藏时间的延长而上升,在储藏10个月后花生果和花生仁的酸价分别增至(0.23±0.00)mg/g和(0.36±0.02)mg/g,花生果和花生仁的过氧化值分别增至(0.60±0.02)mmol/kg和(0.64±0.08)mmol/kg;维生素E含量逐渐下降。与常温储藏相比,准低温储藏的花生油脂酸败程度明显降低。说明带壳储藏和准低温储藏能在一定程度上延缓花生品质劣变。The peanut in shell and peanut kernel were stored under quasi low temperature(<20℃),and the changes of moisture content,germination rate,acid value,peroxide value,iodine value and vita-min E content of peanut oil extracted from them were monitored during storage.The results showed that during the whole storage process,the moisture content of peanut kernel remained between 4.69%~5.04%,and that of peanut in shell remained between 5.11%~6.09%.The germination rate de-creased with the extension of storage time,but remained above 90%after 10 months of storage;The acid value and peroxide value increased with the extension of storage time.After 10 months of storage,the acid value of peanut in shell and peanut kernel increased to(0.23±0.00)mg/g and(0.36±0.02)mg/g,re-spectively,and the peroxide value of peanut in shell and peanut kernel increased to(0.60±0.02)mmol/kg and(0.64±0.08)mmol/kg,respectively.Vitamin E content gradually decreased.Compared with normal temperature storage,the rancidity of peanut oil stored at quasi low temperature was significantly reduced.The results showed that shell storage and quasi low temperature storage could delay the deterioration of peanut quality to a certain extent.
