摘要
以6种类型山药(JJH、SY445、SY453、SY449、XBZ和SY442)为材料,系统比较了其田间农艺性状、营养品质及抗氧化功能。结果表明,在农艺性状方面,JJH长势强、产量最高(60000.00 kg/hm^(2));在营养品质方面,JJH的粗纤维(1.70%)、蛋白质(13.06%)和总糖(6.44%)含量较高,而SY453的直链淀粉含量(27.86%)与直/支(67.54%)最高;在抗氧化功能方面,SY453的·OH自由基清除率最高(96.43%),JJH最低(77.59%);SY449在Fe^(3+)还原力与ABTS自由基清除率(95.44%)方面均表现最强,SY453次之,其余4种类型抗氧化能力相对较低且无显著差异。综合来看,SY449在抗氧化功能方面综合表现优异,而JJH产量高、口感爽脆,更适合鲜食炒制;SY449产量中等、质地绵软,更适宜蒸煮或作为功能食品原料。
Six varieties of Chinese yam(JJH,SY445,SY453,SY449,XBZ,and SY442)were used as materials to systematically compare their field agronomic traits,nutritional quality,and antioxidant functions.The results showed that in terms of agronomic traits,JJH displayed strong growth vigor and the highest yield(60000.00 kg/hm^(2));regarding nutritional quality,JJH contained higher levels of crude fiber(1.70%),protein(13.06%),and total sugar(6.44%),whereas SY453 had the highest amylose content(27.86%)and amylose-to-amylopectin ratio(67.54%);in antioxidant function,SY453 displayed the highest hydroxyl radical scavenging rate(96.43%),while JJH showed the lowest(77.59%);SY449 exhibited the strongest performance in both ferric ion reducing power and ABTS radical scavenging rate(95.44%),followed by SY453,the remaining four varieties demonstrated relatively low antioxidant capacity without significant differences.In summary,SY449 showed superior comprehensive performance in antioxidant function,whereas JJH,with high yield and crisp texture,was more suitable for fresh consumption or stir-frying;SY449,with medium yield and soft texture,was more suitable for steaming,boiling,or as a raw material for functional foods.
