新疆马铃薯种薯综合保鲜技术的研究

Study on the Storage Technique of Xinjiang Seed Potatoes

摘要:

对新疆马铃薯种薯进行了贮藏研究，确定了最佳贮藏条件，并对贮藏过程中的干物质、淀粉、还原糖、蛋白质和Vc含量变化进行了分析。结果表明：最佳贮藏条件是低温3~5 ℃+套袋处理，在此条件下贮藏的马铃薯失重率、腐烂率和发芽率均最低。贮藏过程中还原糖含量的变化始终遵循着淀粉-还原糖-淀粉的可逆动态平衡；随着贮藏时间的延长，马铃薯Vc含量逐渐降低；蛋白质、干物质含量变化不明显；淀粉含量呈先下降，到了末期有所回升的趋势。

Abstract:

In this paper, the storage conditions of Xinjiang seed potatoes were studied and the contents of dry matter, starch, protein, reducing sugar and Vc in seed potatoes during storage were analysized. The results showed that the lowest weight loss rate, rotting rate and burgeon rate were obtained by putting the seed potatoes into bags and storing them at 3~5 ℃. The content of Vc gradually decreased with increasing the storage time, and the protein and dry matter contents showed little changes. The content of starch decreased at the initial storage period, and then slightly increased at the last storage period. The change of reducing sugar content was in accordance with the reversible starch-reducing sugar-starch dynamic balance.
