不同包装材料和密闭储藏处理对油菜籽品质的影响

Effects of different packaging materials and airtight storage on storage quality of rapeseeds

采用阻隔性能不同的编织袋、聚乙烯膜袋、复合膜袋和铝箔膜袋密闭储藏油菜籽,并分别进行不同处理(干燥储藏剂、二氧化碳充气、脱氧剂),研究不同处理方式对油菜籽主要品质酸价和过氧化值的影响。结果表明:油菜籽品质和包装材料的透氧率、透水率关系密切,铝箔膜袋和复合膜袋是比较理想的密闭储藏包装材料;干燥储藏剂的使用能显著提高储藏期种子发芽率,但对酸价和过氧化值无显著影响;对比不同密闭储藏处理方式,脱氧剂处理油菜籽品质保持最好,二氧化碳次之。研究获得了适合油菜籽密闭储藏的方式和包装材料,为油菜产区油菜籽的长期储藏提供了有效的技术和方法,也为其他富含油脂蛋白原料的储藏提供参考。

Woven bags,polyethylene film bags,composite film bags,and aluminum foil film bags were used to store rapeseeds airtightly,and the effects of using desiccants,carbon dioxide aeration,and deoxidizers on the acid value and peroxide value of rapeseeds were investigated.The results showed that the quality of rapeseed was closely related to the oxygen permeability and water permeability of packaging materials,among which,aluminum foil film bag and composite film bag were ideal packaging materials for airtight storage.Although desiccants had no obvious effects on acid and peroxide values of rapeseeds,they maintained the seed germination rate during storage extremely significant.Moreover,it was found that deoxidizers had the best preservative effects,followed by carbon dioxide.This study found suitable airtight storage methods and packing materials for rapeseeds,which provides effective techniques and methods for long-term storage of rapeseeds and also provides a reference for storing other raw materials that are rich in oil and protein.
