CO_2充气储藏对葵花籽营养品质的影响

Effect of storage conditions on nutritional quality of sunflower seeds

为了保持葵花籽储藏中营养品质,采用CO_2充气包装,研究CO_2浓度分别为10%,50%,100%及自然空气对照组在储藏8个月的过程中葵花籽水分含量、蛋白质、脂肪、碘值变化的影响。结果表明,充气组储藏条件下,葵花籽水分含量变化为25%左右,有利于葵花籽储藏;纯CO_2组蛋白质总含量变化为0.9%,而10%CO_2、50%CO_2为16%左右;充气组葵花籽仁含油量变化基本维持在6.91%~7.38%;碘值变化维持在117.11~141.91g/100g。因此,采用纯CO_2储藏葵花籽的营养品质在整个储藏期几乎不变。

Changes in moisture,protein,fat,iodine and value of sunflower seeds were investigated during storage under different carbon dioxide concentration conditions respectively,10%,50%,100%and natural air control in the process of storage for eight months sunflower seed moisture content of raw material in order to keep the sunflower seeds stored in nutritional quality,Results showed that air group storage conditions,sunflower seed moisture content change was approximately 25%,which was beneficial to sunflower seed storage;Pure CO_2 group total protein content was 0.9%,while that of 10% CO_2,50% CO_2 was approximately 16%;Inflatable group of sunflower seed kernel oil content change basic maintained at 6.91%~7.38%;Iodine value change was between 117.11 ~141.91g/100 g.Therefore,the use of pure CO_2 storage sunflower seeds of nutritional quality in the storage period is almost the same.
