摘要
分析白砂糖包装情况(内袋折叠、破损)对其仓储过程中潮包、结块、变红等质量问题的影响。基于连续5个榨季12家企业3250包仓储白砂糖的抽检数据,运用t检验等统计方法,分析白砂糖包装情况(内袋折叠、破损)与仓储过程中潮包、结块、白砂糖变红等问题的关联性,以及变红白砂糖仓储前后质量指标(蔗糖分、还原糖分、干燥失重)的变化。结果显示,结块与潮包、白砂糖变红与潮包、内袋破损与内袋折叠、潮包与内袋破损、内袋破损与结块间互呈显著相关(P<0.05);内袋折叠对潮包存在显著影响(P<0.05),但反之不成立。相对于一级白砂糖标准,仓储变红白砂糖干燥失重超标了6.14倍,蔗糖分下降了1.31 g/100g,还原糖分超标了3.60倍。研究结果可为优化包装工艺、完善仓储管理、制定针对性养护措施提供相关依据。
This study analyzed the impact of packaging conditions(inner bag folding,damage)on quality issues such as damp packages,caking,and red discoloration during the storage process of white granulated sugar.This study was based on the sampling inspection data of 3250 packages of warehouse-stored white granulated sugar from 12 enterprises across five consecutive crushing seasons.Statistical methods such as t-tests were employed to analyze the correlations between white granulated sugar packaging conditions(inner bag folding,damage)and issues during warehousing,including damp packages,caking,and red discoloration of white granulated sugar.Additionally,changes in quality indicators(sucrose content,reducing sugar content,loss on drying)of red-discolored white granulated sugar before and after warehousing were investigated.The results showed significant correlations(P<0.05)between caking and damp packages,red discoloration of white granulated sugar and damp packages,inner bag damage and inner bag folding,damp packages and inner bag damage,as well as inner bag damage and caking.Significant effects(P<0.05)were observed from inner bag folding on damp packages,whereas the reverse effects were not significant.Compared to the standard for first grade white granulated sugar,the loss on drying of stored red discoloration of white granulated sugar exceeded the standard by 6.14 times,the sucrose content decreased by 1.31 g/100g,and the reducing sugar content exceeded the standard by 3.60 times.This study provides a scientific basis for optimizing packaging processes,improving warehouse management,and formulating targeted maintenance measures.
