| 中文摘要: |
| 试验对香蕉后熟过程中处于转色期、商品期和麻点期的香蕉采用折射仪法测定其可溶性固形物含量，针对前处理所涉及的三种常用取汁方法（恒温水浴加热、中速离心分离和单层滤纸过滤）的试验效果进行比对。结果表明，在准确度方面，中速离心分离和单层滤纸过滤方法测定的结果较为准确；在精确度方面，中速离心分离方法测定的结果最为稳定；综合各方面因素，中速离心分离是最精准快捷的浆汁制取方法，其测定结果具有良好的重复性和稳定性。基于该方法测定的处于转色期、商品期和麻点期的香蕉果实可溶性固形物含量差异显著。 |
| 英文摘要: |
| Refractometer was used to measure the banana total soluble solids at veraison stage, commodity stage and pitting stage. Three of bananas juicing methods (constant temperature water bath, medium-speed centrifugation and filter paper filtration) were compared in the experiment. The results showed that using medium-speed centrifugation and filtered through filter paper method for the determination were more accurate in terms of accuracy. And using medium-speed centrifugation for the determination was more stable. Considering the comprehensive factors, medium-speed centrifugation is the most simple and fast way,and the measurement results of the method is good repeatability and stability.The total soluble solids content existed significantly difference among veraison stage, commodity stage and pitting stage based on this method. |
