| 摘 要： | 以苹果、柑橘、猕猴桃、鲜食葡萄、甜瓜五种代表性水果为试材,对折射仪法测定水果可溶性固形物含量的四种取汁方法（脱脂棉过滤法、单层滤纸挤汁法、双层擦镜纸挤汁法和四层纱布挤汁法）进行了比较试验。结果表明，双层擦镜纸挤汁法和四层纱布挤汁法均为适宜取汁方法。其中以双层擦镜纸挤汁法更为简便，两种方法的测定结果在实验室间均具有良好的重复性和再现性。

| Abstract: | Apple, citrus, kiwifruit, table grape and melon were used as representative materials to compare the effects of four juicing methods for determination of total soluble solids(TSS) content in fruits by refractometer. Four juicing methods were respectively filtrated with degrease cotton, juicing with single filter paper, juicing with double lens cleaning paper and juicing with four layers of gauze. The results showed that, both juicing with double lens cleaning paper and juicing with four layers of gauze were suitable methods for determination of total soluble solids content in fruits by refractometer, and the method juicing with double lens cleaning paper was more convenient than the method juicing with four layers of gauze. According to verification tests in three laboratories, two juicing methods screened all showed repeatability and reproducibility. |
