Mature degree of banana for processing clear juice was determined. There were about 1% starch and 20oBrix of soluble solid content in entirely yellow banana. The largest press supported by entirely yellow bananas was lower than 600g.

• 经成分分析与质构测定,发现完全黄熟的香蕉硬度在600g(最大受力)以下,淀粉含量仅1%25左右,而可溶性固形物含量高达20oBrix,适合用于果汁加工,因此,选用硬度在600g以下完全黄熟的香蕉为原料进行澄清型果汁加工与研究。
