also shows the astringency of the CNF30, CNF45, and CNF60 solutions. Compared with the CNF solutions with no added NaCl, the 0.15 and 0.30 g/L solutions were more astringent than 0.075 g/L solution in taste, thus revealing the effect of CNF concentration on astringency. The astringency of the 0.075 g/L CNF solution without and with 3.0 g/L NaCl group was difference insignificantly. However, for the 0.15 and 0.30 g/L CNF solutions, the experimental group (i.e., with 3.0 g/L NaCl) was significantly less astringent compared with the control group (i.e., without NaCl).
