| Abstract: | In single factor tests, the inhibitory effects of vitamin C (VC), DL- malic acid and L-cysteine (L-Cys) amounts andtemperature on yacon juice browning were investigated. Based on the results of single factor tests, the optimization tests of the four factors were designed according to Box-Behnken central combination design principle, and the test results were analyzed by response surface regression. The results showed that optimal inhibitory conditions against yacon juice browning are as follows: VC amount 0.31%, DL- malic acid amount 0.30%, L-Cys amount 0.30% and temperature 89 ℃, and under these conditions the change rate of browning is 20.88%. |
