3.4. Optimization of UAHE parameters and validation of the model
As shown in Supplementary Table S1, the optimal extraction
conditions for achieving the maximal yield of pectin obtained by
differentiation of the quadratic polynomial model were as follows:
power intensity of 12.56 W/cm2, extraction temperature of
66.71 C and sonication time of 27.95 min; the predicted maximal
yield corresponding to these conditions was 27.46%. However, considering
the feasibility in experiment, the optimal extraction conditions
were slightly modified as follows: power intensity of 12.56 W/cm2 (amplitude of 58%), extraction temperature of
67.7 C, and sonication time of 28 min. The experimental yield of
pectin was about 27.34 ± 0.25% (n = 3), which was close to the predicted
value. This result further confirmed that the model was adequate
for predicting the yield of pectin using UAHE.
