Abstract

A new method of ultrasound-assisted enzymatic extraction (UAEE) was applied to mulberry must treatment with processing variables of sonication frequency (FS), enzyme concentration (CE) and maceration time (TM) at constant temperature 20°C and pulse durations of 10s on and 5s off. A Box–Behnken Design (BBD) was used to investigate the main effect of the various variables on total phenolics (TPC), total flavonoids (TFC), total anthocyanins (TAC), lightest (L*) and Browning index (BI). The predicted model was found to be significant (p<0.05) with low standard error and high coefficients of determination (R2). The model was highly correlated to experimental results and this helped in the identification of the optimum operating conditions: FS=33.82kHz, CE=0.010% (v/w) and TM=11.58min, under which it predicted TPC=298.06mg/100ml; TFC=379.24mg/100ml; TAC=55.14mg/100ml; L*=3.51 and BI=1.19. The study shows that the UAEE could be employed to enhance the quality of must, reduce the time during the maceration process of juice or wine.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
