Abstract

The establishment of subcritical fluid application for zingiberene extraction was studied by employing water as a green solvent. The zingiberene content was observed by using Liquid Chromatography-Mass Spectrofotometry and regarding to the independent variable of temperature, extraction time, ginger-solvent ratio and aging time. By applying subcritical water, the critical value of zingiberene content obtained was 0.036%.  This value was approached by the surface modeling of alpha for rotatability design which performed at 125  C, 20 min of extraction time, 0.08 of ginger to solvent ratio and 9 min of aging time of extraction parameters. The surface modeling was validated by plotting the observed and predicted value of zingiberene content and evidenced by the value of R-square at 0.76.

Abstract

This work proposed a study of a direct enzymatic of vanillin formation by using rumen liquid which has enzymatic capability for tissue disruption of vanilla green pods to avoid the curing process. Application of enzymes during the formation of vanilla aromas and its extraction present nice opportunity to improve productivity, as the enzymatic reaction possibly substitute the microbial process in the traditional fermentation. Green vanilla pods were applied for the direct enzymatic extraction of vanillin, while liquid rument provide cell wall degrading enzyme in order to support the hydrolysis process (destruction) of cell wall. Glucovanillin were contacted with the β-glucosidase in the green pods due to the desruction of the cell wall, followed by the formation of glucovanillin into vanillin. Vanillin content of vanilla green pods was found higher in which by treating the vanilla green pods at 30 °C.
