Foam Properties, Detergent Abilities and Long-term Preservative Efficacy of the Saponins from Sapindus mukorossi
JOURNAL OF FOOD AND DRUG ANALYSIS(2020)
Abstract
Pericarp of Sapindus mukorossi Gaertn has been used as a natural detergent and its extract is commercially utilized as a foam-stabilizing and emulsifying agent The goal of this study is to investigate the foam properties, detergent ability and long-term preservative efficacy of the saponin from the pericarp of S mukorossi Gaertn The crude saponin content in the pericarp of S mukorossi Gaertn was 14 2% and the total saponins content in the crude saponins extract was 85% (w/w) The foaming power of the 0 5% crude saponins extract solution from S mukorossi Gaertn is 65% of 0.5% SLS solution and similar to that of 0 5% Tween 80 solution The R5 value of 91 7% represented good foam stability of the crude saponins extracted from the pericarp of the plant With the reduction of water surface tension from 72 mN/m to 51 7 mN/m, the 0 5% crude saponins extract solution has wetting ability The sebum-removed experiment Indicated that the crude saponins extract has moderate detergency The results of the long-term preservative efficacy test revealed that the 0 5% crude saponins extract from the pericarp of S mukorossi Gaertn is an effective preservative against Staphylococcus aureus ATCC 6538, but inefficacious against Escherichia cob ATCC 8739 and Aspergillus niger ATCC 16404
