Piper betle L. more commonly known as betel or local name of Sirih belongs to the family Piperaceae. Previous research shows that the leaves of P. betle possess tremendous beneficial effects including antimicrobial antioxidant anti-diabetic wound healing and gastro-protective properties. The presence of these beneficial properties indicates that leaf extract of betel has great potential for development into a wide range of health food supplements. In this study betel leaf extract was dried by spray-drying. The main purpose was for easy handling and the preservation of bioactive compounds. The process parameters of spray drying were inlet hot air temperature feed flow rate or pump flow rate and aspirator rate. Maltodextrin was utilized as the coating agent in the study. The properties of dried powder were investigated in terms of particle size distribution moisture content and degree of degradation of the active compound hydroxychavicol He. The experimental run and optimization work were designed using Box-Behnken method of Response Surface Methodology RSM. The optimum operation conditions for the lowest hydroxychavicol degradation with the lowest moisture content and the smallest particle size were obtained at inlet drying temperature of 140C; feed flow rate of 7.3ml/min and aspirator rate of 67.52. The optimal properties of spraydried powder obtained from this study were 28.61 of hydroxychavicol loss 6.96 um in size and 8.10 in moisture content.

Abstract

Piper betle L. more commonly known as betel or local name of Sirih belongs to the family Piperaceae. Previous research shows that the leaves of P. betle possess tremendous beneficial effects including antimicrobial antioxidant anti-diabetic wound healing and gastro-protective properties. The presence of these beneficial properties indicates that leaf extract of betel has great potential for development into a wide range of health food supplements. In this study betel leaf extract was dried by spray-drying. The main purpose was for easy handling and the preservation of bioactive compounds. The process parameters of spray drying were inlet hot air temperature feed flow rate or pump flow rate and aspirator rate. Maltodextrin was utilized as the coating agent in the study. The properties of dried powder were investigated in terms of particle size distribution moisture content and degree of degradation of the active compound hydroxychavicol He. The experimental run and optimization work were designed using Box-Behnken method of Response Surface Methodology RSM. The optimum operation conditions for the lowest hydroxychavicol degradation with the lowest moisture content and the smallest particle size were obtained at inlet drying temperature of 140C; feed flow rate of 7.3ml/min and aspirator rate of 67.52. The optimal properties of spraydried powder obtained from this study were 28.61 of hydroxychavicol loss 6.96 um in size and 8.10 in moisture content.
