Abstract

Areca nut (Areca catechu L) is a rich polyphenol source which is potential health-benefit. Polyphenol could extract from the sources and then converted to solid powder by spray drying. Polyphenol powder is easy to use and to introduce it into food (materials). The objective of this study was to determine the effect of maturation degree of areca nut (unripe, ripe) and binder treatment (without a binder, arabic gum 2% w/v) on the  physicochemical properties and citotoxicity of spray-dried areca nut extracted powder. This study used a completely randomized design (CRD). Data were analysed statistically used an analysis of variance. Analysis of the results exhibited unripe areca nut produced powder  with higher in yield, moisture content and total phenolic content but had no significant effect on pH and lower in bulk density and solubility than ripe areca nut. Arabic gum treatment produced powders with higher in yield, and solubility, but had no significant effect on moisture content and lower in bulk density, pH and total phenolic content than the treatment without binder. The areca nut extracted powders from all combination of treatments exhibited high cytotoxic activity against brine shrimp larvae with LC50 less than 1000 ppm, excepted the powders from ripe areca nut with arabic gum.

Abstract

This study highlighted the effect of microwave pretreatment on betung bamboo on the chemical structural and morphological changes. The hydrothermal condition was performed in varying power loading (330, 550, and 770 W) and microwave irradition time (5-12.5 min). FTIR spectroscopy, X-Ray diffraction and SEM-EDS analysis were utilized to confirm the characteristic changes after pretreatment. The results showed that the severe pretreatment condition tended to increase the carbohydrate losses. From FTIR spectra, microwave pretreatment tended to decrease absorbancy of functional group bands. After microwave pretreatment for 12.5 min (770 W), the band around 1736 cm-1 (C=O in xylan) disappeared in the samples. The syringil propane unit was lower than that of guaiacyl lignin under microwave pretreatment. The disruption of the structure of the cell wall increased the accessibility of cellulase to lignocellulose. Except microwaving for 5 min (330 W), the microwave heating caused carbon and oxygen increasing compared to untreated samples. The increase in crystallinity index of pretreated bamboo suggested the selective degradation of amorphous components.
