• W97528900 abstract "Betel (Piper betle L.) is one of the invaluable medicinal plants originated fromMalaysia. Its leaves have been used traditionally for various medication purposes.Scientific research on the leaf of this plant reveals that it possesses many beneficialbioactivities and its extract from betel leaves has a great potential to be used indeveloping commercial products. However, there is a lack of research on theprocessing aspects to produce its bioactive extract.This research studied three key processes including drying, solid-liquid extraction,and freeze drying which are involved in processing of bioactive extract from betelleaves. Different experiments were designed and carried out to look into the effectsof various operating parameters on the qualitative and quantitative aspects of betelleaves extract. Hydroxychavicol (HC) and eugenol (EU) were selected as the qualityindicators of the product because these two compounds were reported to play animportant role in the bioactivities of betel leaves including antioxidant, antiinflammatory,and anticarcinogenic and antibacterial. The effect of drying temperature on the quality of betel leaves and drying kineticswere studied in order to determine the optimum drying temperature. Changes in theconcentration of HC and EU reveal that the optimum temperature for drying of betelleaves was 70oC because degradation of HC and EU was observed above thistemperature. Logarithmic model was found to be the most suitable model among theselected thin layer models in predicting the process.Water was the most suitable solvent for extracting betel leaves compared to ethanol,ethyl acetate, and hexane. This was because it gave highest yield and the extract fromwater indicated high antioxidant and anti-inflammatory activities in which theactivities were related to HC and EU. The optimum extraction temperature wasdetermined as 60oC to avoid degradation of EU. The ratio of water to solid of 30:1(ml:g) was found to be optimum based on analysis of Response SurfaceMethodology (RSM). Extraction kinetics of betel leaves reveals that the optimumextraction time is one hour. A new model named equilibrium driven solid-liquidextraction (EDSLE) model was developed and successfully applied in describing theprocess.The study of freeze drying process of betel leaves extract was conducted in twosections namely freezing and drying. The freezing kinetics data shows that thefreezing point of betel leaves extract with 20%SC was about -4oC. Prediction offreezing kinetics and freezing time was carried out successfully with numericalmodel. The results of drying kinetics of betel leaves extract show that the increase ofdrying temperature increased the drying rate. Midilli et la. model was found to be themost effective one among the selected models for modeling of the process." @default.
