Abstract

The development of process engineering and the finding of plant-based new medicines are growing very fast. Pandanus conoideus Lam, an indigenous fruit plant in Irian Jaya, the eastern province of Indonesia is one of the well-known herbal plants. "Buah Merah" (Indonesian), meaning red fruit due to the bright red color of the main variety, is well known as a medicinal plant traditionally used as anti-cancer, anti diabetic, anti dislipidemia, anti-oxidant agent, etc., whose effects greatly depend on its total phenol, flavonoids, tocopherols, carotenoids, vitamins content, etc. Good-quality herbal medicine should be a phyto-pharmaceutical product, which requires certain prerequisites to obtain standardized extract or powder form. Good extract quality normally involves a well dried raw material in order to minimize the enzymatic and hydrolytic reactions. In this study, the effect of pre drying by Detente Instantanee Controlee(DIC) method is studied, as it opens up the plant cells' pores, so that the vaporization will be accelerated; and the thermal degradation is reduced. Thirteen operating parameters of DIC have been studied. The results showed that maximum moisture content reduction for a drying time of 180 minutes, of DIC-15 (0.2 MPa steam pressure, 3 cycles of 20 seconds each) was of 94.58%, and of DIC-16 (0.25 MPa, 4 cycles of 15 seconds, each) was 91.24%, which a/so produced 3.21% Catechin Equivalent (CE) and 6.44% Gallic Acid Equivalent (GAE), respectively. They were higher than those obtained from the conventionally-dried (CD) fruits without and after juice extraction which produced 2.61% and 1.13% CE, and 4.58% and 2.57% GAE, respectively. DIC pretreatment was also able to enhance cttocopherol extraction compared to those of CD red fruits (after juice extraction); and the DIC-19 (0.15 MPa, 2 cycles of 15 seconds, each) extract produced 3,2750.5 mg ct-tocopherol /kg extract, although the yield of the CD fruit extract without juice extraction was 6,631.95 mg/kg extract. This research is a collaboration between the fields of Engineering and Pharmacy.
