| Basil leaves (Ocimum Americanum Linn) are commonly known to contain phenol and flavonoid compounds which can act as antimicrobial and antioxidants. In general, the bioactive compound can be obtained by conventional extraction method, maceration. To increase the amount of bioactive compounds which can be extracted, it is necessary to conduct pre-treatment using Pulsed Electric Field (PEF). PEF has an advantage in increasing the compound transfer contained in cells to be extracted from the plant tissues via electroporation mechanisms, without causing significant temperature changes. This study aims to determine the effect of electric field strength variations (2, 3, and 4 kV/cm) and duration of pre-treatment (1, 2, and 3 minutes) to total phenol and... |

| The purpose of this study was to determine the effects of feed rate and inlet air velocity on the physicochemical properties of porang flour by using Central Composite Design Method of Response Surface Methodology (CCD –RSM), in order to ascertain whether the CCD-RSM as a predictive approach is accurate in optimizing porang flour production. Advanced instruments, including FTIR (Fourier-transform Infrared Spectroscopy), SEM (Scanning Electron Microscopy), DSC (Differential Scanning Calorimetry) XRD (X-Ray Diffraction), and PSA (Particle Size Analyzer) were used to characterize an optimum micro-mill milled porang flour (OMMPF). The predicted optimum conditions for producing porang flour were feed rate of 48.86 kg/h, and an inlet air velocity of 9.00 m/s,... |
