Grain drying with bed dryer is generally effective with high temperatures, but this can increase fissured rice percentage. This can be overcome by combining drying method with tempering. These study were aim to examine drying temperature and duration on bed dryer using intermittent high temperature dryer, and its effect on quality variety of Ciherang with 20-22% moisture content. These research method consists of drying treatment without tempering using 35°C, 60°C and 80°C temperatures to 14% moisture content. Drying treatment with tempering consists of initial drying process-initial tempering-second drying- second tempering or without tempering, where the first drying temperature were 80°C for 20 minutes, 60°C for 30 minutes and second drying temperature were 60 °C and 35°C to 14% moisture content. The tempering duration used was 90 minutes. Results showed the grain drying method without tempering 35°C gave the highest percentage of head rice. However, the use of tempering had significantly reduced cracking and increased head rice percentage compared without tempering at the same temperature. Initial drying of 60°C for 30 minutes-tempering for 90 minutes-drying both temperatures of 35°C to 14% moisture content had been able to produce high head rice and low fissured rice percentage respectively 81.41% and 10%.

Abstract In the processing, the red ginger powder was dried at 50°C. Red ginger powder is hygroscopic, so it is easy to absorb moisture. This research aims to determine (i) the isothermic absorption curve model in red ginger powder with different fineness modulus and (ii) the expiration date using the critical moisture content method in various types of packaging materials. Moisture sorption isotherm of red ginger powder was determined by the static gravimetric method at 300C. The relationship equilibrium moisture content between relative humidity (RH) is described by the Hasley, Chen-Clayton, Henderson, Caurie, and Oswin Models. The Estimated shelf life is determined using the ASLT (accelerated shelf-life testing) method and calculated using the Labuza model with a critical water content approach. The results obtained that moisture sorption isotherm red ginger powder has sigmoid shape a type II. Henderson is the model that illustrates the accuracy of the ISA curve of red ginger powder of 60 mesh particle size while the Chen-Clayton Model illustrates the accuracy of the ISA curve of red ginger powder of particle size of 80 mesh. The shelf life of red ginger powder is 60 mesh particle size and using HDPE, PP, and aluminum foil packaging which is stored at 75% RH and 300C temperature is 118.85 days, 467.63, and 609.26 days, respectively. The shelf life of red ginger powder 80 particle size is 148.17 days, 582.98 days and 759.54 days.

Oleoresin extraction is generally carried out by conventional maceration method, which takes up to 7 hours. Microwave-assisted maceration extraction method has the potential to reduce extraction time and solvent consumption. This study aims to examine the effect of applying the microwave-assisted extraction method on the yield and quality of oleoresin. The material used in this study was white pepper. Microwave maceration extraction as the main treatment was carried out by dissolving 200 grams of white pepper powder (60 mesh) with 800 mL ethanol (1:4), at a power of 100 watts, a maximum temperature of 50 oC, with 4 extraction times (30 minutes, 60 minutes, 90 minutes, and 120 minutes). Extraction by conventional maceration (7 hours) was performed as a comparison. The results of this study indicate that the microwave maceration extraction method produces a higher yield than the conventional maceration method. The average yield of microwave maceration extraction for 30, 60, 90, and 120 minutes were 8.76 %, 8.32 %, 9.46 %, and 10.37 %, respectively, higher than conventional maceration (8.61 %). The quality of white pepper oleoresin extracted by microwave maceration is different from conventional maceration in terms of the type and amount of oleoresin components. It can be concluded that the microwave maceration extraction method is effective in increasing the yield and quality of white pepper oleoresin compared to conventional maceration.
