Giovani Anggista , Ilyas Teguh Pangestu, Dwi Handayani, M. Endy Yulianto, Septi Kusuma, in this paper explain that the main part of ginger used is rhizome. Processed ginger products that can be developed are ginger oleoresin which contains components of gingerol, shogaol, zingerone, resin and essential oils. Ginger oleoresin content ranges from 3.2 - 9.5%, while the content of gingerol in oleoresin is between 14-25% and shogaol between oleoresin. 2.8-7.0%. Considering the benefits of high-antioxidant ginger which functions as an anti-inflammatory and prevents tumor growth, it is necessary to extract the ginger rhizome. The purpose of this study was to determine the factors that most influence the extraction of gingerol from the ginger rhizome using a stirred extractor and relatively good conditions. Experiments were carried out with various solvents, pH and temperature. Solvents 4 liters and 8 liters, pH 4 and 6 and temperatures 60oC and 100oC. The Gingerol content is measured by a VIS spectrophotometer. The most influential factor in extraction of ginger was determined by experimental design 23. The analysis of the results showed that for extracting 500 grams of powdered ginger using water as a solvent, the most influential factor was pH, in this case, at pH 6 containing 4% ginger.

Abstract Vegetable oil is one of plantation commodity and used as food source and oleochemical. One of the connection between vegetable industry and oleochemical industry is the conversion of vegetable oil into fatty acid. Indonesia is one of major producer of Crude Palm Oil (CPO), Palm Kernel Oil (PKO) and Cocos Nucifera Oil (CNO), but Indonesia is also import fatty acid in the application of paint, plastics, cosmetics, detergent and soap industry. These facts show a pityfull condition of vegetable oil industry. Therefore, it is neccesary to take an effort in order to fulfill our domestic demand of fatty acid. Up to now, the fatty acid is produce by converting CPO into fatty acid, which provide high cost production due to the expensive process of CPO production. An alternative process was proposed by cutting the two stages of fatty acid production into one stage. This stage covered the direct enzymatics production of fatty acid from fresh fruit of palm oil. The lipase of palm oil is inactivated in a microwave based-enzymatics hydrolysis bioeractor. The research objectives was developing the fatty acid production through microwave biochemical process by activate the lipase enzyme of the fresh fruit of palm oil. The parameters examined were including pH, ratio of water-fruit, and the milling of the palm oil as time function. The lipase activity as a result of microwave tunning up process was increasing along with the increasing of the reaction temperature. Without the addition of buffer, the acidity of the system decreased along with the production of fatty acid. Along with the increasing of the water concentration, the fatty acid produced was also increased. Â Key Words: fatty acid, lipase, microwave

Abstract Wintergreen (Gaultheria fragantissima) is the source of the essential oil of wintergreen which is comprised predominantly of methyl salicylic. During this time wintergreen is not yet economically developed because of the lack of the cultivation technology. One of effort that is needed to be studied beside the cultivation tecnology andÂ the wintergren oil quality development is the product diversification. wintergreen comprised by far the highest concentration of both free salicylic and total salicylic acid which is expected of a plant known for the formation of the wintergreen oil, an essential oil consisting primarily of methyl salicylic. The concentration of total salicylate found in wintergreen is over 20 fold greater than the total salicylic concentration (salicylic and any derivates combined) found in Filipendula, and 100 fold greater than that found in Lemon Thyme. The active form of salicylic acid in wintergreen is Gaultherin. Gaultherin has many properties related to human health. Gaultherin consists of methyl salicylic conjugated to the disaccharide, primeverose. When plant tissues are disrupted the endogenous gaultherin is rapidly lost, presumably by enzymatic hydrolysis with the release of methyl salicylic. The problem is until this time there is not yet available an effective method for the gaultherin extraction. The difficulties faced on the gaultherin production are the fact that along the gaultherin extraction. and along with the disruption of the wintergreen tissue, the gaultherin is hydrolyzed into its individual components which are methyl salicylic and disaccharide. The alternative process for the gaultherin production from wintergreen is the gaultherin production process by enzyme inactivation andÂ extraction process in an inactivation extractor using a n organic solvent (alcoholic solvent extraction). This paper is intended to study the enzyme inactivation rate which is play an important role in the dimension determination of the process equipments. Enzyme inactivation can be describes as first orde reaction. The enzyme inactivation constant Â kp is the temperature, pressure, and water concentration function. The dependency, model of Â the temperature based on Arhenius type while the pressure dependencyÂ is based on Eyring equation. Â Keywords : gaultherin, inactivation. kinetics

This study was to propose the use of a simple heat and mass transfer based model to predict the evolutions of the moisture content and temperature of cassava chip undergoing superheated steam drying (SSD). Cassava chip has been chosen as the product to be simulated because of its various uses in the food especially as modified cassava flour (mocaf). Recently, superheated steam drying (SSD) has received much attention as an alternative drying technique for heat-sensitive biomaterials. There are a very limited number of works that report attempts to model this drying process, although there are a number of works that report studies of this drying technique experimentally. The results showed that the drying of the product is affected by the drying steam temperature and the product characteristics. The model was found to be able to predict the heat and mass transfer behavior. Keywords: Cassava chip, mocaf, superheated steam drying
