The seed of Parinarium glaberrimum Hassk was extracted with non polar solvent (hexane) and or polar solvent (ethanol). Antioxidative activity of extracts was measured by rates of carotene bleaching in the coupled oxidation of linoleic acid and b-carotene. Ethanolic-Hexanoic Extract (EHE) of the seed was found to possess the highest antioxidative activity. Furthermore, EHE was fractionated by silica column chromatography and eight major fractions were isolated according to UV absorption. Antioxidative activity of these fractions was evaluated in a b-carotene-linoleate system. Fractions III , I , and II showed the major activity, but fractions I and II have the best value of relative capacity, so they were chosen for further identification.

Peptone can be produced from soybean press cake and yeast by enzymatic hydrolysis with papain. The activity of papain used in this experiment against casein is indicated by Vm (2000 unit) and Km (0.8%). The process condition for soybean press cake was : [S] = 3.72%, [E] = 0.4%, 60 0C, pH 6.2-6.3, 5 hours, while for yeast was [S] = 4.76%, [E] = 0.2%, 60 0C, pH 5.8-5.9, 5 hours. The yield of the hydrolysis process of soybean press cake peptone was 12.1%, while that of yeast was 18.9%. The peptone obtained was brownish yellow in color with moisture content of 3 and 5%, ash content 6 and 7 %, total protein 9 and 11%, solubility 98%, amino nitrogen 1.9 and 2.82, and AN/TN ratio = 26.47 and 27.62%, respectively. The chromatographic pattern of the peptone using gel filtration column of Superdex-75 appeared to be the same as that of the commercial soy pepton. Growth test with E. coli, S. aureus, and B. subtilis showed that soybean press cake and yeast peptone could be used as component in media for microbial growth.

Dual-modified arrowroot starch using hydroxypropylation and cross-linking methods was carried out to overcome the deficiency in of native arrowroot starches for food processing application. The modification applied the combination concentration of propylene oxide (8, 10, and 12%) and ratio of sodium trimetaphosphate (STMP):sodium tripolyphosphate (STPP) (1%:4%, 2%:5%, and 3%:6%). The resulting dual-modified arrowroot starches had lower gelatinization temperature (68.45–70.00ºC) than that of native arrowroot starch (72.85ºC). The modified arrowroot starches also had a higher peak viscosity (>5500 cp) than that of native arrowroot starch (4209 cP). Breakdown and setback viscosity of modified arrowroot starch was higher values than the native. At acidic pH, the viscosity decreased at different levels of temperature changes as compared to that of normal pH. Modified starch made with 8% propylene oxide and ratio of STMP: STPP 2%:5% and 3%:6%; as well as that made with 10% propylene oxide and 1% STMP:4% STPP had the lowest syneresis tendency. Decrease in the paste clarity occured with increasing concentration of STMP:STPP. The sedimentation volume of the modified starch was higher (29.17-35.83%) than that of native starch (28.08%), except for those made with 1% STMP: 4% STPP at concentration of propylene oxide 8% and 12%. The gel strength increased (61.77-78.97 gf) at 8% propylene oxide, but decreased (66.50-47.77 gf) at higher concentrations.

Anthocyanin is a natural pigment with color varying from red, purple, blue to yellow. The stability of its anthocyanin color is affected by pH, temperature and light. Purple sweet potato is rich in anthocyanin, particularly a stable acylated anthocyanin. This research was conducted to study the effect of pH on color and antioxidative activity of anthocyanin extracted from purple sweet potatoes harvested from Cilembu-Sumedang, Banjaran-Bandung, and Pakembangan-Kuningan. The experiments applied a completely randomized design with two replicates analyzed triplo.The results showed that the total number of monomeric anthocyanin in purple sweet potato harvested from Cilembu (3.78±0.08 mg cyanidin-3-glucoside/g dry weight, dw) was higher than that of Banjaran (3.18±0.01 mg/g) and Pakembangan (2.25±0.01 mg/g). The color of purple sweet potato anthocyanin extract was pH dependent. The color changed from red, faded red, purple, blue, green and yellow along with the increase of pH from 1 to 14. The content of anthocyanins from three locations of purple sweet potatoes differed from each other (p<0.05). Radical scavenging activity and reducing power of purple sweet potato anthocyanins extract at pH 1 was higher than that at pH 4.5 and pH 7.

Each kind of oil has different characteristics and physico-chemical properties. Therefore, cooling method applied during dry fractionation of oil must be specifically designed. Fractionation condition of coconut oil commonly uses the fractionation data of palm oil, soybean oil, butter milk, and other commercial oil. Therefore, a more suitable cooling method for coconut oil needs to be investigated. The study showed that there were three distinct cooling phases critical to crystallization process, i.e. initial cooling, critical cooling and crystallization phase. The initial cooling phase is a process of lowering the rejuvenated oil temperature to the temperature for the onset of oil crystallization. For coconut oil, the onset of crystallization temperature was found at 29°C. The critical cooling phase is cooling from 29°C to the crystallization temperature. Crystallization phase is a phase to maintain the oil temperature constant at a predetermined crystallization temperature. In the initial cooling phase, melted coconut oil might be cooled quickly to save time but in the critical cooling phase, it should be done with a cooling rate of less than 0.176°C/min to produce a physically stable crystal. This study has successfully formulated a typical dry fractionation for coconut oil at pilot plant scale (120 kg) and resulted in an effective cooling procedure to produce oil fractions with physico-chemical properties as expected. The conditions and essential requirements that must be managed and maintained in a dry fractionation stage of coconut oil had been identified and were known. Hence, the fractionation process for specific purposes can be designed in a more practical way.

Taro is one of non-rice carbohydrate sources which is rich in dietary fiber and minerals, mainly potassium, magnesium, calcium, dan phosphorus. The objectives of this research were to obtain taro flour with high amylose content and various pasting properties for different food ingredients through controlled fermentation technology using commercial inoculums. There are two taro varieties studied, namely Bentul and Satoimo. The fermentation time conducted were 12, 24, 36, and 48 hours. The commercial inoculums added were NKL, Bimo CF, and Fermipan. The results showed that fermentation of taro with Bimo CF for 48 hours increase the amylose content (66.82% for Bentul variety and 61.08% for Satoimo). The growth of mold contributed to the increase in amylose content. Longer fermentation time increase the breakdown and final viscosity of Bentul taro flour, but decrease the same characteristics in Satoimo flour. Fermented bentul taro flour has amylograph pattern similar to type A, while Satoimo has type C. Fermentation using Bimo CF for 48 hours produced the highest final viscosity in Bentul taro flour (3405 cP) thus it is potential to be used as a filler in products processed at low temperature. Meanwhile Satoimo taro produced flour with lowest breakdown viscosity (0.75 cP), therefore it is potential to be used as a filler in products processed at high temperature.

Lysozyme is one of the proteins found in hen egg albumin. Besides known as antimicrobial agents, lysozyme hydrolysis products can also function as antioxidants and as angiotensin converting enzyme (ACE) inhibitors. The lysozyme is also known to have lysine and arginine that can give a sweet taste. The research aimed to isolate lysozyme from commercial laying hen eggs. The isolation and purification of the eggs lysozyme was done by preparative and analytical separation technique using cation exchange resins. The preparative separation was carried out by centrifugation of a large sample size of 205 g by centrifuga-tion, while the analytical separation only used only 3.16 g sample with a column measuring 13 cm in length and 3 cm in diameter. The number of samples isolated by preparative separation is greater than that with analytical method. The preparative separation was conducted in order to obtain the pure isolated lysozyme in higher quantity for further testing purposes. The purity of the isolated lysozyme from preparative separa-tion was 68.62% and the purity of isolated lysozyme from analytical separation was 63.03%.

Dried tekwan is a traditional restructured-fish product of South Sumatera processed by convectional drying. The study aimed to determine the effect of fish and tapioka ratio and tekwan’s length on the physical quality of the dried tekwan. The physical quality of dried tekwan made with different ratio of fish and tapioca ratio (1:1, 1.5:1 and 2:1 (w:w)) and length 1, 2, and 3 cm were investigated. The physical quality evaluated were the degree of whiteness, rehydration ratio, water holding capacity (WHC) and microstucture. The drying profile and proximate composition were also evaluated. There was no difference in the rate of drying of different fish:tapioca ratio as well a different tekwan length when free water evaporation was progressing. However, difference in drying rate was observed when the water content reached the equilibrium. Ratio 2:1 of fish and tapioca and 2 cm length of tekwan was found the to be best treatment and resulting in dried tekwan with moisture content 10.22%, ash 1.9%, protein 27.9%, fat 1.38%, carbohydrate 58.6%, whiteness 45.96% and expressible moisture content 2.06%. Microstructure of dried tekwan with 2:1 ratio showed more compact structure and slight damage than 1.5:1 ratio. However, dried tekwan with 2:1 ratio still had lower rehydration properties than other treatment.
