The mangosteen fruit rind fraction positively contains flavonoids and polyphenols which can act as an antioxidant anti-inflammatory. The use of mangosteen rind fraction in topical preparations requires a good delivery system to support percutaneous penetration, one of which is nanoemulsion. The topical use of nanoemulsion has low viscosity and to increase the penetration of active compound, therefore it needs to be formulated into nanoemulgel preparations. In formulating nanoemulgel preparations, the optimum concentration of gelling agents is needed to obtain a nanoemulgel that meets the physical and chemical characteristics of the gel preparation. Therefore we need an optimization of glyceryl polyacrylate gelling agent in order to obtain a nanoemulgel with good characteristics. Nanoemulgel for mangosteen rind fraction was made in four formulas with gelling agent concentrations of glyceryl polyacrylate as much as 1% (F1), 2% (F2), 3% (F3), and 4% (F4). The nanoemulgel has been evaluated for its physical and chemical characteristics including organoleptic test, homogeneity, adhesion, viscosity, dispersibility, and pH. The active substance release test is carried out on a gel that meets the overall requirements for physical and chemical properties. The analysis showed that the F1 produced a nanoemulgel that met the physical and chemical characteristics of the semisolid preparations. Organoleptic of F1 isi semisolid form with yellow color and typically garcinia fruit rind fraction odor, homogen mixture, 1 ± 0.02s adhesion, 8340 ± 555 viscosity, 6.87 ± 0.39 cm2 spreadability, and 6.39 ± 0.01 pH. The results of the release of active substances showed that the F1 formula was able to release 49.9% of active substances in 10 minutes and within 480 minutes was able to release 96.54% of active substances with a total flux of 5.36 µg / cm2 minutes which fulfill the release requirement.Based on these results, it can be concluded that glyceryl polyacrylate with a concentration of 1% can produce good nanoemulgel.

Chikuwa is one of Japanese traditional fishery food product that commonly made from potato starch, fish surimi, and some spices. To enhance Chikuwa physical and chemical properties especially in texture attribute and protein content, Gelatin can be added. Gelatin is a partial hydrolysis protein that usually added in food making process to improve the gumminess quality and the protein content. Gelatin can be derived from bone collagen, skin and fish scale. The purpose of this study is to analyze the effect of gelatin from various skin fish to the physical and chemical characteristics of Chikuwa. The research method used is experimental laboratories using a completely randomized design (CRD) with 3 replications. The data analysed with ANOVA and continued with BNJ analysis if there is a significant difference between the treatments. This research has divided into two stages. The first step aim is to make the gelatin from the skin of seabass, payus fish and tilapia with 3% concentrations. The second step is Chikuwa making added with gelatin. The parameters that observed are water content, protein content, white degree, gel strength, sensory attributes, folding, bite. The results showed that Chikuwa with the addition of gelatin from seabass, payus and tilapia skin are significantly different (p <0.05) due to the physical and chemical characteristics of Chikuwa. The best Chikuwa quality is Chikuwa with the addition of seabass gelatin, where the gelatin yield is 18.03 ± 0.68; the gelatin gel strength is 251.11 ± 1.08 bloom; the viscosity is 5.80 ± 0.15 cP; the gel Chikuwa sample strength is 954.54 ± 0.56 gcm and protein content is 22.01 ± 0.98%

Traditional food is usually packed with natural packaging materials such as young coconut leaves (janur), but a little scientific information is available related to the packaging material. This study aimed to examine the physical and chemical characteristics of fresh and steamed janur (30 minutes steaming at 100 0 C). The physical and chemical properties of janur were expected to be the basis for the development of janur as an environmentally friendly packaging material. The results showed that fresh and steamed janur color was greenish-yellow and brownish-yellow. The fresh and steamed janur had a tensile strength 19.19 MPa and 30.62 MPa; water content 73.54% and 69.57%; and fat content 1.85% and 0.54%, respectively. After steaming, the microstructure of the cells became finer and irregular. The dominant fatty acid in fresh janur and steamed janur was palmitic acid (24.27%), and palmitoleic acid (38.56%), respectively. The treatment of steaming of janur influenced the physical and chemical characteristics of packaging materials.

The physical and chemical characteristics oven dried millet flour from dehulled millet soaked in different media was studied. Depigmented oven dried dehulled millet flour was produced by soaking dehulled millet in different solutions; water, 1% NaCl, 1% Na2CO3, and 1% citric acid. All samples were soaked in their respective solution for 12h, dried in the oven at 60oC for 6h then milled into flour and sieved through 710µm mesh size. The physical properties of oven dried dehulled millet; colour had L* (whiteness value), a* (redness values), and b* (yellowness values) that differed significantly ranging from 66.74 to 84.21, 0.85 to 1.43, and 6.89 to 12.69 respectively. The minimum, mean and maximum particle size distributions of samples ranged from 9.53 to 23.41µm, 29.09 to 50.15µm and 59.46 to 176.01 µm respectively. Starch granules in micrographs of oven dried depigmented millet flours were irregular, compact and polygonally shaped. Gelatinization properties of oven dried millet flour; the onset temperature (To), peak temperature (Tp), end set temperature (Te) and enthalpy varied significantly ranging from 70.15 to 97.65 o C, 79.48 to 102.31 o C, 83.30 to 104.96 o C, and 6.70 to 28.41 (J/g) respectively. Chemical properties comprising of moisture, fats, ash, protein, crude fiber, pH, total titratable acidity, pH of soak solution, phytates and tannins varied significantly ranging from 10.19 to 10.88%, 4.27 to 4.61%, 0.71 to 1.19%, 7.25 to 8.67%, 1.00 to 1.08%, 4.35 to 8.45, 0.001 to 0.084%, 3.32 to 9.93, 0.60 to 0.62, 1.84 to 6.45mg/g and 3.06 to 6.68 mg/g respectively. Depigmenting dehulled millet by soaking in 1% Na2CO3 impaired the colour of sample ODMF2 while depigmenting dehulled millet grains by soaking in 1% citric acid solution for 12 h improved colour of sample ODMF1.

The objective of this present study was to investigate the effect of feeding fermented mixture of papaya leaf and seed meal (FERM) on the physical and chemical characteristics of meats of the Indonesian indigenous crossbred chicken (IICC). The study was carried out with 300 day-old IICC. The chicks were randomly distributed to five treatment groups, i.e., CONT (control diet based on corn-soybean- diet), FERMA (diet containing 1% FERM), FERMB (2.5% FERM), FERMC (5% FERM) and FERMD (7.5% FERM). Each treatment group consisted of 6 replicates with 10 IICC in each. At week 8, one chick from each replicate was randomly taken and slaughtered. After being de-feathered and eviscerated, samples from breast and thigh meats were obtained. Results showed that the increased levels of FERM was followed by the increased (P<0.05) pH values, moisture and crude protein content of breast meats of the IICC. Dietary incorporation of FERM especially at the level of 2.5% increased (P<0.05) the content of fat in the breast meat of IICC, while further increased levels of FERM did not alter (P>0.05) the fat content of the IICC breast meat. Dietary treatment did not have any effect (P>0.05) on the lightness (L*) values of breast meat of the IICC. The redness (a*) values were higher (P<0.05) in FERMD breast meat than other. FERM diet resulted in lower (P<0.05) yellowness (b*) values in the IICC breast meat. The pH values and moisture content of thigh meat increased (P<0.05) with the increased level of FERM. The WHC decreased (P<0.05) with the elevated levels of FERM in the diets. There was an increase (P<0.05) in crude protein concentration in FERMA as compared to the other meats. Crude fat and ash concentrations in thigh meat were affected (P<0.05) by the treatments. Dietary treatments had no impact (P>0.05) on L* values of thigh meats. Feeding FERM at 7.5% from diets increased (P<0.05) and decreased (P<0.05) the redness and yellowness of meats. In conclusion, dietary inclusion of FERM especially at the level of 7.5% from diets improved the physical and chemical characteristics of the IICC meats.
