Abstract

The latex of milkweed plant (Calotropis gigantea) is known to have proteolytic activities. The research was conducted to evaluate the use of ammonium sulphate for partial purification of such enzymes. The phosphate buffer extract of the latex was first centrifuged to precipitate gum and non-proteinous matter. The supernatant was then treated with ammonium sulphate to achieve the respective degree of saturation, namely 35, 50, 65 and 80%. It showed that the use of ammonium sulphate at 65% degree of saturation was the optimum condition, and produced a partially purified enzyme with proteolytic activity which was not significantly different from that obtained from the use of the same salt at 80% degree of saturation. Nonetheless, the supernatant still showed a substantial degree of proteolytic activity, indicating that the latex contained a various types of proteases. Key Word: Milkweed plant (Calotropis gigantea), protease, partial purification

Abstract

Red fruit can commercially be obtained in extract (oil) form and capsulated oil (softcapsule). Within oil form, this product has lower tenacity and stability against light, heat, oxygen, and extreme environmental condition due to its content of easily degradable antioxidant group active compound. Red Fruit based essence product have been ever fortified into other food product, but only fortified into fried oil to improve carotene rate. One alternative to deal this problem refers to microencapsulation. Microencapsulation means the process of wrapping one certain central particle with other material to reach expected physical and chemical characteristic. Microencapsulation method used in this research has been spray drying. Research was arranged by using Completely Randomized Design that organized in factorial pattern involving two factors. First factor includes coating materials (soybean protein isolate and Na-caseinate), while second factor entails red fruit oil proportion (20 %, 30%, and 40%). The analysis covers moisture content, β-carotene, microstructure, microencapsulation efficiency, yield, antioxidant activity, and microcapsule stability against temperature. Results of analysis indicate that microcapsule with Na-caseinate had better quality compared to wrapping with soybean protein isolate. The best treatment comes from treatment combination with Na-caseinate wrapping in proportion of 20% red fruit oil. Microcapsule with the best treatment has moisture content of 1.34 %, β-carotene of 580.42 μg/g, microcapsule size of 36,98 μm, microencapsulation efficiency of 95,59%, and yield of 93,37%. The process of red fruit oil microencapsulation with Na-caseinate in proportion of 20 % can be used as an alternative to facilitate distribution process, to increase product storability, and product fortification process into other food product.Keywords: microencapsulation, red fruit, oil proportion, antioxidant stability, protein based coating

Abstract

Common konjac flour (CKF) from Indonesia has dark brown in color and itching property that considered unsuitable for human consumption due to the high presence of calcium oxalate. Therefore it needs purification.  The objective of this research is to reduce the amount of calcium oxalate as well as to increase its glucomannan content, viscosity, beside to produce white CKF. CKF was extracted by maceration method for 4 hours with 40% ethanol solution containing hydrogen peroxide. This extraction process was repeated at 60% ethanol solution, as well as at 80% ethanol solution. Hydrogen peroxide concentrations used in this experiment were 0.5, 1, 1.5, 2, 2.5, and 3%.  “Bath type” ultrasonic was used to purify CKF for 15 minutes. The extraction process was similar to the above maceration method. The results showed that both maceration and ultrasonic extraction methods increased the degree of whiteness, glucomannan, and viscosity, in fact reduced the amount of calcium oxalate content. Conclusion of this experiment was that both extraction methods (maceration and ultrasonic) were achieved, when  CKF was washed in three levels of  ethanol solution, which  were at 40 %, followed by 60% and  80% ethanol  solutions  containing  0.5% hydrogen peroxide, in each stage of purification process.  The least hydrogen peroxide residue in CKF was shown by treating CKF in three levels of ethanol solution containing 0.5%  H2 O 2  which was 123.24 ppm.
