Abstract

Durian seeds (Durio zibethinus Murr.) are one part of the durian fruit which has a high carbohydrate content so that it is a potential source of maltodextrin. The production of maltodextrin from durian seed starch has been carried out using the α-amylase enzyme. This study aims to determine the mass of durian seed starch substrate required to produce maltodextrin with the best yield and value of Dextrose Equivalent (DE). Starch with masses of 5, 10, 15, 20, and 25 grams suspended in CaCl2 was hydrolyzed with α-amylase for 90 minutes. The results showed that the best mass of durian starch was 15 grams with a maltodextrin yield of 25.842% and a DE value of 11.493. Maltodextrin from durian seed starch has the potential to be developed because it has met the requirements of DE <20.

Abstract

Ketoprofen coated tripolyphosphate modified chitosan nanoparticle was resulted from ionic gelation process by ultrasonication, centrifugation, and spray dry methods. Particle was analyzed by particle Size Analyzer. Dissolution and stability of them have conducted by Row Hansen methods at 37±0.5 °C and 150 rpm and using climatic chamber at 40±2 °C and relative humidity 75±5% for 3 months, respectively. Anti-inflammatory activities have conducted by Plate Reader methods. The result showed that B formulae have particles diameter of 563.1±157.5 nm and entrapment efficiency of 89.663%, respectively. Dissolution behavior showed that ketoprofen restrained released within acid medium and maximum released within base medium of 11.35-15.87% and 45.73-99.25%, respectively. Kinetically, dissolution of ketoprofen within intestinal and gastric pH condition was Korsmeyers-Peppas kinetic models. While, stability behavior showed that B formula has ketoprofen percentage left in nanocapsule after 3 months greater than 90% with water content and shelf life of 19.68%, and 14.19 week, respectively, and degradation kinetic model followed Avrami-Eroveef equation. Anti-inflammation test showed that B formula had the COX-2 inhibitory activity of 90.86% is higher than free ketoprofen.

Abstract

Rejected Dragon fruit (Hylocereus polyrhizus) is rich in anthocyanin compounds that can be used as additional ingredients in liquid soap formulas, thereby increasing the quality of soap as an antioxidant that protects the skin from the effects of sunlight and pollution. The purpose of this research was to determine the mass of rejected dragon fruit extract which produced liquid soap with the highest pH and foam stability and the best viscosity value. The research design used was a completely randomized design (CRD) with a factorial pattern with the independent variable being the concentration of rejected dragon fruit extract with four treatment levels of 0, 1.5, 3, and 4.5 grams of extract per 250 grams of soap formula and storage time consisting of four levels of 0, 7, 14, and 21 days. The best liquid soap formula was obtained when using a rejected dragon fruit extract concentration of 1.5 grams per 250 grams of soap formula (SW1 formula) with a foam stability value of more than 90% until 21 days of storage. Formula SW1 also has a stable pH during storage, which is in the pH range of 7 – 9. The viscosity value of the SW1 formula reaches 13.25 N/m2 with a free alkali value of 2.48%. The SW1 formula with a rejected dragon fruit extract content of 1.5 grams per 250 grams of soap formula can be developed as a new formula for the manufacture of liquid soap which is rich in antioxidant compounds.

Abstract

Curcumin extract from the turmeric plant is unstable to light, temperature and changes in pH, therefore it is necessary to be coated with biopolymers to have a longer shelf life. This study aims to determine the type of degradation kinetics of maltodextrin-coated curcumin and its shelf life at room temperature storage. Encapsulation was performed using an emulsion technique combined with freeze drying with the ratio of turmeric ethanol extract to maltodextrin of 7: 5 (w/w). The results showed that the efficiency of coating ethanol extract of turmeric with maltodextrin was 31.26%. Kinetics degradation of curcumin coated with maltodextrin follows zero-order reaction kinetics. Microcapsule of turmeric ethanol extract coated with maltodextrin has a shelf life at room temperature for 8.35 weeks.

Abstract

Moringa seed oil is rich in oleic acid which has benefits for treating skin health. The use of Moringa seed oil as a basic ingredient for making transparent solid soap increases the advantages of soap because it has moisturizing and skin softening properties as well as antimicrobial. The manufacture of transparent solid soap based on Moringa seed oil aims to determine the mass of Moringa seed oil which produces solid soap with the highest foam and pH stability values, as well as the level of soap irritation. The study was conducted using a completely randomized design (CRD) with the independent variable being the mass of Moringa seed oil consisting of four levels of 27.5 grams (A1), 30 grams (A2), 32.5 grams (A3), and 35 grams (A4), while the dependent variables include foam stability and pH stability which were determined after 3 weeks of testing. The best formula was further tested with a solid soap irritation level test. The best formula for transparent solid soap was found in using 30 grams of Moringa seed oil (A2) with foam stability of 93.56%, pH stability of 9-9.6, and low irritation level of only 20% after five days of use.
