Abstract

Red super dragon fruit peel (Hylocereus costaricensis) extract has capability to scavenge DPPH and the activity could be maintained by using maltodextrin as coating. The aims of the research are to determine ratio of red super dragon fruit peel ethanol extract toward maltodextrin producing microcapsule with the highest coating efficiency and DPPH scavenging content by microcapsule of red super dragon fruit peel extract. Microencapsulation was carried out using freeze drying technique. Comparison of red super dragon fruit peel extract and maltodextrin were 1: 8, 1: 10, 1: 12, and 1:14 (w / w). The results show that the highest efficiency ratio of coating extract of red super dragon fruit peel with maltodextrin was 1: 8 with percentage of 90,77%. Level of DPPH scavenging content of red super dragon fruit peel extract microcapsule with ratio of 1:8 on 5 minutes and 60 minutes each is 27.36% and 46.62%. Keywords: Hylocereus costaricensis, freeze drying, maltodextrin, microencapsulation

Abstract

Extract of super red dragon fruit peel has an antioxidant activity that can prevent free radicals from outside and its activity can be maintained by the coating of super red dragon fruit peel extract with maltodextrin The coating efficiency of super red dragon fruit peel extract with maltodextrin can be controlled with the speed of stirring during microencapsulation experiment. In order to obtain the highest microencapsulation efficiency and compare the antioxidant activity of super red dragon fruit peel extract before and after microencapsulation experiment. The study of coating efficiency has been done with microencapsulation that was carried out using the freeze-drying technique. During the microencapsulation of super red dragon fruit peel extract with freeze-drying technique, stirring speed in the microencapsulation process was 600 rpm, 800 rpm, 1000 rpm, 1200 rpm, and 1400 rpm respectively. From the microencapsulation process of super red dragon fruit peel extract coated with maltodextrin, it was obtained the highest microencapsulation efficiency at stirring speed of 800 rpm, which was 66.85% and had a particle size of 14.24 µm. It can be concluded that the antioxidant activity before and after encapsulation included a very weak category with IC50 values of 205.42 ppm for extracts and 246.32 ppm for microcapsules.

Abstract

Carotene extract from carrots (Daucus carrota L.) can improve the quality of processed noodles. Determining of carotene retention in processed carrot noodles during the storage period that has been done aims to know the reaction kinetics and shelf life of the noodles. Carrot noodles were stored for 8 weeks at room temperature and analyzed its carotene content by using a UV-Vis spectrophotometer every 7 days. The result showed that the retention of carrot noodles during storage of 0, 1, 2, 3, 4, 5, 6, 7, and 8 weeks was 53.64%, 53.19%, 52.49%, 51.68%, 51.07%, 46.30%, 45.96, 45.88, and 44.93%, respectively. The retention kinetics of carrot noodles during storage followed a zero-order reaction and had a shelf life of up to 30 weeks, 4 days, 4 hours. Keywords: carrot noodles, retention, self life

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

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

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.
