This study aimed to evaluate the effect of the ratio of gatot and red beans usage on water content and organoleptic characteristics from "Gatotkaca" analog rice. The material in this study was gatot (fermented cassava) and red beans. The experimental design used was a completely randomized design (CRD) with 4 treatments and 5 replications. This study consisted of 4 different analog rice formulations, namely T1 (90% gatot: 10% red beans); T2 (85% gatot: 15% red beans); T3 (80% gatot: 20% red beans); T4 (75% gatot: 25% red beans). Data were analysed using Analysis of Variance (ANOVA) with the significance level 5%. The results showed that the difference in the ratio of the usage of gatot but red beans didn’t have a significant effect (p>0.05) on the water content and organoleptic characteristics. Treatment with a ratio of gatot and 85% red beans  15% gatot was the best treatment.

This research aims to determine the effect of High Fructose Syrup (HFS) addition to carbon dioxide (CO2) content, ethanol content and organoleptic properties of green coconut water kefir, and to determine the ideal HFS concentration for green coconut water kefir. Complete Randomized Design is used in this research with 5 treatments and 4 replications i.e. T0 (0% v/v HFS), T1 (2.5% v/v HFS), T2 (5% v/v HFS), T3 (7.5% v/v HFS), and T4 (10% v/v HFS). The CO2 content is measured by sodium carbonate (Na2CO3) titration, ethanol content is measured by distillation, while the organoleptic properties that included level of sourness, level of sweetness, soda sensation, sour aroma, and viscosity are done by 25 panelists. The results show that the addition of HFS is statistically gave significant effect to the CO2 content and organoleptic properties (P<0,05). However, the ethanol content, which analyzed using empirical model of quadratic polynomial regression, show that the addition of HFS is incompatible to the ethanol content of green coconut water kefir. The most optimal HFS concentration is 7.5% v/v, resulting CO2 content of 0.096%; ethanol content 1.545%; and desirable organoleptic properties, which are low level of sourness, high level of sweetness, very high soda sensation, low sour aroma, and high viscosity.

Antioxidant Activity of Extract from Ultrasonic-Assisted Extraction of Durian Peels 超声辅助提取榴莲皮提取物的抗氧化活性研究
Pub Date : 2018-12-05 DOI: 10.17728/JAFT.3309
Bambang Kunarto, E. Sani
The increase in durian production results in the accumulation of durian peel waste. The bioactive component of durian peel has the potential to be used as an antioxidant. Thus, there is a need to carry out an extraction process to obtain  bioactive compounds from durian peel. However, conventional extraction methods cause damage to phenolic compounds due to oxidation, hydrolysis and ionization reactions during the extraction process. Therefore, durian peel extraction was carried out using ultrasonic assisted extraction method (UAE) in this study. The purpose of this study was to investigate the effect of varying ratios of durian peel to ethanol solvents and extraction time on the yield, total phenolics content, total flavonoids content and antioxidant activity. The results of the research data were analyzed using a two-factor completely randomized design, which included variations of the ratio of durian peel to ethanol solvents and extraction time The Duncan’s New Multiple Range Test (DNMRT) was carried out as a follow up test to determine the differences in each treatment at a significance level of 0.05. The results showed that the best treatment for peel extraction using ultrasonic assisted extraction was a 1: 9 ratio of durian peel to ethanol at an extraction time of 20 minutes. The extraction of durian peel under this condition gave the highest yield of 12.77 ± 0.16%, antioxidant activity (IC50) of 38.33 ± 0.12 ppm, total phenolic content of 63.30 ± 0.08 mgGAE / g and total flavonoids content of 47.53 ± 0.48 mgQE / g. In addition, total phenolics content and total flavonoid content showed a strong correlation to the antioxidant activity of durian peel extract.
榴莲产量的增加导致榴莲皮废料的积累。榴莲皮中的生物活性成分具有用作抗氧化剂的潜力。因此,需要进行提取工艺以从榴莲皮中获得生物活性化合物。然而,传统的提取方法在提取过程中由于氧化、水解和电离反应而对酚类化合物造成损害。因此,本研究采用超声波辅助提取法(UAE)提取榴莲皮。本研究的目的是研究不同比例的榴莲皮与乙醇溶剂和提取时间对产量、总酚含量、总黄酮含量和抗氧化活性的影响。研究数据的结果采用双因素完全随机设计进行分析,其中包括榴莲皮与乙醇溶剂的比例和提取时间的变化。Duncan’s New Multiple Range Test(DNMRT)作为随访测试,以确定每种处理的差异,显著性水平为0.05。结果表明,超声波辅助提取榴莲皮的最佳处理方法是榴莲皮与乙醇的比例为1:9,提取时间为20分钟。在此条件下提取榴莲皮的最高产率为12.77±0.16%,抗氧化活性(IC50)为38.33±0.12ppm,总酚含量为63.30±0.08mgGAE/g,总黄酮含量为47.53±0.48mgQE/g。

Basil contains flavonoid, saponin, tannin, and essential oils namely sineol and eugenol. Basil has been known as appetite stimulant, laxative, fragrance, and breast milk stimulator. This study aimed to determine the effect of basil addition to linear expansion, crispiness, color, and organoleptic of basil cracker. Complete Randomized Design was used in this research with 4 treatments and 5 replications i.e. T1 (10% basil, 90% tapioca), T2 (15% basil, 85% tapioca), T3 (20% basil, 80% tapioca), T4 (25% basil, 75% tapioca). Linear expansion was measured using ruler, hardness/crispiness using texture analyzer, color using digital colormeter, and organoleptic testing was done by 25 panelists. The research showed that basil cracker had linear expansion of 166-235%; hardness of 1264.8-1837.6 gF; L* value of 22,47-40,40 and a* value of -20.73 to -12.67. Variation of basil proportion gave significant effects to linear expansion, crispiness, and color of basil cracker. The best treatment was T2 (15% basil, 85% tapioca) because it had high linear expansion and bright color, was crispy, and preferred by panelists.
