Abstract

Black soybean was fermented into Tempe to increase its functional properties and bioavailability. To develop black soybean tempe into a beverage for practical consumption, sappan wood and cinnamon were added to improve the appearance and functional properties. This research aims to determine the effect of sappan wood and cinnamon addition on antioxidant levels, phenolic levels, and brightness levels of black soybean tempe beverages. The research used a Completely Randomized Design (CRD) with a ratio of sappan wood and cinnamon at 0:0, 3:0.5, 2.5:1, and 2:1.5 (%w/w). Beverage made from commercial yellow soybean tempe was used as control. This research started by making tempe using Yogyakarta's traditional method. Beans were dehulled, boiled for 30 minutes, soaked in boiling water for 36 hours, boiled again for 30 minutes, inoculated with RAPRIMA, and incubated for 40 hours at room temperature. Tempe beverage was made by milling tempe and 80°C water at 1:3 (w/w) and the barks at the mentioned ratio, followed by filtration. The beverages were then analyzed for their Ascorbic Acid Equivalent Antioxidant Capacity (AEAC), total phenolics using the Folin-Ciocalteu method, and brightness levels using the CIE method. The results showed the antioxidant properties ranged between 82.67-86.93 mg AEAC/ml, total phenolics: 53.43-66.53 mg GAE/ml, color brightness parameter L*: 33.82-34.49, a *: 1.97-2.01, and b*: 4.09-5.05. It can be concluded that adding sappan wood and cinnamon improved the antioxidant levels and appearance of black soybean tempe beverages. The highest antioxidant properties and brightness level were obtained by adding 3% and 0.5% of sappan wood and cinnamon bark, respectively.

Abstract

Black soybean germination into sprouts reportedly improved nutrition digestibility and bioactive compound content. Red dragon fruit (RDF) and egg yolk (EY) can be used as natural and halal colorants and emulsifiers. Black soybean sprout (BSS) juice made non-dairy ice cream with red dragon fruit and egg yolk as an emulsifier. This research aimed to measure the effect of various red dragon fruit and egg yolk concentrations on the characteristics of ice cream made from BSS juice. A completely randomized design was applied to six formulations made using the ratio of RDF : EY of FA (20%: 3%), FB (20%: 4%), FC (20%: 5%), FD (40%: 3%), FE (40%: 4%), and FF (40%: 5%). BSS juice was made using 48 hours of room temperature incubated sprout and water at a 1:4 (b/v) ratio. Filtrate was then mixed with sugar, cornstarch, and salt into a dough, which was then mixed with RDF and EY at various concentrations. Nutritional proximate composition, radical scavenging activity, phenolic content, total anthocyanin content, vitamin C, and sensory acceptance were analyzed. Data was then statistically analyzed using one-way ANOVA, followed by Duncan’s Multiple Range Test. Results showed that higher RDF significantly changed overrun, melting rate, increased moisture content, vitamin C (20.4 – 40.23 mg/100 g), antioxidant activity (34.9 – 62.78 % radical scavenging activity), total phenolics (0.341 – 0.536 mg/g GAE), and total anthocyanin (3.905 – 9.726 mg/kg), and hedonic score, but shorter melting time. The shortest melting time was obtained by ice cream made using 20% RDF and 5% EY, the lower concentration of fruit, and the highest concentration of egg yolk, respectively. The results indicated that BSS juice could be used as the main ingredient to make non-dairy ice cream, with red dragon fruit and egg yolk as natural colorants and emulsifiers, respectively.   Keywords: Black soybean sprout, Non-dairy ice cream, Red dragon fruit
