Abstract

Swimming crab shells have been confirmed as umami source food waste. Information regarding the use of swimming crab shells in making seasoning in very limited. Processing the swimming crab shells into flour will cause the shell protein to hydrolyze, so that amino acids become free and give an umami effect derived from glutamic acid compounds. Umami compounds from crab shell flour can be developed into seasoning along with components of salt, sugar and pepper. This research to determine the best formula for making natural seasoning from swimming crab shells using the foam-mat drying method. A total of 5 formulas were determined based on the ratio of swimming crab shell flour to salt, that is F1 (25:45), F2 (30:40), F3 (35:35), F4 (40:30) and F5 (45:25). The parameters analyzed included physical and chemical characteristics of seasoning. The results showed that the higher addition of swimming crab shell flour had an effect on increasing levels of glutamic acid as a source of umami and the rendement of seasoning, as well as decreasing salt content, water content, solubility, and product hygroscopicity, but did not affect sugar content and water activity of the seasoning. The best formula for seasoning is F4 with a ratio of swimming crab shell flour to salt (40:30).

Abstract

Functional compounds from black rice were extracted conventionally using organic solvents, namely ethanol-distilled water and ethanol-distilled water-acid (acetic acid and a mixture of lactic acid and acetic acid) along with distilled water as control. The effectiveness of each solvent was determined by analysis of functional compounds contents (anthocyanin content, flavonoids, total phenolic, and antioxidant activity), pH value, and the resulting color characteristics. The ethanol-distilled water-citric acid solvent produced significantly higher levels of anthocyanin, total phenolic, and antioxidant activity, with the lowest extraction pH, but produced fewer flavonoids. Red-purple black rice extract has the lowest brightness. The ethanol-distilled water-citric acid solvent has the best effectiveness in the extraction of black rice functional compounds.

Abstract

Soybean sprouts and black rice have bioactive components that are beneficial for health. Both of these ingredients can be developed as functional drink ingredients. Encapsulation is one method to maintain bioactive components. This study aims to determine the total phenol content and antioxidant activity of the formula of soy sprouted milk (SKK): encapsulated black rice extract (EBH) (F1: SKK 100 %: EBH 0 %; F2: SKK 75 %: EBH 25 %; F3: SKK 50 %: EBH 50 %; F4: SKK 25 %: EBH 75 %; F4: SKK 0 %: EBH 100 %), with various coating materials: maltodextrin (MDE), Arabic gum (GA) and a mixture of MDE:GA (MGA). The results showed that the highest total phenol was obtained at F5, of all coatings: MDE (85.06 mg GAE/kg); GA (84.27 mg GAE/kg); MGA (82.49 mg GAE/kg). The highest antioxidant activity was obtained in the F3 treatment, with GA coating (58.009 % RSA). It is known that there is a tendency to increase total phenolic, in the formulation of higher concentrations of EBH. In general, MGA combined coating materials produced higher mean total phenols than MDE and GA alone. There was no tendency to increase antioxidant activity in either the formula or the type of coating

Abstract

Anthocyanins are bioactive components in black rice. Black rice anthocyanins are potent antioxidants, so they have the potential to be developed into functional food products. As a bioactive component, anthocyanins in extracts have low stability to environmental conditions such as light, temperature, and pH. Encapsulation process using the spray drying technique is known to protect and increase the stability of anthocyanin bioactive compounds. Maltodextrin (MDE) is widely used as a coating material in the encapsulation of anthocyanins using the spray drying technique with many advantages. However, skim milk powder (SMP) was found to encapsulate black rice anthocyanins efficiently. This study's general objective was to determine the effect of the ratio of MDE and SMP as an encapsulant on black rice extract powder's physical and chemical characteristics. The research method is an experimental type using a single factor Completely Randomized Design (CRD), which consisted of 6 treatments, namely the MDE:SMP ratio (100:0, 90:10, 80:20, 70:30, 60:40, and 50:50). The results showed that there was a very significant effect of the ratio of MDE and SMP on the physical and chemical characteristics of coated anthocyanin powder. MDE and SMP ratios of 50:50 resulted in coated anthocyanin powder's best physical and chemical characteristics. Keywords: Black rice extract, Coating material, Encapsulation, Physicochemical characteristics.
