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

The aim of this research is to determine the shelf life of seasoning of swimming crab shell in metalized packaging, which is stored at various temperatures using the Arrhenius modeling. Seasoning are packaged using metalized packaging with a thickness of 0.06 mm, which is stored at 25ºC, 35ºC, and 45ºC for 8 weeks with 75% humudity. The parameters used for measuring shelf life are initial moisture content, critical water, and changes in water content during storage. In addition, analysis of hygroscopicity and water activities (aw) value of seasoning as supporting parameters were also carried out. The results showed that seasoning that the seasoning of the swimming crab shells was classified as a hygroscopic product, had moisture content, and aw values a low during storage. The longest shelf life of the swimming crab shell seasoning is storage at 25ºC, reaching 62 weeks based on moisture content parameters.

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
