This study aimed of this study was to find out how carrageenan affected the physical, chemical, and consumer preference characteristics of an albedo sheet jam combination made from red dragon fruit and watermelon. Four amounts of carrageenan addition— 0%, 1%, 1.5%, and 2%; three repeatations; and a one-factor Completely Randomized Design (CRD)—were employed in this investigation. Analysis. The sheet jam's texture, color, water content, total dissolved solids, reducing sugars, antioxidant activity, Vitamin C concentration, and hedonic tests were all examined after that. The SPSS program is used in statistical data processing to perform one-way analysis (one-way ANOVA). Using the Duncan approach, more study was conducted to determine the variations between treatments. The hedonic test was used to identify the chosen sheet jam formulation, which also included the inclusion of 1% carrageenan concentration, and the following quality test findings were obtained: Lightness (L) 20.19, redness (a*) 7.11, yellowness (b*) -1.87, texture 652.15 N/mm2, water content 18.28% wb, total dissolved solids 21.29% 0 brix, reducing sugars 46.35%, antioxidant activity of RSA 19.32%, and vitamin C 9.14 mg/100 g

The Effect of Foaming Agent and Whipping Time on Albedo Characteristics of Watermelon Flour

The fruit's rind is one of the natural waste products that can support nutrients like carbohydrates, proteins, and lipids. Reused rind contributes significantly to the effective handling of this fruit's byproduct. Processing watermelon rind into powder by lowering water content and activity is an alternative to extending its shelf life. The flour form is easier and more suitable for application in multiple processing food products such as snacks, beverages, bread, and pasta. The focus of this study was to verify the optimal state for foam mat drying using concentrations of foaming agent in the form of egg albumin (10, 15, 20), foam stabilizer in the form of CMC with concentrations of 1 %, and whipping time (5, 7, and 9 minutes) on for bulk density, WSI, hygroscopicity, L* value, a* value, b* value of total phenol and antioxidants activity, and the maximum antioxidant content of watermelon albedo flour using Completely Randomized design with 2 factorial resulting in nine treatments with three replications. Based on the outcome, the bulk density of the resulting watermelon albedo flour ranges from 0.25-0.50 gr/cm-3 and 0.11-0.26%. of WSI; 22.63-28.18g/100g-1 of hygroscopicity; 1.92-4.67% of total phenol; 47.48-66.59% of L*value; 3.74-6.11% of a*value; 5.47-16.08% of b*values and 6.80- 25.26% RSa of antioxidants activity. The best treatment for antioxidant activity was 25.26% RSA using 10% of the foaming agent and whipping time in 9 minutes. These findings have implications for the food industry because they suggest that treatments can influence the properties of watermelon albedo flour

The Impact of Various Concentration of Maizena Flour on the Physicochemistry and Organoleptic Properties of Petis

Shrimp is a fishery product that has a specific aroma and has a high nutritional value. Petis derived from the body fluids of fish or shrimp through a prolonged boiling process so that it becomes denser like pasta. This study aims to determine the influence of cornstarch concentration as a binder and filler material for physical, chemical and organoleptic characteristics of shrimp petis. A Completely Randomised Design was used, with 1 factor, namely the concentration of maizena flour with 5 treatments, namely P0 (100 g shrimp broth and 0 g maizena flour); P1 (100 g shrimp broth and 2 g maizena flour); P2 (100 g shrimp broth and 4 g maizena flour); P3 (100 g of shrimp broth and 6 g of maizena flour); P4 (100 g shrimp broth and 8 g maizena flour) and 4 replications. The results showed that the treatment had an effect (p <0.05) on all observation variables i.e., chemical properties (water content, ash content, protein content), physical properties (viscosity), and organoleptic properties (taste, color, aroma, and texture). The P3 treatment was chosen as the best treatment because it approached the quality requirements of shrimp paste according to SNI (Indonesian National Standard) with characteristics of water content 48.29%, ash content 1.10%, protein content 20.95%, viscosity 91.01 Cp, and taste organoleptic 4.50 (rather savory), color 4.10 (dark), aroma 1.85 (rather fishy), and texture 4.05 (thick)
