Abstract

Red dragon fruit contains anthocyanins which act as natural dyes with a purplish red color. The purpose of this study was to determine the characteristics of red dragon fruit as a raw material for natural coloring pigments and to determine the effect of blanching on the characteristics of the red dragon fruit pigment ethanol extract. The study was conducted using a laboratory experimental method using a completely randomized design (RAL) with a single factor, namely blanching time. The blanching time is denoted by 1 (0 minutes), 2 (3 minutes), 3 (5 minutes) and 4 (7 minutes). Data from research results related to red dragon fruit are presented in tables and analyzed descriptively, while data from ethanol extract of red dragon fruit pigments were analyzed by linear regression analysis. The results showed that the pH of the raw material characteristics was highest in the fresh treatment and the lowest in the blanching treatment. The results of the highest lightness, redness and yellowness were obtained in the blanching, blanching and fresh treatments, respectively. While the lowest values ​​were in the fresh, fresh and blanching treatments. The highest total dissolved solids yield was in the fresh treatment and the lowest was in the blanching treatment. Blanching treatment has an effect on yield, reddish color, total dissolved solids and has no effect on pH, color intensity and color lightness.

Abstract

Biodegradable foam is a type of environmentally friendly packaging made from biopolymers in the form of starch that can be degraded naturally. This study aims to determine the characteristics of biodegradable foam and its prototype made from cassava starch as a biopolymer substitute for synthetic polymers by adding variations of bagasse flour to compact the structure and polyvinyl alcohol (PVA) which functions to reduce water absorption. The stages of making biodegradable foam are started by making bagasse flour, making biodegradable foam sheets using the baking process, and making a prototype bowl of biodegradable foam. The making of this biodegradable foam consists of 6 formulas by adding variations of bagasse flour (5%, 10%, 15%) and PVA (20%, 40%) from 36 grams of starch mass. The tests carried out were in the form of water absorption, biodegradation, thickness, tensile strength, and density tests. The best treatment was found in the A3B1 formula which was used as the basis for making a prototype bowl of biodegradable foam. The addition of variations of bagasse flour and PVA had a significant effect on the characteristics of water absorption and biodegradation, while the other characteristics were only PVA which had a significant effect. The results of the best treatment as the basis for making a prototype bowl of biodegradable foam with water absorption characteristics of 25.93% and biodegradation of 45.95%.

Abstract

Dyes made from natural ingredients sourced from animals and plants are used as food coloring. One of the natural green dyes is obtained from leaves that contain chlorophyll. One of the leaves that can be used as a dye is mustard greens because it contains chlorophyll. The purpose of this study was to analyze the mass balance in the process of making mustard leaf (Brassica rapa var. parachinensis L.). This research was conducted using laboratory experimental methods. The production of natural dye powder for mustard leaves is carriec out by means of material preparation,washing, blanching, extraction, addition of MgCO3 powder making and size reduction. The process ofmaking mustard leaf natural dye using mustard leaf 100 g, MgCO3 0,14 g, Tween 80 3,5014 g, and maltodextrin 35,014 g result in 33,8 g of dye powder. The mass balance of the process of making mustard leaf natural dye produces a final yield of 24,40%, the efficiency of the process in the powder making process is 0,087 (100%) with the highest mass loss in the blanching of 1.032 g.
