Incorporating additives for stability of Aloe gel potentially as an edible coating

There is a rising trend in the use of edible coating for fruit, with the aim of maintaining freshness for longer, and also to improve the appearances. These applications are stimulated by the awareness created regarding food health and safety, as the substances used are incorporated with material-additive to ensure fruit quality improvement. In addition, aloe gel is one of the potential natural edible coatings, known to contain numerous functional bioactive compounds. The aim of this research, therefore, was to determine the consequence and influence of incorporated additives (e.g., citric acid, ascorbic acid, potassium sorbate and sorbitol) on aloe gel (Ecogel) pottentially as an edible coating during storage. This research applied a completely randomized design, and the results showed a positive effect of additives. Meanwhile, the initial composition of Ecogel include 98.46% of water, 1.08% carbohydrate, protein 0.037%, fat 0.28%, ash 0.22% and pH 4.7. The degree of stability with the incorporation of ascorbic acid extended for 6 day. This is observed from the variable of color difference (∆E) 11.30, Chroma (C*) 2.81, transparency 80.34 and the supporting attribute of water content (99.13%), 96 mPa viscosity, pH 3.87, and color visually (clear white-yellow)
