Abstract

Plastic is a commonly used packaging material due to its cheap and wide availability, especially in the food industry. However, plastic is non-biodegradable, leading to a serious problem to the environment from its widespread use. Using starch-based edible films as an alternative to plastic packaging offers a solution to this problem. As opposed to conventional methods of starch extraction for edibles, modern methods such as microwave-assisted extraction (MAE) can improve the functional properties of starchThis research aimed to determine the physicochemical properties of edible films from starch extracted through MAE. The study used a completely randomized design (CRD) with three treatments based on the amount of added starch, namely, Treatment A (3%), Treatment B (4%), and Treatment C (5%). The results from these treatments were compared against control (without MAE). Observations were conducted in triplicate, including parameters such as solubility, thickness, water holding capacity (WHC), oil holding capacity (OHC), and water content. Treatment A (3%) was found to be the best treatment, with a solubility of 76.55%, a thickness of 0.243 mm, a WHC of 38.56%, an OHC of 36.67%, and a water content of 13.79%.

Abstract

Color is the main attraction in choosing food; therefore, manufacturers do various ways to produce good colors without considering the consumer's health. Natural colors are a safe choice for health; besides being safe, natural dyes can also provide functional properties to those who consume them. The study aimed to determine the activity of natural dyes and their functional properties when mixed with chemically modified arrowroot starch. This study used a factorial design with chemical modification factor A and factor B, a ratio of dragon fruit extract to the amount of starch, with three repetitions. The best treatment was A2B3 (cross-link, starch with dragon fruit 1:2) because it had the treatment with the most visible color. This treatment has an antioxidant content of 38.95%, a polyphenol content of 106.19 mg GAE/g, a color of 76.88, and an anthocyanin content of 0.71 mg/100g.
