Preparation of a novel biodegradable film by co-fermentation of straw and shrimp shell with Aureobasidium pullulans and Photobacterium sp. LYM-1

Development of antioxidant film based on gelatin and carboxymethylcellulose incorporated with Tecoma stans (L.) Juss. ex Kunth Petals extract for biodegradable food packaging

“…Approximately 0.10 g of each film sample was soaked and continuously shaken in 10 mL of pure ethanol for 10 min to extract the antioxidant from the blend films. A 3 mL of film extract was mixed with 1 mL of 0.1 mM ethanolic DPPH solution, followed by incubation at room temperature in a dark area for 30 h. The absorbance of the mixture was investigated at 517 nm against ethanol as a blank solution, and the DPPH radical scavenging activity of the blend film was measured in three repetitions and determined using the following Equation (1).…”

“…A DPPH × 100 (1) Where, ADPPH is the absorbance of the DPPH solution, and A sample is the absorbance of the film sample extract…”

“…Synthetic plastic packaging was exploited and accumulated in the ecosystem at an incredible rate of several tons annually. To overcome this problem, environmentally friendly materials have attracted much attention as an alternative to lowering the environmental impact of petroleum-based plastic food packaging [1]. Bio-based active packaging is a feasible candidate to replace synthetic plastic due to its versatility, non-toxic, low cost, and eco-friendly.…”
