A biosensor was developed by immobilizing laccase onto mercury thin film electrode (MTFE) by means of gelatin that is then crosslinked with glutaraldehyde. Mercury thin film (MTF) was deposited onto glassy carbon electrode (GCE) and the obtained biosensor was utilized for the determination of phenolic compounds. The measurement was based on the amperometric detection of oxygen consumption in re...

Biodegradable films with antioxidant properties have been studied in recent years. Curcumin is a polyphenol chemical obtained from turmeric extraction (Curcuma longa L.) with a range of biological activities. The objective this work was to determine diffusion coefficient of curcumin in the edible films based gelatin and yam-starch matrixes. The diffusion coefficient was determinate by Fluoresce...

Abstract The food packaging sector is focused on developing innovative materials to enhance safety and quality while reducing environmental impact. Accordingly, this study aimed develop based bovine gelatin (G) blended with crude sweet orange juice pomace pectin (SOPP) at different ratios (G/SOPP = 85/15, 65/35, 50/50, w/w). obtained SOPP was highly methylated exhibited antioxidant antibacteria...

Preserved eggs are prone to lose water during storage, which causes the preserved shrink and have poor taste, bad flavor, reduced quality. By studying a degradable coating agent applying it eggs, we explored its effect on quality of storage. In this paper, structure performance gelatin film (GF), gelatin–bacterial cellulose (GBF), cellulose–MgO nanocomposite (GBMF) were by adding bacterial (BC)...

The use of plastics is resisted worldwide. Therefore, finding alternatives to plastic packaging products an urgent issue. This work was dedicated the preparation biodegradable composited films with potato starch, glycerol, and gelatin. formulation film first optimized via response surface methodology combined multi-index comprehensive evaluation method that considered physical properties (thick...
