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...
Starch is the most abundant biomass and potential replacement of single-use packaging; however, lack water durability wet strength restrict applicability starches. Hemiacetal/acetals cross-linked starch film have stability, possess poor owing to crystallinity. In this study, we prepared TEMPO-oxidized cellulose nanofiber (TCNF)/starch composite films by mixing different-storage-duration native ...
Increasing environmental awareness has promoted an interest in alternative strategies to common plastics obtained from fossil sources, stimulating research on the use of biodegradable and edible films/coatings renewable sources such as arrowroot starch. This work aimed evaluate starch formation films coatings. concentration (from 1% 5%, mass/mass) film produced by casting resulted increased wat...
Graft polymerizations of vinyl acetate onto granular corn starch were initiated by cobalt-60 irradiation of starch-monomer-water mixtures. and ungrafted poly(vinyl acetate) was separated from the graft copolymer by benzene extraction. Conversions of monomer to polymer were quantitative at a radiation dose of 1.0 IvIrad. However, over half of the polymer was present as ungrafted poly(vinyl aceta...
The large consumption of biodegradable films from cassava starch acetate (FCSA) as ingredients in food and pharmaceutical products requires the assessment of the possible toxicity of these products. The aim of this study was to investigate the toxicity of biodegradable film from cassava starch acetate after oral exposure of Wistar rats for 90 days. The amount of food consumed and the body weigh...
