|Abstract(s):||Nowadays there is an increasing interest in identifying antioxidant properties in products from natural sources to be used e.g. in food preservation or in health-enhancing foods. Edible films can provide additional protection for food, while being a fully biodegradable. environmental friendly packaging system. They can be used to improve food quality and prolong shelf-life of fresh products and they can be used to carry functional ingredients such as antioxidants, antimicrobials, nutrients, and flavours to further alliance food stability, quality, functionality and safety.1-2 Some publications reported that seeds could be considered a valuable source of phenolics, possessing beneficial activities such as antioxidant, anti-carcinogenic, antimicrobial, anti-mutagcnic and anti-inflamatory.3 Previous publications have already used galactomannans from commercial and non-traditional origins as a source for films and coatings production.'" The present work had three objectives: to evaluate the total phenolic content and antioxidant properties of ethanolic and water extracts from G. triacanthos seeds: to demonstrate whether galactomannan films are suitable to incorporate antioxidant compounds for further application in the food industry: and to show how the main film properties can change with galactomannan and extract concentrations.|
