Antioxidant properties of carrageenan films with addition of orange essential oil
Original language description
The main aim of this research was to prepare edible films consisting of carrageenan, trehalose and orange essential oil with the addition of emulsifiers (Tween 20, Tween 80) and characterize their antioxidant properties by DPPH (2,2-diphenyl-1- picrylhydrazyl) and TPC (total polyphenol content) by Folin-Ciocalteau method. There were found that the addition of essential oil does not have a high impact on polyphenol content and antioxidant activity, but the best results were found when the trehalose was combined with orange essential oil and Tween. Total polyphenol content was 4.55 +- 0.16 mg gallic acid/g of sample and DPPH was 4.14 +- 0.15 % and 4.55 +- 0.09 %. It can be stressed out, that addition of essential oil into matrices of edible film has no so high impact on antioxidant properties, but the potential usage is also as the antimicrobial agent or with trehalose as a preserving of color and aroma of packaged food.
