Abstract
S porastom problema zbrinjavanja otpada i razgradnje plastične ambalaže raste i interes današnjih istraživanja k upotrebi biorazgradivih materijala. Među njima jestivi biofilmovi s visokovrijednim funkcionalnim sastojcima izoliranim iz različitih nusproizvoda prehrambene industrije svakako zauzimaju značajno mjesto. Sukladno današnjim trendovima u razvoju biorazdradivih materijala, i ovo istraživanje je pokazalo razvoj novih funkcionalnih pektinskih biofilmova s dodatkom ekstrakata kore mandarine. Njihova ugradnja u pektinske biofilmove praćena je promjenama u kemijskim i fizikalnim svojstvima. Rezultati su pokazali da biofilmovi s fenolnim ekstraktima kore mandarine pokazuju porast intenziteta boje, vlačne čvrstoće, te smanjenja modula elastičnosti u odnosu na biofilmove bez ekstrakata. Time je pokazano da se ekstrakti kore mandarine mogu uspješno primijeniti za izradu ekoloških prihvatljivih funkcionalnih pektinskih biofilmova.
Abstract (english)
With the increases of waste disposal problems and decomposition of plastic packaging, the interest of nowadays investigations for the use of biodegradable materials is growing. Among them, edible biofilms with high-value functional ingredients isolated from various by-products of the food industry certainly occupy a significant place. In line with today’s trends in the development of biodegradable materials, this research has also shown the development of new functional pectin biofilms with the addition of tangerine peel extracts. Their incorporation into pectin biofilms is accompanied by changes in chemical and physical properties. The results showed that pectin biofilms with added phenolic extracts of tangerine peel have increased color intensity, tensile strength, but decreased the moduls of elasticity in comparison with biofilms without extracts. In this regard is showed that tangerine peel extracts could be successfully implemented for production of environment friendly functional pectin biofilms.
