Abstract
This dissertation explored using fruit by-products like grape and aronia pomace as cocoa powder substitutes in whole grain cookies. An edible film made of chitosan, gum arabic, and grape seed extract was tested for its impact on nutrition, antioxidants, shelf life, and starch digestibility. Results showed successful substitution of 24 % cocoa powder, improving flavonoid content by 22%, antioxidant potential by 27-73 %, and extending shelf life by at least 30 days. Cookie consumption did not increase oxidized low-density lipoprotein receptors in healthy women. Additionally, the majority of participants (96 %) in Croatia, France and Nort Macedonia expressed their interest in purchasing environmentally friendly cookies.
Abstract (english)
Cilj ove disertacije bio je istražiti mogućnost djelomične zamjene kakao praha u receptu integralnog čajnog peciva nusproizvodima voća kao što su trop grožđa i aronije. Istraživao se i utjecaj jestivog filma na bazi kitozana i gume arabike s ekstraktom sjemenki grožđa na nutritivni sastav, antioksidacijsku aktivnost, probavljivost škroba, te produljenje trajnosti čajnog peciva. Rezultati su pokazali da nusproizvodi voća mogu uspješno zamijeniti 24% kakao praha u čajnom pecivu, a pritom doprinose povećanju sadržaja flavonoida (22%) i antioksidacijskog potencijala (27-73%), te produljuju rok trajanja za najmanje 30 dana. Umjerena konzumacija čajnog peciva ne povećava koncentraciju receptora za oksidirani lipoprotein niske gustoćekod zdravih žena. Dodatno, većina ispitanika (96 %) u Hrvatskoj, Francuskoj i Sjevernoj Makedoniji je potvrdilo interes za kupnju održivog čajnog peciva.
