Sažetak
Traditional fruit varieties provide an excellent basis for the production of functional foods such as functional fruit juices (FFJ) due to their high biological value and better sensory acceptability as compared to commercial varieties. Various functional ingredients can be added to FFJ to increase their added value and thus improve health. Due to short shelf life, fruit juices are processed by thermal pasteurization, which may have negative impacts on their quality. Therefore, the application of advanced non-thermal technologies has recently been investigated, with particular attention to the "hurdle concept, " where the application of selected technologies in a specific sequence under milder processing conditions achieves a synergistic effect while assuring microbial inactivation and quality. For instance, Pulsed Electric Field (PEF) and High- Power Ultrasound (HPU) are the most promising advanced food preservation technologies in terms of energy efficiency, water savings and reduced emissions. These technologies are environmentally friendly and therefore clean, hence with less impacts on the environment than traditional technologies. Further, for the production of FFJ tailored to individual consumer needs manufacturing can employ 3D printing technology for production of 3D-printed FFJ of any geometry and composition for providing consumers with fast, high-quality and safe intake of nutrients and functional ingredients. Aforesaid approaches will promote sustainable processing of traditional (Croatian) fruit varieties and possibly enrich unique tourist offer in Croatia with fruit souvenirs. Thus, supporting basic guidelines of circular economy and tourism of the Republic of Croatia and Europe.
