Sažetak
Orange peel waste (OPW), as a by-product of citrus processing, can be efficiently valorized and used in the production of filter tea. However, during the industrial processing of this material, a large amount of powder of particle size <0.315 mm is generated, being ultimately disposed. This fraction also called herbal dust or orange peel powder (OPP) is a raw material from which a wide range of bioactive compounds (polyphenols, carotenoids, dietary fiber, sugars, essential oils, etc.) can be isolated. Ultrasound-assisted extraction (UAE) is considered as inexpensive, simple and efficient extraction technique for obtaining extracts of better and more uniform composition in a significantly shorter time and lower energy consumption. Therefore, the efficiency of UAE with an ultrasonic probe for isolation of polar compounds from OPP was examined. During the UAE process, the temperature was defined as a constant (50ºC), and the sonication amplitude (20-100%) was varied. Changes in extraction time, ultrasonic power and energy consumption were observed. Chemical composition was assesed by HPLC. The dominant compounds identified were hesperidin, naringin, narirutin and rutin. The content of all compounds was the highest at the highest amplitude (100%), with hesperidin standing out as the most dominant compound. The results show that UAE using ultrasonic probe can significantly enhance extraction of valuable compounds from plant material thus proving to be a value addition process and potentially efficient technique to be used at industrial level.
