Sažetak
Ulva lactuca is a green macro alga also known as “sea lettuce” belonging to the genus Ulva in which about 50 other species have been described. Due to the high content of biologically active molecules (BAM), Ulva lactuca is considered not only as food but also as a dietary supplement. Extraction is a fast and efficient method of separation and concentration of BAM which differ in chemical structure. For each matrix it is necessary to optimize the extraction conditions considering all the extraction parameters: the availability of the extraction technique, the purity of the extract, the extraction yield and the energy consumption (Rostagno & Prado, 2013). The advantages of new extraction techniques manifest in the extraction rate and yield, lower energy consumption and environmental acceptability when compared to conventional techniques. Therefore, the aim of this study was to optimize the parameters of ultrasound-assisted extraction (UAE) in order to achieve the maximum yield of carotenoids and chlorophylls as well as antioxidant activity (AOA) from alga U. lactuca using two solvents (hexane and 80% acetone) at two temperatures (30 and 50 ºC) and three different times (10, 15 and 20 min).
