Sažetak
Effect of malaxation time and temperature on Levantinka virgin olive oil (VOO) properties during production process was studied. Mixing of olive pastes was performed at 26, 36, 46oC. Also, for every temperature effect, malaxation time was studied during 30, 45, 60 min. In order to estimate the olive oil quality the investigation of free fatty acid, peroxide value, UV spectrophotometric indices, total phenols content, sensory evaluation, oxidative stability and antioxidant activity was carried out. It’s evident that both, malaxation time and temperature, affect the properties and quality of olive oil obtained. The lowest peroxide value, the highest total phenols content and DPPH value was achieved at 36oC and 30 min. The lowest free fatty acid and the highest oxidative stability was also achieved at the same temperature (36oC) but at some longer malaxation time (FFA 60 min, Rancimat test 45 min). The values of K-numbers were within the limits for VOO for all samples processed at 26oC and 36oC and 30 and 45 min, respectively. Sensory analyses of investigated oils showed the highest score for those processed at same malaxation conditions as for K-numbers. The highest bitterness was perceived in samples obtained at 36oC and 30 min of malaxation time while pungency in samples produced at 36oC and 60 min of malaxation time.
