“…Previously conducted optimization of polyphenols obtained via UAE from blackcurrant and redcurrant pomaces revealed that the optimal ultrasound amplitudes and times were 51% in 3 min and 91% in 11 min for blackcurrant and redcurrant, respectively [ 24 ]. Silva et al [ 25 ] optimized the ethanolic UAE of polyphenols from acerola waste and a reported similar extraction time—13.6 min—to be the most efficient in terms of TPC, total flavonoid content and antioxidant capacity, as measured in a DPPH assay.…”

“…UAE was performed using the previously reported method [ 24 ] in a UP400S ultrasound processor (Hielscher Ultrasonics, Teltow, Germany) with an output power of 400 W. For every sample, two grams of pomace were placed in a falcon tube and filled with distilled water at a solid/liquid ratio of 1:15 shortly before extraction. To maintain a temperature below 45 °C, the falcon tube was immersed in an ice bath.…”

An investigation of the ultrasound-assisted extraction (UAE) of polyphenol-rich aqueous extracts from blackberry, chokeberry and raspberry pomaces was carried out. The aim of the study was to choose optimal conditions for UAE in order to obtain extracts rich in phenolic compounds. The optimization was carried out based on response surface methodology. The variable conditions were amplitude of ultrasound wave and extraction time, whereas responses were total polyphenol content and antioxidant capacity. Based on the ANOVA analysis, mathematical models were fitted and verified. The most effective conditions of amplitude and time were 98% and 5.00 min, 78% and 10.32 min and 90% and 11.56 min for blackberry pomace, chokeberry pomace and raspberry pomace, respectively. The actual results obtained in optimized conditions were comparable to the results predicted by the models. Additionally, the anthocyanin content in extracts was determined in the high-performance liquid chromatography assay. It was proven that response surface methodology could be a useful tool in the optimization of UAE processes for obtaining polyphenol-rich extracts from berry fruit pomaces.

Berry fruit seeds which are considered as a fruit industry waste product can be a source of oil with unique chemical, physical, and nutritional properties. The blackberry, chokeberry, and raspberry seeds can be perceived as an alternative source of oil. However, conventional oil extraction is merged with financial and environmental expanses. Therefore, alternative extraction methods, ultrasound-assisted, for example, are being gradually introduced to the common practice. The aim of the following study was to determine the optimal conditions of ultrasound-assisted extraction of oil from blackberry, chokeberry, and raspberry seeds in order to obtain oil with high yield and improved oxidative stability. The variables of the experiment were extraction time and ultrasound amplitude. Based on the results, the mathematical models were fit, and optimum conditions of time and amplitude were calculated: 8.20 min and 72.98%, 10.11 min and 59.18%, 8.43 min and 95.57% for blackberry, chokeberry, and raspberry seed oils, respectively. Additionally, oils obtained in the optimized conditions were assessed in differential scanning calorimetry study to evaluate their melting and crystallization characteristics. The results showed that ultrasound application affected thermal properties of oils only slightly. The evaluation of oxidation kinetics led to the conclusion that ultrasound may cause an activation energy increase. Also, the profile of fatty acids and their distribution in triacylglycerol molecules were studied. The output values of experiments were comparable between oils obtained from the same berry seeds. All of the oils were characterized with a high share of polyunsaturated fatty acids (over 70%) with predominant content of linoleic acid. Summarized results show that the ultrasound technique can be successfully applied in the oil extraction procedure. The benefits contain improved yield, longer oxidation induction time, and invariance of the specific oil chemical and physical properties.
