### Red Fruits and Grape
Strawberry, raspberry, blueberry, and blackberry pomaces have been evaluated for their content in polyphenols, and authors showed that, among these, blueberry byproduct has the highest content of extractable flavonoids (17.10 mg/g), anthocyanins (509.13 mg/g), and proanthocyanidins (34.33 mg/g), followed by blackberry (2.91, 25.17, and 20.66 mg/g, respectively) and strawberry (3.26, 15.98, and 19.70 mg/g, respectively) [145]. Overall, the phenolic profile of pomaces resembles those of fresh fruits. Regarding other valuable constituents, the analysis of fatty acids content of wild strawberry, blueberry, blackberry, and raspberry showed an average content of FFAA of 27.3%, and the qualitative profile was dominated by mono- and polyunsaturated FFAA, with linoleic acid, oleic acid, and \(\alpha\)-linolenic being the most representative [97]. Considering the value of berry and grape byproducts as sources of nutrients and polyphenols, a massive volume of works dealing with the extraction of these classes of compounds from pomace has been published during the last decade. An exhaustive overview of these works can be found in recent review papers [143; 146; 147]. Green Extraction of Bioactive Compounds from Red Fruit and Grape Pomace  
Recently, scCO\({}_{2}\) has been widely employed for the extraction of the apolar fraction of berry pomace, consisting mainly of fatty acids contained in the seeds. As an example, an optimized SFE-CO\({}_{2}\) extraction protocol allowed the extraction of the lipophilic fraction of blackcurrant pomace with a yield of 14.6%, and this extract was rich in polyunsaturated fatty acids such as linoleic (46.89%) and \(\gamma\)-linolenic (14.02%) acids, and tocopherols (in total, 2468 \(\upmu\)g/g oil) [69]. Similar results were obtained from a more recent work, where the same extractive approach was used to extract the lipophilic fraction of elderberry pomace, leading to a yield of 14.05%. This extract was also rich in polyunsaturated linoleic (42.0%) and \(\alpha\)-linolenic (34.1%) fatty acids [148]. [PERSON] et al. obtained oils enriched in PUFAs (66.8%-75.9% \(w/w\)), vitamin E (range: 113.0-241.8 mg/100 g oil), and carotenoids (range: 11.5-32.3 mg/100 g oil) from SFE-CO\({}_{2}\) of blackcurrant seeds, and this composition was positively correlated to its antioxidant activity observed in vitro [149]. A huge amount of work dealing with green extraction of phenolics from berry and grape pomace can be found in the literature, where the application of different extraction techniques is reported (Table 2). As an example, the group of [PERSON] et al. used PEF and UAE to extract anthocyanins and other polyphenols from blueberry pomace, using alcohols (methanol and ethanol) as solvents. The highest total polyphenols content (TPC) [10.52 mg of gallic acid equivalent (GAE) per g of dry weight (dw)] and antioxidant activity (AA) (0.83 mmol TE/g dw) were obtained by PEF-assisted extraction in the ethanol-based solvent after 100 pulses and 20 kV/cm, which corresponds to an energy input of 41.03 kJ/kg. A total of eighteen individual polyphenols were identified in all investigated blueberry pomace extracts, using high-performance liquid chromatography with the diode-array detector (HPLC-DAD) (JASCO International Co., Ltd., Tokyo, Japan) and liquid chromatography electrospray ionization tandem mass spectrometry (LC-(HESI)-MS/MS) (Thermo Scientific Inc., San Jose, CA, USA). The highest anthocyanin (1757.32 \(\upmu\)g/g of dw) and flavanol (297.86 \(\upmu\)g/g of dw) yields were obtained in the methanol-based solvent, while the highest phenolic acid (625.47 \(\upmu\)g/g of dw) and flavonol (157.54 \(\upmu\)g/g of dw) yields were obtained in the ethanol-based solvent by PEF-assisted extraction at the energy input of 41.03 kJ/kg [150]. In another recent work, [PERSON] et al. used an aqueous EAE (AEAE) to simultaneously recover lipophilic compounds and polyphenols from raspberry pomace, testing different combinations of carbohydrates and proteases [70].
