Defatted raspberry seeds were used as an alternative source of antioxidants and ellagic acid (EA) extracted using Natural deep eutectic solvents (NADES). In the preliminary study, the best NADES combination (citric acid-betaine) and the most influential variables (temperature, time, and NADES/plant ratio) were selected for the further optimization process. All samples were analyzed in terms of total polyphenol, EA content, and antioxidant activity. Two sets of optimal conditions were generated by response surface methodology. The first set (Opt1) was designed for higher conversion of ellagitannins to EA while the latter set (Opt2) for higher EA content/100 g extract. Opt1 and Opt2 had higher values for all investigated responses compared to 80% ethanolic extract but had a lower conversion rate of ellagitannins to EA compared to acidified methanol extract. The third set of parameters (Opt3) selected beyond the initial experimental domain was used to obtain a sample with the highest EA content/100 g extract. Due to their nature, NADES extracts are ready to use and could have various technological roles in products since they are antioxidants, acidifiers, and colorants. NADES raspberry extracts exhibited higher anti-proliferative activity compared to ethanolic extracts in terms of EC50 values. However, the main contributor of anti-cancer activity in NADES raspberry extracts were individual NADES compounds and/or their newly formed NADES structure.

“…A total of 63 volatile substances were identified, including 7 chemical classes of volatile substances: hydrocarbons (21), esters (6), aldehydes (6), alkenes (4), ketones (8), PCA reduces the dimensionality of the E-nose data, while the LDA is a statistical method that uses the signals of all sensors to study the category of samples [30]. Figure 1F is a PCA two-dimensional image of four seed oil E-nose data.…”

“…A total of 63 volatile substances were identified, including 7 chemical classes of volatile substances: hydrocarbons (21), esters (6), aldehydes (6), alkenes (4), ketones (8), alcohols (6), acids (3), and others (9) (Table 3). This was similar to the results of seed oil volatile flavor components reported in golden melon seeds [31], camellia seeds [33], and sesame seeds [34], which reflects that the scent of the seed oil is not reflected by one or several compounds, but by the synergistic effect of multiple components to reflect different characteristic scents.…”

Field muskmelon seed oil was extracted by press extraction (PE), Soxhlet extraction (SE), organic extraction (OSE), and aqueous extraction (AE). The oils were then evaluated for their physicochemical properties, fatty acid composition, volatile compounds, and antioxidant properties. A high yield oil was found in the SE sample. The AE sample had the highest elevated acid and peroxide values, while PE and OSE had the highest oil iodine content. The oil samples did not differ significantly in their fatty acid profile depending on the extraction method. However, E-nose, HS-GC-IMS, and HS-SPME-GC-MS showed that the flavor composition of the four samples was significantly different, attributed to the changes in the composition and content of the compounds caused by the different extraction methods. Furthermore, the strongest FRAP and the free radical scavenging ability of DPPH and ABTS+ showed in the SE sample. In general, SE’s seed oil has certain advantages when applied to the muskmelon seed oil industry.

“…The only drawback of these green methods is that higher extraction yields are obtained with solvent extraction than SFE [ 19 ]. The advantages of working with SFE and cold-pressing are reduced solvent use, lower energy consumption, shorter extraction time and better quality [ 20 ]. There is still a need to utilize more novel and green techniques to the waste materials to achieve higher biologically active compounds retrieval rates.…”
