“…Accordingly, it can be concluded that these three eutectic solvents present the best performance for the extraction of carotenoids from pumpkin. Although DL-menthol based NADES had already been showed to be good solvents for carotenoids extraction [27] , in this work better results were achieved using fatty acid based NADES. This could be explained by the polarity of dominant carotenoids in pumpkin (β-carotene-nonpolar, β-cryptoxanthin and lutein even more polar) [28] .…”

“…The optimal parameters for β-carotene maximization were extraction temperature of 50 °C, ultrasonic power of 60% (52.5 W/cm 3 ) and solvent to solid ration of 7 mL/g during the 10 min for carotenoids extraction from pumpkin reaching β-carotene content of 151.41 ug/mL. By choosing the low temperature (50 °C) and short extraction time it is avoided high oxidative degradation and isomerization of carotenoids and the generation of free radicals which can be triggered by high temperatures and cavitation [27] . Selected condition should be easily applicable with the low-cost demands also on the others food sources or food by-products rich in carotenoids, precisely of β-carotene.…”

“…They found that the increase in β-carotene content extraction with the increase of ultrasonication can be attributed to the cavitation phenomenon induced by ultrasound. On the other hand, the use of enzymes in UAE has become widespread to perform the extraction process more effectively and quickly in recent studies (Ricarte et al, 2020;Umair et al, 2021;Gao et al, 2022;Suo et al, 2023). In this sense, the synergistic effect resulting from the using enzymes led to the highest amount of carotenoids being attained in the extracts obtained through the UAEE method.…”

Nowadays, there is a growing interest in fully utilizing agro-industrial wastes, with carotenoids gaining attention as valuable coloring agents. One of the potential sources for carotenoid extraction is lemon peel. The purpose of this study was to determine optimal extraction techniques for extracting as much carotenoids as possible from lemon peel. In this context, a comparison was conducted among extracts obtained via conventional, ultrasound-assisted (UAE), and ultrasound-assisted enzymatic (UAEE) extraction methods. The highest carotenoid content (0.792±0.01 mg/L) was achieved with UAEE, while the lowest (0.493±0.01 mg/L) was obtained conventionally. UAEE exhibited the highest antioxidant activity values among three methods: 753.80±5.79 mg TE/L (ABTS), 624.64±10.52 mg TE/L (DPPH), and 186.64±1.66 μmol TE/L (FRAP). In conclusion, UAEE showed promise in extracting carotenoids from lemon peel. Thus, by carotenoid extraction using green technology from waste lemon peels, with higher added value, richer in terms of phenolic composition and antioxidant properties, has been obtained.

“…In this latter scheme, a systematic framework is meticulously designed to exploit the inherent selectivity and permeability of membranes in separating, purifying, and concentrating these bioactive constituents from the complex matrices of vegetable extracts. A review article published by Saini et al [25] described the utilization of non-polar solvents, such as hexane, as underscored for the extraction of carotenoids owing to their hydrophobic nature. Additionally, the article explored the efficacy of polar solvents like ethanol and methanol in extracting phenolic compounds.…”

In new food formulations, carotenoids and phenolic compounds are likely to be the most sought after food ingredients according to their bioactivity, nutraceutical, nutritional value, and compatibility properties once incorporated into food formulations. Such solutes are naturally present in many plant-based sources, and some portions are directly consumed when enriching food products and formulations; however, some portions, which are contained in the parts of the plant sources not considered edible, including the leaves, peel, and seeds, among other by-products, are commonly wasted. Related to this, scientists have found a new window for obtaining these bioactive molecules, but their recovery remains a challenge. To some extent, the final purification and polishing requires highly selective performance to guarantee the desired properties and concentration. In this regard, membrane technologies, such as nanofiltration (NF), represent an alternative, owing to their highly selective properties when separating low-molecular-weight compounds. NF becomes immediately suitable when the pretreated extracts are subjected to further efficient concentration, fractionation, and polishing of phenolic fractions and carotenoids. The separation efficiency (usually higher than 97%) of NF technology is high according to the low pore size of NF membranes, but the low temperature in process separation also contributes to the separation of thermolabile compounds. Therefore, this paper reviews the ongoing cases of studies reporting the successful separation and polishing of phenolic fractions and carotenoids from distinct sources. In particular, we have focused our attention on the main interactions during the separation process and the drawbacks and advantages of using membranes for such a case study.
