“…These beneficial effects of H 2 might be related to its reducing and antioxidant properties, small size, and high diffusion rate in the atmosphere and tissues (Alwazeer, 2020;Alwazeer et al, 2021). In recently published studies, our team showed that the incorporation of hydrogen gas into both methanol or hexane improved the extraction of antioxidants and phenolics from vegetable oils (Ceylan et al, 2023), by-products (Alwazeer et al, 2023b,c) and agri-food wastes (Alwazeer and Elnasanelkasi, 2023;Alwazeer et al, 2023a).…”

The impact of hydrogen infusion into solvents on the extraction of phytochemicals was evaluated. Pure (water, ethanol, methanol) and hydrogen-rich solvents at temperatures (25°C and 35°C) were used for extracting phenolics, flavonoids, anthocyanins, and antioxidants from lemon peel. Incorporating hydrogen into all solvents increased the extraction of all phytochemicals. The hydrogen incorporation into solvents led to the highest increase in phenolics and flavonoid contents shown for hydrogen-rich methanol (HRM) followed by hydrogen-rich ethanol (HRE) at both 25°C and 35°C. The highest antioxidant extraction was shown for HRM. The hydrogen incorporation showed the highest phytochemical extraction in methanol and at 35°C. The increase in temperature increased the extraction efficiency, but less efficiently than the hydrogen incorporation. The HPLC phenolic profile confirmed the positive effect of both temperature and hydrogen incorporation on the extraction of flavonoids and non-flavonoids. The improvement of the phytochemical extraction by the proposed method can bring many economic and ecological advantages.

“…This washing process was performed three times. 51 Each washing step led to an improvement in the color of COPO, that is, it became purer, yielding a greener and yellower product (lower a* value and higher b* value). This result may have been obtained by removing impurities from the olive oil samples and making the pigments (chlorophylls and carotenoids) purer.…”

IntroductionPhytochemicals are used in many products, including foods, beverages, pharmaceuticals, and cosmetics. The extraction of phytochemicals is considered one of the best solutions to valorize these underestimated materials. Many methods have been developed to efficiently extract phytochemicals at high quality, high purity, and low costs without harming the environment. Recently, molecular hydrogen (H2) has shown its ability to improve the extraction of phytochemicals from plant materials. Due to its unique physicochemical and biological properties, H2 showed an efficient ability to extract phenolics and antioxidants at high yields with cost‐effective potential. Without sophisticated equipment and high energy and solvent consumption, the hydrogen extraction method is a green and applicable alternative for the extraction of phytochemicals.ObjectivesThis review aims to provide the latest knowledge and results concerning the studies on using hydrogen‐rich solvents to extract phytochemicals from different agri‐food wastes, by‐products, and other plant materials.Materials and MethodsRecent literature relating to extracting phytochemicals by the hydrogen‐rich solvent method and its potential mechanisms is summarized to provide a basic understanding of how hydrogen can improve the extraction of phytochemicals.ResultsThis review describes, for the first time, the practical procedure of how researchers and laboratories can apply the hydrogen extraction method under safe conditions at a low‐budget scale. The review provides some examples of the hydrogen extraction method and the mechanisms and rationale behind its effectiveness.ConclusionsIt can be concluded that the hydrogen‐rich solvent method is a green and cost‐effective method for extracting phytochemicals from different plant materials.
