“…It should be noted that, the concentration of β‐sitosterol in the refined phytosterols was significantly increased compare to that in crude ones. This is attributed to the high solubility of β‐sitosterol in acetone and ethanol (Evtyugin et al, 2023). It has been shown that β‐sitosterol has a much greater solubility in these organic solvents than stigmasterol during the purification process using the solvent crystallization method (Xu et al, 2005).…”

This study aimed to improve the comprehensive utilization value of rice bran by investigating catalysts for the methyl esterification reaction of rice bran oil deodorized distillates and preparing phytosterol nanoparticles for addition to yogurt. Fe2(SO4)3 was found to be an effective catalyst, achieving a methyl esterification rate of 98.07 ± 0.23% under optimal conditions. Then, phytosterol nanoparticles were prepared and added to yogurt, resulting in stable addition with the pH decreased from 4.23 ± 0.01 to 4.02 ± 0.01 and the titratable acidity increased from 106.48 ± 0.85 °T to 117.07 ± 0.82 °T during storage. The addition of phytosterol nanoparticles increased the apparent viscosity from 0.68 ± 0.01 Pa s to 0.72 ± 0.02 Pa s and the G* from 80.01 ± 5.50 Pa to 91.80 ± 1.99 Pa, resulting in thicker and more elastic texture. Phytosterol nanoparticle improves the dispersion and stability of phytosterols in yogurt, thus making it stable to be added to yogurt. Fe2(SO4)3 is a suitable catalyst for the methyl esterification reaction of rice bran oil deodorized distillates, and the addition of rice bran phytosterol nanoparticles to yogurt can enhance its texture and nutritional value, offering a promising strategy for producing high value‐added products from rice bran.

“…The side streams from hardwood sulphite pulping may represent an underutilized potential source of PS similar to those already explored from softwood kraft pulping, even though the recovery may be challenging [ 369 ]. Nonetheless, a promising method was reported for recovering β-sitosterol (BS) (>90% purity) from bleaching effluent of dissolving Eucalyptus pulp production using magnesium (Mg 2+ ) - based acid sulphite pulping [ 370 ].…”

Plant sterols (PS) are cholesterol-like terpenoids widely spread in the kingdom Plantae. Being the target of extensive research for more than a century, PS have topped with evidence of having beneficial effects in healthy subjects and applications in food, cosmetic and pharmaceutical industries. However, many gaps in several fields of PS’s research still hinder their widespread practical applications. In fact, many of the mechanisms associated with PS supplementation and their health benefits are still not fully elucidated. Furthermore, compared to cholesterol data, many complex PS chemical structures still need to be fully characterized, especially in oxidized PS. On the other hand, PS molecules have also been the focus of structural modifications for applications in diverse areas, including not only the above-mentioned but also in e.g., drug delivery systems or alternative matrixes for functional foods and fats. All the identified drawbacks are also superimposed by the need of new PS sources and technologies for their isolation and purification, taking into account increased environmental and sustainability concerns. Accordingly, current and future trends in PS research warrant discussion.
