| Abstract: |
| Phytosterols are a class of natural active ingredients widely found in vegetable oils, nuts, and grains, possessing numerous physiological benefits. To provide a basis for developing functional foods based on the molecular characteristics of phytosterols, the types of phytosterols were summarized, and the physiological functions of different types of phytosterols and their applications in food were elaborated in detail. Based on the degree of methylation at the C-4 position, phytosterols are classified into three categories: 4-desmethylsterols, 4-monomethylsterols, and 4,4-dimethylsterols. 4-Desmethylsterols exhibit cholesterol-lowering, anticancer, and hormone-like functions, and the related mechanisms have been widely reported. 4,4-Dimethylsterols demonstrate unique activities in improving lipid metabolism, regulating endocannabinoid system and nervous system. The safety of phytosterols in food applications has been recognized by multiple countries and institutions worldwide, and they are primarily used in vegetable oils, dairy products, chocolate, and other foods. Future research should focus on elucidating the modification techniques and efficacy mechanisms of phytosterols, as well as developing phytosterol-enriched foods tailored to China′s population dietary structure, to fully leverage their nutritional and health benefits. |
