This article systematically reviews the\u00a0principles, equipment, key influencing factors, application cases, and comparisons with other extraction technologies, while also analyzing its safety, sustainability, and industrial potential. LPG (primarily composed of propane and butane) enables efficient extraction under mild pressure (0.5\u20133.5\u00a0MPa) and low temperature (20\u201340\u00b0C) due to its\u00a0low polarity, low boiling point, and high diffusivity, effectively preserving thermolabile compounds. In contrast to\u00a0supercritical CO\n                    <jats:sub>2<\/jats:sub>\n                    extraction, LPG reduces\u00a0equipment costs by 30\u201350% and energy consumption by 40%.

Although LPG has limitations in extracting polar compounds, its applicability can be expanded by adding polarity modifiers (e.g., ethanol) or optimizing process parameters (e.g., temperature and pressure). Future research should focus on developing LPG polarity modification techniques, improving safety measures, integrating with other green technologies, and overcoming industrialization barriers to facilitate large\u2010scale applications in food, pharmaceutical, and cosmetic industries.\n
