Outline
Seed oils are an important source of dietary lipids for humans. Their processing technologies and quality evaluation techniques are directly related to nutritional value and food safety. This paper systematically reviewed the research progress in the extraction processes and quality control of seed oils in recent years. Firstly, the application status and key parameters of traditional oil extraction processes, including mechanical pressing and solvent extraction, were summarized, with a focus on their respective advantages and limitations regarding energy consumption, oil yield, and quality retention. Secondly, the latest progress in modern oil extraction technologies, such as supercritical fluid extraction, enzyme-assisted processes, microwave/ultrasound enhancement, low-temperature cold pressing and microbial fermentation, were emphasized with respect to their roles in enhancing extraction efficiency, preserving bioactive compounds and supporting sustainable production. Regarding quality control and evaluation, this paper summarized key parameters including physicochemical indicators (acid value, peroxide value, saponification value), sensory attributes (color and odor), fatty acid composition, phytosterol and polyphenol contents, as well as a multidimensional evaluation system for safety and oxidative stability. Research indicated that process optimization and multi-parameter collaborative evaluation were central to ensuring the nutritional quality and safety of seed oils. The study further highlighted the need for integrating green processing with digital intelligent detection to drive the sustainable production of high-quality seed oils.
