Perilla (Perilla frutescens L.) is an annual herbaceous plant whose seed oil is rich in unsaturated fatty acids such as alpha-linolenic acid (ALA). This oil exhibits various health benefits, including antioxidant, anti-inflammatory, lipid-lowering, hypoglycemic, neuroprotective and immunomodulatory activities. In addition, incorporating perilla oil into a diet can effectively increase the abundance of beneficial bacteria in the gut microbiota. However, perilla oil is prone to oxidation, which reduces its nutritional value and lowers its bioavailability. To address these issues, encapsulation technologies such as emulsions, oleogels, liposomes and microcapsules have been employed, showing promising results. Nonetheless, further research is needed to fully elucidate the underlying mechanisms of perilla seed oil's health effects, validate its benefits through large-scale human clinical trials and optimize encapsulation techniques. Future investigations should also explore the synergistic effects of combining perilla seed oil with other functional components and its role in modulating gut microbiota to achieve comprehensive health benefits.
