The inhibitory effect of Sichuan pepper seed essential oil on Bacillus licheniformis: Action mechanism analysis based on metabolomics and application in milk

Puntos clave

• Sichuan pepper seed essential oil significantly inhibits bacillus licheniformis growth in milk.
• The study shows a notable reduction in bacterial activity by over 70% using specific concentrations of essential oil.
• Analysis based on metabolomics reveals the mechanisms behind the inhibitory effect on bacterial metabolism.
• These findings suggest that essential oil could serve as a natural alternative for food preservation, especially in dairy.
