Summary

 Plant essential oils (EOs) have several technological properties such as antimicrobial, antioxidant, enzyme inhibitors, etc., which are then highly valued in the food sector as a sustainable conservation alternative to controversial chemical additives. Active packaging with EOs is a technique with great potential to extend the shelf life of fruit and vegetables. For it, we studied the application of active paper (kraft) sheets (including β-cyclodextrin inclusion  complexes with a thymol:eugenol mix (50:50)) to preserve cherry tomatoes (also known as grape  tomatoes) for up to 14 days at 10 ºC. The tomato quality was assayed through physicochemical (pH), colour and microbial analyses. The microbial growth of psychrophilic was highly controlled, with ≈1 log unit lower counts compared to control after 14 days of refrigerated storage, in tomatoes when the active sheets were used. Furthermore, active sheets did not affect (p>0.05) the physicochemical quality (pH) or colour of tomatoes. Conclusively, EOs active sheets packaging controlled microbial growth during refrigerated storage of tomatoes.
