The results showed that addition of propylene glycol to TVO/AA or PAT80/water MEs gave dilutable systems with particles ~59 nm in diameter. Plain TVO showed the highest antimicrobial activity against E. coli, S. aureus, and S. typhi in in vitro antimicrobial tests, followed closely by AA/PA-MEs. The antimicrobial activity of AA/PA-MEs used as a washing solution on cucumber and strawberry samples was remarkably greater than those of free TVO, TVO nanoemulsions, and chlorhexidine solutions against E. coli and S. aureus. The sensory properties of the samples were not changed by the use of AA/PA-MEs at 0.05 or 0.1% TVO. The results introduce dilutable TVOAA/PA-MEs for incorporation of TVO in aqueous systems for use as a fruit/vegetable disinfecting agent.The impact of fermentation assisted by four different lactic acid bacteria (LAB) on polyphenols, carotenoids, organic acids, and antioxidant capacity of orange-juice milk based beverages was evaluated. Lactobacillus brevis POM, and Lactobacillus plantarum (TR-7, TR-71, TR-14) were used to promote the fermentation of the beverages for 72 h at 37 °C. The bacteria population increased with the elapse of fermentation period, except for beverages inoculated with L. plantarum TR-7. After fermentation period, total polyphenols, total carotenoids and total antioxidant capacity were increased compared to the control ones (non-fermented). Two phenolic acids (DL-3-phenylactic acid and 3-4-dihydroxyhydrocinnamic acid) and lactic acid were identified after 72 h fermentation. Overall, it is possible to conclude that orange-juice milk beverages are a good medium for the growth of L. brevis POM, and L. plantarum (TR-71, TR-14), observing higher antioxidant properties in the fermented beverages compared t
