Units are log CFU/g. Results indicate mean values ± S.D. of four plate counts (carried out in triplicate for two independent productions). Data within a column followed by the same letter are not significantly different according to Tukey’s test. Abbreviations: CTR, uncoated fruit slices, AVG, fruit slices coated with 40% v/w of Aloe vera gel only, HPMC, fruit slices coated with 40% v/w of Aloe vera gel + 0.1% v/w of hydroxypropyl methylcellulose, LEO, fruit slices coated with 40% v/w of Aloe vera gel + 0.1% v/w of lemon essential oil, TMM, total mesophilic microorganisms, TPM, total psychrotrophic microorganisms and NS, not significant (p-value ≥ 0.05).
