On the 8th day of storage, no significant differences were recorded for smell, visual appearance, texture and general acceptability when the control was compared with OEO or CITRAL. Only differences between oregano essential oil and citral were found by the judges. The samples with CITRAL were clearly preferred on day 8 of storage.
OEO and CITRAL resulted in a pleasant flavour, compatible with final products. This is a prerequisite for the use of essential oils in foods for antimicrobial purposes.
