Abstract
In recent years, there has been a noticeable surge in exploring alternative methods for the conservation of dairy products, favoring the use of essential oils over synthetic preservatives. The trend toward natural solutions reflects a broader demand for healthier and more sustainable food preservation choices. The aim of this study is to monitor changes in the physico-chemical, sensory, and microbiological characteristics of a milk-derived product eventually induced by the incorporation of lemon essential oil (LEO) of leaf at different concentrations (0.125%, 0.5%, and 1.25%). LEO incorporation showed an effect (P<0.05) on pH, dry matter, titratable acidity, ash, aerobic mesophilic flora, and lactic acid bacteria of the control and aromatized cheeses. In addition, no pathogenic flora growth was observed in aromatized cheese. Thus, LEO is a promoting agent in the preservation and aromatization of fresh cheese and can be applied at 0.5%.
