Effects of Ice Cream Produced with Lemon, Mandarin, and Orange Peel Essential Oils on Some Physicochemical, Microbiological and Sensorial Properties

In this study, some physicochemical, microbiological and sensorial properties of ice cream produced with essential oils obtained from lemon (L), mandarin (M), and orange (P) peels at different ratios (0.1%, 0.3%, and 0.5%) were investigated. The highest amount of dry matter was determined in sample P3 which contains 0.5% lemon peel essential oil as 39.36%. The pH and % acidity values of the samples were found to vary between 6.36-6.45 and 0.22-0.27, respectively. At the end of the study, the lowest total aerobic mesophilic bacteria (3.80 log CFU/g), psychrophilic bacteria (4.01 log CFU/g), yeast and mold (3.71 log CFU/g) and Pseudomonas spp. (2.04 log CFU/g) counts were determined in ice cream sample P3. The total coliform group bacteria, Salmonella spp., Staphylococcus aureus, Escherichia coli, and Listeria monocytogenes were not detected in any of the ice cream samples. As a result of the sensory evaluation, it was determined that the most admired sample was P3 and the least preferred sample was the control sample.
