Exploring the Application of Waxes and Their Mixtures Oleogels in Ice Cream
Journal of the American Oil Chemists' Society, EarlyView.ABSTRACT The objective of this work was to produce ice cream using waxes oleogels, aiming to improve its nutritional value while maintaining its physical‐chemistry characteristics. Five ice cream formulations were manufactured using (1) milk fat, (2) canola oil, and (3–5) canola oil‐oleogels. The oleogels were produced with beeswax (BEW), carnauba wax (
