Fortified beeswax oleogels: effect of β-carotene on the gel structure and oxidative stability

Abstract

) values for all concentrations due to the stronger oleogel network. X-ray diffraction measurements provide useful information on the crystal polymorphism type and arrangement of the internal lamellar phases of the crystals. Oil binding capacity is also affected by the incorporation of β-carotene into the oleogel and proven to be higher for the complex-beeswax oleogels, which enhances the ability of the oleogels to retain an oil phase within their crystalline network. The oxidative profiles of the complex-beeswax oleogels were studied during storage, and beeswax at the concentrations of 4, 6, and 8% revealed higher oxidative stability than that at the concentration of 2%. In this study, the possibility of tailoring the properties of oleogels is demonstrated considering the foreseen applications of oleogels in food products, such as in texturizers, as well their capacity to deliver bioactives and thus add value to food products.
