The oleogels were produced with beeswax (BEW), carnauba wax (CRW), candelilla wax (CLW), and their ternary blend in equal proportions.

The samples with CLW and CRW formed smaller ice crystals, while the ternary blend had a low overrun. The lipid profile of the ice creams produced with oleogels showed lower amounts of saturated fatty acids than samples produced with milk fat did, showing that waxes oleogels are a technological and healthy viable alternative to replace milk fat in ice cream.

The entire procedure was systematically monitored to determine the optimum conditions for biodiesel production. The biodiesel yield depends on the type of alcohol used, the molar ratio of alcohol to oil, the type and concentration of catalyst, reaction time, and the water content of the oils and fats. The viscosity of kapok methyl ester (KME) was reduced by approximately 85% compared to raw kapok seed oil. The flash and fire points of KME are higher than those of conventional diesel fuel. Additionally, the calorific value, cetane number, and other fuel properties of KME are comparable to those of diesel. The oxidative stability of KME was found to be 12.3 h, which is higher than the specified values in ASTM D6751. This indicates greater resistance to oxidation, improved storage stability, longer shelf life, and a lower risk of deposit formation. These results validate kapok seed oil as a sustainable, nonedible, and affordable feedstock for the generation of biodiesel. Further research on engine performance, emission profiles, and long-term stability is suggested in order to confirm KME's viability for practical energy applications.
