Comparative Study of Plant‐Based Antioxidants on the Stability of Soybean and Beef Tallow Biodiesels
Energy Science &Engineering, Volume 13, Issue 4, Page 1706-1719, April 2025.ABSTRACT Biodiesel is a renewable alternative fuel, but its oxidative instability reduces quality and performance over time. This study explicitly aimed to investigate the efficacy of natural antioxidants—acerola, soursop, mango, and pitanga leaves—and compare their performance to the synthetic antioxidant butylated hydroxytoluene (BHT) in enhancing ...
