摘要

Coconut oil, extracted from mature coconut kernels, is a versatile natural product sourced from coconut palms. This study uniquely highlights how different farming practices influence the functional quality and antioxidant potential of coconut oil, offering valuable insights into health benefits and sustainable production choices. The method of farming, whether organic or inorganic, significantly impacts the quality and composition of the extracted oil. This study investigated the physicochemical and antioxidant features of coconut oils derived from both organic and inorganic cultivation practices. Five combinations of various organic and inorganic fertilizers were employed in the agricultural practice, namely the treatments, T1 and T2 utilized in-situ organic matter, green manure, and PGPR (plant growth-promoting rhizobacteria) consortia, with T2 additionally incorporating cow dung. T3 and T4 comprised all components of T1 along with recommended K2O using sulphate of potash, while T5 utilized conventional chemical fertilizers. The physicochemical properties and antioxidant potential of resultant oil samples were analyzed. The results indicated that T4 treatment produced oil samples of superior quality, making them the best choices for culinary and oral applications. The nutritionally important total phenolic content of T4 was found to be in the range of 0.0173 mg GAE/g. Treatment T4 also demonstrated superior antioxidant activity, as indicated by its higher DPPH radical scavenging capacity (39%) and FRAP value (0.96 mg Trolox equivalent /100 g), surpassing those of the other treatments.
