Exploration of the chemical composition, structural properties and efficient extraction method of Fructus cinnamomi kernel oil: An underexplored natural high lauric acid lipid

In the present study, the extraction methods, chemical composition, thermal properties, and structural characteristics of Fructus Cinnamomi Kernel Oil (FCKO) were investigated. For seed oil extraction, LCPE resulted in a higher oil yield of 99.2%, which was an increase of 28% and 17.03% compared to the MP and SE methods, respectively. Lauric acid was the primary fatty acid in the FCKO , with contents ranging from 76.67% to 82.71% (w/w). FCKO contains 53.6 mg/kg α-tocopherol, 211.0 mg/kg β-tocopherol, 38.5 mg/kg δ-tocopherol, and 84.16 mg/kg squalene. Additionally, FCKO remained stable up to 276.13 °C with negligible degradation. The melting range of FCKO was from 27.66 °C to 52.87 °C. FCKO has a high unique value and broad development prospects. This research provides prospects for the comprehensive development and utilization of FCKO .
