Volatile Profiles in Cold-Pressed Peel Oil from Korean and Japanese Shiranui (Citrus unshiuMarcov. ×C. sinensisOsbeck ×C. reticulataBlanco)

Abstract

A comparison of the volatile profiles between Korean and Japanese Shiranui cold-pressed peel oil was performed by GC and GC-MS. Limonene was the most abundant in the Japanese (91.8%) and Korean (86.4%) oil. Alcohols accounted for 1.8% in the Korean oil, and 0.2% in the Japanese oil, in which the respective linalool levels were 1.2% and 0.1%. The level of aldehydes was also higher in the Korean oil (1.6%) than in the Japanese oil (0.7%).
