Identification of the Botanical Origin of Commercial Pine Nuts Responsible for Dysgeusia by Gas-Liquid Chromatography Analysis of Fatty Acid Profile

Table 2

Fatty acid profile of pine nuts samples containing only one type of pine nuts. Diagnostic index (DI) value: DI = [(5, 9–18 : 2 + 5, 9, 12–18 : 3 + 5,11,14–20 : 3) / (18 : 1 n-9 and n-7 + 18 : 2 n-6 + 20 : 2 n-6)] × 10. Results of duplicate analysis expressed as g per 100 g of fatty acids.
