Exploring Phylogenetic Relationships between Hundreds of Plant Fatty Acids Synthesized by Thousands of Plants. more details ...
Abstract Tabulated data are presented on the variations in fatty acid composition, sterols, tocopherols, spectrophotometric indices and peroxide values during 3 yr storage of (i) sweet and (ii) bitter almond oils at 4° C or ambient temp. No differences in fatty acid composition were observed between (i) and (ii) but the sterol and tocopherol composition was different: (i) contained only alpha-tocopherol (45.8 mg/100 g), (ii) also contained gamma-tocopherol (34.5 mg alpha- + 11.3 mg gamma-tocopherol/100 g). During storage, the spectrophotometric indices and peroxide values rose while tocopherol contents fell (to 24.5 and 12.1 mg/100 g resp. in (i) and (ii) after 2 yr at 4° C, to 0 after 3 yr at 4° C or 2 yr at ambient temp.). Peroxide value in (i) rose from 9.6 to 21.3 after 1 yr, 29.6 after 2 yr and 129.5 after 3 yr at 4° C, with similar rises in (ii) and in spectrophotometric indices and much faster oxidative changes at ambient temp.
