Mar 01, 2008· The selection of vegetable oils and industrial fats for which α-T values and plant sterol contents are provided by the Finnish food composition database no longer reflects the current market situation. In order to enable update of the database, the tocopherol, tocotrienol and plant sterol contents of composite samples were determined using
The tocopherol and tocotrienol (i.e. tocol) and plant sterol contents of 14 vegetable and 9 industrial fats and oils available on the Finnish market in 2005 were determined using NP-HPLC with fluorescence detection (tocols) and GC-FID (plant sterols). Best sources of α-tocopherol were wheat germ (192 mg/100 g) and sunflower oil (59 mg/100 g

The tocopherol and tocotrienol (i.e. tocol) and plant sterol contents of 14 vegetable and 9 industrial fats and oils available on the Finnish market in 2005 were determined using NP-HPLC with fluorescence detection (tocols) and GC-FID (plant sterols). Best sources of a-tocopherol were wheat germ (192mg/100g) and sunflower oil (59mg/100g).
The four species were comparable in tocopherol composition, with γ‐tocopherol representing 96–99% of the total tocopherols.

Investigation showed that α- and ɣ- tocopherol were the major homologues in vegetable oils and fats. The highest content of total tocopherols was found in sunflower oil (788.1 μg/g) and the main vitamer was α-tocopherol. The lowest tocopherols level and simultaneously the highest tocotrienols content was found in black caraway oil.

The fatty acid, tocopherol and sterol contents of the oils of several poppy seeds were investigated. The main fatty acids in poppy seed oils were linoleic (687.6-739.2 g kg-1), oleic (141.3-192.8 g kg-1) and palmitic (76.8-92.8 g kg-1). The oils contained an appreciable amount of -tocopherol (195.37-280.85 mg kg-1), with a mean value of 261.31 mg kg-1 and α-tocopherol (21.99-45.83 mg kg-1

Vegetable oils can be modified to improve their stability in the frying process. This modification involves processes such as fractionation, hydrogenation and genetic modification of the fatty acid composition of plant seeds (Rossell, 2001b).
