Listing description
Tomato seed oil is a vegetable oil
extracted from the seeds of tomatoes.The possibility of extracting oil from tomato seeds was studied in the USA in 1914. Seeds were obtained from a variety of locations and pressed to produce oil. This was refined using an alkali and then clarified with fuller's earth. The resulting oil was pale yellow and considered suitable for dressing salads.
Detailed description
The seeds
have been given renewed attention as there is pressure to utilise the waste
products of tomato processing, in which seeds are the largest component. In
Greece, over a million tons of tomatoes are processed each year and the
resulting quantity of seeds might be used to produce up to 2000 tons of oil.
The oil from Greek seeds has been extracted by using ether as a solvent. When
analysed, it was found to contain a high proportion of unsaturated fatty acids,
especially linoleic
acid.
