Description

field of invention

[0001] The present invention relates to a plant extract containing at least proteins, polysaccharides, lipid compounds and minerals, said extract being especially rich in carotenoids and other antioxidants. The present invention also relates to a method for preparing such an extract without using any solvents, nor processing aids or additives. Background of the invention

[0002] Plant pigments are usually separated with organic solvents. For example, carotenoids can be extracted with hydrocarbon solvents such as chloroform, hexane, and other organic solvents.

[0003] G.Salder et al. ("Journal of Food Science" 1460-1461,55,5,1990) described the rapid extraction from reconstituted tomato paste and pink grapefruit homogenate with hexane-ethanol-acetone (50:75:25) A method for lycopene and beta-carotene, which yielded a pure extract with high recovery of these carotenoids. A major concern is that the use of organic solvents can be detrimental to the furth...
