METHOD FOR CONCENTRATING AND STABILISING CAROTENOIDS FROM VEGETABLES OR FRUITS

摘要

The invention concerns a method for concentrating and stabilising carotene from vegetables or fruits, whereby in particular the fruits and vegetables are ground. The invention is characterised in that it consists in: blanching the resulting ground material, carrying out a second grinding process, acidifying the resulting second ground material, subjecting it to enzymatic liquefaction, concentrating it by tangential microfiltration, carrying a diafiltration thereof with 1 or 2 volumes of water, heat processing by heating, freezing it followed by thawing and producing concentration by centrifuging. The invention is useful for stabilising concentration.
