Abstract The invention relates to a method and an apparatus for an enzymatic hydrolysis in which plant based raw material is hydrolysed by means of enzymes. The plant based raw material (1) is fed to the first enzymatic hydrolysis stage (2), the plant based raw material (1) is hydrolysed in at least two enzymatic hydrolysis stages (2,4), a liquid fraction (5a,5b) comprising carbohydrates is separated from a solid fraction (6a,6b) in a solid-liquid separation stage (7a,7b) after each enzymatic hydrolysis stage (2,4), and the solid fraction (6a) is supplied to the next enzymatic hydrolysis stage (4) in which the solid fraction is treated, and the solid fraction (6b) is recovered after the last solidliquid separation stage (7b). Further, the invention relates to the liquid fraction and the solid fraction and their use. Keksintö koskee menetelmää ja laitteistoa entsymaattiseen hydrolyysiin, jossa kasvipohjainen raaka-aine hydrolysoidaan entsyymien avulla. Kasvipohjainen raakaaine (1) syötetään ensimmäiseen entsymaattiseen hydrolyysivaiheeseen (2), kasvipohjainen raaka-aine (1) hydrolysoidaan vähintään kahdessa entsymaattisessa hydrolyysivaiheessa (2,4), nestefraktio (5a,5b), joka käsittää hiilihydraatteja, erotetaan kiintoainefraktiosta (6a,6b) kiintoaine-neste-erotusvaiheessa (7a,7b) kunkin entsymaattisen hydrolyysivaiheen (2,4) jälkeen, ja kiintoainefraktio (6a) johdetaan seuraavaan entsymaattiseen hydrolyysivaiheeseen (4), jossa kiintoainefraktio käsitellään, ja kiintoainefraktio (6b) talteenotetaan viimeisen kiintoaine-neste-erotusvaiheen (7b) jälkeen. Lisäksi keksintö koskee nestefraktiota ja kiintoainefraktiota ja niiden käyttöä.
