Abstract: Methods for providing transgenic plants and parts hereof that, relative to the wild type state, is modified in a complex cell wall polysaccharide structure including pectins and hemicelluloses, the modification being in the overall glycosidic linkage pattern or the monosaccharide profile, comprising transforming a plant cell with a nucleotide sequence that causes an altered production of a complex cell wall polysaccharide-modifying enzyme such as endo-rhamnogalacturonan hydrolase, an endo-rhamnogalacturonan lyase, an endo-galactanase, an endo-arabinanase, an arabinofuranosidase, a galactosidase such as a beta-galactosidase, a xylosidase and an exo-galacturosidase. The modification can occur in vivo or post harvest, in which latter case the modifying enzyme is separated in the growing plant from its substrate, e.g. by targeting the enzyme to the Golgi, the endoplasmic reticulum or a vacuole, or is in a form that is inactive in the plant.

Abstract: An enzyme preparation composition comprising a mixture of enzymes comprising an enzyme with homogalacturonan activity, more specifically pectin lyase, and an enzyme with endoglucanase activity, wherein the enzymes are in relative proportions to produce cloud volume from fruit or vegetable material. The preparation is such that enzymes which reduce the cloud volume by more than 5% are excluded, and wherein the endoglucanase has both CMCase activity and xyloglucanase activity in a ratio of at least 0.7.
