Voedselbron van de toekomst Insecten eten: Onverteerbaar?

De Food and Agriculture Organisation of the United Nations FAO prijst insecten aan als ‘food of the future’. Tachtig procent van de wereldbevolking vindt dat al heel gewoon. De meeste mensen in ‘het Westen’ vinden het idee van insecten eten echter nog altijd onverteerbaar. Toch neemt de weerstand langzaam af. TNO doet alvast onderzoek naar de...

Purification and characterization of a beta-D-xylosidase and an endo-xylanase from wheat flour

Polysaccharide hydrolysing enzymes from wheat (Triticum aestivum) flour

Variation in the degree of d-xylose substitution in arabinoxylans extracted from a European wheat flour

Total water-extractable arabinoxylan from flour of the European bread making wheat cultivar Camp Remy was fractionated by ethanol precipitation. Both 1H-NMR spectroscopy and methylation analysis of the isolated arabinoxylan fractions showed wide variation in the degree of xylose substitution. More highly substituted arabinoxylan fractions were...

Evidence for the presence of arabinoxylan hydrolysing enzymes in European wheat flours

Water extracts of flour samples prepared from six sound European wheat varieties hydrolyse p-nitrophenyl-β-d-xylopyranoside and p-nitrophenyl-α-l-arabino-furanoside and, in addition, release soluble, dyed fragments from azurine crosslinked xylan. Incubation of water soluble wheat arabinoxylan with water extracts of flour results in the release...
