Fibre composition of the following 13 apple cultivars was studied: 'Cortland', 'Empire', 'Fuji', 'Golden Delicious', 'Gala', 'Granny Smith', 'Jonagold', 'Mutsu', 'McIntosh', 'Delicious', 'Rome', 'Stayman' and 'York'. Fruit samples from each of these cultivars were analysed for non-starch cell wall materials (NSCWM) and non-starch polysaccharides (NSP). NSCWM was further fractionated into soluble and insoluble fibre fractions. Both NSCWM and NSP content were found to be significantly influenced by cultivar. NSCWM content ranged from 19.1 g kg-1 apple flesh in 'Fuji' to 36.2 g kg-1 in 'York'. Mean (+/- SD) NSCWM content of all the cultivars was 23.1 +/- 4.5 g kg-1. NSP content of apple flesh ranged from 13.8 g kg-1 in 'McIntosh' to 28.7 g kg-1 in 'York' with the overall mean for all cultivars being 17.9 +/- 4.2 g kg-1. Relative amount of monosaccharides found in the hydrolysates of apple fibre also varied among cultivars. The greatest difference was observed in galactose content.
