Fermentation of dietary fibre in the intestinal tract of rats - a comparison of flours with different extraction rates from six cereals

The fermentation of dietary fibre in wheat, rye, barley, sorghum, rice and maize was investigated in balance experiments with rats. Two different extraction rates, 100% and approximately 65%, were investigated for each cereal grain. In the case of maize, whole maize, and dehulled maize that had been ground and sieved so that it contained mainly endosperm, were investigated. Except for sorghum, die

Binding of 14C-labeled food mutagens (IQ, MeIQ, MeIQx) by dietary fiber in vitro.

Binding of three mutagens, known to occur in fried or broiled foods, by thirteen different types of dietary fiber was investigated in vitro. Nonspecific binding by other food polymers was minimized by using protease and amylase treatment. Water‐insoluble fiber components were responsible for most of the binding capacity. Generally, a slightly larger proportion of 2‐amino‐3,4‐dimethylimidazo [4,5‐f

On the digestibility of starch in wheat bread - studies in vitro and in vivo

The digestibility of starch in white wheat bread was studied. Raw wheat starch and raw wheat flour were used as reference materials. The extent of digestion and absorption in vivo was evaluated through balance experiments in rats given test diets with and without addition of the antibiotic, Nebacitin, to reduce the fermentation in the hind-gut. As judged from a high faecal recovery of dietary fibr

Vegetable, fruit and potato fibres

As much as one-third of the dietary fibre intake in a normal Western diet originates from fruits and vegetables. Nutritional effects of dietary fibre can to a great extent be related to the physicochemical properties of the fibre, such as composition, solubility, viscosity, water-holding capacity and molecular weight. In fruits and vegetables the structure of the cell wall matrix (tertiary structuAs much as one-third of the dietary fibre intake in a normal Western diet originates from fruits and vegetables.
