Extract

In vitromethods for laboratory estimation of food degradation are important tools for nutritionists.These methods either measure substrate disappearance by quantifying incubation residues or record fermentation products such as microbial biomass, short-chain fatty acids (SCFA) or gas volume (Blümmel et al., 1997a). Recently, the surge of interest in the efficient utilization of roughage diets has caused an increase in the use of gas methods because of the possibility of estimating the extent and rate of degradation in one sample by time series measurements of the accumulating gas volume. We combined gas measurements with residue determinations (truly degraded substrate) or microbial mass determination after fermentation to study the effects of natural plant products, in particular tannins and saponins, on the availability and partitioning of nutrients.
