## Abstract The normalβacid method for the estimation of fibre in roughages by single acid digestion has been reβexamined. Increasing the time of digestion from 1 to 3 h. gives a marked improvement in the correlation with digestibility. Changes in technique are also introduced which make the method
We describe a modified colorimetric method that quantitates inorganic phosphate linearly up to 60 nmol, with high stability of the developed color and with a low interference by ATP concentration (up to 30 mM). This method is very suitable for use in ATPase enzymatic assays, especially with enzymes
## Abstract The D/L ratio of aspartic acid enantiomers in proteins of low turnover is generally accepted as a reliable procedure for age determination. In our study, twelve samples of eyetooth dentin were analyzed for age determination. The pure insoluble collagen isolated from eyetooth dentin was
Several reagents and experimental conditions were tested to optimize the yield of the derivatization procedure for determining carboxylic acids in wines. Two techniques were applied for optimization: a modified sequential simplex method and a simultaneous modelling method. The results obtained were
