A sequential injection analysis (SIA) system for the spectrophotometric determination of L (+)-
lactate using lactate oxidase/peroxidase was developed and applied to wine analysis. It …

A flow-injection system for the enzymatic determination of L (+) lactic acid and L (−) malic
acid in wines with spectrophotometric detection is described. The samples are dialysed in …

The simultaneous determination of L‐malate and L‐lactate, by enzyme‐supported flow
injection analysis (FIA), was developed using two enzyme reactors in parallel and a single …

A simultaneous flow injection method for the determination of malic and lactic acids in wines
based on the coupling of dialysis-enzymic derivatisation with either photometric or …

A method for determination of l-malate in wine is described. Malate dehydrogenase and
oxaloacetate decarboxylase were immobilized on poly (vinyl alcohol) beads and …

The enzymatic determination of L (-) malic and L (+) lactic acids in several types of wines by
flow injection analysis (FIA) with spectrophotometric detection is described. This flow …

In the present work a sequential injection system for the enzymatic determination of l (−)
malic acid in wines is described. The determination was based on the detection of NADH …

A flow injection system for the enzymatic determination of L-malate is described. It is
adapted for the analysis of wines and fruit juices by in-line sample dilution. Malate …

An automated method for determining laccase activity in musts and wines is here presented.
The method is based on the Flow Injection technique using the mode of stop-flow at the …

A simultaneous determination of two organic acid species in wine by a flow injection
analysis method using enzyme-immobilized open tubular reactors is described. The design …
