Cremer A1 Roger Boulton YR 1981 UL http://www.ajevonline.org/content/32/1/18.abstract AB A design for an immobilized enzyme reactor suitable for the hydrolysis of gelatin in a potassium bitartrate buffer at pH 3.5 was developed. The influence of protein concentration, mass transfer and kinetic control on the design are considered with regard to the possible hydrolysis of grape proteins in musts.
