Abstract
|
|
|
|
Acid- and enzymatic hydrolysis properties of two fructans (inulin and levan) and their oligofructoses has been investigated. At pH 1, the initial fructose release rate differs and is rapidly hydrolyzed in the order of levan oligosaccharide and inulin oligosaccharide, levan, inulin. At pH 4.5, 7 and 14, no or little amount of fructose are found from four samples. At the presence of inulinase in the reaction mixture, the fructose is rapidly produced from all samples, whilst invertase treatments show low activities. The results allow the estimation of the fructose release rate in many foodstuff processing conditions.
