Preparation of high fructose syrup from the new zealand cabbage tree cordyline australis

, : Preparation of high fructose syrup from the new zealand cabbage tree cordyline australis. New Zealand Journal of Technology 1(1): 27-32

The water extracts of the stem and root of the New Zealand cabbage tree, Cordyline australis, contain a glucofructofuranan polysaccharide. A cold water extraction process, followed by hydrolysis of acid-labile .beta.-fructofuranosyl linkages in the polysaccharide using 0.015 M phosphoric acid and the neutralization with calcium hydroxide, permits the preparation of high-fructose syrups with a fructose content comparable to those used in the food processing industry. An HPLC method which is suitable for the analysis of both the water extracts of C. australis, and the high-fructose syrups produced from them, is described. Other possible end-uses for C. australis, including liquid fuel production, are referred to.
