Preparation of Inulin from Dahlia Tubers

Preparation of Inulin from Chicory Roots

Inulin has immense applications in health and nutrition as well as in food industries. Inulin is isolated from chicory roots by differential precipitation with ethanol (0-20, 20-40 and 40-60 per cent) from the aqueous extract of sun-dried roots, by melting the frozen chicory root extract and by removing the oligo-fructosachharides from chicory roots with 20 per cent ethanol. Different inulin pr...

Production of inulinase from Kluyveromyces marxianus using dahlia tuber extract

Various carbon sources were evaluated for production of inulinase by yeast, Kluyveromyces marxianus MTCC 3995. Highest inulinase activity was observed with Dahlia extract (25.3 nkat mL(-1)) as carbon source. The enzyme activity was 1.4 folds higher than that observed in media containing pure chicory inulin (17.8 nkat mL(-1)). The yeast showed good growth on a simple medium containing dahlia ext...

The Dahlia: An Early History

In 1934 Marshall Howe, of the New York Botanical Garden, compiled a list of Dahlia cultivars containing more than 14,000 names. This number represents an astonishing average of over 100 newly named cultivars during each of the 143 years since 1791, when dahlias were first brought into cultivation in the gardens of Spain following their arrival from Mexico. Today dahlias are among the most famil...

(FOS) from inulin and applications

Inulin is a labile polyfructose polymer found in many sources as chicory, artichoke and dahlia roots. It ́s derived FOS (Fructo-OligoSaccharides) are produced using endo-inulinases or alternatively with less expensive and safe catalysts such as phosphoric and citric acids with good yields. Inulin and FOS deserve an important role against some diseases as colon cancer because can be selectively f...
