Effect of sowing date on the performance of root chicory

European Journal of Agronomy, 2001
Root chicory is a potential alternative sugar crop which accumulates a high amount of linear fructose polymers (fructan) in its roots. Lengthening the growing season by early sowing may increase root chicory yield potential, and thus increase its competitiveness with traditional sugar crops.

Effect of 2,4-dichlorophenoxyacetic acid on invertases in chicory root

Phytochemistry, 1979
Abstract The invertase present in roots of chicory (Cichoriun intybus) has a pH optimum of 7.5 and a MW of ca 260 000. It requires relatively high ionic strength to remove it from DEAE cellulose. Treatment of chicory root tissue with 2,4-dichlorophenoxyacetic acid gives rise to a highly active invertase with pH optimum of 5.6 and MW of ca 61 000.

Acids in chicory roots and malt

Zeitschrift f�r Lebensmittel-Untersuchung und -Forschung, 1995
Acids known to be decomposition products of carbohydrates were quantified in raw, dried and roasted chicory roots and in dried and roasted barley malt by means of gas liquid chromatography/mass spectrometry and isotachophoresis. Acids derived from other educts will be dealt with in following papers.

Bitter sesquiterpene lactones from chicory roots

Journal of Agricultural and Food Chemistry, 1990
Five known and one new sesquiterpene lactones were isolated from fresh chicory roots (Cichorium intybus). The new compound 11(S),13-dihydrolactucopicrin was identified by UV, 1 H NMR, 13 C NMR, and mass spectroscopy. The extraction procedure and HPLC analysis of sesquiterpene lactones in chicory were improved.

Release of inulin by enzymatic liquefaction of chicory roots

Food Chemistry, 1985
Abstract During liquefaction of chicory roots with commercial pectolytic and cellulolytic enzymes the release of inulin has been followed with high-performance liquid chromatography. For the release of inulin pH 4·6-4·0 is optimal: almost all inulin is present in the liquid phase (supernatant).

Extraction of sugars from forced chicory roots

Biomass Conversion and Biorefinery, 2019
The extraction of fructan and sugars from chicory roots is promising with regard to the production of 5-hydroxymethylfurfural. In this study, the extraction of chicory roots after the salad production was investigated for the first time in order to determine the extraction kinetics.

Isolation and characterization of fructosyltransferase from chicory roots

Phytochemistry, 1971
Abstract The occurrence of fructosyltransferase was demonstrated in the roots of chicory. The enzyme was purified 14-fold by ammonium sulphate fractionation and sephadex column chromatography. The optimal conditions for activity were pH 5·6, 37° and substrate (sucrose) concentration of 5·84 × 10 −1 M.

Chemical Modification of Chicory Root Inulin

1993
ABSTRACT Some methods of derivatization used for chemically modifying starch were applied to inulin in order to improve its functional properties. Attempts were made to esterify inulin with sodium trimetaphosphate and with a mixed acetic/adipic acid anhydride. Using these bifunctional reagents esterification of inulin proved to be possible.

Airflow through Beds of Apples and Chicory Roots

Biosystems Engineering, 2004
Abstract Pressure drops through batches of apples and chicory roots were measured. The results were correlated by means of Darcy–Forchheimer equations. The equations were modified to incorporate the effect of shape, surface roughness and confinement based on physical considerations. The confinement parameters were determined by means of computational
