PRODUCT RANGE AND PROPERTIES

GENU^® pectin type USP/100 forms gels under both hot and cold conditions. Low pH (below about 3.8) and
low water activity (a high concentration of polyhydric alcohol, e.g., sorbitol, glycerol or glycol) are required
for gelation. The gels sag under their own weight and may be extrudable.

Another important property of USP/100 is its ability to absorb and bind water.

GENU pectin type X-907-02 is non-gelling with a high water absorption capacity. When dispersed in an aqueous medium, the particles instantly swell, becoming soft and deformable. Interesting rheological effects are obtained if the dispersion is then sheared to break down the swollen particles.

GENU pectin type X-915-02 is non-gelling. It is useful as a thickener and has emulsification properties.

GENU pectin type X-920-02 and X-916-02 form gels in the presence of divalent cations, such as calcium and magnesium. The gels are firm and relatively brittle. Of the two products, X-916-02 is somewhat easier to use, as it forms good quality gels over a wider range of gelling ion concentrations.

GENU pectin type X-914-02 has properties similar to those of a pectate. It is more stable in alkaline and neutral pH media than more highly esterified pectins, which are unstable at pH values above 5. The addition of an acid or a divalent metal salt to a solution of X-914-02 produces a gelatinous precipitate. Like other pectin products, X-914-02 has useful film-forming properties.

As well as offering the products listed above, CP Kelco works in conjunction with customers to develop newpectin products and formulations for specific applications.
