WebPectin is a group of substances derived from the cell walls of fruit. These pectins form gels when dissolved in water under suitable conditions. Adding dry pectin (without blending the pectin with sugar) to water results in the formation of paste-like lumps that are nearly impossible to dissolve. the derschang groupWebPECTIN - ROLE IN GEL FORMATION Pectin is the term designated to those water-soluble pectinic acids of varying methyl ester content.

Upon cooling below gelling temperature, a gel starts to form. If gel formation is too strong, syneresis --the extraction of the liquid component-- occurs possibly producing a granular texture. Weak gelling leads to excessively soft gels. the deruga case
