Pectins are the most preferred gelling agents for acidic fruit gels because of being acid stable. To overcome the limitation of high methoxyl pectin, low methoxyl pectins (both commercial and amidated types) are used in the preparation of reduced sugar jams and jellies.Gelling agent: The agent is guar or xanthan gum or hydroxyethyl cellulose. Guar, which is by far the most used of these agents, is a polymerized disaccharide of mannose and galactose. This is rarely used for shale gas but routinely used for shale oil or when there is high condensate cut in the shale gas.
