Abstract
A composition and method for clarification of extract from sugar-bearing plants is provided. In particular, the composition comprises a mixture of one or more natural adsorbing actives and one or more inorganic coagulating or flocculating agents. The composition can be a solid or an aqueous suspension that is added to the aqueous stream of a sugar clarification process used in sugar bearing plants.
Claims16
An aqueous sugar-containing composition comprising:
- a) an adsorbing compound chosen from keiselguhrs, kaolins, zeolites, montminrollites, attapulgites, palygorskites, bentonites, clays, volcanic ash, and combinations thereof;
- b) an inorganic coagulating agent;
- c) a plant extract comprising sugar;
- and
- d) water.
A method for improved clarification of a plant extract comprising sugar, water, and impurities, said method comprising:
- providing the plant extract;
- combining the plant extract with
- a) an adsorbing compound chosen from keiselguhrs, kaolins, zeolites, montminrollites, attapulgites, palygorskites, bentonites, clays, volcanic ash, and combinations thereof;
- and
- b) an inorganic coagulating agent, to form an aqueous sugar-containing composition;
- and
- separating the impurities from the aqueous sugar-containing composition.
A method for reducing the amount of lime consumption in the clarification of a sugar-bearing plant extract comprising
- a) providing a sugar-bearing extract comprising sugar and water;
- b) adding to the sugar-bearing extract a composition comprising:
- an adsorbing compound chosen from keiselguhrs, kaolins, zeolites, montminrollites, attapulgites, palygorskites, bentonites, clays, volcanic ash, and combinations thereof;
- and an inorganic coagulating agent.
