|Konjac gum is obtained from the tubers of the amorphophallus konjac plants, and its |
impurities are separated by mechanical separation. It consists mainly of glucomannan,
which is composed of glucose and mannose subunits lined with ?-1, 4 linkages at a ratio of 1.0:1.6. Glucomannan is a slightly branched polysaccharides with a molecular weight of 20,000 to 2,000,000 daltons.
Researches show that it is a kind of plastic-like fluid and has nice water solubility. It is glutinous, shapeable and has good coagulability and adherence ability. What s more, konjac can be mixed with some macro-molecule materials under certain prerequisites and yield many products of different uses. Therefore, konjac is promising in varied fields, such as food industry, medicine industry, chemistry industry, oil industry, printing and dyeing industry, geology, building materials, agriculture, environmental protection, aviation and so on.
Especially in European counties, it can be used for cured meat, canned food, and
starch food, helping to make the products emulsify and thicken, and developing stableness.
Until now, konjac is the best soluble dietary fiber that has been discovered. It is good for people s health, and is popular in Southeast Asia. Konjac powder is used in jelly or as a cooking supplement for soups and stewlike dishes. Konjac powder will be a food additive with great contribution for this century. It is a multifunctional natural food supplement and superior ingredient of composite additives.
1) Can expand to about 100 times its original volume when mixed with
2) It is a kind of white or light cream powder that dissolves quickly in water
3) Can be used as a gelling agent, thickener, film former, emulsifier and
stabilizer, and can be at even p H <3.8
4) Can synergize with kappa carrageenan, xanthan gum and locust bean
gum. So it can reduce the production cost, and improve its quality
Method of test viscosity:
1) 1% aqueous solution at 25° C
2) Uses the NDJ-1 viscometer (made in Shanghai Scale Instrument Factory)
3) No. 4 spindle, 30r/min
25kg/strong poly-bag per carton
