Glucomannan - Reference Information
| Introduction | Glucomannan is milky white or light brown yellow powder, basically odorless and tasteless, can be dispersed in acidic hot or cold water, heating or mechanical stirring can improve its solubility, in the solution to add a certain amount of alkali, can form a stable Sol, the consistency of the aqueous solution is very high. Mannan is a kind of natural high molecular weight water-soluble polysaccharide, which has many-OH Molecules, hydrophilic compounds, soluble in water, but insoluble in methanol, ether and other organic solvents, and its swelling is good, the water absorption can reach about 100 times of their own quality. Konjac glucomannan has a unique gel properties, in the non-alkaline conditions can produce a strong synergistic effect with carrageenan, xanthan gum, starch and other complex, so that the solution viscosity increases. |
| Use | used as a food additive and also used in oil field drilling |
| production method | fermentation medium containing sugars (such as glucose, sucrose, starch, hydrolyzed starch, etc.), in the presence of suitable nitrogen source, dipotassium hydrogen phosphate and appropriate amount of trace elements, the fermentation was carried out by Xanthomonas campestris, and then after extraction, drying, grinding and other processes. [Preparation method] the pH value of the medium containing 1%-5% glucose and inorganic salt is adjusted to 6.0-7.0, and then the inoculum of Xanthomonas campestris is added, and the culture is carried out for 50-100H, A high-viscosity liquid of 4-12PA. S can be obtained. After 48-60H of fermentation at 30 ℃, the cells were inactivated by heating to 70-80 ℃, then diluted hydrochloric acid was added to adjust the pH value to 2, and isopropanol or ethanol was added to precipitate the cells, then dried. |
