What is Konjac?
Konjac, also known as glucomannan, is an herb that grows in parts of Asia. It is known for its starchy stalks, the tuberous part of which grows underground. The stalks are used to make a rich source of soluble dietary fiber.
What is Konjac Flour?
Konjac flour is the generic name for konjac powder, which is made by grinding dried konjac. According to the purity of glucomannan, it can be divided into
- ordinary konjac flour,
- konjac gum,
- konjac glucomannan
three kinds.
The color of konjac flour is an important item to determine the quality of konjac flour. The whiter the color, the higher the glucomannan content.
What is Konjac Gum?
Konjac gum, also known as purified konjac powder, is a water-soluble hydrocolloid that is extracted with water from konjac powder. Konjac powder is the unpurified raw material from the roots of the perennial plant Amorphophallus konjac.
What is Konjac Glucomannan(KGM)?
Glucomannan is produced by washing konjac with watery ethanol because it readily absorbs water and is insoluble in ethanol. Glucomannan is a water-soluble polysaccharide that is considered a dietary fiber. It is a hemicellulose component in the cell walls of some plant species. Glucomannan is a food additive used as an emulsifier and thickener. From Wiki.
The main difference between konjac gum and konjac glucomannan is the purity of the glucomannan in them (glucomannan is dietary fiber and is the main functional ingredient in konjac flour).
This content needs to be ?75% in konjac gum and 95% or more in konjac glucomannan.

Funciones
La goma konjac es fácilmente soluble en agua fría y la solución presenta un alto grado de fluidez pseudoplástica.
Su viscosidad es muy estable en una amplia gama de pH y temperatura, y el polisacárido es resistente a la degradación enzimática.
La goma konjac presenta una interacción sinérgica con galactomananos como la goma guar, la goma garrofín y la goma konjac.
El resultado fue una mayor viscosidad de la goma guar, mientras que los geles termorreversibles de la goma LBG y la goma konjac eran blandos y flexibles.
Espesantes y gelificantes para una amplia variedad de alimentos.
Un sustituto vegano de la gelatina.
Se compone de 85-90% Glucomamman y se utiliza en Asia para crear una harina y una gelatina de alta viscosidad.
Es sinérgico con kappa carragenina y goma xantana formando geles elásticos termorreversibles.
Konjac Gum Properties
Solubilidad
The large molecular weight reduces the solubility of konjac in water, but the presence of a large number of hydroxyl groups in the molecule allows it to absorb about 80-100 times its own amount.
Viscosity - Maximum Viscosity
1g of konjac dissolved in 100g of water, can produce 20,000cps ~ 40,000cps viscosity, in the same concentration of thickeners, such as carrageenan, xanthan gum, gum arabic and other viscosities.
Compared with thickeners such as guar gum, xanthan gum, locust bean gum, etc., konjac is a non-ionic polysaccharide and is less affected by salt ions (calcium, potassium or sodium ions) in viscosity and gel structure.
The high viscosity allows it to be used as a thickening agent in sauces, soups and condiments.
Sinergia
With xanthan gum, starch and other thickeners have good synergistic thickening effect. Such as 1% xanthan gum and 0.02% ~ 0.03% konjac used in conjunction with, solution viscosity can be increased by 2 ~ 3 times. 4.5% modified corn starch and 0.5% konjac mixed solution viscosity is 4.5% modified corn starch 4 ~ 9 times. Therefore, the number of other thickeners can be reduced if used with konjac in food.
Gel
- Thermally irreversible gel
Konjac can form thermally irreversible gels under alkaline conditions (e.g., calcium hydroxide). The degree of gelation of water depends on the presence of acetyl groups in its molecules.
The gel is formed as a result of the removal of acetyl groups by alkali and heat. The gels are thermally stable and are acid and salt stable even after repeated heating at 100°C.
This property can be used to produce heat-free noodles (teriyaki), tofu, rice, pudding, etc. and its flavor can be encapsulated in such konjac products.
- Thermally reversible gel
When heated, konjac can form thermally reversible gels when combined with solutions of xanthan gum, gellan gum, carrageenan or other hydrocolloids. This is due to the synergistic effect of gelation.
Konjac Gum Benefits
Several studies have found that konjac gum can lower blood sugar, and some other potential health benefits, such as Lower cholesterol, Weight loss, Cancer-fighting properties, Improved regularity, Thickens liquids, Saliva substitute. More human studies are needed.
Konjac Gum Uses
- Aplicaciones
Konjac can form a thermally irreversible gel so it is commonly used as a gelling agent in heat-stable and thermally reversible gelling foods. Such as: Noodles, jams & Jellies, Pasta and prepared meal.
It is also used as a thickener and stabilizer for bread, cakes, meat products, ice cream and beverages due to its excellent viscosity performance.
Konjac in Meat:
Konjac is used as a binder in meats for its thickening, emulsifying, water retention and gelling properties. It is also often used as a fat substitute in sausages and hams, for example. It enhances water retention, improves meat texture, and reduces fat content.
Konjac in Starch Products:
Konjac improves the gelatinization, rheological and textural properties of starch through cross-linking, agglutination and other reactions with starch. These properties are closely related to the texture, taste and quality of food. The mixture of starch and konjac has a better thickening effect and stability. Also, the gel formed by the mixture has low hardness and elasticity.
The addition of konjac to instant rice improves the texture and brings the taste closer to that of fresh rice.
Thanks to the property of thickening and water-retaining, konjac gum is widely used in the food industry.
One might find Konjac in flour products, meat and dairy products or beverages.
En productos cárnicos, konjac is used to prevent water loss to extend shelf life.
En jaleas, konjac can be used to make the jellies more chewy and elastic.
En chewy candies, konjac is used to prevent crystallization and soften the products.
