What You Need to Know
Konjac glucomannan forms a gel network through alkaline-induced deacetylation, typically using calcium hydroxide or sodium carbonate. The gelation involves molecular chain alignment and hydrogen bond formation.
Valued for its chewy texture and ability to carry flavors while being low-calorie and high in dietary fiber.
