Dietary Fiber was officially introduced into the nutrition field and classified as the seventh nutrient.  The standard recommended by the Chinese Nutrition Society is 25-35 grams of dietary fiber per person per day.  

 As a branch of dietary fiber, water-soluble dietary fiber has been widely used in food in recent years.  

 In addition to the healthy concept of fiber, water-soluble dietary fiber is widely used because of its own functional characteristics.  As a new type of dietary fiber, thickener, expansion agent, formula agent and filler, water-soluble dietary fiber is widely used in low energy, high fiber and other functional foods.  

 In low-energy foods, water-soluble dietary fiber can partially or completely replace sugar and fat, reducing the energy of food while maintaining the original flavor and texture of food, bringing a satisfactory taste.  

 In addition, water-soluble dietary fiber is widely used in beverage, dairy products, confectionery, baking and other food fields due to its good solubility, stability and mild taste.
