Dietary fiber is a polysaccharide that cannot be digested or absorbed by the gastrointestinal tract, nor does it produce energy. As a result, it was once considered a "non-nutritive substance" and was long overlooked.

It is widely found in plants in nature, such as bananas, onions, garlic, etc. It is an excellent water-soluble dietary fiber with various physiological functions and unique health benefits, often referred to as the "third-generation golden bifid factor."

It plays a key role in modern animal husbandry and the feed industry. It is a nutrient that animals cannot synthesize on their own but is essential for their growth, development, reproduction, and other physiological processes, making it irreplaceable.

Protein milk-based powder/solid beverage is a powdered product primarily made from glucose syrup and milk powder as the wall materials, plant oil as the core material, using microencapsulation technology. It is produced through processes such as emulsification, shearing, homogenization, and spray drying, and is considered a type of food.

Erythritol is a natural sugar alcohol sweetener that is widely found in algae, mushrooms, melons, grapes, and other plants in nature, as well as in the human eye and serum. It is also present in small amounts in fermented foods such as wine, beer, and soy sauce.

Starch syrup is a type of sugar widely used in the food industry, primarily produced by the hydrolysis and conversion of starch through chemical processes. Its characteristics include a good sweet taste and relatively low calories, which is why it is increasingly being used as a substitute for traditional sugars in many food products, gaining more attention.

As a polyhydroxy carboxylate sodium, it has good thermal stability and is non-hygroscopic. Due to its excellent chelating properties, it is widely used in water treatment, electroplating, surface cleaning of metals and non-metals, cement production, and other industrial sectors. It has a wide range of applications in industries such as chemicals, food, pharmaceuticals, and light industry.
