Apr 28, 2023

Hydrocolloids are widely used. In addition to the food industry, there are other industries, such as the cosmetics industry, toothpaste manufacturing industry, tobacco manufacturing industry, pharmaceutical manufacturing industry, etc. It can be said responsibly that the hydrocolloid market prospect is still very broad.

With the continuous improvement of people's living standards, people's requirements for food are also changing all the time. In the era of scarcity of materials, people are more concerned about having enough to eat, but now, people are more concerned about the naturalness, nutrition and multi-function of food.

In frozen food, adding hydrophilic colloid can increase the viscosity, improve gelation, prevent or inhibit the increase of particle ice crystals, delay the appearance of ice slag, improve the taste, internal structure and appearance, and improve system stability and melting resistance. .

Adding hydrophilic colloids to jelly candies can make the soft candy taste smoother, more elastic, less viscous and more stable, with strong fruity flavor, moderate sweetness and good transparency. The application of hydrocolloids in beverages and foods can improve the stability of the pulp, make the juice taste thicker and taste better, and also stabilize the oil components in the ju
