The role of desiccant in packaging cannot be ignored. It cooperates with the use of various packaging materials to reduce the corrosion and damage of water vapor to health food in the natural environment, so that health food can be kept fresh and not deteriorated during the shelf life.

At present, the commonly used desiccant is silica gel. It itself is granular and is mainly used in the form of plastic cylindrical cans or bags in packaging. With the enhancement of people's awareness of health care, various green health foods that enhance physical fitness and regulate physiological balance emerge in an endless stream. Because of its safe chemical properties, high safety, non-toxic and non-corrosive, silica gel has been approved by the US FDA agency for use in the food and pharmaceutical industries.

The packaging of health food is changing with each passing day, it not only requires beautiful and novel, but also pursues individualization. As an auxiliary product for packaging, green environmental protection desiccant is becoming more and more important. It prolongs the shelf life of the product while preventing moisture and guaranteeing quality, and relatively improves the value of the product. Compared with the traditional silica gel desiccant, it has some completely new concepts.

In the future, my country's desiccants will develop in the direction of diversified forms, superior performance and environmentally friendly products. These three development trends of desiccant are the trend of the world. It is believed that under the impetus of it, my country's health food desiccant will steadily advance in these three development directions, and gradually become a precedent in the world.
