6. Frequently Asked Questions
Q: What are the manifestations of the product's superior anti-caking property?
A: The 15μm medium particle size is adapted to the characteristics of coarse powder food. After addition, it can effectively block the adhesion between powder particles, completely solve the problem of hard caking of coarse powder food during long-term storage and transportation, with an anti-caking shelf life of 24 months.
Q: Will addition affect the subsequent processing of food?
A: No. This product is inert to all food ingredients with stable performance in the full temperature range. It does not change the physical and chemical properties of food after addition and has no impact on subsequent processing processes such as baking and reconstitution.
Q: Are free samples available?
A: Yes, free samples are provided for customers to conduct small-scale tests, and our technical team provides full-process technical support.
