Detailed Introduction

Controlled Release:  
Gradual citric acid release sustains consistent acidity, ideal for extended storage & transport.

Improved Food Quality:   
Preserves texture, color, and freshness of processed foods.

Prevent Adverse Reaction:   
The encapsulation layer isolates citric acid from direct contact with other raw materials, preventing premature reactions with sensitive ingredients to avoid spoilage or performance degradation. 
Citric Acid Powder F85: Fat-coated, suitable for confectionery, bakery and other fields.  

Application Case: Candy Dusting Powder

As candy dusting powder, encapsulated citric acid boasts exceptional moisture resistance. It effectively inhibits moisture absorption during candy production and storage, markedly lowering the risk of adverse chemical reactions like sugar inversion. Additionally, it imparts a long-lasting sour flavor. INNOBIO’s encapsulated citric acid stayed dry even when open at room temperature for one month, showcasing outstanding real-world application performance. 

Citric Acid Powder H95:  
Water-soluble grade, suitable for effervescent tablets, effervescent powders, solid beverages, etc.  
Application Evaluations: Hygroscopicity test; Gas production and bag swelling test (encapsulated acid mixed with alkaline raw materials)

 

Test results show microencapsulation technology reduces citric acid’s moisture absorption capacity in humid and hot environments, effectively extending product shelf life.
