Why Is Green Tea Powder So Smooth and Fine?
Introduction
When you open a packet of store-bought green tea powder, you may be surprised by how smooth and free-flowing it feels. Many people expect tea powder to be coarse or gritty. In this article, we’ll explore the reasons behind the fine texture of green tea powder, focusing on manufacturing techniques and ingredients.
Particle Size and Micro-Pulverization
Green tea powder is made by pulverizing tea leaves into very fine particles. Most products are adjusted to have an average particle size of around 10–50 microns (μm). This micro-pulverization creates a fine, smooth appearance and helps the powder dissolve easily.
The Role of Excipients
To prevent the powder from clumping, some products include excipients—substances that improve powder flow. One common example is dextrin, which helps control moisture absorption and keeps the powder free-flowing.
- Dextrin: A water-soluble polysaccharide that improves powder fluidity.
- Silicon dioxide, for example, may also be added to enhance flowability.
Drying Process Optimization
The drying stage of the production process plays a key role in the powder’s texture. Well-dried tea leaves and sugars are less prone to moisture absorption, keeping the final product dry and smooth.
Techniques like spray drying or atomized drying help create uniform, fine particles with good dispersibility.
Storage Conditions Matter
Even finely processed powder can become clumpy if stored in humid environments. That’s why many packages include a desiccant. After opening, be sure to seal the bag tightly and store it in a dry place to maintain quality.
Conclusion
The smooth texture of green tea powder is the result of fine particle size, excipients, and drying techniques used during manufacturing. Paying attention to storage methods will help maintain its quality and ensure a pleasant tea experience.
