How Sweetened Matcha Powder Is Manufactured

It sounds like mixing matcha with sugar. Blending two powders uniformly is harder than it looks.

Particle size mismatch causes separation

Matcha particles run 1 to 10 microns. Sugar crystals are far larger.

Mix components of very different size and vibration during transport separates them into layers — sugar toward the top, matcha toward the bottom. Open the package and the composition of each scoop differs.

That has to be prevented.

Blending

Industrially, dedicated powder mixers run for extended periods.

The ratio is fixed here. More matcha means more tea character; more sugar means sweetness forward and lower cost. This step determines what the product is.

Granulation

Rather than shipping loose powder, some manufacturers form it into granules.

A small amount of moisture is introduced to bind particles into clusters, which are then dried. The result separates less and dissolves more readily.

Fine powder wets only on its outer surface, forming a barrier that keeps the interior dry — the mechanism behind lumps. Granules let water penetrate. Instant coffee is granulated for the same reason.

Flow agents

Dextrin serves a similar purpose. It keeps powder free-flowing and prevents caking.

Produced by breaking down starch with acid or enzymes, it is a food ingredient rather than an additive, though it counts as carbohydrate.

Filling and packaging

The blend goes into bags, tins, or sticks.

Because powder is moisture-sensitive, this happens in humidity-controlled conditions. Oxygen absorbers, nitrogen flushing, and light-blocking materials may follow.

Some products skip most of this

Ingredient lists reading only "matcha, sugar" indicate no granulation and no flow agents.

Such products clump more readily. In exchange, the list of what you are consuming is shorter. It is a design decision, not a quality ranking.
