Wet Milling Method: The Secret Behind Yanokuni Innocent Rice Flour’s Silky Texture

"Yanokuni Innocent Rice Flour" is Made with the Wet Milling Method

Rice is much harder than wheat, which means it requires specialized equipment for milling. There are two primary methods for producing rice flour: wet milling and dry milling.
What is Wet Milling?
Wet milling involves soaking the rice in water to soften it before grinding. This process produces rice flour with uniform particle size, a fine texture, and minimal starch damage. As rice flour becomes more popular, more manufacturers are entering the market. Still, Yanokuni Innocent Rice Flour stands apart by committing to quality through the wet milling method, which requires more complex facilities and costs.

Jet Mill Technology

Our flour mill for wet milling uses a self-pulverizing system, where rice grains collide with each other to break down. This method keeps impact force low and shortens milling time, resulting in less heat building up and no risk of starch gelatinization (alpha modification). The result? A fine, evenly milled rice flour with sharp particle size distribution and minimal starch damage.

Wet Milling with "Noana” Water

For washing rice before milling, we use water purified by Noana®, NETIN Co., Ltd.’s original water filtration system. This system uses three types of activated carbon that removes lead and eight types of carefully selected ceramics to enhance tap water to taste as fresh and clean as natural spring water. Although Noana we use at the facility is a large commercial type, Noana originally was developed as a water purifier for household, and it is widely used in households across Japan.

In summary, a key feature of Yanokuni Innocent Rice Flour is that it’s made from carefully grown rice, washed with Noana-filtered water during the milling process.
