**8.4 Drying**

The drying stage was carried out in a forced air oven at a temperature of 80° C with a time of 3 hours until a humidity of 8% is achieved (**Figure 7**).

## **8.5 Grinding**

The milling was carried out with a hammer mill; this allows to reduce the size of the particles of the quinoa seeds, which allows us to break the cells, which makes the release of the oil feasible. In addition, the average size is 240 u of the particles (**Figure 8**).
