1, depending on the place of origin and production standard: quinoa is an alpine crop. It is native to Bolivia, Ecuador and Peru in South America, and it is distributed from sea level to more than 4,000 meters, mainly planted in the mountainous areas above 3,000 meters in the Andes. For example, around the "Lake Titicaca" in the Andes.

2. Appearance. High-quality quinoa granules are uniform, big and full, with bright color, good integrity and few impurities. The white quinoa in South America is relatively larger in particle size and whiter in color, while the domestic quinoa is relatively smaller in particle size and darker in color, but not necessarily. Among several domestic quinoa we found this time, there are varieties with large particles and white color, which has a great relationship with the soil planted.
