What is good about this walnut oil

Fatty acids: More than 90% unsaturated, with omega-6 linoleic acid and omega-3 alpha-linolenic acid. The body cannot make alpha-linolenic acid, so it has to come from food.
Cold extraction: Extracted with supercritical CO2 at 36.8 °C. No high heat and no organic solvents, so the oil keeps the walnut’s own aroma.
Taste: Clear in color, with a light nutty aroma that does not overpower the dish.
How to use: On salads and cold dishes, over rice and noodles, to finish soups and steamed dishes, or for gentle cooking. Not for high-heat stir-frying or deep-frying.
Certification: China organic certification for farming and processing, grade 1 under the national walnut-oil standard (GB/T 22327), with test reports from the Kunming Customs Technology Center.
A long habit: People in Yunnan have used walnut oil for centuries. Traveling through western Yunnan in the Ming dynasty, Xu Xiake noted that the oil people cooked with and burned in their lamps was walnut oil.

About these origins

Dali: Yangbi is one of the places the species began: walnut wood 26,000 years old has been found here. More than 200,000 trees are over a century old, and the Yangbi Dapao cultivar has been grown here for over 1,600 years.
Chuxiong: Dayao County has grown walnuts for more than 2,000 years; its oldest tree is over 1,000 years old and more than 36,000 trees are over a century old. The Santai (“103”) cultivar was selected in Dayao’s Santai township.
