AI Technical Summary

Problems solved by technology

The squeezed walnuts contain a large amount of unsaturated fatty acids, some linoleic acid, and rich in natural VA, VD and other nutrients, which can eliminate the metabolic impurities in the blood vessels, purify the blood, and provide fresh blood for the brain. Nutrient elements of walnut oil Although high, the existing pressing methods will destroy the multiple nutritional and beneficial ingredients in walnuts, greatly reducing the nutritional and health value of walnut oil
