When peanuts, melon seeds, hazelnuts, pine nuts and other nuts are found to be slightly yellow or even black, bitter, wrinkled and discolored, and the grain surface is covered with yellow-green mold or damaged, shrunk and discolored, they should be discarded. When storing nuts and grains, be sure to keep ventilation to prevent mold growth.

Among melon seeds, sunflower seeds are the best. Sunflower seeds can be used not only as snacks, but also as raw materials for making cakes. Because sunflower seeds are plant seeds and contain a lot of oil, sunflower seeds are still important raw materials for oil extraction. Sunflower seed oil is a high-grade healthy oil highly praised by nutrition circles in recent years.
Sunflower seeds are rich in unsaturated fatty acids, of which linoleic acid, which is essential for human body, accounts for about 50% ~ 60%. Sunflower seeds are rich in unsaturated fatty acids, but also contain a variety of vitamins, folic acid, iron, potassium, zinc and other essential nutrients. Sunflower seeds contain a lot of edible fiber, and every 7 grams of sunflower seeds contain 1 gram, which is much higher than the proportion of edible fiber in apples. The American Cancer Institute has proved in related experiments that dietary fiber can reduce the incidence of colon cancer.
The iron content in sunflower seeds is twice that of raisins and peanuts, so it can also prevent anemia. Another point is that protein of sunflower seeds contains arginine. Arginine is an indispensable component in semen production. Therefore, it is very beneficial for men in reproductive period to eat some sunflower seeds every day.
