A Complete Introduction to the Origin Distribution and Cultivation Conditions of Black Peanuts

Black peanut is a distinctive peanut variety whose seed coat is deep purple-black; it gets its name because the seed skin is rich in pigments such as anthocyanins, and its biggest visual difference from ordinary peanuts is this dark-colored seed coat. Its plant form and cultivation methods are similar to those of ordinary peanuts, and its taste is similar as well, so it is often used as an ingredient or as a raw material for processed products.

In terms of origin distribution, black peanut has adaptability similar to that of ordinary peanuts and prefers warm, sunny, well-drained sandy soil, so it can be seen under cultivation in all major peanut-producing areas. In Taiwan, China, the coastal area of Yunlin is a major peanut-producing region, and local farmers also grow black-kernel varieties; after harvest, the crop mostly flows to nearby markets and processing plants. In mainland China, Shandong, Henan, Hebei and Yunnan also have black peanut cultivation, and sowing and harvesting times vary from place to place because of differences in climate and soil.

When selecting black peanuts, you can start with their appearance: those with evenly deep seed-coat color, plump kernels and no rancid or musty smell are best. Peanut products easily absorb moisture and spoil, so after buying them you should store them sealed in a cool, dry place, or divide them into portions and keep them refrigerated, to avoid quality loss caused by high temperature and humidity.

In terms of uses, black peanuts are eaten much like ordinary peanuts; they can be boiled, stir-fried or stewed in soup, and can also be used to make processed products such as peanut butter and peanut candy. Because the seed coat contains anthocyanins, the cooking liquid will take on a darker color when boiled, which is normal. Consumers who want to learn more about origin information can pay attention to origin certification labels or production and sales traceability when purchasing, for greater peace of mind when eating.
