Black may be the colour of evil, even in Chinese culture, but for food it is a sign of superior nutrition
Black food has become a focus in the Chinese health food market in recent years. Black food refers to the natural melanin containing foods, whether derived from animals or plants. The natural melanin content causes a dark, dark purple, or dark brown colour. Some foods have a dark skin, while others are black at the end, inside or outside, such as black goji, black rice, black sesame seeds, black fungus, mushrooms, seaweed, kelp and laver. Manufactured black food, such as plum sauce, bean curd, soy sauce, cured egg etc., are meant to stimulate people’s appetite through their colour, but do not count as real black food.
The scope of what counts as black food is not strictly defined. The Guangdong Academy of Agricultural Biotechnology is one of the earliest domestic research institutes specialising in black food. It defines black food as having a relatively dark natural colour, rich in nutrition, and structurally acceptable to the human physiology as food. This definition excludes artificially black foods such as soy sauce.
Black foods contrast with food groups of other colours:
- White food: bread, noodles, etc.; main nutrients: starch, sugar and other carbohydrates;
- Red food: pork, beef, lamb, chicken and rabbit; main nutrients: protein, fat;
- Green food: green vegetables and fruits; main nutrients: a variety of vitamins and cellulose;
- Black food: black rice, black beans, turtle, black fungus, black mushrooms; main nutrients: protein, fat, amino acids, vitamins.
According to traditional Chinese medicine (TCM), black foods nourish the kidneys. They are rich in anti-oxidants and can therefore prevent several types of cancer and slow down aging. They strengthen the brain and lower blood pressure. The fact that shining black hair has always been regarded as a sign of physical health in China certainly also plays a role in the positive image of black foods in China.
Five Black Elements
The most conspicuous producers of black foods in China is the Five Black Elements (Heiwulei) Group in Guangxi. The company was founded in 1984 as the Nanfang Children’s Food Factory by Mr. Wei Qingwen. The name Heiwulei was adopted a decade later. The term itself originates from the Cultural Revolution, denoting five types of bad people (‘black categories’) in society: landlords, rich farmers, counter-revolutionaries, bad elements, rightists. Mr. Wei loved black sesame paste, which was his company’s first product. Now, the company is producing ‘Eight Black Treasures’ (Heibazhen): black rice, black beans, black fungus, black mulberry, black corn, black dates, black sesame and black seaweed (laver).
