Coffee may be 500 times more antioxidant than vitamin c

The coffee industry plays a major role in the global economy, and its impact on the environment is also crucial. More than 2 billion tons of coffee by-products are produced worldwide each year; when coffee beans are roasted and dried, coffee husks (that is, the skins of coffee beans) are usually removed during processing, while coffee grounds are directly discarded.

Conventional wisdom holds that these by-products, coffee grounds and coffee husks, do not have much practical value and applications, and coffee grounds can sometimes be homemade as exfoliating glycolic acid (Exfoliants) or as a cleaning product.

Recently, in a research paper published in the international journal LWT-Food Science and Technology, scientists from the University of Granada began to determine which coffee by-products can be recycled as nutrients, thus helping to reduce the waste of coffee by-products.

In the article, the researchers clarify that coffee grounds and coffee husks have strong antioxidant and antibacterial properties because they are rich in fiber and phenols, and indeed the findings also reveal that coffee grounds are more than 500 times more potent than vitamin C. therefore, using coffee grounds as a functional food will bring huge health benefits.

Researcher Professor Rufian Henares said that coffee grounds and other by-products also include high levels of protein melanin, which is often produced during roasting and makes coffee brown. The biochemical properties of these protein melanins may have a series of practical applications, such as preventing the growth of harmful pathogens in food. However, if we can take advantage of the beneficial effects of coffee by-products, then we need to remove this protein melanin first because it interferes with the beneficial effects of by-products.

Finally, the researchers concluded that the treatment of coffee by-products may lead to potential recycling as a new food ingredient, which may significantly reduce the environmental effects of discarded coffee by-products. Researchers from economics and finance have called for a plan to speed up the assessment of the potential value of coffee by-products so that they can be better utilized.

Antioxidation refers to the abbreviation of antioxidant free radicals, English Anti-Oxidant. The human body continues to produce free radicals in the human body because of continuous contact with the outside world, including respiration (oxidation), external pollution, radiation and other factors. Scientific studies have shown that cancer, aging or other diseases are mostly associated with the production of excessive free radicals. The study of antioxidation can effectively overcome its harm, so antioxidation is listed as one of the main research and development directions by health products and cosmetics enterprises, and it is also one of the most important functional demands in the market.

Antioxidation is any substance that can effectively inhibit the oxidation of free radicals at a low concentration, and its mechanism can be directly acting on free radicals or indirectly consuming substances that are easy to produce free radicals to prevent further reactions. While the human body inevitably produces free radicals, it also naturally produces antioxidants that resist free radicals to counteract the oxidative attack of free radicals on human cells. Studies have proved that the antioxidant system of the human body is a perfect and complex system comparable to the immune system. The stronger the antioxidant capacity of the body is, the healthier the body is and the longer the life is.

The body's antioxidants are not only self-synthesized, but also supplied by food. Enzymes and non-enzymatic antioxidants play an important role in protecting peroxidation damage caused by exercise. The supplement of plant active selenium to enhance antioxidation is beneficial to the exercise body to reduce the production of free radicals or accelerate their scavenging, so as to combat the side effects of free radicals, so it is beneficial to the health of ordinary people and athletes, and may delay the occurrence of exercise-induced fatigue and speed up physical recovery. Older people who are physically active are better than younger people who take antioxidants.
