Black goji berry is a common medicinal herb, containing nutrients such as amino acids, vitamins, and proteins. It has the effects of nourishing the liver and kidneys, and calming the mind. It is suitable for symptoms such as weak lower back and knees, insomnia, and nocturnal emissions. Wild black goji berry is expensive, and there are many counterfeit products on the market. So, how can we distinguish between genuine and fake black goji berries?
Take a look
Black goji berry is a natural wild herb, containing active ingredients such as black goji berry polysaccharides, anthocyanins, and proanthocyanins. Black goji berries are flat oval-shaped, resembling kidneys, while common counterfeits like white lycium berry are elongated oval-shaped. Black goji berries have many fruit seeds, and when crushed, you can see about ten small seeds, whereas white lycium berry only has one seed inside.
Give it a taste
Black goji berry is a nourishing herb and has a slightly sweet taste with a hint of astringency. The counterfeit black goji berries commonly sold on the market are primarily white lycium berries. They lack the dark purple color of black goji berries and have a higher sugar content, resulting in a sweeter taste. Therefore, when purchasing black goji berries, it's worth giving them a taste. If the taste is overly sweet, it's likely a counterfeit black goji berry.
Soak it
Black goji berries contain abundant anthocyanins, which are sensitive to acidity and alkalinity. They appear purple in acidic water and blue in alkaline water. When black goji berries are soaked, the color gradually fades as the anthocyanins are released. After soaking for a long time, they turn translucent. Counterfeit black goji berries will not show any color changes when soaked in water.
Consider the price
Black goji berries are rich in nutrients and contain various active ingredients, making them highly valuable in traditional medicine. They are known as the "golden supplement". Wild black goji berry resources are scarce and have a low yield, hence the high price. Generally, black goji berries that are priced too low are mostly counterfeit. It is recommended to purchase from reputable sources.
