Normal goji berries themselves contain carotene, a small amount of color loss is normal. Goji berries in moisture or see water there is pigment overflow. But these colors are plants own pigment. While some goji berries are refined material dyed, this color loss is not normal, so the color red goji berries appearing on the market should be distinguished.
1, from the color to identify
Fresh goji berries due to different places of origin and color, but the color is very soft, glossy, full flesh; and was dyed goji berries are more than the previous year's stale goods, from the sensory point of view of the flesh is poorer, no luster, the appearance of the bright and inviting, so buy goji berries must not greed "color", it is recommended to choose the first crop of the first year of goji berries. ", it is recommended to choose the first crop of summer wolfberry.
Particularly stained wolfberry the whole is red, even the wolfberry tip handle at the small white spots are also red, while the normal wolfberry tip at the tip of the more yellow or white, with pigment dyed wolfberry tip is red, baked with sulfur is bright red. Suggested that when you buy wolfberry you can put a dozen of wolfberry into the water, if the color does not fall off, it means that it is sulfur fumigation of wolfberry, because sulfur is not soluble in water. If red color appears, it means that coloring has been used. Normal color is orange (yellowish) and a small amount of flocculent floating.
2, from the shape to identify
Wolfberry since ancient times to ningxia wolfberry for real estate medicine, the highest medicinal value. Most of the ningxia wolfberry tip with small white spots, this field wolfberry is not, ningxia wolfberry tip with white spots can reach 85%. Ningxia wolfberry into the water 90% does not sink, no matter bubble tea, soup and so on are floating in the water. Ningxia goji berries and Inner Mongolia goji berries are oblong, but ningxia goji berries will float after soaking in water, Qinghai, Inner Mongolia goji berries will sink, and Xinjiang goji berries are round, easy to distinguish.
3, from the smell of identification
For the sulfur-fumigated goji berries, just need to grab a handful of hands covered for a while, and then put under the nose to smell, if you can smell the irritating choking flavor, then you can be sure that the sulfur fumigation.
From the taste to identify
Ningxia wolfberry is sweet, eat up especially sweet, but after eating a bitter taste in the throat; and Inner Mongolia, Xinjiang and other places of wolfberry sweet some greasy, alum soaked wolfberry chewing will have alum bitter, as for the fight over sulfur in the wolfberry, the taste presents sour, astringent, bitter feeling.

Effects and functions
Effective one: immune regulation
Wolfberries are rich in Lycium barbarum polysaccharide, Lycium barbarum polysaccharide is a kind of water-soluble polysaccharides, by the arabinose, glucose, galactose, mannose, xylose, rhamnose, the six kinds of monosaccharide components, with physiological activity, can enhance the non-specific immune function, improve the quality of life and improve the quality of life. It is physiologically active and can enhance non-specific immune function, improve disease resistance, inhibit tumor growth and cell mutation.
Effective two: anti-aging
Immune aging and apoptosis are closely related. Lycium barbarum polysaccharide (LBP), can significantly improve the phagocytosis function of phagocytes, improve the proliferation of lymphocytes.
Effective three: anti-tumor
Lycium barbarum polysaccharide is not only a kind of biological response modifier to regulate the immune response, but also can play an anticancer role through the neurological - endocrine - immune regulation network.
Effective four: anti-fatigue
Lycium barbarum polysaccharide can significantly increase the myoglycogen and hepatic glycogen reserves in mice, and improve the total activity of blood lactate dehydrogenase before and after exercise; reduce the increase in blood urea nitrogen after intense exercise in mice, and accelerate the rate of blood urea nitrogen clearance after exercise. This shows that LBP has a very obvious effect on eliminating fatigue.
Effective five: anti-radiation damage
Lycium barbarum has anti-Y-ray radiation, protection of the body, can be used as an adjuvant drug to cooperate with radiotherapy and other anti-tumor treatment, reduce the toxic side effects of radiotherapy, improve the efficacy of treatment, and to protect the immune function of the body.
Effectiveness of six: regulation of blood lipids
Wolfberry can effectively reduce the serum of rats suffering from hyperlipidemia triglyceride and cholesterol content, with obvious hypolipidemic, regulate lipid metabolism, on the prevention of cardiovascular disease has a positive effect.
Effective seven: lowering blood sugar
Liberty berry polysaccharide can obviously enhance the activity of superoxide dismutase (SOD) in the damaged pancreatic islet cells, improve the antioxidant ability of pancreatic islet cells, reduce the damage of peroxide on the cells, reduce the amount of endo-dialdehyde, which suggests that LBP has a certain protective effect on the pancreatic islet cells.
Effective eight: lowering blood pressure
Lycium barbarum polysaccharide can reduce blood pressure in rats (systolic and diastolic blood pressure are effective); reduce plasma and vascular malondialdehyde, endothelin content, increase the release of calcitonin gene-related peptide, prevent hypertension.
Effectiveness IX: protection of reproductive system
Lycium barbarum polysaccharide can make the serum sex hormone level of rats with testicular damage increase; increase the organ coefficient of testis and epididymis, improve SOD activity of rat testicular tissues, reduce the content of malondialdehyde, and make the damaged testicular tissues recover to near normal level.
Effective ten: improve eyesight
Human retinal photoreceptors are composed of retinol and retinal protein, wolfberry rich in B a carotene can be converted into vitamin A in the human body, and vitamin A can generate retinol, thus improving eyesight, preventing macular degeneration.
Effective eleven: improve respiratory resistance
Wolfberry is rich in carotene, can be converted into vitamin A in the body, with the maintenance of epithelial tissues normal growth and differentiation of the function of the amount of sufficient to prevent nose, throat, throat and other respiratory tract infections, improve respiratory resistance.
Effective twelve: beauty, moisturize the skin
Skin aging is mainly due to free radical oxidation caused by the wolfberry contained in the lycium barbarum polysaccharides, B a carotene are powerful antioxidants, plus wolfberry contains trace elements selenium and vitamin E synergism, composed of a powerful antioxidant force; in addition, vitamin A can maintain the growth of the epithelial tissues and differentiation of the skin, prevent dryness and follicular keratosis. , preventing skin dryness and follicle keratinization, thus playing a role in beauty and moisturizing the skin.
Effect thirteen: protect the liver
Anti-fatty liver berries contain betaine has inhibited the deposition of fat in the liver cells, promote the role of new liver cells. At the same time can prevent carbon tetrachloride-induced liver dysfunction, so the structure of the wolfberry has a clear protection of the liver, anti-fatty liver effect.
Effective fourteen: enhance hematopoietic function
Lycium barbarum contains lycium barbarum polysaccharide can protect the white blood cells, promote the body hematopoietic function recovery. In addition. Ningxia wolfberry also has the role of regulating neuroendocrine, repair ischemic brain damage, reduce cerebral edema, improve brain function.
