Introduction to blackcurrant The ripe fruit of blackcurrant is a small black berry, which is rich in vitamin C and anthocyanins and can be eaten. It can also be processed into fruit juice, jam, canned food, beverage and other foods. Blackcurrant is rich in vitamin C, phosphorus, magnesium, potassium, calcium, anthocyanins and phenols. At present, it is known that blackcurrant can prevent gout, anemia, edema, arthritis, rheumatism, oral and throat diseases and cough, and has good effects on cardiovascular and cerebrovascular diseases, hypertension and hyperlipidemia.
The nutritional value of blackcurrant is 1. Blackcurrants are rich in protein and carbohydrates. Among the total carbohydrates, glucose accounts for 43% and fructose accounts for 57%. Glucose can directly supply energy to human body, while fructose can not only supply energy, but also inhibit the consumption of protein in the body, which can be used as a nutritional supplement for athletes and manual workers.
2. The pigment content in blackcurrant is very rich, reaching 4.53%. Blackcurrant pigment is a water-soluble natural pigment, which belongs to anthocyanins and has strong coloring power. The main components are anthocyanin -3- glucoside, anthocyanin -3- rutin, delphinidin -3- glucoside and delphinidin -3- rutin. Anthocyanin can inhibit and hinder platelet coagulation caused by collagen, arachidonic acid, epinephrine and adenosine triphosphate, thus preventing thrombosis and arteriosclerosis caused by intravascular platelet coagulation. The total phenol content of blackcurrant juice reached 2863mg/ 100g, and its antioxidant capacity reached 27.86 teac mol/ 100g, which endowed it with the functions of scavenging free radicals and delaying aging.
Blackcurrant is rich in organic acids, especially citric acid. These organic acids, such as citric acid, can not only expel lactic acid accumulated in blood, but also inhibit the production of new lactic acid, thus achieving the effect of cleaning blood. In addition, they also have the functions of stimulating appetite, restoring physical strength, relieving fatigue, improving constipation, calming the nerves and eliminating troubles.
The efficacy of blackcurrant Blackcurrant is not only a delicious and nutritious fruit, but also has many health-preserving effects, such as strengthening gums, protecting liver, improving visual function, enriching blood and benefiting qi, and resisting aging.
In addition, the content of zinc in blackcurrant seeds is high, which can be used as a source of zinc supplementation. The content of vitamin C is extremely high, obviously higher than that of citrus and hawthorn, and the content of linoleic acid in seeds is high, which has the functions of lowering blood pressure, reducing blood lipid and resisting arteriosclerosis. Another kind of γ -linolenic acid, which is a unique component that cannot be synthesized by human body, can play an anti-cardiovascular role. Polyunsaturated fatty acids also have a good protective effect on cardiovascular and cerebrovascular diseases, and blackcurrant leaf extract is very beneficial to prevent osteoarthritis.
