(The data were obtained from fresh fruit of Hull and Chester, the widely marketed varieties; The data is only an average value, and there are errors above and below, which mainly change with the changes of cultivation, environment and other conditions. For more details, see the Nutritional Content of Fresh Blackberry Fruits and Processed Products. The content of sugar, vitamin C, vitamin B1 and vitamin B2 in fresh fruit of Blackberry is comparable to that of other fruit trees, and the content of organic acid, crude protein, vitamin K and amino acid is higher than that of other cultivated fruit trees. It is found that the content of vitamin E is the highest among all cultivated, wild and semi-wild fruit trees, while the content of selenium is rare in fruit trees. A total of 18 kinds of amino acids, 8 kinds of essential amino acids, and high content, but also rich in γ-aminobutyric acid. They also had higher levels of six essential mineral elements (potassium, calcium, sodium, magnesium, zinc, iron and phosphorus). Among them, vitamin K can promote the liver synthesis of coagulation substances, to promote blood coagulation has a good effect; Vitamin E protects the integrity of cells and their internal structures, prevents the destruction of certain enzymes and internal components of cells, and delays aging; Selenium can resist oxidation, prevent aging, improve immunity, together with vitamin E to antagonize the protective agent of toxic substances; γ-aminobutyric acid, as a nerve conduction substance, has the role of promoting brain metabolism, lowering blood pressure, lowering blood lipids and anti-arrhythmia.
