What is the nutritional value of Yushu black barley

The protein and fat content of black barley are 11.59% and 3.63%, respectively, while the moisture and ash content are 11.96% and 2.04%, respectively, which is not significantly different from that of white barley. The total dietary fiber content of black barley is 16.39%, mainly insoluble dietary fiber, up to 14.03%. Although lower than that of white barley, it is much higher than other crops. According to GB28050-2011 "National Food Safety Standard General Principles for Pre packaged Food Nutrition Labeling", a dietary fiber content greater than 6 g/100 g is considered high or rich in dietary fiber or a good source. Therefore, black barley can be called a cereal crop rich in dietary fiber
