Black rice is a kind of rice with both medicine and food. The content of vitamins, trace elements and amino acids (amino acid foods) is higher than ordinary rice. Studies have shown that the darker the color of rice, the more effective the anti-aging (anti-aging food) effect of epidermal pigments, of course, the role of black rice pigment is the strongest in all colors of rice. In addition, this pigment is also rich in flavonoid active substances, which is five times as much as white rice and has a great effect on preventing arteriosclerosis. In addition, black rice contains more dietary fiber, starch digestion is slow, the blood glucose (blood sugar food) index is 55 (white rice is 87), and potassium, magnesium, and other minerals in black rice also help control blood pressure (blood pressure food) Reduce the risk of cardiovascular and cerebrovascular diseases. Therefore, patients with diabetes (diabetic foods) and patients with cardiovascular diseases can use black rice as part of their diet. White particles, polyethylene glycol butyl diacid butyl ester (PBS) by succinic acid and butyl glycol by condensation polymerization of synthetic, resin in milky white, odorless, vulnerable to a variety of microorganisms or plants and animals in nature of the enzyme catabolism, eventually decomposed into carbon dioxide and water, is typical of completely biodegradable polymer material has good biological compatibility and biological absorbability;Density of 1.26 g/cm3, melting point 114, according to the high or low molecular weight and molecular weight distribution, crystallinity between 30 ~ 45% in the 1990 s it into the material research field, and quickly became can be widely applied in the universal one of research hotspots of biodegradable plastic materials, heat resistant performance is good, heat distortion temperature, and the products using the temperature can exceed 100 synthetic raw material sources can be either its oil resources, also can through fermentation by biological resources, PBS are outstanding in biodegradable plastic materials.

At present, there are two common cases of black rice adulteration in the market, one is the storage of inferior or inferior black rice for a long period of time, after the dyeing, the second is sold well; the other is the use of plain rice dyed and posing as Black rice is for sale. Consumers can purchase black rice from the following aspects: First, look at the color and appearance of black rice. Generally, the black rice is glossy, and the rice grains are even in size. There are few broken rice, low waist (cracks on rice grains), no insects, and no impurities. The color of inferior and inferior black rice is dark, the grain size is uneven, the plumpness is poor, broken rice is more, there are insects, there is agglomeration. For dyed black rice, since the black color of black rice is concentrated in the cortex, the endosperm is still white. Therefore, consumers can scrape off the outer skin layer of rice and observe whether the rice grain is white. If it is white, it is highly likely to be artificially stained. black rice.
