Shangzhi Red Raspberries are an agricultural geographical indication product.

　　Red raspberries, commonly known as "marlin" or "trays," are plants of the genus Rubus in the Rosaceae family and are internationally recognized as "third-generation fruits." Rich in nutrients, red raspberries contain various easily absorbable elements. They consist of 8% fructose, 2.3% organic acids, and over 1% amino acids; every 100 grams of fresh fruit contains 62 mg of vitamin C, 750 mg of vitamin P, 1.4 mg of vitamin E, 1.4 mg of carotene, 281 mg of potassium, 113 mg of phosphorus, 36 mg of calcium, 29 mg of magnesium, 4 mg of iron, 2.5 mg of salicylic acid; they also contain the anti-aging substance superoxide dismutase (SOD) and the anticancer substance ellagic acid. The levels of superoxide dismutase and ellagic acid in these raspberries are higher than those found in any existing cultivated or wild fruits.

　　In recent years, Shangzhi City has promoted the development of the red raspberry industry. With a cultivation area of 17,300 mu, it has become the county or city with the largest red raspberry planting area in China and has been named the "Hometown of Chinese Red Raspberries" by the China Economic Forestry Association.

　　In 2010, the city’s berry planting area reached 75,000 mu, with a total output of nearly 16,000 tons. Among them, red raspberry production was 9,133.5 tons, blackcurrant production was 4,028 tons, and strawberry production was 1,820 tons. The city had a total of 12 berry processing enterprises, processing 5,300 tons of berries. This year, the city will further strengthen its "red economy" centered on red raspberries. It plans to develop and renew 5,000 mu of berries, bringing the harvesting area to 35,000 mu. The number of berry processing enterprises will increase to 13, with a purchasing and processing volume of 9,000 tons. The total industrial output value is expected to reach 350 million yuan, creating employment for 20,000 workers.
