Seven-Colored Potato

The Seven-Colored Potato is a geographical indication certification trademark.

　　The "Seven-Colored Potato" from Huili is a distinctive organic green agricultural product of Huili County, commonly known as "Little Black Potato." It is grown in high-altitude cold regions at elevations above 2,000 meters, where there is abundant sunlight, fresh air, pure water, and a cool climate. The soil in the designated planting areas contains 1.9%–4.3% organic matter. During the cultivation process, cattle and sheep manure is used along with compost made from the branches and leaves of plants such as Huashan Pine and Yunnan Pine. These favorable conditions contribute to the unique and superior quality of the "Huili Seven-Colored Potato." This variety is small in size, typically with a diameter of 3–6 cm. When cut, about 5 mm beneath the skin, there is a ring-shaped layer of purple flesh that is vibrant in color and rich in nutrients. It tastes excellent when eaten fresh and has a distinctive flavor. In addition to containing the starch, protein, various trace elements, and small amounts of fat found in regular potatoes, these potatoes also boast a rich natural pigment—anthocyanin. Anthocyanins help inhibit carcinogens, act as antioxidants, combat aging, enhance blood vessel elasticity, improve circulatory system function and skin smoothness, reduce inflammation and allergies, increase joint flexibility, and offer higher nutritional value than ordinary potatoes. As a result, they are widely loved by consumers. They were once awarded the "Highly Popular Exhibition Prize" at the 2010 Western China International Agricultural Products Trade Fair.

　　　The "Huili Seven-Colored Potato" is rich in nutrition and has a unique flavor, making it a flagship agricultural product of Huili County. In 2010, the county’s Party Committee and government decided to establish a premium brand to vigorously develop the Seven-Colored Potato industry and maintain or enhance its reputation both within and outside the province. A leadership group was formed to register the "Huili County Seven-Colored Potato" geographical indication certification trademark. The group was dedicated to building the "Huili Seven-Colored Potato" brand and providing services related to the development, management, technical consultation, and technical guidance of Huili’s specialty agricultural products. Under the leadership of the registration leadership group for the "Huili Seven-Colored Potato" geographical indication certification trademark, and with close cooperation from relevant departments, the Huili Specialty Agricultural Products Development Management Center spent nearly two years of effort. On December 28, 2011, the "Huili Seven-Colored Potato" geographical indication certification trademark was officially approved by the Trademark Office of the State Administration for Industry and Commerce of the People’s Republic of China, and the certification trademark certificate was issued in February 2012.
