Yellow River Estuary Rice

Yellow River Estuary Rice

Yellow River Estuary Rice is a product with geographical indication.

　　Yellow River Estuary Rice is produced in the Yellow River Delta region, particularly in Kenli County, Dongying City, Shandong Province. The rice is renowned for its uniform grains, crystal-clear appearance, moderate stickiness, sweet and delicious taste, and rich nutrition, making it a premium variety among rice types. Fondly referred to as "Yellow River Estuary Rice," it enjoys strong market demand and consumer popularity.

　　The silt carried by the Yellow River is rich in various chemical elements such as nitrogen, phosphorus, and potassium, as well as abundant organic matter. The Yellow River Delta area has a temperate continental climate with ample sunlight and large diurnal temperature variations. The annual rainfall is around 600 millimeters, mostly concentrated during the critical period of rice panicle development. Additionally, the newly deposited land in the Yellow River Estuary contains a small amount of salinity and alkali, all of which contribute to the superior quality of Yellow River Estuary Rice. The rice also benefits from a long growth period (160–180 days), unique climatic conditions, the use of high-quality japonica rice varieties, and irrigation with Yellow River water. These factors give the rice its distinctive qualities: it is crystal-clear, has a long viscous texture, is elastic and firm without being sticky, and boasts a mellow and fragrant aroma. The rice has minimal chalkiness, with plump and glossy grains, and offers special nutritional benefits: high protein content (≥11.6%), more than six types of amino acids, and an abundance of beneficial trace elements for the human body such as iron, zinc, iodine, selenium, potassium, and calcium.

　　Whether steamed or boiled, Yellow River Estuary Rice is fragrant and delicious. As early as the 1980s and 1990s, it had already earned a reputation in Beijing and Tianjin, making it a top-grade variety of japonica rice. Due to specific climatic limitations, Yellow River Estuary Rice is only produced in the northernmost part of the Yellow River Delta, with an annual planting area of about 200,000 mu and a total output of over 80,000 tons. After review by the Provincial Pollution-Free Agricultural Products Label Approval Committee, Kenli County’s “Yellow River Estuary Rice” was approved to use the national pollution-free label. Kenli County, located at the mouth of the Yellow River, has over 700,000 mu of saline-alkali wasteland. After years of development, the county now has 120,000 mu of rice cultivation area, with an annual output of 48 million kilograms. Thanks to ample sunlight, long growth periods, and minimal pest and disease occurrence, “Yellow River Estuary Rice” features translucent texture and good gloss. In 1990, it was certified as a “pollution-free food” by the World Health Organization and appeared on the dining tables of athletes during the 11th Asian Games.
