The Inception of ‘Potato-Turned Rice’
In a remarkable stride toward food security, Yunnan Province in southwest China has launched the first production and marketing trials of ‘potato-turned rice.’ This rice-shaped starch product is made from potatoes using a novel extrusion recombination technology developed by Wu Qi, a prominent polymer physical chemist and academician of the Chinese Academy of Sciences. After more than five years of rigorous research and development, the production line in Qiaojia County began operating in November 2024.
The Technology Behind the Transformation
The innovation lies in reshaping the potato starch chains to mimic the texture and properties of rice. Potato starch, naturally more branched than rice starch, undergoes a process involving polymer extrusion, granulation, and food macromolecule processing. These techniques improve the texture and shelf life of the final product, making it more palatable and convenient for consumers. Unlike conventional rice, ‘potato-turned rice’ requires no washing or soaking and cooks faster, using less water.
Economic and Agricultural Impact
Initial estimates suggest that 2.5 tonnes of potatoes can produce 1 tonne of ‘potato-turned rice,’ increasing the output value by over ten times. The production line is projected to process approximately 2,500 tonnes of fresh potatoes annually, yielding 1,000 tonnes of ‘potato-turned rice’ with an output value of about 30 million yuan. This innovation not only provides a solution for the short shelf life of fresh potatoes but also enhances their economic value.
Market Reception and Potential
The first batch of ‘potato-turned rice’ has already hit the local market, receiving positive feedback, particularly from middle-aged and elderly consumers. The product’s extended shelf life and lower storage costs make it an attractive alternative to traditional staples. By reducing the need for ventilation and climate control during storage, this innovation addresses logistical challenges and cost inefficiencies.
A Step Toward Food Security
Potatoes, known for their adaptability and high yields, have long been an essential crop in China. By transforming them into a staple food with broader appeal and practicality, ‘potato-turned rice’ has the potential to diversify dietary options and bolster food security. The ongoing trials and technological advancements signal a promising future for this innovative product in both domestic and international markets.
