Rice is a key staple food for Koreans, but its consumption has been on a steady decline in recent decades due mainly to changes in diet and eating habits. South Korea has been making efforts to foster its rice-processing businesses to increase the demand and exports.
On the back of such efforts, the country's consumption of rice for processed goods reached 568,000 tons in 2018, rising 5.6 percent on average over the past five years.
The local market for processed rice products was estimated at 5.3 trillion won ($4.57 billion) in 2018, the ministry said. (Yonhap)
