A survey by the Korea Food Service Research Institute in 2020 revealed that the use of foreign food ingredients in South Korean restaurants has significantly increased, reaching an average of 34.1% across 300 restaurants. This represents a fourfold increase from 8.3% in 2016. The survey found that seafood was the most common foreign ingredient, followed by livestock and agricultural products. The trend was most evident in processed foods like kimchi, tofu, and red pepper powder. The research highlighted that restaurant owners are incorporating more foreign ingredients to offset the cost implications of the COVID-19 pandemic and the rise in domestic food prices. This shift could potentially threaten the local agriculture and fisheries sectors.
