South Korea's citron production is projected to decrease by over 20% due to cold weather damage, potentially disrupting the export of citron processed foods. Despite this, the industry has seen a 5% increase in export volume from January to October this year, thanks to new markets and expanded opportunities in the US. Whole Foods has highlighted citron as a rising food trend for 2022. However, export challenges are anticipated due to high costs and the need to maintain competitiveness in the market.
