Taiwan's Custard Apple export amounts to 14,355 MT, valued at 4 million USD. In 2019, 90% of the exports went to China, due to the bottleneck in preservation technology.
After 5 years of research and development, new freezing technology processes Custard Apple at -40C, which is in compliance with Japan and South Korea's regulation as frozen food. The shelf life has also extended to 2 months. With the new technology and new buyers from Japan and South Korea, custard apple's estimated market value will grow by 10% compared to 2019.
