5. Expert advice
Professor Li from the Watermelon Research Institute of the Chinese Academy of Agricultural Sciences pointed out: "Affected by the climate in 2024, it is recommended that consumers give priority to watermelons in the production areas north of the Yellow River. The temperature difference between day and night during the formation period of the pulp is more than 12°C, and the sugar content is more fully precipitated." At the same time, he reminded that watermelons should not be refrigerated for more than 48 hours, otherwise the pulp structure will be destroyed.
