In 2011, the Michelin Green Guide Taiwan featured 14 "must-try" Taiwanese delicacies, with papaya milk earning a coveted spot. The star ingredient—papaya—has only been enjoyed as fruit by Taiwanese for about 60 years.

According to agricultural media The News & Market, papaya milk's origins blend chance with inevitability: chance in timing (when both ingredients were abundant), inevitability in policy (government milk promotion campaigns). Ice shops began serving it in the 1960s, possibly originating in Taichung City or Kaohsiung City—the exact birthplace remains unclear. "Kaohsiung Milk King" cleverly claimed the brand name first.

Export Success to Japan, Greenhouse Cultivation Ensures Stable Production

Papaya arrived in Taiwan from China during the late Qing Dynasty in its original, strongly-flavored form, primarily used as animal feed. It wasn't until 1954, when the Fengshan branch of the Agricultural Research Institute introduced Solo No. 1 and Risheng varieties for breeding, that Taiwanese began eating papaya as fruit. Today's market leader, the sweet and tender "Tainung No. 2" papaya, descends from the Risheng variety, with Tainan serving as the largest production region.

In 1975, Taiwan successfully exported papaya to Japan. To prevent papaya ringspot virus infections, growers have increasingly relied on greenhouse cultivation, stabilizing yields. While papaya produces year-round, peak season runs from June to October. The sweetest, most flavorful fruit comes from October to November harvests, when autumn's dramatic day-night temperature swings boost photosynthesis during the day, allowing sugars to concentrate.

Beyond fresh consumption, papaya can be pickled or dried into preserved fruits and snacks. The flesh is rich in sugars, pectin, vitamins, organic acids, and papain, while the seeds contain glucosinolates, tocopherols, and carotenoids—antioxidant compounds increasingly recognized as promising ingredients for functional food products.
