Description
Kaixin Li, with four colleagues, details a 2026 study of sprays that slow colour change in persimmon fruit. Growers treat astringent persimmons with carbon dioxide to remove the harsh taste, yet the cure speeds ripening and peel colour shift. A spray called 1-MCP, used before harvest, blocks the ripening signal ethylene.
Three groups were compared: untreated fruit, carbon-dioxide-treated fruit, and sprayed fruit then treated with gas. The gas alone raised breath rate, ethylene output, peel colour score, and orange pigment levels, while green pigment fell. Sprayed fruit kept more green pigment and scored lower on the rest. Gene tests showed the gas switched on colour-building genes up to about twenty fold, while the spray held many of them near flat. The spray thus delays the colour shift the gas brings.
