Removing Persimmon Astringency: From Dung Smoke to Ethylene Gas

Unripe persimmons are astringent due to tannins. Curing methods include:

Traditional: smoke from burning dung, sake fumes, lime water, CO2 chambers.
Modern: ethylene gas (3 days), ethephon dip, alcohol-needle puncture + straw box.
Home: bag with ripe bananas/apples (2-4 days).
India: paper-wrapped with pears (3 days).

Non-astringent cultivars need no curing.
