Can dried persimmons be steamed to remove their astringency

Dried persimmons can be steamed to remove their astringency. The astringency of dried persimmons is mainly due to the high content of tannins. During the steaming process, high temperatures can promote the decomposition of tannins, thereby reducing the astringency. When dried persimmons are steamed, the high temperature environment of water vapor will cause changes in the molecular structure of tannins, and some tannins will be converted into soluble substances, reducing the astringency. It is advisable to control the steaming time at 10-15 minutes. If it is too short, the astringency may not be completely removed, while if it is too long, it will affect the taste. After steaming, it should be spread out and dried in a timely manner to avoid mold growth caused by residual moisture. For varieties with high tannin content, steaming can be repeated 1-2 times to enhance the effect, but attention should be paid to maintaining the integrity of dried persimmons. If dried persimmons have residual astringency due to incomplete astringency or improper storage, steaming may not completely remove the astringency. This type of situation is often related to the variety, maturity, or processing technology of persimmons. For example, some wild persimmons have extremely high tannin content and are difficult to completely decompose through conventional steaming. At this point, dried persimmons can be stored in a sealed container with ethylene releasing fruits such as apples and bananas, utilizing their natural ripening effect to further reduce tannin content.

For daily consumption of dried persimmons, it is recommended to choose fully de astringent products. When making, it is necessary to ensure that the persimmons meet the maturity standards and undergo air drying to remove astringency. Steamed dried persimmons can be paired with nuts and yogurt to alleviate the irritation of tannins on the gastrointestinal tract and enhance their nutritional value. People with weak gastrointestinal function should control their food intake, avoid eating on an empty stomach, and prevent discomfort caused by the combination of tannins and stomach acid.
