Persimmon off the astringent six methods

To reduce the astringency in persimmon fruits, it's essential to convert the soluble tannins into an insoluble form. This process makes the fruit more pleasant to eat and removes that dry, bitter feeling. There are several effective methods for removing astringency from astringent persimmon varieties. One common method is the **warm water technique**. The persimmons are placed in a large insulated container covered with straw curtains to retain heat. They are then submerged in warm water around 40°C and kept at this temperature for 10 to 24 hours. This method helps preserve the fruit’s original texture, making it firm and crisp, while also maintaining its bright color. Another popular approach is the **lime water method**. Here, the harvested persimmons are soaked in freshly prepared lime water (4% concentration using quicklime). This process usually takes about 2 to 3 days and results in a crisp, flavorful fruit without the astringent taste. The **fruit ripening method** involves placing persimmons together with apples or pears in a sealed container. The natural gases released by the ripe fruits—such as ethylene and carbon dioxide—help accelerate the ripening of the persimmons. After 3 to 5 days, the persimmons become soft and lose their astringency, while also developing a brighter color and better flavor. The **etephol method** uses a 0.25‰ ethephon solution. This can be sprayed directly onto ripe persimmons before harvest or applied by immersing harvested fruit in the solution for 3 minutes. After 3 to 7 days, the astringency disappears, and the fruit becomes softer and more palatable. The **carbon dioxide method** is another efficient way to remove astringency. Persimmons are placed in a sealed container, and carbon dioxide gas is injected at a concentration of about 70%. If the container has a pressure gauge, the pressure can be adjusted to 0.7 to 1.2 kg/cm². At a temperature between 15°C and 25°C, the astringency is removed within 2 to 3 days. This method preserves the fruit's firmness and makes it easier to store and transport. Lastly, the **alcohol method** involves placing the persimmons in a closed container and spraying each layer with 35% alcohol or white wine, preferably mixed with a small amount of acetic acid. The container is then sealed and left at 18 to 20°C for 5 to 6 days. This technique effectively removes the astringency while keeping the fruit's quality intact. Each of these methods offers unique benefits depending on the desired outcome, storage conditions, and availability of resources. Whether you're a grower or a home user, choosing the right technique can significantly improve the eating experience of astringent persimmons.
