Description

Method for preparation of fermented dried persimmon using enzyme {Method for preparation of matured dried persimmon using enzyme}

The present invention relates to a method for producing fermented dried persimmon using an enzyme, and more particularly, by fermenting a fermented enzyme to a surface of dried persimmon dried by peeling the peeled raw persimmon and fermenting for a certain period of time, then aging. It relates to a method for producing fermented dried persimmon using an enzyme.

In general, dried persimmon is one of the fruits used during holidays and sacrifices, and can be stored for a long time.

The method of making dried persimmons, according to the book, is to pick ripe hard water in August and peel off the peels, remove the faucet and spread it on a large wooden board to avoid rain. When the stomach is black and dry, it turns over, and when it dries, it turns over again and dry.

When it is dry and flat, make a good shape and put it in a large, dry jar. Dry the persimmons together and leave them on top to cover them. It is then known to taste better if it is covered with good straw and then taken out after installation (雪: white powder on dried persimmon).

In the production of large scale dried persimmon sulfur fumigation (硫黃 燻蒸: steamed by steaming steam.) To improve the quality. This fumigation peeled persimmon with sulfur for 30 to 40 minutes to sunshine well. It is then transferred to a well-ventilated drying room and dried at 30-38 ℃ for 4-5 days.

When the persimmons turn yellowish brown and the outer shell starts to harden, the flesh is rubbed with your hands to soften, the seeds are removed, and the holes are combined to form a dry shape. After three weeks, the weight of dried persimmon is about 75% of the weight of raw persimmon, and when you press it with your finger, the pulp enters and is returned to its original shape.

Put dried straw in a box and put dried persimmon and put it in a cool place so that the surface of dried persimmon is covered with white sugar powder. When peeling persimmons, a knife made of iron reacts with the tannins in the persimmon to change its color, so a stainless steel knife is recommended.

Persimmons are narrower than dry weight, so avoid sudden drying. If you dry too much, the pulp hardens, and if the drying is insufficient, it is easy to form mold, so be very careful. The composition of dried persimmon is 32% water, 6.3% protein, 0.44% fat, 44.8% carbohydrate, 15% fiber, and 1.99% ash.
