Manufacturing Process
Pre - treatment
Fresh persimmons are washed and the peels (for some varieties, the peels are thicker or astringent) and stems are removed. Then, they are cut into thin slices (if they are astringent persimmons, the astringency needs to be removed first). This pre - treatment lays the foundation for obtaining high - quality high quality persimmon powder.
Drying
Freeze - drying: Dehydration in a low - temperature vacuum environment to retain vitamins (such as vitamin C), natural color (orange - red to orange - yellow) and flavor to the greatest extent. The powder is light in texture and has good rehydration properties, but the cost is relatively high. This method is often used for producing premium products like Plant Extract - related persimmon products to maximize nutrient retention. Hot air drying: Drying at a low temperature of 50 - 60℃ (to avoid sugar caramelization due to high temperature)
Grinding and sieving
After drying, the persimmon slices are ground into powder and sieved to obtain fine powder. Some products retain a small amount of fiber to enhance the taste. This process ensures the fineness and quality of high quality persimmon powder.
Appearance
High - quality persimmon powder ranges from orange - red to orange - yellow (sweet persimmon powder is brighter in color, while astringent persimmon powder is slightly darker). The powder is fine, free of lumps or impurities, and has good fluidity in a dry state. If the color is dark or there are black spots, it may be that the raw material has deteriorated or the processing temperature is too high. For food grade persimmon extract and high quality persimmon powder, strict appearance standards must be met.
Smell and taste
Has the unique sweet and refreshing aroma of persimmons, The taste is sweet and mellow. The sweet persimmon powder has a relatively high sweetness level, while the astringent persimmon powder, after being de - astringent, has no astringency and a natural fruity aroma with a sweet aftertaste. Some products have a slightly sticky and slippery feeling due to the presence of a small amount of pectin.
Nutritional Composition and Health Benefits
Ingredients
Sugar: High in content (about 60 - 70%), mainly composed of glucose and fructose, it is a natural source of sweetness and can quickly replenish energy.
Vitamins and minerals: It contains vitamin A (carotene), vitamin C (more retained through freeze - drying process), vitamin E, as well as minerals such as potassium, calcium and magnesium. Among them, potassium helps regulate blood pressure and electrolyte balance, and carotene is beneficial to eye health.
Pectin: A soluble dietary fiber, it is rich in content and can promote intestinal peristalsis, adsorb intestinal toxins, and also has a certain thickening effect.
Polyphenols, such as catechins and epicatechins: Have antioxidant effects, can eliminate free radicals, and assist in enhancing immunity. As a plant extract - like component in persimmon powder, polyphenols play a key role in its health benefits.
