Group 1 - The white frost on persimmons, known as "persimmon frost," is a natural crystallization of nutrients that occurs during the drying process and is safe to eat [2][3] - The thickness of the frost does not necessarily correlate with the quality of the persimmon; it is influenced by sugar content and processing methods [3] - The national standard for persimmons specifies a moisture content of no more than 35% and a total sugar content of at least 60%, emphasizing that quality is determined by both raw materials and processing [3] Group 2 - Consumers can select high-quality persimmons by observing the frost layer, fruit color, texture, and smell [4] - High-quality persimmon frost should be fine and uniform, while artificial frost appears rough and easily falls off [5] - The fruit should have a consistent amber or deep orange color without any unusual spots, indicating potential dyeing or spoilage [6] Group 3 - Quality persimmons should have a firm yet slightly springy texture; overly hard or soft persimmons may indicate improper drying or excess moisture [7] - Fresh persimmons should emit a natural sweet aroma; any sour, alcoholic, or moldy smell indicates spoilage [8] - Consumers should avoid overeating, especially those with diabetes, and should not consume persimmons on an empty stomach to prevent gastrointestinal issues [9][10]
