　　1. External Sensory Characteristics: Dexing raspberries are aggregate fruits formed by the fusion of many small drupelets, taking on a conical or flattened conical shape, 0.8–1.5 cm in height and 0.6–1.4 cm in diameter, with relatively large individual fruits. The surface is gray-green with grayish-white fuzz, bluntly rounded at the top and indented at the base center. The persistent calyx is brownish, with a fruit stalk scar but no leaf stalk. The small fruits are easily detachable, each being crescent-shaped, densely covered with grayish-white fuzz on the back, with distinct reticulated patterns on the sides and raised ridges on the belly. They are lightweight and hard in texture, with a faint aroma and mildly sour and astringent taste. Dexing raspberries are characterized by their large size, plumpness, whole and firm berries. 2. Internal Quality Indicators: Dexing raspberries have high edible and medicinal value, rich in glucose, fructose, VC, VE, 17 types of amino acids, total flavonoids, minerals, and other components. The edible rate of Dexing raspberries is 97–99%, with 7.16–8.50 g of amino acids per 100 g (including 2.27–2.83 g of 7 essential human amino acids). A comparison table of internal quality indicators between Dexing raspberries and other raspberries is shown in the table below (omitted). Notes: ① Items 1–7 in the table above are essential human amino acids; ② The characteristic indicator data for Dexing raspberries are measured values; ③ Data for other raspberries refer to the “Overview of Research on the Development and Utilization of Rubus palmatus.” 3. Safety Requirements: Standards such as GB14881-94 General Hygienic Specifications for Food Enterprises are applied to raw material intake, in-process control, finished product acceptance, and sanitary operation inspections.
