65°C 16-Hour Slow-Baked Crispy Longan-Stuffed Lotus Seed vs Freeze-Dried (FD) Fruit vs Vacuum-Fried (VF) Chips
YONG FOOD's Yisheng Longzhu® (Crispy Slow-Baked Longan-Stuffed White Lotus Seed) uses a proprietary 16-hour 65°C low-temperature staged dehumidification baking curve rather than freeze-drying (FD) or vacuum-frying (VF). While FD fruit is porous, chalky, and turns sticky within 8 minutes of opening in 65% RH humidity, and VF chips absorb 18–25% frying oil, our 65°C slow-baked longan pulp forms a dense caramelised micro-crust (Aw = 0.41, 0% frying oil) that stays crispy for 4+ hours on a tea-house saucer.

Maillard Caramelisation Without Acrylamide or Nutrient Destruction
By maintaining chamber temperature strictly at 65°C ± 1.5°C across 16 hours, longan polysaccharides undergo gentle caramelisation around the Jianning white lotus seed without triggering high-temperature acrylamide formation.
Frequently Asked B2B Procurement & Formulation Questions
Q: Why do tea-house chains prefer 65°C slow-baked longan-lotus over freeze-dried fruit?
Verified Factory Answer: Tea ceremony tables have steam from boiling kettles. Freeze-dried fruit shrivels and sticks to teeth around tea steam, whereas our 65°C slow-baked longan pearls stay crisp throughout a 2-hour tea session.
