SPEC-03: 16-Hour 65°C Penetration Baking Curve, Aw 0.41 Crispness Index & 2×5kg Vacuum Foil Carton Spec (YF-LOTUS)
Yisheng Longzhu® Crispy Longan-Stuffed White Lotus Seeds (SKUs: YF-LOTUS-150G Retail & YF-LOTUS-10KG Bulk, License SC11735060413289) are manufactured by hand-wrapping whole core-removed Jianning white lotus seeds inside Zhangzhou 6A thick longan pulp, followed by a 16-hour 65°C closed-loop dehumidification baking cycle. Unlike vacuum-fried (VF) snacks that absorb 18%–22% oil or freeze-dried (FD) imitations that turn chalky and hollow, our 65°C thermal gradient locks water activity at Aw = 0.41 with 0.00% frying oil and an 18.5 N honeycomb crispness fracture profile.

Why Sam's Club & E-Commerce Buyers Switch from FD Freeze-Dried to 65°C Slow-Baked Longan-Lotus
Freeze-drying sublimates ice crystals out of high-sugar longan pulp, leaving a porous sponge structure that tastes like dry Styrofoam and collapses into sticky gum within minutes of opening in humid climates—driving up to 25% consumer return rates. Our 16-hour `65°C` Maillard-controlled baking caramelizes natural longan sugars around the crisp Jianning lotus seed, delivering a stable golden crunch.
