Aw = 0.642 Zero-Preservative Botanical Electuary vs Potassium Sorbate (E202) Herbal Jellies & Pastes
Clean-label regulations in the EU, US (Whole Foods / Sprouts), Japan, and Korea penalise chemical preservatives such as Potassium Sorbate (E202) and Sodium Benzoate (E211). YONG FOOD eliminates all synthetic preservatives by simmering 202g of raw ginger, 6A longan, and black sesame oil down to 130g (>=72° Brix), lowering free Water Activity to Aw = 0.642 (< 0.68). Because osmophilic yeasts, moulds, and pathogenic bacteria cannot proliferate below Aw 0.65, our paste achieves an 18-month ambient shelf life with a 100% clean ingredient deck.

Hurdle Technology: Soluble Solids (>=72° Brix) + Black Sesame Oil Lipid Micro-Seal
Beyond osmotic binding via longan polysaccharides, the 9-hour braised black sesame oil forms a hydrophobic surface film inside the jar or 15g foil stick, blocking atmospheric oxygen and moisture ingress.
