PRACTICAL WALKTHROUGH · PARAMETERS · COMMON MISTAKES
High‑concentration sucrose solutions were used to preserve food by dehydration and osmotic inhibition during the Song dynasty.
Origin: Chinese (960–1279) — Song dynasty (China)
See full technique reference →The process relies on creating a hypertonic environment that reduces water activity below 0.6, thereby suppressing microbial metabolism. Heating to 80–90 °C accelerates water loss and drives sucrose into the food matrix, forming a protective barrier. The resulting product is sweet and shelf‑stable.
