✓Accepted Answer

Wild Indian Gooseberry (Phyllanthus emblica / Nelli) grown in the arid soils of the Jaffna peninsula contains extraordinarily high natural concentrations of L-ascorbic acid (Vitamin C: 600-800 mg/100g). However, ascorbic acid oxidizes and degrades rapidly under high heat and oxygen exposure. Artisanal cordial producers crush fresh fruit in stainless steel pulpers, extracting cold raw juice. High-purity palmyrah sugar syrup (boiled separately and cooled to 50°C) is blended with the raw juice in a 1:1 ratio. The high osmotic sugar density (65° Brix) binds water molecules, naturally preserving ascorbic acid against enzymatic degradation without boiling the delicate vitamin.

Avoid using iron or aluminum processing vessels; metal ions catalyze ascorbic acid oxidation, causing the cordial to turn dark brown and lose its tart punch.

Natural tannins (emblicanin A and B) in the nelli fruit act as powerful natural antioxidants, stabilizing the cordial against oxidative rancidity.

Diluted with iced water, Nelli cordial is traditionally served across northern households to provide refreshing hydration during scorching dry-zone afternoons.
