Proven Recipe
Vinegar water pH 3.5 (55.8%), tomato paste 3x (31.5%), sugar (10.6%), modified starch E1422 (1.16%), salt (0.63%), tara gum 175 mesh (0.21%), calcium sorbate (0.10%).
Why It Works
At just 0.21%, tara gum provides primary thickening. Stable at pH 3.5 (within 3–11 range). 175-mesh ensures rapid hydration and smooth texture.
Pseudoplastic Advantage
Flows when bottle is squeezed (high shear) but stays thick when applied to food (low shear) — the exact consumer experience expected from ketchup.
Cost Efficiency
0.21% usage level means very low cost-in-use per unit produced despite per-kg price.
