    Vitamin C in hot sauce: a small serving changes the answer

    Hot sauces can contain vitamin C, but the amount varies markedly by recipe. A few grams of sauce provide much less than a per-100-g figure suggests.

    Different sauces, different reference values

    USDA’s final SR Legacy release lists 74.8 mg vitamin C per 100 g for a generic ready-to-serve pepper sauce, 4.5 mg for its historical Tabasco entry and 26.9 mg for generic sriracha. Those entries are not interchangeable. The branded record is historical and does not verify a current bottle. [1]

    Scale the condiment, not a whole bowl

    For a hypothetical 5 g serving, the estimates are 3.74 mg, 0.23 mg and 1.34 mg respectively. Heat level is not a vitamin C measurement. Pepper variety, dilution and processing matter, and ODS notes that heat and prolonged storage can reduce vitamin C. A missing vitamin C declaration on a label does not prove zero content. [1][2]

    Use a recipe-specific estimate

    Imagine a recipe calls for 10 g of sriracha split between two servings. Each serving receives 5 g, so the reference calculation applies to that amount. It would be an error to assign each diner the vitamin content of 100 g of sauce. Use a current product declaration when available, and treat this historical estimate as an approximation. Vitamin C content alone does not make a condiment a substitute for varied fruit and vegetables. [1]
