Tomato Juice, Canned, Without Salt Added: How Many Grams in a Teaspoon?
Canned tomato juice without added salt is a fully processed, strained liquid pressed from ripe tomatoes, with no sodium chloride added. Its density of 1.027 g/ml is surprisingly close to water despite tomato juice's thick, opaque appearance — the pulp is primarily water (roughly 94%) with modest amounts of citric acid, lycopene, and natural sugars contributing to the elevated density. A cup weighs approximately 243 g; a tablespoon weighs about 15.2 g. Used in Bloody Mary cocktails, tomato soups, gazpacho, and as a cooking liquid in stews and braises. The no-salt-added version is about 1–2 g per cup lighter than salted versions, because dissolved sodium chloride slightly raises density.

FAQ
- Why does tomato juice weigh almost the same as water per cup?
- Despite its thick, rich appearance, tomato juice is approximately 94% water. The tomato solids, acids, and sugars that make it flavorful are present in relatively small concentrations, contributing only about 0.027 g/ml above water density. The visible color and opacity come from lycopene pigment, which is present in very small amounts — not enough to significantly alter mass.
- How much lighter is no-salt-added tomato juice compared to regular salted tomato juice?
- Regular canned tomato juice typically contains 400–600 mg sodium per cup, from about 1–1.5 g of dissolved sodium chloride. Sodium chloride (density 2.165 g/ml) added to water raises density, so salted tomato juice may be 1–3 g per cup heavier than no-salt-added. The difference is small but measurable in precision applications.
