Nutrition by serving

Sainsbury's Bolognese Pasta Sauce contains 41 kcal, 0.5g of fat (0.1g saturated), 7.1g of carbohydrate (5.5g sugar), 1.4g of protein and 0.62g of salt per 100g.

Sainsbury's own-brand Bolognese Pasta Sauce is nutritionally very close to Tesco's equivalent — the differences per 100g amount to fractions of a gram across all nutrients. This reflects the highly standardised nature of the own-brand tomato pasta sauce category across UK supermarkets.

NOVA food processing classification

Sainsbury's Bolognese Pasta Sauce is classified as NOVA 4 — ultra-processed food under the NOVA food processing system.

The following industrial additives are present in its ingredient list: modified maize starch, thickener. These ingredients are not present in a home-made equivalent of this sauce — they are used to achieve a consistent texture, extended shelf life, and flavour stability at industrial scale.

NOVA 4 classification does not automatically mean a food is harmful. The NHS Eatwell Guide does not use NOVA classifications, and processed convenience foods can form part of a balanced diet. The significance of the NOVA classification is that it gives a shorthand for identifying foods that have been engineered rather than cooked — useful context when evaluating the ingredient list alongside the nutrition numbers.

Supermarket own-brand pasta sauces are almost universally NOVA 4 — the modified maize starch and citric acid present in this sauce appear across virtually all ambient pasta sauces regardless of brand or price point. The NOVA classification is determined by the formulation of the product, not by its retail price or own-brand status.

Salt

Sainsbury's Bolognese Pasta Sauce contains 0.62g of salt per 100g. A quarter-jar serving (88g) delivers 0.55g of salt, 9% of the adult daily limit of 6g.

The 2010 FSA voluntary salt reduction target for pasta sauce is 1.1g per 100g. At 0.62g per 100g, this product meets that target.

Sugar and added sugar

Sainsbury's Bolognese Pasta Sauce contains 5.5g of sugar per 100g. A quarter-jar serving (88g) delivers 4.84g of sugar. Tomatoes contain natural sugar (fructose), so some sugar content in any tomato-based sauce is expected. The key question is whether additional sugar has been added beyond what the tomatoes themselves provide.

The ingredient list for Sainsbury's Bolognese Pasta Sauce includes added sugar. Tomatoes at peak ripeness contain around 2.5g to 3g of natural sugar per 100g — any total sugar content meaningfully above that reflects added sugar in the recipe. The amount of added sugar is not required to be declared separately on UK food labels, making it impossible to determine from the nutrition panel alone how much of the stated sugar is natural versus added.
