Why is fruit yogurt denser than whole milk despite being low-fat?

Removing fat (which is less dense than water at ~0.91 g/ml) and adding fruit solids (sugars, pectin, fiber -- all denser than water) both push the density upward. The bacterial fermentation also concentrates milk proteins. The net result is 1.036 g/ml compared to 1.031 g/ml for whole milk, a small but consistent difference that adds about 1 g per cup.

Can I substitute fruit yogurt for sour cream in baking by volume?

Not precisely by volume, because sour cream (~1.013 g/ml, ~240 g/cup) is lighter per cup than this yogurt (1.036 g/ml, ~245 g/cup). A cup of yogurt delivers about 5 g more mass. Additionally, yogurt has higher acidity and lower fat than sour cream, which affects both leavening chemistry and moisture balance. Substituting by weight and adjusting leavener is more reliable.

Yaourt, fruits, faible en matières grasses, 9 g de protéines/227 g : conversion mL vers grammes

Par Fidamen-Chefsolver Team | Révisé par Chefsolver Staff

Low-fat fruit yogurt with 9 grams of protein per 8-ounce serving has a density of 1.036 g/ml, slightly above whole milk due to the combined effect of reduced fat, added fruit solids, and the thick gel structure formed by bacterial fermentation. One US cup weighs approximately 245 g and one tablespoon about 15.3 g. The low-fat designation means the milkfat content is between 0.5% and 2%, with fruit puree or concentrate adding sweetness, color, and additional dissolved solids that raise density above plain yogurt. The 9 g protein per 8 oz (227 g) serving reflects the concentrated casein and whey from the fermentation process. This product is commonly used as a breakfast food, smoothie base, or baking ingredient where its acidity activates baking soda for leavening.

Comment fonctionne cette conversion

Les millilitres mesurent le volume et les grammes le poids. La densité de Yaourt, fruits, faible en matières grasses, 9 g de protéines/227 g étant de 1.036 g/mL, 10 mL pèsent 10 g — et non 10 g comme ce serait le cas pour l'eau. Ce convertisseur utilise la densité réelle de Yaourt, fruits, faible en matières grasses, 9 g de protéines/227 g pour un résultat précis.

Notes de mesure

Les valeurs sont arrondies au gramme le plus proche. Le poids réel peut varier légèrement selon le tassement, la température et la marque. Pour la pâtisserie de précision, une balance de cuisine est toujours plus fiable que les mesures volumétriques.
