Lactosérum, acide, liquide : combien de grammes dans une cuillère ?
Acid whey is the thin, pale-green liquid byproduct of making fresh cheeses like cottage cheese, cream cheese, and strained Greek yogurt, with a density of 1.040 g/ml. One US cup weighs approximately 246 g and a tablespoon about 15.4 g. Its tangy, acidic profile with a pH around 4.5 makes it useful as a natural tenderizer in marinades, a liquid base for lacto-fermented vegetables, and a sourdough bread ingredient where its lactic acid boosts flavor and dough extensibility.

Questions fréquentes
- What makes acid whey different from sweet whey in terms of density and use?
- Both acid and sweet whey share a density of 1.040 g/ml, but acid whey has a pH around 4.5 versus 6.0 for sweet whey, giving it a sharper tang that works better in marinades and fermented recipes while making it less suitable for neutral-flavored protein drinks.
- Can acid whey be used as a buttermilk substitute in baking?
- Yes, acid whey at 1.040 g/ml and pH 4.5 provides similar acidity to buttermilk, effectively activating baking soda in pancake and biscuit recipes; however, it is thinner and less creamy, so the batter may be slightly more liquid.
- How should acid whey be stored to maintain its 1.040 g/ml density?
- Refrigerate acid whey in a sealed container for up to 5 days; as it ages, continued fermentation by residual bacteria can produce gas and slightly reduce its effective density through carbonation, making older whey less reliable for precise recipe scaling.
