Popular questions
Is calcium lactate dairy?
No—calcium lactate (E327) is a mineral salt of lactic acid and is not a dairy product; it contains no milk proteins or lactose.
What is calcium lactate good for?
It’s used to supply calcium and as a firming/thickening and acidity-regulating agent in foods; it’s also common in alginate spherification and for calcium fortification or supplementation.
Does calcium lactate contain dairy?
No, it doesn’t contain dairy; despite the name, it’s typically made by fermenting sugars or via synthesis and is free of milk proteins and lactose.
Does calcium lactate have dairy?
No—it's not derived from milk and does not have dairy components.
How to make popping boba without calcium lactate?
Use direct spherification: blend 0.5–1% sodium alginate into your flavored liquid, let it rest to de-bubble, then drip it into a 0.7–1% calcium chloride solution for 30–60 seconds and rinse to remove any bitterness.
Is potassium alum safe?
Yes—when used within legal limits in foods, potassium alum (E522) is permitted for limited uses and considered safe; nonetheless, total aluminum intake should stay below EFSA’s tolerable weekly intake of 1 mg/kg body weight, and people with kidney disease should be cautious.
Does potassium alum contain aluminum?
Yes; it’s a double sulfate salt (KAl(SO4)2·12H2O) that contains trivalent aluminum.
Is potassium alum aluminum?
No; it isn’t elemental aluminum but a sulfate salt that contains aluminum ions.
Is potassium alum bad for you?
Not at the small amounts allowed in foods; excessive aluminum exposure can be a concern—especially for people with impaired kidney function—so uses and levels are restricted.
Is potassium alum the same as aluminum?
No; potassium alum (aluminum potassium sulfate) is a compound containing aluminum, not the same as pure aluminum metal.
