Soy Milk FAQ
Is tonyu the same as soy milk? Can you microwave it? Why does it settle? We have gathered the soy milk questions people search for most, from the basics to storing, heating and pairing.
Soy milk basics
What is tonyu? Is it the same as soy milk?
Yes. Tonyu (豆乳) is the Japanese word for soy milk, and in Taiwan it is often used for soy milk drinks, such as a tonyu latte or tonyu black tea. SOYCLUB 全豆豆乳 is our whole soy milk.
Is soy milk the same as soy drink?
Usually they mean the same kind of drink. Some products labelled soy drink are flavoured or contain extra ingredients, so the ingredients list is the clearest guide.
How is whole soy milk different from regular soy milk?
Regular soy milk is filtered to remove the pulp, while whole soy milk grinds the entire soybean very finely and keeps it, so it tastes richer. See what is whole soy milk.
How is soy milk different from dairy milk?
Soy milk is plant-based and lactose-free; dairy milk comes from cows and contains lactose. Their taste and nutrition differ. See soy vs dairy vs oat milk.
Storing and heating
How long does soy milk keep after opening?
Follow the storage instructions and dates on the pack. In general, refrigerate after opening and finish it soon. If it smells sour, smells off or is clearly lumpy, don't drink it.
Does soy milk need to be refrigerated?
Refrigerate it once opened. Store unopened products as directed on the pack.
Is it OK to drink soy milk with sediment?
Whole soy milk keeps the whole bean, so some settling at the bottom is normal. Just shake before drinking. If it also smells sour or off, or is past its date, don't drink it.
Can you microwave soy milk?
Yes, but pour it into a microwave-safe container rather than heating the carton. Heat in short bursts, stirring in between, until it just steams so it doesn't boil over.
Why does soy milk form a skin when heated?
As soy milk heats, proteins on the surface set into a thin film, known as yuba. Heat it gently and stir to reduce the skin.
Soy milk curdled when heated. Is it safe?
Soy proteins can set when very hot or mixed with something acidic, which is normal. But if the soy milk already smells sour or off, or is past its date, curdling may mean it has spoiled, so don't drink it.
Can you freeze soy milk?
Yes, but it may separate and feel less smooth after thawing. Shake well before drinking, or use it in pancakes or porridge.
Pairing and drinking
Can I add coffee to soy milk?
Yes, that's a soy latte. For iced, use 30ml of espresso with 180ml of soy milk. See how to make a soy latte.
Why does soy milk curdle in coffee?
Soy proteins can clump in hot, acidic coffee. Pour the soy milk first, keep both at a similar temperature and choose a medium-dark roast.
Can I add honey to soy milk?
Yes. Honey dissolves easily in warm soy milk; for cold soy milk, loosen the honey with a little warm water first.
What goes well with soy milk?
Coffee, matcha, black tea, brown sugar, cocoa, banana, black sesame and oats. See what to add to unsweetened soy milk.
When is a good time to drink soy milk?
Breakfast, an afternoon break or after exercise, whatever suits your routine. For ideas, see soy milk breakfasts.
Can I cook with soy milk?
Yes. Use it instead of dairy milk in pancakes, porridge and French toast, or in soups and desserts. Try our soy milk pancakes.
Good to know
Can I drink soy milk every day?
Soy milk can be part of an everyday diet. Needs vary, so enjoy it as part of a balanced diet, and talk to a doctor or dietitian if you have a health condition or dietary restriction.
Can people be allergic to soy milk?
Yes. Soy is a common food allergen. People with a soy allergy should avoid soy milk and soy products.
Can soy milk cause bloating?
Some people feel bloated after drinking legume-based drinks; it varies from person to person. Start with a small amount and see how you feel.
