There's is no minimum or maximum amount. We only advice that tempeh is part of a well balanced diet. The FDA recommends consuming daily about 25 g of soy proteins, or 2 to 3 oz Tempeh.
What soybean varieties are suitable for the production of tempeh?
The only beans in our opinion to create the taste of original Indonesian Tempeh are Yellow Soy Beans, although there are no specific varieties which could be used for the production of tempeh. To obtain the "fresh nutty taste" of Tempeh only the big yellow Soy Bean should be used, if you want to use instead of Soya Bean, an other kind of bean, this is no problem in the process, it only gives a different taste then Indonesian style tempeh.
Can I eat raw tempeh?
Fresh tempeh is eaten cooked, either fried, steamed or boiled.
How do I know that my tempeh is good?
In fresh tempeh the soybeans should be bound together into a tight cakes with no mold growing other than the white tempeh culture. Small black spots may occasionally appear. These spots do not necessarily indicate spoilage, but are part of the tempeh culture's life cycle.
The texture should not be slimy and the aroma should be mushroom-like (or nutty yeast-like). A every slight smell of ammonia is normal. This smell will increase if you incubate the tempeh too long, indicating that the proteins have been broken down too much.
My batch of homemade tempeh is spoiled, who can I prevent this in future?
There could be many reasons but the most important one is the incubation of moist beans. Moist is the number 1 reason which will spoil your batch of Tempeh. Then other organisms will grow and compete with the tempeh mold. This will result in a slimy texture and a strong smell of ammonia.
Other reasons could be:
- using old or inactive starter(starter should be kept in a dark, cold and dry place)
- working conditions were not hygienisch
- too high incubation temperature which kills the mold (temperature should be 86 F).
Molds can produce toxins! How safe is tempeh?
The molds (Rhizopus) used for the production of tempeh are eatable and don't produce any known toxins.
My tempeh has some black spots! Can I still use this tempeh?
The formation of black spores, especially around the air holes, where there's a lot of oxygen, the molds could produce some black spores. This tempeh is still eatable, and is normal. To Indonesian people black spores are a sign of a good tempeh(maker).
Depending on the Rhizopus strain could will happen sometimes after 2-3 days of incubation. To produce white tempeh, carefully follow our instructions,if the temperature is too hight or incubation time too long this could happen, our spores strain produces perfect tempeh, if directions are followed.
