What is Tempeh?
Tempeh is a fermented soybean product native to Indonesia. It serves as a rich source of protein and contains a variety of essential nutrients, making it a popular addition to vegetarian and vegan diets. The unique fermentation process gives tempeh a nutty flavor and a firm texture, distinguishing it from other soy products such as tofu.
The Fermentation Process
The process of making tempeh involves the fermentation of cooked soybeans with the help of a specific mold called Rhizopus oligosporus. Here’s a breakdown of the steps involved in producing tempeh:
- Soaking: Dried soybeans are soaked in water for several hours to soften them.
- Cooking: The soaked beans are then boiled until they are tender.
- Inoculation: After cooling, the beans are inoculated with the tempeh starter culture, which contains spores of Rhizopus oligosporus.
- Fermentation: The inoculated beans are placed in a breathable container and left to ferment at a warm temperature for 24-48 hours.
- Harvesting: Once the fermentation is complete, the beans have bonded to create a cake-like structure that can be sliced and cooked.
