Tempeh Production A Craft And Technical Manual
Tempeh is a traditional Indonesian food made from soybeans. It is a fermented food that is rich in protein, vitamins, and minerals. Tempeh has become increasingly popular in the Western world due to its nutritional value and versatility in cooking. Making tempeh is a craft that requires a combination of technical knowledge and experience. This article will provide a comprehensive guide on tempeh production, covering both the craft and technical aspects.
The Ingredients
The basic ingredient for making tempeh is soybeans. The soybeans must be of good quality and free from impurities. Other ingredients include a starter culture, usually in the form of Rhizopus mold, and water. The starter culture is what initiates the fermentation process. It is important to use a high-quality starter culture to ensure a successful fermentation process.
The Equipment
The equipment needed for making tempeh includes a pot, a strainer, a thermometer, a plastic bag, and a perforated tray. The pot is used for boiling the soybeans, while the strainer is used for draining the water. The thermometer is used to monitor the temperature of the soybeans during the fermentation process. The plastic bag is used to enclose the soybeans and starter culture, while the perforated tray is used to allow air circulation.
The Process
The process of making tempeh involves several steps. The first step is to soak the soybeans in water for several hours. The soybeans are then boiled until they are soft. The next step is to drain the water and cool the soybeans. The starter culture is then added to the soybeans, which are then mixed thoroughly. The soybeans and starter culture are then enclosed in a plastic bag and left to ferment for 24-48 hours at a temperature of 30-32°C. After fermentation, the tempeh is ready to be consumed.
The Science Behind Tempeh Production
The fermentation process in tempeh production is initiated by the Rhizopus mold. The mold breaks down the carbohydrates in the soybeans into simpler sugars, which are then used by the mold as a source of energy. The mold also produces enzymes that break down the proteins in the soybeans into amino acids. This process increases the nutritional value of the soybeans and makes them more digestible. The fermentation process also produces a distinct flavor and aroma in the tempeh.
Tips for Successful Tempeh Production
Successful tempeh production requires attention to detail and careful monitoring of the fermentation process. Here are some tips for successful tempeh production:
- Use high-quality soybeans and starter culture.
- Ensure that the soybeans are cooked properly.
- Maintain a consistent temperature of 30-32°C during fermentation.
- Ensure proper air circulation by using a perforated tray.
- Monitor the fermentation process closely and adjust as necessary.
The Benefits of Tempeh
Tempeh is a nutritious food that offers many health benefits. Here are some of the benefits of tempeh:
- High in protein: Tempeh is a great source of protein, with about 20 grams of protein per 100 grams.
- Rich in vitamins and minerals: Tempeh is rich in vitamins B3, B6, and B12, as well as iron, magnesium, and calcium.
- Good for digestion: The fermentation process in tempeh increases its digestibility and makes it easier to digest.
