Cultivating edible fungi is a crucial step in the entire growth process. Creating high-quality culture material is essential for successful mushroom cultivation. So, how can you prepare an excellent culture medium?
**Preparation:** Start by using 0.1% of the culture material as a fermentation aid (or 0.2% if reusing waste). Prepare the fermenting agent specifically for golden baby mushrooms. Soak the main ingredients—such as straw, wood chips, or other substrates—until they are moist but not soggy. Adjust the moisture content to around 60-70%, and ensure the pH level is about 8.
**Mixing:** Dilute the fermentation aid with fresh rice bran (avoid old or poor-quality rice bran). Use 5 kg of rice bran per 1 kg of fermentation aid. Then mix it evenly with the pre-wetted main ingredients, along with additives like bran, cake meal, and manure. Make sure everything is well blended before incorporating it into the main substrate.
**Piling:** Combine the raw materials using traditional methods. Create a pile and use a pointed tool (about 10 cm in diameter) to poke holes in the center for aeration. Cover the pile with breathable materials like sacks or straw mats to maintain warmth and moisture.
**Turning:** When the pile temperature reaches around 65°C, turn it for the first time. Repeat the process every 3–4 days. For Agaricus bisporus, the turning interval may be slightly longer.
**Temperature Control:** In the early stages of fermentation, the temperature might rise quickly to 70–75°C. If this happens, turn the pile immediately. Prolonged exposure to temperatures above 75°C can destroy nutrients and reduce yield. In later stages, adjust the temperature based on the needs of different mushroom species by removing covers, increasing aeration, watering, reducing pile height, or turning more frequently.
**Moisture Management:** As the pile heats up, moisture will evaporate. Monitor the humidity closely and add water when necessary—preferably using 0.5% lime water. The last watering and turning should be done together. Avoid adding too much water during sowing, as this could lead to "raw water" and prevent the mycelium from colonizing properly.
**Completion:** For oyster mushrooms and straw mushrooms, the fermentation process usually takes 5–6 days. For Agaricus bisporus, it may take 10–15 days. Once fully fermented, the material should have about 65% moisture, appear brown, and be covered with white mycelium. It should not smell ammonia-like, feel sticky, or be overly soft. If the straw pulls easily, the fermentation is complete. For more details, visit our website or contact us directly.
Puffed Corn Flour
Puffed corn flour is a type of flour made from corn that has been puffed or expanded through a process of heat and pressure. The process involves heating the corn kernels until they become soft and moist, and then rapidly releasing the pressure, causing the kernels to puff up. The puffed corn is then ground into a fine flour that can be used in a variety of recipes. Puffed corn flour is often used as a gluten-free alternative to wheat flour in baking and cooking, and is also used in snack foods such as popcorn and corn chips. It is high in fiber and protein, and has a light, airy texture that makes it ideal for use in baked goods.
