Bokashi composting is an innovative and efficient way to manage food waste, and making your own Bokashi bran can save time and money. Jason from Fraser Valley Rose Farm provides a step-by-step guide on creating Bokashi bran from scratch using rice wash, allowing you to harness the power of lactobacillus bacteria for your composting system. This article will walk you through the process, explain its benefits, and provide practical tips for success.
Why DIY Bokashi Bran?
Using rice wash to make Bokashi bran offers a cost-effective and straightforward alternative to commercial starter liquids. While proprietary blends often include lactobacillus, photosynthetic bacteria, and yeast, lactobacillus dominates these mixes by a significant margin. The DIY method leverages naturally occurring lactobacillus, offering comparable effectiveness for Bokashi composting. Plus, starting from rice wash means you can avoid the time and expense of sourcing specialized products.
Step 1: Extracting Rice Starch
The first step involves washing rice to extract starch, which will serve as a food source for the lactobacillus bacteria.
- What You’ll Need: One cup of rice, two cups of non-chlorinated water, a mason jar, and cheesecloth.
- The Process: Add the rice to the water and stir to release the starch. Once the water turns cloudy, pour it into the mason jar, filling it halfway. Cover the jar with cheesecloth to allow airflow and place it in a cool, dark cupboard for one week.
This simple preparation allows the rice starch to attract and support the growth of lactobacillus bacteria.
Step 2: Fermenting with Milk
After a week, the rice wash will show a slight film on top and sediment at the bottom. The next step is to amplify the lactobacillus population using milk.
- What You’ll Need: The fermented rice wash, a mason jar, and milk (any kind will do).
- The Process: Extract the middle layer of the rice wash, avoiding the top film and bottom sediment. Mix approximately 2.5 ounces of the liquid with milk in a mason jar, filling it nearly to the top. Cover the jar lightly to allow gas to escape during fermentation.
Leave this mixture in a cool, dark space for two weeks, during which it will separate into curd and whey. The whey contains concentrated lactobacillus and will be used in the next step.
Step 3: Preparing the Bran Mixture
Now it’s time to inoculate the wheat bran with the lactobacillus-rich whey.
- What You’ll Need: 10 pounds of wheat bran, 12 cups of warm non-chlorinated water, four tablespoons of molasses, and the whey.
- The Process: Dissolve the molasses in the water, then add four tablespoons of whey. Gradually mix the liquid into the wheat bran until it reaches a damp consistency. It should form a loose ball when squeezed but crumble easily.
Transfer the mixture into a black garbage bag, press out excess air, and seal it. Allow it to ferment in a warm, dark place for two weeks.
Step 4: Drying and Storing
After two weeks, the Bokashi bran will have a pickled smell, indicating successful fermentation. Spread the bran thinly on a clean surface to dry completely. Once dry, store it in an airtight container, such as a bucket with a lid, to keep it ready for use. While drying isn’t mandatory, it ensures the bran can be stored for extended periods without spoiling.
Tips for Success
- Moisture Control: The bran should be moist but not soggy. Overwatering can hinder the fermentation process.
- Storage: Properly dried and stored bran remains effective for months, ensuring a steady supply for your Bokashi system.
- Adaptability: If you have access to a commercial starter liquid, you can skip directly to Step 3 using the same proportions.
Why Bokashi Composting Works
Bokashi composting accelerates food waste decomposition using beneficial microorganisms. The lactobacillus bacteria in the bran break down organic matter while suppressing pathogens and odors. It’s an excellent option for those looking to reduce kitchen waste and create nutrient-rich compost.
Conclusion
Creating your own Bokashi bran from rice wash is a rewarding and practical project. By following Jason’s method, you’ll have an effective composting solution that’s cost-efficient and sustainable. Whether you’re new to Bokashi composting or looking to optimize your system, this DIY approach offers a reliable alternative to commercial products.
