Fermented products are foods and beverages that have undergone controlled microbial growth and fermentation, a natural process where bacteria, yeast, or other microorganisms break down sugars and starches.
This not only helps preserve the product but also enhances its flavor, nutritional value, and digestive benefits.
Interestingly, the global demand for fermented products is on the rise as more consumers seek natural, probiotic-rich options for better gut health and wellness.
If you’re an entrepreneur interested in starting a fermented product business, diving into DIY fermented goods can be a great way to begin.
These products often require minimal equipment and offer a low-cost entry into the health food market.
From kombucha and sauerkraut to kimchi, yogurt, kefir, and fermented hot sauces, the options are diverse and appealing.
