Kimchi is usually produced by fermenting cabbage with lactic acid bacteria. Consider Kimchi, a traditional Korean food. DNA sequencingĭuring different stages of fermentation, the ratio of microbial populations can change with slight shifts in temperature and pH. Tempeh: The product of fermenting cooked soybeans, which binds the soybeans into a cake-like form. Mead: An alcoholic beverage made from fermenting honey with water, and can also include fruits, spices, grains, or hops.ĥ. Miso: A Japanese seasoning or paste made from fermenting mashed soybeans and grains mixed with salt.Ĥ. Kombucha: Fermented black or green tea drink known for its supposed health benefits.ģ. Kimchi: Common in Korean cuisine, and made from fermented vegetables like cabbage and radish.Ģ. For example, modern gene sequencing, genetic engineering, microfluidics, and electronic “nose” technologies can make our favorite fermented foods even tastier. Although our ability to control fermentation is reasonably understood, there are still many ways industrial fermentation can be improved. Since then, we have produced a variety of fermented foods including the popular Kombucha. It was not until the early 1900s that Nobel Laureate Eduard Buechner discovered that fermentation can occur with cell-free yeast extracts consisting only of enzymes, contrary to what Pasteur proposed. This serendipitous incident was instrumental to our modern day understanding that fungi and bacteria perform fermentation differently. These objects were later confirmed to be lactic acid bacteria. The sour beetroot mixture also contained many objects smaller than yeasts. Pasteur was tasked to investigate the issue and found that instead of alcohol, the “spoiled” beetroot mixture contained mostly lactic acid, which caused a sour taste. In 1856, an accident at a sugar beetroot distillery led to a groundbreaking discovery that was pivotal to subsequent production of cheese and yogurt.

Through a series of experiments, Louis Pasteur, a French microbiologist, showed that wine fermentation is caused by a type of fungi known as yeasts (and we do have a lot of them on our feet, gulp!) In the 17 th century, the hypothesis was validated when the invention of high-quality optical lens allowed visualization of single-celled microorganisms for the first time.

The transfer of microorganisms from the feet of wine producers to crushed fruits was hypothesized to cause fermentation. In the old days, wine producers typically crushed fruits with their feet before leaving them to sit in containers. Wine fermentation was documented as early as 7000 BC. Hence, the difference between apple cider and apple cider vinegar used for cooking.

  • Acetic acid fermentation: This oxidation process converts sugars from grains or fruit into sour tasting vinegar and condiments.
  • Ethanol (or alcohol) fermentation: In this type of fermentation, pyruvate molecules in sugars are broken down by yeasts into alcohol and carbon dioxide molecules to produce wine and beer, as well as bread.

    Lactic acid fermentation is commonly used in the production of foods like yogurt, pickles, and sauerkraut. Lactic acid bacteria not only protect foods from microbial spoilage, they protect the body from microbial disease. Lactic acid fermentation: During this anaerobic process, starches or sugars are broken down to produce lactic acid, among other waste products.That is also why food companies take extreme care to safeguard their recipes and maintain their biobanks of microorganisms. Therefore, when the types and numbers of microorganisms are changed, the taste of fermented food can also change dramatically. Their cooperation produces beautiful music-our favorite fermented food. microorganisms) have their respective roles. The process is akin to a concert where different musicians (i.e. During fermentation, a variety of microorganisms are present in different proportions. Microorganisms such as bacteria and fungi have unique sets of metabolic genes, allowing them to produce enzymes to break down distinct types of sugar metabolites. What is fermentation?įermentation is the process of sugars being broken down by enzymes of microorganisms in the absence of oxygen. Have you ever wondered what goes on during fermentation and the role of microorganisms in this process? This article provides a short historical walkthrough of fermentation, followed by a discussion on how modern biotechnologies can help make your favorite fermented food tastier. Attributing to their purported health benefits, they are also becoming more popular. You name it: fermented foods are now a huge part of our diet.
