On the other hand, Image: watermelon.org because these types of food contain certain live bacteria at the time of ingestion that continue to act once they are in our bodies. These are what we know as probiotics. As we will see further on, the microrganisms produced by these foods are key for our health. 6 Rediscovering Fermented Foods We shouldn’t confuse probiotics (live microrganisms administered in suitable quantities lending health benefits to the host), with prebiotics. The Tsang Image: Cleaneatingmag / Ronald latter are products that serve as food for bacteria that we have in our body and for this reason they are also critical to our health. These include food with a high fiber content, which acts as suste- nance to these microrganisms, such as leeks, garlic, onion and artichokes. One of the benefits of fermentation is that it creates an acidic environment that impedes the spread of new bacteria. 7 Rediscovering Fermented Foods Shelf Life A Homemade Process Another one of the interesting aspects of fer- As mentioned, fermentation is a process dating mented foods is their shelf life.

In olive-growing regions of Spain, families pick- le their own olives to consume as an appetizer. The fungus that enables the production of kefir is shared between friends and family so that it can be made at home. Brewing kombucha has also become as zen as having a bonsai tree - those who do it at home share pictures of their SCOBY on Instagram. Despite all this, there are more and more commer- cial brands that have standardized many processes and flavors, making these products more widely available on the market. This benefits consumers greatly, bearing in mind that the unique homemade processes take more time and effort. Image: Lancaster online Image: Lancaster The problem lies in organolepsy. In order to maintain its desired flavor throughout its shelf life, the product must be kept refrigerated, because at room temperature the process of fermentation will continue and as a result, alter the food further.
