Emerging evidence suggests that fermentation, historically used for the preservation of perishable foods, may be considered as a useful tool for increasing the nutritional value of fermented products, in terms of increases in bioactive compound content, including short-chain fatty acids (SCFAs), as bacteria end-products, whose beneficial effects on human health are well-established. The purpose of the present manuscript is to summarize studies in this field, providing evidence about this novel potential of fermentation. A limited number of studies directly investigated the increased SCFA levels in fermented foods. All studies, however, agree in confirming that levels of SCFAs in fermented products are higher than in unfermented products, recognizing the key role played by the microorganisms in metabolizing food matrices, producing and releasing bioactive substances. According to the available literature, fermentation might be taken into account by the food industry as a natural strategy with no environmental impacts to produce functional foods and beverages with a higher nutritional value and health-promoting compounds. |
