Bread is a food that is commonly recognized as a very convenient type of food, but it
is also easily prone to microbial attack. As a result of bread spoilage, a significant economic loss
occurs to both consumers and producers. For years, the bakery industry has sought to identify
treatments that make bread safe and with an extended shelf-life to address this economic and safety
concern, including replacing harmful chemical preservatives. New frontiers, on the other hand, have
recently been explored. Alternative methods of bread preservation, such as microbial fermentation,
utilization of plant and animal derivatives, nanofibers, and other innovative technologies, have
yielded promising results. This review summarizes numerous research findings regarding the
bio-preservation of bread and suggests potential applications of these techniques. Among these
techniques, microbial fermentation using lactic acid bacteria strains and yeast has drawn significant
interest nowadays because of their outstanding antifungal activity and shelf-life extending capacity.
For example, bread slices with Lactobacillus plantarum LB1 and Lactobacillus rossiae LB5 inhibited fungal
development for up to 21 days with the lowest contamination score. Moreover, various essential
oils and plant extracts, such as lemongrass oil and garlic extracts, demonstrated promising results
in reducing fungal growth on bread and other bakery products. In addition, different emerging
bio-preservation strategies such as the utilization of whey, nanofibers, active packaging, and modified
atmospheric packaging have gained considerable interest in recent days.
