The growing demand for food free of synthetic preservatives has motivated the industry to seek new alternatives to combat deterioration and microbial contamination, sources of large economic losses. Furthermore, diseases transmitted by foods are among the largest public health problems today, and Salmonella enteritidis is one of the most important etiological agents. In this context, the research for new natural antimicrobials for use in foods is of utmost importance, and Brazil , a country with large territory and rich biodiversity, is an inexhaustible source of raw material in this field. Its economy, based heavily on agribusiness, allows the generation of large amounts of industrial residues, which are discarded directly into the environment, which can cause significant environmental damage. Many of these residues are rich in bioactive substances, including antimicrobials. The research for new compounds with antimicrobial activity in residues, such as grape, guava, tomato, orange, passion fruit and green vegetables (carrot leaves, radish, artichoke, stalks of sugar beet, kale, broccoli, pea pods) will help to reduce the environmental damage generated by the discard of industrial by-products, besides providing for the food industry economic gains with the use of natural preservatives and greater acceptance of its products by consumers who will benefit from an improved quality of life.
