Special Issue Information

Dear Colleagues,

Large amounts of agri-food by-products, non-edible food, and waste are produced throughout the supply chain from the initial production to the final consumption stages. The valorization of agri-food by-products to obtain high-added-value plant compounds such as phenolic compounds, dietary fiber, and active peptides have been the focus of extensive research in the last decade. Vegetables are a good source of these bioactive compounds, which possess antioxidative and antimicrobial properties; therefore, their use can be very useful to extend the food shelf-life and they are also shown beneficial effects for humans in terms of disease prevention. It is known that the extraction methods for obtain bioactive compounds can influence the efficiency, composition and activity of the compounds obtained from the by-products. For this reason, the study of bioactive compounds, their extraction methods and their functional properties would be very interesting to obtain compounds with high functional activity that could be applied in the food industry.

Therefore, we invite original research articles, short communications, and review papers covering this Special Issue on bioactive compounds obtained from plant sources.

This study identified the compounds obtained from four native Dehesa plants, which were holm oak, elm, blackberry and white rockrose, and evaluated their ability to inhibit the growth and production of aflatoxins B1 and B2 of two strains of mycotoxigenic Aspergillus flavus. For this purpose, phenolic compounds present in the leaves and flowers of the plants were extracted and identified, and subsequently, the effect on the growth of A. flavus, aflatoxin production and the expression of a gene related to its synthesis were studied. Cistus albidus was the plant with the highest concentration of phenolic compounds, followed by Quercus ilex. Phenolic acids and flavonoids were mainly identified, and there was great variability among plant extracts in terms of the type and quantity of compounds. Concentrated and diluted extracts were used for each individual plant. The influence on mold growth was not very significant for any of the extracts. However, those obtained from plants of the genus Quercus ilex, followed by Ulmus sp., were very useful for inhibiting the production of aflatoxin B1 and B2 produced by the two strains of A. flavus. Expression studies of the gene involved in the aflatoxin synthesis pathway did not prove to be effective. The results indicated that using these new natural antifungal compounds from the Dehesa for aflatoxin production inhibition would be desirable, promoting respect for the environment by avoiding the use of chemical fungicides. However, further studies are needed to determine whether the specific phenolic compounds responsible for the antifungal activity of Quercus ilex and Ulmus sp. produce the antifungal activity in pure form, as well as to verify the action mechanism of these compounds.
