Can phenolic compounds be used for the protection of corn from fungal invasion and mycotoxin contamination during storage?

摘要: The effect of natural phenolic compounds (vanillic and caffeic acid) water activity (a(w)) on the growth mycotoxin production corn by Fusarium Aspergillus isolates was investigated. Large differences were observed in response to compounds, mostly determined their genus. Generally for both F. verticillioides proliferatum, an increase concentration either or vanillic acid resulted a decrease colony rate lag phase duration. Growth not completely inhibited at highest a(w) value evaluated 0.967, with complete inhibition only being combinations high concentrations (> =2000 microg g(-1)) low values (0.948). Within experimental limits investigated, species affected compounds. Application significantly reduced fumonisin B(1) aflatoxin production. Although effects noted artificial media appear be carried over corn, rather are required observe similar inhibit where possible. This implies occurrence interactions some matrix components which may reduce overall effectiveness.
