Buckwheat achenes antioxidant profile modulates Aspergillus flavus growth and aflatoxin production.

摘要: Buckwheat (Fagopyrum spp.) is a "pseudo-cereal" of great interest in the production healthy foods since its flour, derived from achenes, enriched with bioactive compounds and, due to absence gluten, may be used composition celiac diets. Amongst buckwheat species, F. tataricum achenes possess larger amount antioxidant flavenol rutin than common esculentum. Ongoing climate change favor plant susceptibility attack by pathogenic, often mycotoxigenic, fungi consequent increase mycotoxins previously unexploited feeds and foodstuffs. In particular, Aspergillus flavus, under suitable environmental conditions such as those currently occurring Italy, produce aflatoxin B1 (AFB1), most carcinogenic compound fungal origin which classified IARC Category 1. this study, viable two (var. Golden) esculentum Aelita) were inoculated an AFB1-producing A. flavus NRRL 3357 analyze their relative performances against invasion toxin contamination. Notably, we sought existence correlation between tocols/flavonols buckwheat, infected non-infected ability pathogen grow during achene infection. Results suggest that tataricum, best producer are less susceptible infection consequently, but not proportionally, mycotoxin contamination compared Moreover, rutin-derived quercetin appears more efficient inhibiting biosynthesis parent compound.
