Production of enniatins A, A1, B, B1, B4, J1 by Fusarium tricinctum in solid corn culture: structural analysis and effects on mitochondrial respirati…
2013
Enniatins (ENs) are secondary fungal metabolites with hexadepsipeptidic chemical structure and they possess a number of potent biological activities that can contaminate several kind of food and foodstuffs increasing the exposure risk for consumers. ENs are produced by several Fusariun strains including Fusarium subglutinans, Fusarium proliferatum and Fusarium tricinctum. Production of a mixture of ENs was performed by culturing F. tricinctum ITEM 9496 on white corn as substrate. The solid culture components were dried and subsequently extracted with water/methanol (50/50 v/v, 0.5% NaCl), homogenised, filtered, extracted by ethyl acetate and analysed by liquid chromatography with diode arra…
Bioaccessibility of glucoraphanin from broccoli using anin vitrogastrointestinal digestion model
2014
This study investigated the effect of cooking methods on the degradation of glucoraphanin (GR) in broccoli and the bioaccessibility of this compound through simulated gastrointestinal digestion. Broccoli was cooked using three different techniques: boiling, steaming and microwave cooking. Then, GR was extracted and quantified by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). In addition, the cooked samples were added to a system that simulates the digestion characteristics of the mouth, stomach and duodenum. Samples were drawn before and after the digestion, and GR bioaccessibility was calculated. GR losses were higher when broccoli was boiled (47.03%), followed by …
