Evaluation of biological and antimicrobial properties of freeze-dried whey fermented by different strains ofLactobacillus plantarum
The aim of this study was to evaluate the biological and antimicrobial activities of commercial freeze-dried whey fermented by lactic acid bacteria in order to valorize this high polluting liquid waste of the dairy industry. Freeze-dried whey was fermented by different strains of Lactobacillus plantarum (CECT 220, 221, 748) at three different times of fermentation (24, 48, 72 h). Afterwards, the extract was purified on centricon amicon with a cut-off of 3 kDa to obtain a permeate consisting of small bioactive compounds reported in the literature to show greater bioactivity. The purified and diluted samples were subjected to the biological and antimicrobial tests for the evaluation of antiox…
Fusaproliferin, beauvericin and enniatins: occurrence in food – a review
The present review summarises data on the prevalence and concentration of fusaproliferin, beauvericin and enniatins in small grains, maize and processed grain-based foods. These fungal secondary metabolites possess interesting biological activities and are presently often referred to as 'emerging mycotoxins'. They have been considered as less important since they are likely not of acute toxicity. However, their high prevalence in foodstuffs, occasionally in higher mg/kg concentrations, warrants an assessment of their true importance for food (and feed) safety. Thorough surveys that determine the contamination of raw and processed foods with fusaproliferin, beauvericin and enniatins are sti…
