Antioxidant Activity and Antimicrobial Effect for Foodborne Pathogens from Extract and Fractions of Sanguisorba officinalis L.

The decontamination of food contact surfaces is a major problem for the food industry. The radiant catalytic ionization (RCI) method, based on the ionization process, may be an alternative for conventional decontamination procedures. The advantage of this technique is the possibility of its application to household refrigerating appliances and industrial cold rooms. This study aimed to assess the effect of RCI on the reduction of Campylobacter jejuni, Listeria monocytogenes, and Salmonella Enteritidis from the biofilms formed on a glass surface under refrigeration conditions. Bacterial biofilms were exposed to RCI for 24 h and after 12 (variant I) and 72 h (variant II) of the glass surface contamination. In the last variant (III), the contaminated meat was placed on the glass surface in the refrigerator and subjected to RCI treatment for 72 h. The significantly highest values of absolute reduction efficiency coefficient E were found for the bacterial attachment stage of biofilm formation (variant I). The research proves the efficiency of the RCI method in the reduction of bacteria number from a glass surface.

Tiger Nuts

Tiger nut (Cyperus esculentus) is a tuber that can be consumed raw or processed into beverages. Its nutritional composition shows a high content of lipid and dietary fiber, close to those of nuts, and a high content of starch, like in other tubers. Tiger nuts also contain high levels of phosphorus, calcium, and phenolic compounds, which contribute to their antioxidant activity. From those characteristics, tiger nuts and derived beverages are particularly relevant to limit food insecurity in regions where the plant can grow. In Europe and United States, the tiger nut derived beverages are of high interest as alternatives to milk and for gluten-free diets. Fermentation or addition of probiotic cultures to tiger nut beverages has proven the ability of lactic acid bacteria to acidify the beverages. Preliminary sensory assays concluded that acceptable products are obtained. In the absence of pasteurization, the safety of tiger nut-based beverages is not warranted. In spite of fermentation, some foodborne pathogens or mycotoxigenic fungi have been observed in fermented beverages. Further studies are required to select a tailored bacterial cocktail which would effectively dominate endogenous flora, preserve bioactive compounds and result in a well-accepted beverage.

This research was to investigate the chemical composition, antioxidant activity, and microbial profiles of Cola lepidota fruits. One hundred grams each of the fruit exocarp, mesocarp and endocarp were blended and analyses were carried out by the following standard methods. Active acidity and vitamin C contents were 5.5 and 6.34 mg 100 g–1 in endocarp, 4.5 and 14.39 mg 100 g–1 in mesocarp and 6.7 and 10.02 mg 100 g–1 for exocarp. Moisture and carbohydrate contents of 12.31 and 68.72% were in the mesocarp while protein and crude fibre contents of 8.13 and 26.18% were in the exocarp and endocarp. Iron (Fe), zinc (Zn) and manganese (Mn) contents were 1.79, 0.27 and 0.57 mg 100 g–1 in exocarp while lead (Pb), cadmium (Cd) and chromium (Cr) were absent in the endocarp. Predominant isolates were Aspergillus niger, Saccharomyces cerevisiae, Aspergillus flavus, Bacillus, Staphylococcus and Pseudomonas species. C. lepidota had no antimicrobial effect against the tested organisms. Tannins, flavonoids, terpenoids, phenols, coumarins and anthocyanins were present while alkaloids, quinolones, glycosides, steroids and cardiac glycosides were absent. The fruit was observed to have antioxidant property by hydrogen peroxide scavenging activity. This study presents C. lepidota as good for human consumption and can be exploited for animal feed production.

The selection and use of natural compounds with antimicrobial activity against foodborne pathogens is of major importance. The present study evaluated the antimicrobial activity of commercial essential oils against multidrug-resistant Enterococcus spp. and Aeromonas spp. Cymbopogon flexuosus and Thymus vulgaris essential oils presented the highest inhibitory zones against both bacterial groups ( p < 0.05). Subsequent determination of the minimum inhibitory concentrations showed values between 0.47 and 1.9 mg/ml for Aeromonas spp. and from 1.9 to 15 mg/ml for Enterococcus spp. The antimicrobial effect of C. flexuosus and T. vulgaris essential oils was also assessed against biofilms. Bacteria in biofilm state were subjected to 30 min or 1 h of exposure to each essential oil and eradication ability estimated by colony counting. Both essential oils exhibited antimicrobial activity against preformed Aeromonas biofilms, but were unable to successfully eradicate biofilms produced by enterococci, in the conditions under investigation. Nonetheless, the presumptive use of essential oils in the food industry should be considered in further investigations.
