Sprouts contain minerals, vitamins, and other compounds, which may have antimicrobial activity. Antimicrobial compounds are released from homogenized sprouts and diffuse into the culture medium inhibiting the growth of pathogenic bacteria. These antibacterial compounds may influence the multiplication of contaminating pathogens. In this study the antimicrobial effects of 55 different homogenized sprouts were investigated with agar well diffusion method on human pathogenic bacteria. Homogenizates of different radish, early kohlrabi, and red cabbage sprouts caused inhibitory zone around the wells on the surface of inoculated agar plates. Mustard, zucchini, medical (German) chamomile, spicy fenugreek, and adzuki bean sprouts had antimicrobial effect only against a few human pathogenic bacteria. Twenty-nine other spicy and vegetable sprouts had no antibacterial activity against the investigated human pathogens. The results suggest that a few sprouts have antimicrobial properties, but different cultivars of the same species have different effects against different bacterial strains. The sprouts of radish cultivars contained the most effective antibacterial compounds.

“…Rajkowski et al (2006) found the D 10 -values for Salmonella DT 104 in three ground pork products with the gamma process were in a range of 0.54 _ 0.66 kGy (Rajkowski et al, 2006) and the D 10 -value of S. Typhimurium in chicken breast meat was in a range of 0.51 _ 0.58 kGy (Kudra et al, 2011). Moreover, in three ready-to- ( Monk et al, 1995) and a lower water content in spices lead to higher resistances (Waje et al, 2009). Meanwhile, an investigation has found that E. coli was not resistant to irradiation that can be controlled under a dosage to inhibit total number of colonies (Ma et al, 2013).…”

“…The D 10 -value for each pathogen was determined using Excel's linear regression analysis by calculating the negative reciprocal of the survival slope (Rajkowski et al, 2006;Kim et al, 2010;Mustapha et al, 2014). To avoid possible shoulder effect, the zero-dose values were excluded from the calculation and at least four detectable data points were used to calculate the slopes and D 10 -values (Rajkowski et al, 2006;Waje et al, 2009;Kundu et al, 2013). However, due to the limited detectable data, two to three data points were used to calculate D 10 -…”

The widespread contamination of food by mycotoxins may present a serious hazard to human and animal health. The gamma rays were applied to reduce ochratoxin A (OTA) and aflatoxins B 1 , B 2 , G 1 and G 2 (AFB 1 , AFB 2 , AFG 1 and AFG 2 ) in almonds artificially contaminated. In the present study we investigated the effect of gamma irradiation dosages, ranging from 0 to 15 kGy and the reduction of mycotoxins concentration in almond samples. In order to determine the efficiency of the method, a high-performance liquid chromatography method with fluorescence detection was used, the mycotoxins were extracted from almond samples and then purified with immunoaffinity columns. The maximum reduction was found at 15 kGy and it was 19.25%, 10.99%, 21.11%, 16.62%, 23.90% for AFB 1 , AFB 2 , AFG 1 , AFG 2 and OTA respectively. Results showed that gamma radiations even at 15 kGy, were not effective in completely destroying aflatoxins and ochratoxin A.
