The objective of this study was to determine the potential antimicrobial activity of extracts and essential oils of spices from Thailand against foodborne pathogenic bacteria. The antimicrobial efficacy of ginger (Zingiber officinale), fingerroot (Boesenbergia pandurata), and turmeric (Curcuma longa) was evaluated against five strains of Listeria monocytogenes and four strains of Salmonella enterica ssp. enterica serovar Typhimurium DT104. Antimicrobial activity was investigated in microbiological media by using an agar dilution assay and enumeration over time and a model food system, apple juice, by monitoring growth over time. In the agar dilution assay, water extracts of the three spices had no effect on L. monocytogenes. Similarly, 50% ethanol extracts of ginger or turmeric had no effect. In contrast, ethanolic fingerroot extracts at 5 to 10% (vol/vol) inhibited most L. monocytogenes strains for 24 h in the agar dilution assay. Commercial essential oils (EO) of ginger or turmeric inhibited all L. monocytogenes at ≤0.6 or ≤10%, respectively. Fingerroot EO inhibited all strains at ≤0.4%. In the enumeration-over-time assay, a 5% fingerroot ethanol extract reduced ca. 4 log CFU/ml Listeria by around 2 log in 24 h while 10% inactivated the microorganism in 9 h. Fingerroot EO at 0.2% inactivated 4 log CFU/ml L. monocytogenes in 6 to 9 h. Neither extracts nor commercial EO had any effect on Salmonella Typhimurium DT 104 with the exception of fingerroot EO, which inhibited all strains at ≤0.7%. Addition of 0.2% fingerroot EO to apple juice reduced 4 log of L. monocytogenes Scott A and both strains of Salmonella Typhimurium to an undetectable level within 1 to 2 days. It was concluded that fingerroot EO and extract have potential for inhibiting pathogens in food systems.

The antimicrobial capability of chitosan from Tenebrio molitor as compared with chitosan from crustacean (Penaeus monodon) on different pathogenic microorganisms of concern in food safety was studied. The antimicrobial effect was tested at pH 5 and pH 6.2 and at two different initial concentrations (103 or 106 CFU/mL). Results indicated that chitosan from both sources have antimicrobial activity, although the effect depended on the microorganism considered (Salmonella Typhimurium, Listeria monocytogenes and Escherichia coli O157:H7). Our results indicated that Salmonella was the most resistant bacteria, and that chitosan from insect was less active than chitosan from crustacean, especially against Salmonella. Another important factor on antimicrobial activity was the pH of the sample. When chitosan was added to a solution with a pH of 6.2 it was more active against Listeria and Escherichia coli, than at pH 5.00. Besides, the effect of chitosan appears to decrease with the incubation time, since some increases in counts were observed on E. coli and Salmonella after the 24 and 49 hours of incubation.

Bologna and ham slices (300 of each) were inoculated with Salmonella Typhimurium or Listeria monocytogenes at 103 CFU/cm2. Alginate-based edible films that had been immersed in a 2 or 20% (wt/vol) CaCl2 solution and contained 1% (wt/vol) essential oils of Spanish oregano (O; Corydothymus capitatus), Chinese cinnamon (C; Cinnamomum cassia), or winter savory (S; Satureja montana) were then applied to slices to control pathogen growth. On bologna, C-based films pretreated with 20% CaCl2 were the most effective against the growth of Salmonella Typhimurium and L. monocytogenes. L. monocytogenes was the more sensitive bacterium to O-, C-, and S-based films. L. monocytogenes concentrations were below the detection level (<10 CFU/ml) after 5 days of storage on bologna coated with O-, C-, or S-based films pretreated with 20% CaCl2. On ham, a 1.85 log CFU/cm2 reduction of Salmonella Typhimurium (P ≤ 0.05) was found after 5 days of storage with C-based films regardless of the type of pretreatment used (2 or 20% CaCl2) or when coated with O-based films pretreated with 20% CaCl2. L. monocytogenes was highly resistant in ham, even in the presence of O-, C-, or S-based films. However, C-based films pretreated with 20% CaCl2 were the most effective against the growth of L. monocytogenes. Evaluation of the availability of active compounds in films revealed a significantly higher release of active compounds in C-based films (P ≤ 0.05) regardless of pretreatment or meat tested (bologna or ham). O-based films had the lowest release level of active compounds. The release of active compounds from O- and S-based films pretreated with 20% CaCl2 was faster than that in the same respective films pretreated with 2% CaCl2 regardless of the meat type. C-based film pretreated by immersion in a 20% CaCl2 solution was most efficient against both pathogens, and migration of active compounds was higher in C-based films than in O- and S-based films.
