Myristica Fragrans

<p><em>Myristica fragrans</em> Houtt (nutmeg) is used as a spice and flavour for food and beverages. It has been traditionally used to treat a number of medical conditions, including diabetes mellitus. The study was undertaken to scientifically validate the traditional use of mace from <em>M.</em><em> </em><em>Fragrans</em><strong>. </strong>The objectives of this study were to evaluate α-glucosidase inhibition, antioxidant and antibacterial activities of water extract (WE) and essential oil (EO) from <em>M.</em><em> </em><em>fragrans</em> mace.  Both WE and EO were evaluated for their α-glucosidase inhibitory activities <em>in vitro</em> and their antioxidant activities based on DPPH radical scavenging assay. Standard compounds were used for every test. Total phenolic and flavonoid contents of both extracts were also determined. The extracts were also tested for their antibacterial activities against six different bacteria by a well diffusion method. Both extracts showed inhibition activities against α-glucosidase, with WE showed stronger activity than EO (IC<sub>50</sub> = 1.86 and 8.15 mg/ml). Good radical scavenging activities were observed for both extracts, with WE showed stronger activity than EO (IC<sub>50</sub> = 1.51 and 4.59 mg/ml). WE showed higher content in phenolic than EO (47.84 and 37.21 mg GAE/100 g DW). Flavonoid content in WE was also higher than EO (215.36 and 30.12 mg RE/ml). Based on the well diffusion method, only EO exhibited antibacterial activities, with inhibition zone in the range 1.03 – 1.30 mm.  The strongest activity was observed against<em> Staphylococcus mutans</em>. The results indicate WE and EO can be exploited further for pharmacological uses, in particular for their antidiabetic and antioxidant activities. </p>

Zataria Multiflora

Background: Nowadays, the application of several and natural preservatives in small quantity is a more preferred approach. In this regard, one of the effective methods is the formation of nanoemulsion of essential oils. Objective: The objective of this study was to compare the in vitro antibacterial activities of cinnamaldehyde (CIN) and Zataria multiflora essential oil in conventional (ZEO), nanoemulsion (NZEO) and fortified nanoemulsion (NZEOC) forms against common foodborne pathogens. Methods: Firstly, the Zataria multiflora essential oil was analyzed by GC-MS. The nanoemulsion of Z. multiflora essential oil was then prepared alone and fortified with cinnamaldehyde. Finally, their antimicrobial activity against Listeria monocytogenes, Staphylococcus aureus, Salmonella enteritidis and Escherichia coli was evaluated. Results: Based on the results, carvacrol (36.62%) was found to be the most important compound of essential oil. In disc diffusion and micro-dilution methods, the addition of CIN to ZEO during nanoemulsion formation (NZEOC) showed more antibacterial activity when compared to the individual addition of NZEO and CIN (NZEO+CIN). However, according to the vapor phase diffusion method, nano-treatments exhibited less inhibitory effects than the other treatments. Conclusion: It can be concluded that the fortification of essential oils with their derived pure compounds during nanoemulsion formation, can be used as a suitable alternative to chemical antibacterial compounds in the food industry.

Broth Microdilution Method

In vitro inhibition of foodborne pathogens via action of natural antimicrobials – caprylic acid (CA) and essential oil from Origanum vulgare L. (OEO) with high carvacrol content (72%) was evaluated. For 15 Salmonella strains the minimum inhibitory concentration (MIC) determined by broth microdilution method ranged between 3.67–4.33 μl·ml-1 for CA and between 0.48–0.57 μl·ml-1 for OEO. For 7 Listeria monocytogenes strains the MIC ranged between 2.17–2.83 μl·ml-1 for CA and between 0.52–0.58 μl·ml-1 for OEO. Type strains of Escherichia coli O157:H7 and Staphylococcus aureus were tested, too, with MIC of CA 3.60 μl·ml-1 and 3.20 μl·ml-1 and MIC of OEO 0.51 μl·ml-1 and 0.48 μl·ml-1, respectively. Furthermore, it was found that the MIC of CA can be decreased by even low addition (0.05%) of citric or acetic acid and to a lesser extent by lactic acid, whereas the MICs of OEO did not notably decrease. Combined application of CA and OEO determined by FIC index led only to an additive effect (0.5 ≤ FIC ≤ 1). Combination of natural additives OEO, CA and eventually acetic or citric acid seems to have the potential to be an effective mixture for inhibition of foodborne pathogens, predominantly Salmonella spp. and L. monocytogenes, even in only slightly acidic food.
