Kinetics Of

Essential oils (EOs) have promising antioxidant activities which are gaining interest as natural alternatives to synthetic antioxidants in the food and cosmetic industries. However, quantitative data on chain-breaking activity and on the kinetics of peroxyl radical trapping are missing. Five phenol-rich EOs were analyzed by GC-MS and studied by oxygen-uptake kinetics in inhibited controlled autoxidations of reference substrates (cumene and squalene). Terpene-rich Thymus vulgaris (thymol 4%; carvacrol 33.9%), Origanum vulgare, (thymol 0.4%; carvacrol 66.2%) and Satureja hortensis, (thymol 1.7%; carvacrol 46.6%), had apparent kinh (30 °C, PhCl) of (1.5 ± 0.3) × 104, (1.3 ± 0.1) × 104 and (1.1 ± 0.3) × 104 M−1s−1, respectively, while phenylpropanoid-rich Eugenia caryophyllus (eugenol 80.8%) and Cinnamomum zeylanicum, (eugenol 81.4%) showed apparent kinh (30 °C, PhCl) of (5.0 ± 0.1) × 103 and (4.9 ± 0.3) × 103 M−1s−1, respectively. All EOs already granted good antioxidant protection of cumene at a concentration of 1 ppm (1 mg/L), the duration being proportional to their phenolic content, which dictated their antioxidant behavior. They also afforded excellent protection of squalene after adjusting their concentration (100 mg/L) to account for the much higher oxidizability of this substrate. All investigated EOs had kinh comparable to synthetic butylated hydroxytoluene (BHT) were are eligible to replace it in the protection of food or cosmetic products.

Bactericidal Properties

Plants produce compounds with antimicrobial properties that can be used to control diseases of horticultural products, for this reason, the aim of this study was to enlarge the knowledge on the effect of essential oils as an alternative for control for bacterial canker Clavibacter michiganensis subsp. michiganensis (Smith) (Cmm). Essential oil of Lippia palmeri was obtained by hydridestillation from plants collected in Sonora, Mexico. Essential oils of Origanum vulgare, Thymus vulgaris and Cinnamomum zeylanicum were obtained from commercial stores in Hermosillo, Sonora, Mexico. To evaluate the effect of the essential oils on the bacterium Cmm, direct applications in two concentrations (1:1 and 1:5 (v/v)) on tomato plants foliage were carried out. Then, plants were inoculated with 1x10-7 CFU/mL of the bacterium and observed for 12 days. The evaluated parameters were incidence and severity. The essential oils and chemical compounds of Origanum vulgare and Thymus vulgaris had effect against Clavibacter michiganensis subsp. michiganensis up to 9 days after application in a 1:1 (v/v) concentration and up to 12 days after application with the 1:5 (v/v) concentration. The essential oil of Lippia palmeri only had effect until six days after the application with both concentrations; that is to say, only these three types of essential oils had bactericidal properties, since with the essential oil of Cinnamomum zeylanicum the inhibition of Cmm was very limited, both in incidence as in severity.

Abstract The essential oils of Thymus vulgaris L. and Origanum vulgare L. were investigated for their toxicity and physiological aspects on the lesser mulberry pyralid Glyphodes pyloalis Walker in controlled condition (24±1°C, 75±5% RH and 16L : 8D). The leaf disc method was used to study acute toxicity, the effect of LC10, LC30, and LC50 on the feeding efficiency of 4th instar larva, and biochemical indices. The essential oil doses of LC10, LC30 and LC50 were estimated to be 0.107%, 0.188% and 0.279% for T. vulgaris, and 0.67%, 1.173% and 1.728% for O. vulgare, respectively. The results showed that T. vulgaris was more toxic than O. vulgare. The essential oil sublethal dose LC30 affected the nutritional indices of 4th instar larvae of G. pyloalis. The essential oils reduced total protein, carbohydrate, and lipid. Some concentrations of essential oils changed the activity level of α-amylase, protease, lipase, general esterases, and glutathione S-transferase (GST) but others showed no effect on these enzymes. It was concluded that the used essential oil concentrations were both toxic to G. pyloalis and showed irreversible effects on key metabolic processes, therefore, the used essential oil concentrations may be considered as alternatives to the classic pest control agents.

The Matrix

In recent years, it has been confirmed that essential oils (EOs) exert antimicrobial activity as they are able to inhibit cell growth and inactivate microbial cells. The application of biopreservation strategies by means of EOs opens up interesting perspectives in the food industry, including meat production. The paper aims to evaluate the effects of <em>Thymus vulgaris</em> (red thyme) and <em>Caryophyllus aromaticus</em> (cloves) EOs on the development of the spoilage population of fresh pork packaged under modified atmosphere (MAP). In particular, the research was focused on <em>Brochothrix thermosphacta</em>, a specific spoilage microorganism of fresh meat packed in anaerobic conditions or under MAP. Amongst seven EOs, those that showed the highest antimicrobial activity on 5 <em>B. thermosphacta</em> strains <em>in vitro</em> were: cloves [minimum inhibitory concentration (MIC) 0.6-2.5 mg/mL], savory (MIC 2.5-5.0 mg/mL), and red thyme (MIC 2.5 to 20 mg/mL). Red thyme and cloves EOs were selected for meat treatment, by increasing the dose at 20 and 40 mg/mL respectively, to take into account the matrix effect that can reduce EO availability. In spite of the minor efficacy observed <em>in vitro</em>, 40 mg/mL red thyme EO strongly limited the growth of <em>B. thermosphacta</em> in pork samples up to day 6 of storage [below 3.0 Log colony forming unit (CFU)/g, starting from 2.0 Log CFU/g at time 0], and exerted an antimicrobial effect also on the aerobic mesophilic count. Good results were obtained also with 20 mg/mL red thyme EO. The control of <em>B. thermosphacta</em> growth through EOs encourages research on alternative methods for extending the shelf life of fresh meat under MAP.

Natural Additives

Herbs have been used as natural additives against chemical additives during the last few years, since the latter have been accused that can endanger consumers life. Oregano (Origanum vulgare ssp hirtum), thyme (Thymus vulgaris) and sage (Salvia officinalis) are three herbs that are found in Greece and their use as natural additives to foods have been investigated in recent years all over the world. Herbs are rich in phenols, which are principally characterized by a notable antimicrobial and antioxidative activity. The two main phenols of Oregano and thyme are carvacrol and thymol, which are in higher amounts than other compounds. The main phenolic compounds of sage are thusone and rosmanol. Other compounds found in lower amounts, like n-cymene (in Oregano and thyme) or a-terpineol (in sage) contribute in the antimicrobial and antioxidative activity of these herbs. Oregano, thyme and sage present an important antimicrobial activity against several pathogens of foods, such as Staphylococcus aureus, E. coli, E. coli 0157:H7, Salmonella typhimurium, Yersinia enterocolitica, Campylobacter jejuni or Listeria monocytogenes. The present herbs present also an important antifungal activity against fungi that can grow in foods like Aspergillus spp. or Candida spp., which can endanger consumers life. The antimicrobial and antioxidative activity of these herbs was verified either in vitro experiments or in foods. The dietary supplementation of Oregano and thyme essential oil to chicken and turkeys resulted in the oxidative stability of their meat during refrigerated and frozen storage.

Main Components

Natural antioxidants are becoming a major focus because natural food ingredients are safer than synthetic types. The aim of this study was to investigate the protective effects of Thymus vulgaris and Bunium persicum essential oils (EO) on the oxidation of virgin olive oil (VOO) during accelerated storage. The antioxidant activities of EOs were compared with those of α-tocopherol and BHT. GC/MS analyses revealed that thymol (28.50%), p-cymene (27.14%), carvacrol (18.36%), and γ-terpinene (4.97%) are the main components of T. vulgaris EO, while cuminaldehyde (32.81%), γ-terpinene (16.02%) and p-cymene (14.07%) are the main components of B. persicum EO. Both EOs provided protection for the VOO, inhibiting the formation of primary and secondary oxidation products although T. vulgaris EO showed greater protection against the oxidation process than B. persicum EO. The effect of T. vulgaris essential oil on the oxidation inhibition of VOO was similar to that of BHT. α-Tocopherol showed no measurable effect on improving the oxidative stability of VOO. This study suggests that T. vulgaris and B. persicum EOs can be used to improve the oxidative stability of VOO.
