“…The structural surface and cross-sectional morphologies of SRC-control, SRC + G, and SRG + G (Jiménez et al, 2012;Nouri et al, 2018). Besides that, the amount of lipid can increase the collision frequency between droplets and coalescence rate in the polymeric matrix (Hafsa et al, 2016). The results are in agreement with the findings reported by Nouri et al (2018) where SRC + G films.…”

Semi‐refined carrageenan (SRC) film plasticized with glycerol and incorporated with α‐tocopherol was prepared for food packaging application. Functional characterization, thermal stability, and microstructure of SRC‐based films were analyzed. The effects of antioxidant α‐tocopherol from SRC‐based film were studied based on thiobarbituric acid‐reactive substance assay, metmyoglobin assay, and pH value in food model (meat patties) for 12 days of storage. The development of lipid oxidation was delayed in the meat patties wrapped with antioxidant films during the storage with the final value of 0.68–0.37 mg malondialdehyde/kg sample. A less than 50% brown color development (metmyoglobin) of the meat patties wrapped with antioxidant film was observed in the first nine days of storage. Hence, the incorporation of α‐tocopherol into the SRC‐based film could be an alternative way to prolong the shelf life of food product, reducing the use of synthetic preservative directly into food product. Practical applications Recent strategy on the development of biodegradable film for food packaging is important as an alternative to the petrochemical‐derived plastic that is harmful to the environment. SRC is one of the potential biopolymers that has the ability to form a strong gel and provides efficient barrier against gas, lipids, and oils, and addition of plasticizer glycerol into SRC enhanced mechanical and barrier properties of the films. The present study showed the potential of α‐tocopherol within the SRC film plasticized with glycerol as active packaging on the film characteristics and increased the shelf life of meat patties. Hence, the active packaging film developed is not only contributes to reduce plastic waste discharged to environment but can be a potential substitute of synthetic preservative in food.

“…In our study, Mentha puligium, T. vulgaris and E. globulus oils exhibited strong activity against the selected bacterial strain. Several studies [24][25][26] have shown that mentha, thym and eucalypus had strong and consistent inhibitory effects against various pathogens. The antibacterial activity has been attributed to the presence of some active constituents in the oils.…”

“…Several studies have already demonstrated the antimicrobial activity of Eucalyptus compounds in different domains of life sciences [37,38]. Indeed, E. globulus is an antiseptic of the respiratory tract, expectorant, analgesic, decongestant, hypoglycemic, a detoxifying action of diphtheria toxins and Tetanus, anti-inflammatory, improves respiratory function tests, mucolytic, bronchial antispasmodic, febrifuge, very pronounced bronchopulmonary tropism, drying in high proportion [26,39]. Also, the 1.8-cineola contained in Eucalyptus has been shown to be effective in reducing the dose of corticosteroids used by asthma sufferers [40] and to combat the common cold [41,42].…”

To investigate biological control mains against phytopathogenic agent Pseudomonas syringae pv. tomato DC3000, responsible for bacterial speck, tests on the antibacterial activity of six essential oils were carried out. The essential oils, obtained by hydro distillation, was analyzed by gas chromatography (GC). The determination of the antibacterial activity of the essential oils carried out in-vitro using the well diffusion, micro atmosphere methods and the determination of MIC and CMB. Only essential oils of Cedrus atlantica had a negative activity against the bacterial strain. However, the overall results of this study suggested that Mintha pulegium, Thym vulgaris, Eucalyptus globulus essential oils had potential as a bio-pesticide for the control of bacterial speck disease of tomato. genetics and biotechnology (PGMB) [5]. This strain is characterized by the production of an endotoxin (pyoverdine) [10] and by its multiple resistance to antibiotics (rifampicin) [4]. The P. syringae pv. tomato cultures were grown on King's B and LB with rifampicin (50 g/ml) agar plates for strain verification.

“…The essential oil extracted from the leaves of Eucalyptus globulus Labill is known to be a rich source of traditional medicines with a variety of biological activities [10] It is widely used to treat pulmonary tuberculosis, diabetes [11][12] , asthma and also used as disinfectant [13][14] , antioxidant agent and antiseptic agent especially in the treatment of upper respiratory tract infections and certain skin diseases [15][16] asthma. Antibacterial and antifungal properties of Eucalyptus extract and oil are also reported by some authors.…”

The aim of this study was to evaluate the phytotoxic potential of 100% alcoholic crude extract as well as petroleum ether fraction of young leaves of Eucalyptus globulus on seed germination and seedling growth of tomato (Solanum lycopersicon) as well as to determine the growth bioassay. The crude extract was prepared by cold extraction method and petroleum ether fraction was prepared by hot extraction method with soxhlet assembly. The extraction was carried out with young healthy leaves (in powder form) and organic solvent. 5, 10, 15, 20 and 25 mg/ml concentrations are used for phytotoxicity assay.Phytotoxicity was done by standard blotter method. The Result showed that 5, 10 and 15 mg/ml concentration of extract was non phytotoxicand were further used for in vivo experiments using chambered plastic tray. The phytotoxic potential of the crude as well as partially purified extract of leaves of Eucalyptus globulus varied according to concentration and it is called concentration depended inhibitory effect. 25 mg/ml concentration had the greatest inhibitory effect on the seed germination that is 35% in crude extract and 30% in a partially purified extract. Similarly, 25 mg/ml concentration observed to be toxic against a seedling growth of tomato and indicating that the compound responsible for the phytotoxic residue within these extracts. The major cause of performing this assay is related to develop a safer and herbal formulation using this plant extracts to control plant pathogenic fungi.
