The chemical composition of essential oils (EOs) from dried and fresh flowers of Lavandula angustifolia L. (lavender), named LA 2019 and LA 2020, respectively, grown in central Italy was analyzed and compared by GC and GC-MS. For both samples, 61 compounds were identified, corresponding to 97.9% and 98.1% of the total essential oils. Explorative data analysis, performed to compare the statistical composition of the samples, resulted in a high level of global similarity (around 93%). The compositions of both samples were characterized by 10 major compounds, with a predominance of Linalool (35.3–36.0%), Borneol (15.6–19.4%) and 1,8-Cineole (11.0–9.0%). The in vitro antibacterial activity assay by disk diffusion tests against Bacillus subtilis PY79 and Escherichia coli DH5α showed inhibition of growth in both indicator strains. In addition, plate counts revealed a bactericidal effect on E. coli, which was particularly noticeable when using oil from the fresh lavender flowers at the highest concentrations. An in vitro antifungal assay showed that the EOs inhibited the growth of Sclerotium rolfsii, a phytopathogenic fungus that causes post-harvest diseases in many fruits and vegetables. The antioxidant activity was also assessed using the ABTS free radical scavenging assay, which showed a different antioxidant activity in both EOs. In addition, the potential application of EOs as a green method to control biodeterioration phenomena on an artistic wood painting (XIX century) was evaluated.

And Performance

This paper is concerned with the preparation of cellulose packaging films with high oxygen permeability. The films were prepared from cotton pulp and wood pulp by the cast-wiped method using N-methymorpholine-N-oxide (NMMO) as a solvent. The effects of processing parameters on the structure and performance of cellulose films were also studied. The results show that for optimum processing of the films cotton pulp was the preferred raw material, the optimum pulp concentration in the casting solution was 5%, and the optimum temperature for the coagulation bath was 40°C. Using the above process conditions resulted in packaging films with high oxygen permeability making them suitable for use in packaging fruits and vegetables.

Current Concerns

The barrier properties of the cellulose packaging films are current concerns for the fields of fruits and vegetables fresh-keeping packaging. One such porous films commonly used the pore formers as hole-forming materials whereas the compatibility and dispersity were not better with the cellulose solutions. In this study, the porous cellulose packaging films were prepared with natural broad-leaved pulp and LiCl/DMAc with different types of coagulation baths. The effects of methanol, ethanol, isopropanol, LiCl/DMAc and deionized water coagulation baths on the physical structures, oxygen and water vapor permeabilities and mechanical properties of the films were measured. Based on the scanning electron microscpy (SEM) observation, the cross section was loose when used the alcohol coagulations, especially the films with ethanol coagulation showed dactylopores. It was also found that the oxygen permeability had obviously improving with the effect of ethanol, which compared with water vapor permeability of the films. The porous cellulose packaging films had better mechanical properties and up to 12.7MPa which would satisfy the usage in packaging.

This study was designed to examine in vitro antibacterial activities of essential oils extracted from 53 aromatic plants of Gorakhpur Division (UP, INDIA) for the control of two phytopathogenic bacteria namely Erwinia herbicola and Pseudomonas putida causing several post-harvest diseases in fruits and vegetables. Out of 53 oils screened, 8 oils such as Chenopodium ambrosioides, Citrus aurantium, Clausena pentaphylla, Hyptis suaveolens, Lippia alba, Mentha arvensis, Ocimum sanctum and Vitex negundo completely inhibited the growth of test bacteria. Furthermore MIC & MBC values of C. ambrosioides oil were least for Erw. herbicola (0.25 & 2.0 ?l/ml) and Ps. putida (0.12 & 1.0 ?l/ml) respectively than other 7 oils as well as Agromycin and Streptomycin drugs used in current study. GC and GC-MS analysis of Chenopodium oil revealed presence of 125 major and minor compounds, out of them, 14 compounds were recognized. The findings concluded that Chenopodium oil may be regarded as safe antibacterial agent for the management of post-harvest diseases of fruits and vegetables.
