“…5 This is due to increasing concerns regarding the environmental impacts of synthetic pesticides, as well as stricter controls on their use and the appearance of fungicide-resistant strains. 1,6 Given the importance of developing new biopesticides and investigating their spectra of action, a recent survey showed promising results with the allelopathic plant Conyza canadensis (L.) Cronquist, which belongs to the Asteraceae family and is popularly known as horseweed. 7 This plant is a potential source of bioactive compounds 8 and several studies have reported the fungitoxic effects of its essential oils, [9][10][11] although the compounds responsible for such activity were not identified.…”

Synthetic fungicides are a common treatment for post-harvest diseases in fruits, although demand is increasing for alternatives such as biopesticides. The aim of this work was to investigate the presence of naturally occurring antifungal compounds in Brazilian specimens of the weed Conyza canadensis. Two compounds [(4Z)-lachnophyllum lactone and (4Z,8Z)-matricaria lactone] were isolated and their antifungal activities were evaluated against eight postharvest disease fungi. Aspergillus niger, Cladosporium sp., and Penicillium digitatum proved susceptible to the treatment (minimum inhibitory concentrations varying from 32 to 64 µg mL -1 ). These fungi are common postharvest pathogens of fruits and vegetables, causing rots and secreting mycotoxins. A green and sustainable extraction method employing pressurized hot water was developed and optimized (100 °C, 4 × 1 min cycles). Yields of 1.46 and 0.24 mg g -1 were obtained for (4Z)-lachnophyllum lactone and (4Z,8Z)-matricaria lactone, respectively. The extract could be applied directly to fruits and vegetables in postharvest treatments.

“…Further, these polymers have been mixed with essential oils from different sources (Sivakumar & Bautista-Baños, 2014). These composite films reduce and even eliminate the presence of pathogenic microorganisms; furthermore, these applications increase the shelf life of fruits and vegetables acting as a semipermeable covering, partially modifying the micro-atmosphere of the fruit and delay ripening (Dotto et al, 2015).…”

Chitosan composite films: physicochemical characterization and their use as coating in papaya Maradol stored at room temperature

et al. 2017

The main objectives of this study were; first formulate and evaluate some properties of chitosan composite films enriched with essential oils of cinnamon, thyme, clove, and lime alone or in combination; and second select the most appropriate formulation and evaluate their effect on physiological properties and fungal incidence of papaya Maradol stored at environmental tropical conditions. Breaking strength, thickness, color, moisture, water vapor permeability, solubility and water sorption of films were measured. Furthermore, in vitro activity was evaluated against Colletotrichum gloeosporioides Penz. Using multivariate analysis and based on the most desirable characteristics (low water sorption values, water vapor permeability, solubility, and greater inhibition of C. gloeosporioides), three formulations of films were used lately for coated fruit of papaya Maradol and stored at 28 ± 2 °C and 85 % RH. Two control treatments were included: one uncoated and other treated with Mancozeb® fungicide. At six days of storage, the fruit of both control treatments showed evident signs of ripening; contrary to the treatments wherein fruit were coated, and had low respiration, other attributes as firmness, little change in the external color of the fruit were manifested. Similarly, the use of composite films reduced the fungus C. gloeosporioides by 30-50 %. The use of film enriched with essential oil of 1 % cinnamon- 1 % thyme improved the characteristics of fruit quality, increased shelf life and reduced by 50 % the incidence of fungus in papaya Maradol stored under humid tropic environmental conditions. This coating can be an alternative to potentially reduce the need for cold storage during postharvest handling.

“…Currently, research has been focused on the use of edible films due to their safety regarding consumption and friendly relation with the environment, and coating materials being used currently include polysaccharides (cellulose derivatives, starch, chitin, and gums), proteins (soy, milk, gelatin, corn zein, and gluten), and lipids (oils, waxes, and resins) [9]. Among them, carboxymethyl cellulose (CMC) and starch (S) are the most widespread and economic biomaterials.…”

e aim of this work was to evaluate the e ect of pH and Mexican oregano essential oil (MOEO) added to carboxymethyl cellulose (CMC) and starch (S) edible lms on Listeria monocytogenes and Staphylococcus aureus. CMC and S edible lms were formulated with di erent concentrations (0%, 0.25%, 0.50%, 0.75%, and 1%) of MOEO at di erent pH (5, 6, or 7). Antimicrobial assay was performed. Inhibition curves were tted to the Fermi model. Signi cant di erences (p < 0.05) were found in t c (time to reduce 50% of microbial population) and a (slope of the curve around t c ), being lower at acidic pH. For L. monocytogenes, CMC lms exhibited a higher antimicrobial e ectiveness (0.50% of MOEO) compared to S lms which need a higher concentration of MOEO (0.75%). S. aureus was inhibited with CMC lms at 0.50% MOEO and pH 5 and 6. Microbial modeling has allowed estimating key intrinsic factors as pH and MOEO concentration with the synergistic e ect against two important food-borne pathogens.
