“…However, in this case, the oregano EO did not affect significantly the mechanical properties of the material when applicable in the concentrations ranged from 0.5% to 3.5%. The same results were reported by Zang et al 13 and Chun et al 37 when they used lower concentrations between 0.10% and 0.15% of EO as additive for active films.…”

The objective of this study was to develop active films containing oregano essential oil as a natural antifungal additive, aiming to increase hamburger buns' shelf life, safety and quality and improve their sensory characteristics. The films were produced with cellulose acetate using different concentrations of the natural additive (0.5%, 1.5%, 2.5% and 3.5%), and a control film without essential oil was also used for comparison. All analysed films showed an increase in tensile strength when compared to the control. The same behaviour was found for percentage of elongation. It also increased as the concentration of the natural additive increased, which may be considered a plasticizer. The active packaging containing the lowest concentration of the natural additive (0.5% oregano essential oil) increased the shelf life of hamburger buns from 12 to 27 days and contributed to the sensory quality of the buns, as justified with consumer's acceptability tests performed for flavour, aroma and overall impression. Consumers said they would probably buy the product if it was available on the market. Therefore, active antifungal packaging containing oregano essential oil as an active agent showed efficacy for application in hamburger bun preservation.

“…Fungi from soil also infect fallen seeds and are retained and spread to the aerial tissues as endophytes (U' Ren et al, 2009). Both culture-dependent and independent (metagenomic) analyses have revealed a rich diversity of bacterial and fungal endophytes in seed tissues (Shahzad et al, 2018;Kinge et al, 2019;Chun et al, 2021). It is believed that the seed microbiome (endophytes) is the first to be mobilized into a growing seedling, before it receives endophytes from the soil litter or through wind distribution (Mitter et al, 2017).…”

“…Of particular concern is the off-target effects of such treatment on the seed-borne microbiome, especially on fungi ( Karlsson et al, 2014 ; Prior et al, 2017 ). Both culture-dependent and independent methods have demonstrated that there is a rich diversity of fungi inside seeds ( Kinge et al, 2019 ; Chun et al, 2021 ). These fungal endophytes (FE) may have a role in early seedling growth and establishment.…”

Seed Treatment With Systemic Fungicides: Time for Review

et al. 2021

View full text Add to dashboard Cite

Pre-sowing seed treatment with systemic fungicides is a firmly entrenched practice for most agricultural crops worldwide. The treatment is intended to protect the crop against seed- and soil-borne diseases. In recent years, there is increasing evidence that fungicidal applications to manage diseases might inadvertently also affect non-target organisms, such as endophytes. Endophytes are ubiquitously present in plants and contribute to plant growth and development besides offering resistance to biotic and abiotic stresses. In seeds, endophytes may play a role in seed development, seed germination, seedling establishment and crop performance. In this paper, we review the recent literature on non-target effects of fungicidal applications on endophytic fungal community and discuss the possible consequences of indiscriminate seed treatment with systemic fungicide on seed endophytes. It is now well recognized that endophytes are ubiquitously present in all parts of the plant, including the seeds. They may be transmitted vertically from seed to seed as in many grasses and/or acquired horizontally from the soil and the environment. Though the origins and evolution of these organisms in plants are a matter of conjecture, numerous studies have shown that they symbiotically aid in plant growth and development, in nutrient acquisition as well in protecting the plants from abiotic and biotic stresses. Against this background, it is reasonable to assume that the use of systemic fungicides in seed treatment may not only affect the seed endophytes but also their attendant benefits to seedling growth and establishment. While there is evidence to indicate that fungicidal applications to manage plant diseases also affect foliar endophytes, there are only few studies that have documented the effect of seed treatment on seed-borne endophytes. Some of the convincing examples of the latter come from studies on the effect of fungicide application on rye grass seed endophyte AR37. More recently, experiments have shown that removal of seed endophytes by treatment with systemic fungicides leads to significant loss of seedling vigour and that such losses could be partially restored by enriching the seedlings with the lost endophytes. Put together, these studies reinforce the importance of seed endophytes to seedling growth and establishment and draw attention on how to trade the balance between the benefits of seed treatments and the direct and indirect costs incurred due to loss of endophytes. Among several approaches, use of reduced-risk fungicides and identifying fungicide-resistant endophytes are suggested to sustain the endophyte contribution to early seedling growth.

“…The quality of raw material is strongly associated with the quality of processed products. Sesame seeds, as an important food material, have been investigated in terms of their mineral nutrient contents [ 5 , 11 ], fatty acid composition [ 8 , 12 ], bacterial microbiome [ 13 ], phytochemicals [ 8 ], volatiles [ 12 ], and metabolite composition [ 2 ]. The motivations behind these previous studies were to achieve the discrimination of sesame seeds from different geographical origins [ 2 , 8 , 13 ], or to clarify the effect of agricultural practices or processing on sesame seeds [ 11 , 12 ].…”

The present study was conducted to clarify the differences in the multi-element, volatile organic compound, fatty acid, and metabolite fingerprints between black and white sesame seeds. A total of 53 chemical elements, 32 volatile flavor compounds, 40 fatty acids, and 283 metabolites were identified and evaluated in the two groups of sesame seeds. Univariate and multivariate statistics indicated a distinct separation between the two groups of sesame seeds. A panel of 16 chemical elements, 3 volatile compounds, 8 individual fatty acids, and 54 metabolites with p value < 0.05 and variable importance in projection score > 1 were selected as the most important discriminants for the two types of sesame seeds. Overall, these data reveal the influence of genotype on the chemical composition of sesame seeds. Our findings also demonstrate that the hybrid model of instrumental analysis and chemometrics is feasible for the discrimination of black and white sesame seeds.
