“…MDA content is an indicator of membrane lipid peroxidation in cells, reflecting the degree of peroxidation and cell membrane damage [31]. Notably, ergosterol is a major sterol component of the fungal cell membrane and has an important role in maintaining the integrity of the cell membrane; a decrease in ergosterol content could lead to the destruction of the cell membrane [26,32].…”

Fusarium wilt, mainly caused by Fusarium oxysporum, affects ginger yield and quality worldwide. To explore a safe and sustainable method of preventing and controlling Fusarium wilt, the inhibitory effects of eugenol on F. oxysporum FOX-1 were analysed in this study. The results showed that eugenol inhibited the reproductive and vegetative growth of F. oxysporum FOX-1 in vitro. Microscopic observations revealed that eugenol disrupted the hyphal morphology of F. oxysporum. In addition, eugenol destroyed the cell membrane integrity of the pathogenic fungi, resulting in the leakage of F. oxysporum FOX-1 intercellular contents, including electrolytes, soluble proteins, nucleic acids, and malonydialdehyde. Results of an in vivo inoculation test showed that eugenol exerted a strong inhibitory effect on Fusarium wilt in ginger seedlings. In summary, eugenol had an inhibitory effect on the growth of F. oxysporum FOX-1 and controlled Fusarium wilt in ginger seedlings. These findings provide a foundation for future development of botanical antifungal agents to manage Fusarium wilt.

“…In addition, it is reported that compared to other plant essential oil components, carvacrol exhibits superior postharvest disease inhibitory activity. In a recent study by MI et al [23], it was found that the growth of A. alternata was significantly inhibited after treatment with carvacrol, ultimately improving the storage quality parameters of kiwifruit. Due to the harmful effects of high concentrations of carvacrol on fruits, it is not suitable to choose high concentrations in practical applications [24].…”

In this study, we isolated and identified pathogenic fungi from the naturally occurring fruits of red grapes, studied their biological characteristics, screened fifteen essential oil components to find the best natural antibacterial agent with the strongest inhibitory effect, and then compared the incidence of postharvest diseases and storage potential of red grapes treated with two concentrations (0.5 EC50/EC50) of essential oil components (inoculated with pathogenic fungi) during storage for 12 d at room temperature. In our research, Alternaria alternata was the primary pathogenic fungus of red grapes. Specifically, red grapes became infected which caused diseases, regardless of whether they were inoculated with Alternaria alternata in an injured or uninjured state. Our findings demonstrated that the following conditions were ideal for Alternaria alternata mycelial development and spore germination: BSA medium, D-maltose, ammonium nitrate, 28 °C, pH 6, and exposure to light. For the best Alternaria alternata spore production, OA medium, mannitol, urea, 34 °C, pH 9, and dark conditions were advised. Furthermore, with an EC50 value of 36.71 μg/mL, carvacrol demonstrated the highest inhibitory impact on Alternaria alternata among the 15 components of essential oils. In the meantime, treatment with EC50 concentration of carvacrol was found to be more effective than 0.5 EC50 concentration for controlling Alternaria alternata-induced decay disease of red grapes. The fruits exhibited remarkable improvements in the activity of defense-related enzymes, preservation of the greatest hardness and total soluble solids content, reduction in membrane lipid peroxidation in the peel, and preservation of the structural integrity of peel cells. Consequently, carvacrol was able to prevent the Alternaria alternata infestation disease that affects red grapes, and its EC50 concentration produced the greatest outcomes.

“…Carvacrol is the main component of oregano and thyme essential oils, which has high antimicrobial and antioxidant activity and was approved by the FDA for use as a GRAS (Generally Recognized as Safe) food additives (Bhavaniramya et al, 2019;Burt, 2004). It is also frequently used as a avoring agent or antimicrobial agent in a variety of products, which could provide broad activity against bacteria, yeasts and fungi (Mi et al, 2023;Zhou et al, 2019). However, the highly volatile and poor water solubility of carvacrol potentially limit its application in food products (de Souza et al, 2022; Guo et al, 2023).…”

Carvacrol essential oil has broad-spectrum antibacterial properties, but the essential oil is volatile and unstable for long term storage and using. In order to improve the relevant properties of carvacrol, in the present study, carvacrol was encapsulated with β-cyclodextrin (β-CD) using the saturated aqueous solution method and response surface analysis was carried out, which gave a high encapsulation rate (63.58%). The success encapsulation of carvacrol was confirmed by scanning electron microscopy, Fourier infrared spectroscopy, X-ray diffraction and thermogravimetric analysis. The release performance of the encapsulants was also tested at different temperature and humidity levels. In addition, Polyethylene glycol (PEG) composite carvacrol-inclusive fresh-keeping paper prepared by these anhydrous conditions showed high antibacterial activity against Streptomyces fructus Monilinia fructicola, the main pathogen of peaches. Also, PEG was used to form the film in the anhydrous condition with the inclusion compound and ethylene inhibitor 1-methylcyclopropene (1-MCP) to obtain the film coated paper, and its effect on postharvest preservation quality of peach was studied. The results showed that PEG + Carvacrol-β-CD + 1-MCP-α-CD inclusion complexes (ICs) effectively prolonged the storage time and improved the fruit quality and enzyme activity of peach. This study provides a solution for the preparation of controlled-release coated paper with essential oils and 1-MCP bioactives to extend the shelf life of fruits and vegetables.
