The goal of this study is to evaluate the effects of rosemary, salvia, oregano and clove oils at volume fractions of 1000, 750, 500, 250, 100, 50, 26, 10 and 5 µL/mL (100, 75, 50, 25, 10, 5, 3, 1 and 0.5%) on the growth of contaminating fungi in salami. The effect of the oils against fungal growth was indicated by zones of inhibition. Rosemary oil showed an inhibition zone of 9.6 mm only at the maximal volume fraction (1000 µL/mL). Salvia oil showed inhibition zones of 12.2, 11.2 and 10.5 mm only at the three highest fractions tested. Based on the inhibition zones, clove oil at 125 and 250 µL/mL, oregano oil at 250 and 500 µL/mL and a mixture (1:1 by volume) of the two oils at 100 µL/mL were selected to be applied to the surface of salamis. A significant reduction of fungal growth in all of the oil-treated samples was confirmed by visual inspection. A sensory analysis revealed that the samples treated with 125 µL/mL of clove oil or 100 µL/mL of a mixture of oregano and clove oil showed no significant flavour differences compared with the control. Carvacrol and eugenol were the principal compounds in oregano and clove oils, respectively, and were most likely responsible for the antifungal activity.

In vitro tests were conducted to characterize the host-mediated responses of chickens to Clove Essential Oil (CEO) and Oregano Essential Oil (OEO). Chicken macrophage cells (CMCs), chicken intestinal epithelial cells (IECs), quail muscle cells (QMCs), and chicken embryonic muscle cells (EMCs) were utilized in these assays. EMCs were collected from the 13-day-old embryo during egg incubation and all cell lines were seeded at 2 × 10/mL in a 24-well plate.

The early post-hatching phase remains to be one of the most vulnerable phases in broiler production. Some essential oils have been reported to improve gut health and growth in broiler chickens when applied to post-hatching diets. However, in-feed applications are unable to prevent the health challenges observed immediately after hatching.

The preservation of fish and seafood represents a significant challenge for the food industry due to these products' high susceptibility to microbial spoilage. Essential oils (EOs), classified as Generally Recognized as Safe (GRAS), have become a natural alternative to synthetic preservatives due to their antimicrobial and antioxidant properties. This review aims to analyze the specific potential of EOs in extending the shelf life of fish and seafood products, offering a natural and effective preservation solution.

Numerous health benefits have been attributed in the last decades to the regular consumption of fruits, vegetables, herbs and spices, along with honey, in a balanced diet. In this context, the aim of the present review was to provide the literature with the most relevant studies focusing on the determination protocols of these polyphenols and other reducing agents in selected fruits (orange, lemon, grapefruit, prunus, apricot, peach, plum, sweet cherry), spices (oregano, cinnamon, clove, saffron, turmeric) and honey of different botanical origin (nectar or honeydew). In addition, the content and the extraction methods of these compounds, along with their metabolic pathway, have been critically evaluated and discussed.

This study evaluated protective effects of clove (SEO), thyme white (TEO), oregano (OEO), and caraway (CEO) essential oils (EOs), and their binary mixtures, in a zebrafish fetal alcohol spectrum disorder model. Furthermore, folic acid (FA) was used for comparison as it had previously shown protection against ethanol (EtOH)-induced defects. The co-exposure of zebrafish embryos to EtOH (150 mM) and FA (75 μM) or EOs and their binary mixtures (0.
