“…Regarding CT against Listeria monocytogenes various studies investigated the impact of CT on listeria growth and cell damage in Listeria innocua and Listeria monocytogenes, revealing that CT's antilisterial activity depends on the composition of lemongrass EO, while it is mentioned that may there is a disruption to the fatty acid and peptidoglycan biosynthesis (Silva-Angulo et al, 2015;Lu et al, 2018;Budiati et al, 2020). Another study evaluated the antimicrobial activity of six plant EOs against Listeria monocytogenes.…”

Introduction: Nowadays, the bioeconomy and sustainability trends drive the food sector to replace chemical preservatives with bioactive compounds recovered from biomass such as essential oils (EOs) and their derivatives. Moreover, nanotechnology trend drives food sector in the nanoencapsulation of such bioactive compounds in novel edible formulations such as nanoemulsions to enhance their controlled release properties, their bioactivity and their biocompatibility.Methods: In this study the development and characterization of novel casein/lecithin (CSN/LCN) based nanoemulsions (NEs) with carvacrol (CV), cinnamaldehyde (CI), citral (CT), and eugenol (EG) as nanoencapsulated oil phase is presented as well as the application of such NEs as active coatings for the preservation of fresh pork tenderloin.Results and discussion: DLS measurements as well as TEM images showed an average particle size distribution of 20–40 nm for all obtained NEs, while z-potential results indicate their physicochemical stability. All the obtained NEs needed at least 5 times less amount of EOs derivatives to scavenge 50% of radicals and demonstrated a higher antibacterial activity against Escherichia coli and Listeria monocytogenes compared to free EOs derivatives. Pork fresh tenderloin meat treated with NEs demonstrated 30% higher efficacy in obtained lipid oxidation values than uncoated pork meat samples and 12% higher efficacy in obtained lipid oxidation values than pork meat samples treated with EOs derivatives. From a microbiological point of view NEs manage to extend pork tenderloin meat shelf life by 6 days compared to uncoated pork tenderloin meat and by 3 days compared to tenderloin pork meat coated with free EOs derivatives. Lab* colorimetry analysis as well as sensory analysis revealed that such edible CSN/LCN based NEs succeeded to preserve the texture, appearance, and color of pork tenderloin meat in higher acceptance limits compared to the corresponding characteristics of pork tenderloin meat coated with free EOs derivatives. Overall, the current study suggests novel CSN/LCN-based edible NEs as a promising technology that can be used as edible active coatings in the meat food industry.

Quality of edamame is the main requirement in the export trade, one of which is the skin color. The washing technique using ozone is expected to replace the use of chlorine in suppressing the microorganism contamination, pesticides residues and maintaining its quality. The ozonation time and ozone contact time variations were used in this study using continuous washing method. The ozonation time consisted of 0.10 and 15 minutes, while the washing contact time consisted of 0, 12, 18 and 24 minutes. Each variation was repeated 3 times to obtain an average result of changes in edamame skin color. The results of the research from the washing contact time and ozone time treatment gave identical results with the treatment without washing.

<p>The uses of essential oils in food and traditional medicine have attracted researchers worldwide for applications in the food, agriculture, cosmetics, and health industries. Among the sources of essential oils, the Alpinia genus produces galangal essential oils with great potential for use in many applications. This genus has been used for a long time in traditional medicine in some countries along with for food flavouring and spices. These essential oils from many plant organs of this genus contain several bioactive compounds with the typical phytochemical is 1,8-cineole or eucalyptol. Scientifically, the bioactivity of galangal essential oils has been proven. Some efforts have been conducted efficiently to extract the galangal essential oil, including using novel technologies-This article aims to review the Alpinia species bearing essential oils and their traditional uses, phytochemicals of galangal essential oils and their bioactivity, the methods of extraction, phytochemical profiles, stabilization, uses, and potential applications of these essential oils. This review also compares the bioactivity of galangal essential oils and their traditional uses and potential applications. The results of this review show that Alpinia species has a long history to use as traditional medicines in many countries. There is a closely correlation between traditional uses of galangal with the scientifically proven of health benefits. The studies on galangal essential oil bioactivity have deeply explored the capability as antioxidants, antimicrobial, anti-inflammatory, anticancer, anti-antiparasitic activities and cardiovascular impairment. The uses of galangal essential oils are correlated with their bioactivity. Galangal essential phytochemicals is characterized by the presence of 1,8-cineole. The 1,8-cineole is found in the parts of this plant organ with its concentration varies depending on the galangal species. Some studies indicates that the novel technologies produce higher yield than conventional method for essential oil extraction. The application of galangal essential oil has the constraint of high hydrophobicity, resulting in a poor solubility in the aqueous phase. Various techniques of emulsification are used to improve the its water miscibility. Galangal essential oils are potential to use in many sectors such as agriculture, food, pharmaceutical and personal care industries. The appropriate extraction method is still a challenge mainly to improve the yield along with preserving the bioactive compounds. Another challenge is exploring other <italic>Alpinia</italic> species, proof their health benefits, and exploring their potential uses in many sectors.</p>
