The oil is prone to oxidation, which negatively affects its properties and performance. In this study, six different essential oils obtained from herbs and spices (Sage, Laurel, Basil, Rosemary, Thyme, Oregano) were added to pharmaceutical and technical grade white mineral oils at 0.1 - 0.8 % (w/w) concentrations. Light, heat and air were applied to induce and accelerate oxidation. The total acid number, viscosity, and DPPH radical scavenging activity of the oils were measured in addition to the TGA and DSC tests to evaluate the anti-oxidation performance of the additives. The results showed that combined heat and oxygen treatment was the most effective of the three conditions tested to cause oxidation. The highest DPPH scavenging activities were obtained with oregano and thyme essential oils (up to 59% and 54% DPPH increase, respectively) and DPPH% activity increased linearly with increasing essential oil concentration. Thermal analyses, total acid number and viscosity change data also suggested the essential oils of Thyme, Oregano and Laurel as the best antioxidant additives to be used in white oils.","PeriodicalId":16626,"journal":{"name":"Journal of oleo science","volume":"74 7","pages":"633-645"},"PeriodicalIF":1.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144553725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, emulsifier-free, submicron-sized, monodisperse RBW particles were prepared via melt emulsification using a combination of a high-HLB emulsifier-decaglycerin stearate or Tween 20-and a low-HLB emulsifier-glyceryl stearate or Span 20. High dispersibility was achieved due to the zeta-potential generated by the surrounding surfactants, resulting in monodispersed submicron-sized RBW particles. Surface cleaning with ethanol effectively removed surface-adsorbed emulsifiers, yielding emulsion-free RBW particles. Due to the hydrophobic nature of the wax particles, high solvent repellencies were observed, along with the formation of colloidal assemblies such as liquid marbles and W/O Pickering emulsions using cosmetics-applicable liquids. Based on X-ray diffraction analysis and differential scanning calorimetry, RBW was identified as a promising candidate for emulsifier-free submicron-sized particles due to its high crystallinity, which facilitates the effective elimination of emulsifiers.","PeriodicalId":16626,"journal":{"name":"Journal of oleo science","volume":"74 7","pages":"567-576"},"PeriodicalIF":1.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144553754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we investigated aqueous systems of the bio-based surfactants alkyl β-d-galactosides (CnGals, where n represents the chain length; n = 6, 8, 10, 11, and 12). First, we confirmed that CnGals aqueous systems formed micelle solutions upon heating and hydrogel upon cooling. In particular, decyl β-d-galactoside (C10Gal) exhibited a homogeneous fiber morphology at low concentrations (0.1 wt.%), whereas larger n values afforded an inhomogeneous solid matrix and smaller n values required higher concentrations or did not form a fiber structure. In addition, the C10Gal micelles solubilized curcuminoid dyes such as demethoxycurcumin and curcumin and allowed preparing luminescent fibers upon cooling the solution. The removal of water afforded the corresponding C10Gal-dye solid composite with a high luminescence quantum yield. Powder X-ray diffraction and differential thermal analysis suggested the formation of a stable adduct or cocrystal with a unique interaction between the curcuminoid dyes and C10Gal. Therefore, we successfully prepared an environmentally friendly, highly luminescent organic solid via micelle-to-fiber transition of an environmentally friendly surfactant induced by a mild temperature change.","PeriodicalId":16626,"journal":{"name":"Journal of oleo science","volume":"74 8","pages":"689-699"},"PeriodicalIF":1.8,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144775669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eighteen CAB were identified up to species level using 16S rRNA gene sequencing, viz., Klebsiella pneumoniae, Staphylococcus aureus, and Pseudomonas aeruginosa. T. ammi essential oil and T. foenum-graecum methanolic extract combination exhibited the highest antibacterial activity (ZOI; 32.0) against S. aureus.

All plant extracts demonstrated more than 80% antibiofilm and biofilm inhibition activity. A concentrationdependent increase was observed with plant extracts against CAB during antibacterial, antibiofilm, and biofilm inhibition activities.

Most food factories clean and sanitize equipment daily after production using detergents containing benzalkonium chloride (BAC). However, in factories that produce oil and fat-rich foods, it has been discovered that microbes can persist on production equipment. Insufficient cleaning protocols may result in secondary contamination of the final products. Unfortunately, there are limited cleaning agents available that are effective in sterilizing microbes in the presence of oil. Moreover, there is a lack of research on the bactericidal mechanisms and bacterial dynamics in oily environments. In this study, we aimed to reduce bacterial contamination on equipment in such factories by hypothesizing that oil diminishes BAC's bactericidal activity. We conducted lab-scale experiments simulating actual factory conditions to examine the effects of oil on BAC's efficacy. Additionally, we investigated the effect of nonionic surfactants, which are known to enhance BAC's bactericidal activity in oil-free conditions, in the presence of oil. The results showed that BAC's bactericidal activity was significantly reduced in the presence of oil. However, the activity was restored by adding an appropriate amount of secondary alcohol ethoxylate (sec-AE). Microscopic observations revealed that bacteria tended to accumulate at the water/oil interface, suggesting that the oil interface might inhibit BAC from effectively attacking the bacteria. The addition of sec-AE appeared to disperse the bacteria into the water layer, thus restoring BAC's bactericidal activity in the presence of oil. These findings are crucial for improving daily cleaning and sterilization processes in food factories operating in high-oil environments to prevent secondary contamination and enhance food safety.","PeriodicalId":16626,"journal":{"name":"Journal of oleo science","volume":"74 2","pages":"173-185"},"PeriodicalIF":1.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143066155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, delayed cutaneous wound healing, severe adverse skin reactions such as pain, burns, irritation, and unsatisfactory storage stability have limited its clinical use as it is known that the performance of ozonized sunflower oil is reflected by core indicators such as iodine value (IV), peroxide value (PV), and acid value (AV). Aiming to improve the above characteristics, ozone oxidation conditions such as the oil water content of raw materials, stirring speed, and ozonized time were successfully optimized, and the optimized conditions were 5%, 300 rpm, and 6 h, respectively. Additionally, the UHPLC-Q-Exactive Orbitrap MS was used to identify the compounds of sunflower oil and ozonation sunflower oil, and 10 fatty acids were successfully identified. The results clearly indicated that the ozonized sunflower oil prepared under optimized ozonation conditions achieved a high degree of ozonation (II) and a satisfactory PV/AV ratio. These optimized conditions further proved to be valuable in improving not only the storage stability of ozonized sunflower oil for up to six months but also in ensuring its remarkable antimicrobial effects on Staphylococcus aureus and Candida albicans, with a PV of 165.75 mmol/kg achieving a 100% antibacterial efficacy.","PeriodicalId":16626,"journal":{"name":"Journal of oleo science","volume":"74 7","pages":"587-598"},"PeriodicalIF":1.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144553728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
