Red propolis has antioxidant and antimicrobial properties, which means it great potential for application in the food sector.However, its low solubility water may limit this area.Crude red can be used emulsified form, order to protect compounds allow their dispersion an aqueous system, as case of biopolymeric active films packaging.Thus, objective thesis was development based on gelatin or soy protein isolate incorporated with crude encapsulated oil-in-water (O/W) emulsions using different emulsifiers.To select best emulsions, a Box-Behnken experimental design used, variables studied being concentration emulsifier (Tween 80 saponin), PGPR (polyglycerol polyricinoleate) number cycles.The response were stability index, average droplet diameter polydispersity index.Sodium caseinate also varying produce emulsion.The selected characterized regarding color, pH, rheological behavior, activity.Active produced by incorporating emulsions.These microstructure, thermal mechanical optical activity.The results showed that had effect size encapsulating Tween capable producing emulsion stability.The behavior Newtonian fluid, activity against gram positive bacteria.The incorporation into films, isolate, presence oil droplets surface internally porous.The contact angle, gloss decreased emulsions.The caused increase barrier UV/visible light more resistant extensible gelatin, except film sodium caseinate.As elongation at break, but did not affect resistance.Although bacteria, exhibit formation inhibition halo.The activity, regardless production emulsions.Thus, observed packaging foods subject oxidation.

To fight the global epidemic of drug-resistant bacteria, essential oils have gained increasing attention as a new source antibiotics. The antimicrobial activity Monarda didyma (MDEO) for Carbapenem-resistant Klebsiella pneumoniae (CRKP) strains were determined by agar disc diffusion assay and broth microdilution assay. further understand MDEO efficacy, time-growth curve was performed. biofilm formation CRKP crystalline violet staining method, additionally, changes in intracellular Adenosine triphosphate (ATP), protein, Alkaline phosphatase (AKP) activities, membrane integrity investigated to assess influence on cell damage. Finally, activities key enzymes tricarboxylic acid (TCA) pathways pentose phosphate (PPP) examined determine effect respiratory metabolism CRKP. This study presents antibacterial mechanism against with minimum inhibitory concentration (MIC) bactericidal (MBC) 1.25 mg/ml. time-kill kinetics approach evident at 2 h compared control its MIC 2MIC. Surface electron microscopic ATP studies provided evidence multi-target action could inhibit formation. also cause irreversible damage membrane, resulting leakage biological macromolecules (protein, ATP) reduction activities. affected metabolism, such PPP TCA pathways. reduce (Glucose-6-phosphate dehydrogenase, citrate synthase, isocitrate α-ketoglutarate dehydrogenase) exert effects These results suggest can CRKP, potential mechanisms including inhibition formation, structure energy metabolism.

Abstract Mentha haplocalyx essential oil (MEO) has demonstrated inhibitory effects on Fusarium oxysporum . Despite its environmentally friendly properties as a natural product, the limited water solubility of MEO restricts practical application in field. The use nanoemulsion can improve bioavailability and provide an eco-friendly approach to prevent control Panax notoginseng root rot. In this study, Tween 80 anhydrous ethanol (at mass ratio 3) were selected carriers, ultrasonic method was utilized produce (MNEO) with average particle size 26.07 nm. Compared MTEO (MEO dissolved aqueous solution 2% DMSO 0.1% 80), MNEO exhibited superior inhibition against F. terms spore germination hyphal growth. Transcriptomics metabolomics results revealed that after treatment, expression levels certain genes related glycolysis/gluconeogenesis, starch sucrose metabolism significantly suppressed along accumulation metabolites, leading energy disorder growth stagnation contrast, effect from treatment less pronounced. Furthermore, also meiosis, ribosome function, biogenesis process. These findings suggest possesses enhanced stability antifungal activity, which effectively hinders through inducing disorder, meiotic stagnation, well dysfunction, thus indicating potential for development green pesticide prevention P. rot caused by F.oxyosporum
