Thermoplastic starch (TPS) has emerged as an essential alternative to produce environmentally friendly packaging; however, retrogradation is a disadvantage that affects its shelf life. This study analyzed the co-plasticizing effect of isosorbide on mechanical, thermal, physicochemical, and microstructural properties films obtained by blown film extrusion from thermoplasticized with mixtures glycerol in different ratios (3:0, 2:1, 1:2, 0:3, respectively). The results showed higher...
Abstract. In the present research work, a composite with antibacterial properties against Staphylococcus aureus based on Nylon 6 and Polypropylene (PP) nonwoven fabric impregnated extracts of Rosmarinus officinalis is presented. The were obtained using ethanol as an extracting solvent getting yield percentages 14.67 % assisted by ultrasound frequency 60 kHz. characterization high-performance liquid chromatography coupled to mass, it was found that possible extract families such...
Abstract Coffee pulp is rich in bioactive compounds. Currently, the use of “green methodologies” being sought that promote cleaner, safer extraction protocols with lower energy consumption. The present study proposes polyphenolic compounds from coffee through methodologies such as ultrasound and microwave. Different conditions were evaluated, varying mass:volume ratio water:ethanol ratio. mineral content, amount total condensed polyphenols was determined well characterization extracts by...
Ultrasound energy is a green and economically viable alternative to conventional techniques for surface modification of materials. The main benefits this technique are the decrease processing time amount used. In work, graphene nanoplatelets were treated with organic acids under ultrasonic radiation 350 W at different times (30 60 min) aiming modify their functional acid groups improve adsorption uremic toxins. modified characterized by Fourier transform infrared spectroscopy (FT–IR),...
Moringa oleifera has been a focus of interest because the different properties (anticancer, antioxidant, etc.) that have attributed to this plant. However, most used methodology is soxhlet, which requires long periods reaction (18 hours), generating greater energy expenditure. Recently, green extraction technologies developed like ultrasound and microwaves, reducing time by up 97%. The objectives study were extract identify polyphenolic compounds present in aqueous hydro-alcoholic extracts...
Ultrasound and microwave assisted expedient synthesis of potential antibacterial compounds, 2-(anilino)-5- hydroxy-1,4-naphthoquinone derivatives 3a-c 5-hydroxybenzo[f]indole-4,9-dione 8a-c 10- hydroxybenzo[b]carbazole-6,11-dione 9a-c have been developed. For the preparation methods Room Temperature Synthesis (RTS), Conventional Heating (CHS) Assisted (UAS) were performed. In addition, (CS) Microwave (MAS) used for derivatives. UAS MAS showed best results are considered green alternatives...
Current trends in the use of new pigments natural origin have led to investigation novel technologies for obtaining them. The objectives this study were evaluate extraction process by microwave (MAE) and ultrasound (UAE) assisted techniques a treatment using simultaneously both (hybrid way) (HM-UE) from corn with different shades red (highly pigmented = RA, moderately RM poorly RB), determine color, content hydrolyzable polyphenols, condensed tannins, antioxidant potential DPPH, ABTS FRAP...
Exopolysaccharides (EPS) are biopolymers produced by many microorganisms, including some species of the genus Acetobacter, Bacillus, Fructobacillus, Leuconostoc, Lactobacillus, Lactiplantibacillus, Pediococcus, Pichia, Rhodotorula, Saccharomycodes, Schizosaccharomyces, and Sphingomonas, which have been reported in microbiota traditional fermented beverages. Dextran, levan, glucan, gellan, cellulose, among others, EPS these genera. Extracellular responsible for contributing to specific...
Lavandula officinalis is a Mediterranean plant to which antimicrobial and antioxidant properties are attributed. The objective of the research was evaluate chemical composition, antibacterial activity dried leaves officinalis. For extraction bioactive compounds, ultrasound used, an environmentally friendly technique, where yield percentage 15.51% obtained. composition evaluated by high-performance liquid chromatography coupled mass (HPLC-MS), it demonstrated that possible extract compounds...
Depressive symptoms are diagnosed by physicians using scales but their pathophysiology is unclear. Low serotonin (5-HT) levels play an important role in depression, and the 5-HT transporter (5-HTT) regulator of plasma reuptake. Additionally, 5-HTT gene-linked polymorphic region (5-HTTLPR) associated with depression. The aim was to clarify roles 5HTTPLR polymorphism depressive older adults. A total 84 adult participants were evaluated. measured Center for Epidemiologic Studies Depression...
Abstract Punica granatum peel is a significant source of polyphenolic compounds that have potential uses as drugs. This study aimed to obtain and purify derived from pomegranate evaluate their anticancer activity in cell lines. Polyphenols the were extracted using hybrid ultrasound‐microwave technology. Different mass:volume ratios water:ethanol used during extraction. Purification was performed on chromatographic column with Amberlite XAD‐16, unfractionated extracts fractions obtained. The...
Mentha piperita L., is one of the most popular and consumed species worldwide because its secondary metabolites with antioxidant properties, among these are polyphenolic molecules. These molecules can be extracted using different methodologies. However, range bioactive compounds in an extract vary factors, including extraction methodology. Recently, use hybrid technologies for plant has been increased since a empowerment various properties obtained extracts demonstrated. In this study was...
