This study evaluated maltodextrin (MD) and gelatin (GEL) in different ratios (SO1, MD only; SO2, GEL = 2:1; SO3, 1:1, respectively) as wall materials to microencapsulation of sweet orange essential oil (SOEO, 10% w/w). SOEO microspheres were obtained by emulsification/lyophilization characterized regarding the yield efficiency, infrared spectroscopy, ultrastructural aspects (scanning electron microscopy, SEM), thermogravimetric (TG), derivative thermogravimetry (DTG) differential exploratory...
This study aimed to microencapsulate Cymbopogon citratus essential oil (CCEO) with spray drying using maltodextrin and gelatin. The effects of the operational conditions (inlet temperature (130-160 °C), CCEO concentration (5-15%), (10-20%)) on physicochemical stability antioxidant antibacterial activities microcapsules were determined. microencapsulation process had yield encapsulation efficiency values varying from 31.02 77.53% 15.86-61.95%, respectively. against Staphylococcus aureus...
Maize white spot (MWS) caused by Pantoea ananatis in Brazil is among the most impactful foliar diseases affecting maize production, often resulting significant yield losses. To assess how different fungicide types influence disease control and response, we analyzed data from 87 independent field trials conducted over a nine-year period (2016–2024) across five Brazilian states Distrito Federal. Eight treatments were included, each evaluated at least 19 with available severity data. Two...
Maize white spot (MWS) caused by Pantoea ananatis in Brazil is a yield limited disease. However, recent studies have not quantitatively assessed the relationship between disease severity and crop yield. In this study, we evaluated association using Fisher's Z (Z) correlation coefficient (𝑟), as well meta-analytic random-coefficients models, from which estimated intercept (β0) slope (β1) of regressions. We also tested influence potential moderator variables (yield class, region). Finally,...

ABSTRACT This work investigates the removal of Cd 2+ , Cu Ni and Pb ions from aqueous solutions using tururi fibers as an adsorbent under both batchwise fixed‐bed conditions. It was found that modification with sodium hydroxide increased adsorption efficiencies all metal studied. The fractional factorial design showed pH, mass, agitation rate, initial concentration influenced each differently. kinetics multi‐element equilibria were reached after 15 min following pseudo‐second‐order kinetics....
The high ureolytic activity of rumen microbiota is a concern when urea used in ruminant feed, because it leads to fast conversion, resulting possible intoxication and lower nitrogen utilization. This study intended microencapsulate using carnauba wax obtain slow-release systems the rumen. experiment was conducted randomized block design, arranged 3 × 2 factorial, with encapsulated ratios 1 : 2; 3, 4 (UME UME 4) two particles sizes (small, PS ; large, PL ).All formulations showed excellent...
Methionine microencapsulated in a lipid matrix of carnauba wax by the melt-emulsification method was investigated to protect amino acid from ruminal degradation, making methionine available for use directly intestine. Pure compared with two formulations obtained ratios 2:1 and 4:1, wax: (MEM MEM 4:1), respectively. Scanning electron micrographs both after situ testing showed no attack microorganisms. There higher degradability dry matter (DM) crude protein (CP) pure confirming...
A growing global trend for maximum use of natural resources through new processes and products has enhanced studies exploration renewable materials. In this study, cardanol, a component the cashew nut shell liquid (CNSL), was used as building block development thermosetting matrix, which reinforced by raw modified sponge gourd fibers (Luffa cylindrica). DSC TG results showed that among biocomposites, one treated with NaOH 10 wt% (BF10) had highest thermal stability, besides best performance...
Context Urea is widely used in ruminant diets as a source of non-protein nitrogen (NPN), partially substituting for true protein feed, but high levels urea the diet may cause toxicity. Aims This study investigated microencapsulation carnauba wax slow release rumen to improve N efficiency and growth sheep. Methods Two microencapsulated systems were developed with urea:carnauba ratios (w/w) 1:2 (U12) 1:4 (U14). Based on initial characterisation, only U12 was examined an vivo experiment Santa...
Foi avaliada a utilização da mucilagem de quiabo como alternativa para agregação valor em molho tomate, atuando agente espessante na forma in natura e liofilizada. A foi extraída do liofilizada, sendo caracterizada quanto ao rendimento, propriedades funcionais, físico-químicas, bioativas, colorimétricas sensoriais. Foram empregadas formulação molhos tomate três formulações, uma sem (controle) duas com úmida apresentou rendimento extração 53,87% e, quando 1,67%, apresentando maior...
