This study explores how varying chlorogenic acid levels (low-yellowish, Y; high-greenish, G) in sunflower proteins (SFs) affect the properties of eugenol-loaded oil-in-water emulsions and the resulting films, while examining the interaction of cellulose nanoparticles (from commercial (CNC) and banana peel sources (CNF)) with the film-forming matrix. This research fills gaps in literature by demonstrating how interactions among proteins, lipids, phenolic compounds, and cellulose nanoparticles influence film properties. The high chlorogenic acid content in SF reduced electrostatic repulsion between protein molecules, causing aggregation, oil droplet flocculation, and increased emulsion viscosity.

Pumpkin seed proteins (PSPs) are a promising resource for obtaining bioactive peptides but their low solubility hinders enzymatic hydrolysis, reducing yield and bioactivity. In addition, enzymatic processes require specific conditions and long processing times; improving the efficiency of this process is essential to expand its industrial applications. In this context, using a high-frequency, low-intensity ultrasound (US) has proven to be an effective strategy for optimizing the hydrolysis of plant protein.

Comparative efficacy of commercial phytases on phosphorus availability for broilers.

Trop Anim Health Prod

March 2025

Department of Animal Sciences, Federal University of Viçosa (UFV), Avenue: P H Rolfs, S/N - Campus Universitário, Viçosa, Minas Gerais, Brazil.

The presence of phytate in broiler diets restricts phosphorus availability, a crucial nutrient for muscle and bone development, leading to reduced performance. To alleviate this issue, exogenous enzymes such as phytase are introduced; however, the wide variety of phytases available on the market and their effectiveness are not yet fully understood. The objective of this study was to evaluate the phosphorus equivalence of commercial phytase in broiler diets, using the standard curve, and its effects on performance, bone mineralization, intestinal histological integrity, liver relative weight, and total alkaline phosphatase in the initial phase (1 to 21 days) of broiler.

During foraging, stingless bees are at risk of pesticide contamination from treated field crops. Frieseomellita varia workers, for example, frequently visit pepper plants that are often treated with the herbicide clomazone (CLZ), the fungicide difenoconazole (DFZ), and the insecticide abamectin (ABM). These pesticides pose a threat not only to adult bees but also to larvae when the chemicals are brought back to the nest.

General combining ability (GCA) is the major selection criterion for new sweetpotato (Ipomoea batatas) parents in a reciprocal recurrent selection (RRS) scheme. Here we aimed to estimate GCA and specific combining ability (SCA) by using 16 potential testers involved in an 8 × 8 partial diallel and propose a procedure to identify testers in sweetpotato breeding. Data on storage root yield in tons per hectare (rytha), and sweetpotato virus disease (vir2) from 64 families (1,913 clones) were collected in five trials at two locations in Uganda.

Exploring the antivirulence potential of phenolic compounds to inhibit quorum sensing in Pseudomonas aeruginosa.

World J Microbiol Biotechnol

January 2025

Food Research Center (FoRC), Laboratory of Food Microbiology, Department of Food and Experimental Nutrition, Faculty of Pharmaceutical Sciences, University of São Paulo (USP), São Paulo, SP, Brazil.

Bacteria coordinate gene expression in a cell density-dependent manner in a communication process called quorum sensing (QS). The expression of virulence factors, biofilm formation and enzyme production are QS-regulated phenotypes that can interfere in human health. Due to this importance, there is great interest in inhibiting QS, comprising an anti-virulence strategy.

In soybean breeding programs, a great deal of time is devoted to the use of methods that perform selection of individual plants during the initial generations. Our hypothesis is that BLUPIS (simulated individual BLUP) can be efficient when applied in the initial stages of soybean breeding programs. This study aimed to explore the potential of BLUPIS in the early generations of a soybean breeding program, as well as to assess the viability of the strategy of dividing the useful area of experimental plots for estimating genotypic effects and plant selection.

Building models that allow phenotypic evaluation of complex agronomic traits in crops of global economic interest, such as grain yield (GY) in soybean and maize, is essential for improving the efficiency of breeding programs. In this sense, understanding the relationships between agronomic variables and those obtained by high-throughput phenotyping (HTP) is crucial to this goal. Our hypothesis is that vegetation indices (VIs) obtained from HTP can be used to indirectly measure agronomic variables in annual crops.
