This study aimed to evaluate the antimicrobial effectiveness of cumin seed essential oil (CEO) after encapsulation in chickpea protein-maltodextrin matrix by spray drying and to provide insight into potential use as a natural ingredient in meat-based products. The surface morphology results of encapsulated CEO showed the dispersion in the wall material matrix, and the observed specific common peaks in the FT-IR spectra of encapsulated and non-encapsulated CEO proved the successful encapsulation. The antibacterial activity of non-encapsulated CEO against BC1402, ATCC 27853, Typhimurium ATCC 0402, ATCC 25923 were first evaluated by disc diffusion assay.

Additive manufacturing (AM) techniques have the potential to produce complex parts, and many of these techniques require the use of support structures to prevent deformations and to minimize thermal effects during the printing process, particularly when building overhangs and internal cavities. However, removing the support structures through postprocessing incurs additional costs and time penalties. Unlike other AM techniques, support structures are not used in directed energy deposition (DED) technique due to its working principle.

The increasing prevalence of metabolic diseases and the global drive toward achieving Sustainable Development Goals (SDGs) underscore the need for sustainable, nutrient-dense foods. Soybeans (Glycine max), a critical global crop, offer promising solutions; however, their predominant use as animal feed raises concerns regarding food security and environmental sustainability. Fermented soy products-including tempeh, natto, and miso-are rich in bioactive compounds such as peptides and isoflavones, which offer potential therapeutic effects and hold cultural and nutritional significance.

Article Synopsis
  • The study investigates the impact of physical activity (PA) on sedentary behavior and body measurements in children and adolescents, highlighting a trend where physical activity decreases and sedentary time increases with age.
  • In a sample of 759 participants aged 6-17, results revealed children are less sedentary and more active than adolescents, with significant differences in body composition measurements based on physical activity levels.
  • The findings suggest that physically active individuals, especially boys, had lower body fat percentages and slimmer skinfold measurements compared to inactive peers, indicating that engaging in recommended levels of PA may mitigate obesity risks.

Pickering emulsions (PEs) can be used as efficient carriers for encapsulation and controlled release of different bioactive compounds. Recent research has revealed the potential of prolamins in development of nanoparticle- and emulsion-based carriers which can improve the stability and bioavailability of bioactive compounds. Prolamin-based particles have been effectively used as stabilizers of various PEs including single PEs, high internal phase PEs, multiple PEs, novel triphasic PEs, and PE gels due to their tunable self-assembly behaviors.

Alignment of each optical element at a synchrotron beamline takes days, even weeks, for each experiment costing valuable beam time. Evolutionary algorithms (EAs), efficient heuristic search methods based on Darwinian evolution, can be utilized for multi-objective optimization problems in different application areas. In this study, the flux and spot size of a synchrotron beam are optimized for two different experimental setups including optical elements such as lenses and mirrors.

Anemia resulting from iron (Fe) deficiency is a global public health problem. The deficiency of Fe is usually due to insufficient dietary intake of iron, interaction of Fe with other food components, and thus low bioaccessibility/bioavailability. Fe encapsulation has the potential to tackle some major challenges in iron fortification of foods.

The polymer electrolyte membrane and its contact with electrodes has a significant effect on the performance of fuel and electrolysis cells but the choice of commercially available membranes is limited. In this study, membranes for direct methanol fuel cells (DMFCs) were made by ultrasonic spray deposition from commercial Nafion solution; the effect of the drying temperature and presence of high boiling solvents on the membrane properties was then analyzed. When choosing suitable conditions, membranes with similar conductivity, water uptake, and higher crystallinity than comparable commercial membranes can be obtained.

Chitosan (CS), a bio-renewable natural material, has the potential to be utilized as a biopolymer for food packaging films (PFs)/coatings. However, its low solubility in dilute acid solutions and poor antioxidant and antimicrobial activities limit its application in PFs/coatings. To address these restrictions, chemical modification of CS has garnered increasing interest, with graft copolymerization being the most extensively used method.

With the constant increase in protein demand globally, it is expedient to develop a strategy to effectively utilize protein, particularly those extracted from plant origin, which has been associated with low digestibility, poor techno-functional properties, and inherent allergenicity. Several thermal modification approaches have been developed to overcome these limitations and showed excellent results. Nevertheless, the excessive unfolding of the protein, aggregation of unfolded proteins, and irregular protein crosslinking have limited its application.
