The International Dysphagia Diet Standardization Initiative (IDDSI) framework classified all the samples as level 4 (pureed) foods, demonstrating shear-thinning behavior, a positive attribute for dysphagia patients, according to the results. Testing the rheology of a food bolus at 50 s-1 shear rate, revealed that salt and sugar (SS) elevated viscosity, while vitamins and minerals (VM) led to a viscosity decrease. Elastic gel system reinforcement was achieved through the combined efforts of SS and VM, while SS also improved the storage and loss moduli. VM improved the hardness, gumminess, chewiness, and richness of the color, nonetheless, a small amount of residue lingered on the spoon. Through its impact on molecular linkages, SS promoted better water retention, chewiness, and resilience, thus improving swallowing safety. The food bolus experienced an improvement in taste due to SS's contribution. In dysphagia, foods containing VM and 0.5% SS garnered the top scores in sensory evaluations. This study may underpin the theoretical considerations for the creation and formulation of novel nutritional food products designed to address dysphagia.
We aimed to extract rapeseed protein from by-products in this study and investigate the resulting laboratory-produced protein's impact on emulsion properties, specifically concerning droplet size, microstructure, color, encapsulation, and apparent viscosity. High-shear homogenization techniques were employed to create rapeseed protein-stabilized emulsions, incrementally incorporating milk fat or rapeseed oil (10%, 20%, 30%, 40%, and 50% v/v). Regardless of the lipid type or the concentration tested, every emulsion achieved 100% oil encapsulation during the 30-day storage period. Rapeseed oil emulsions were resilient to coalescence, whereas milk fat emulsions demonstrated a degree of partial micro-coalescence, exhibiting a nuanced difference in their responses. With an increase in lipid concentration, the apparent viscosity of emulsions is elevated. All the emulsions displayed a characteristic shear-thinning behavior, typical of non-Newtonian fluids. Milk fat and rapeseed oil emulsions exhibited an increase in average droplet size correlating with lipid concentration. A simple way to generate stable emulsions offers a viable tactic for converting protein-rich byproducts into a valuable delivery system for either saturated or unsaturated lipids, which will support the design of foods with a specific lipid profile.
The food we consume daily is vital to our health and well-being, and the knowledge and practices surrounding its importance have been carefully preserved and passed down from countless generations of ancestors. Systems provide a framework for comprehending the vast and diverse body of agricultural and gastronomic knowledge, painstakingly collected over evolutionary time. Concurrent with the evolution of the food system, the gut microbiota also underwent adjustments, resulting in a variety of impacts on human health. The gut microbiome's impact on human health, including its positive contributions and negative ramifications, has been a growing area of study in recent decades. Various studies have corroborated the notion that an individual's gut microorganisms are influential in determining the nutritional value of consumed foods, and that dietary choices, reciprocally, influence both the gut microbiota and the microbiome. The current review explores the historical transformations of the food system and their influence on the gut microbiome's structure and evolution, contextualizing this relationship within the broader clinical context of obesity, cardiovascular disease, and cancer. After a short exploration of the diverse food supply and the intricate workings of the gut microbiome, our focus turns to the association between the evolution of food systems and adjustments in gut microbiota composition, closely tied to the increasing incidence of non-communicable diseases (NCDs). Furthermore, we describe strategies for sustainable food systems to restore healthy gut microbiota, preserve the host's intestinal barrier and immune defenses, and reverse the advancement of non-communicable diseases (NCDs).
Using voltage and preparation time variations, the concentration of active compounds within the novel non-thermal processing method, plasma-activated water (PAW), is routinely modulated. Our recent modification of discharge frequency resulted in improved PAW characteristics. The current study selected fresh-cut potato as its model, and pulsed acoustic waves (PAW) at a frequency of 200 Hz (200 Hz-PAW) were prepared. A comparison of its effectiveness was made against PAW, which was prepared using a frequency of 10 kHz. The 200 Hz-PAW system exhibited substantially increased ozone, hydrogen peroxide, nitrate, and nitrite levels, measured at 500-, 362-, 805-, and 148-fold the amounts found in the 10 kHz-PAW system. PAW treatment's effect was to inactivate the browning enzymes, polyphenol oxidase, and peroxidase, thereby reducing the browning index and preventing browning; The 200 Hz-PAW treatment demonstrated the lowest values for these parameters during storage. Cell wall biosynthesis PAW treatment, in conjunction with PAL activation, fostered phenolic compound formation and heightened antioxidant capacity, thereby mitigating malondialdehyde accumulation; the 200 Hz frequency of PAW stimulation proved most effective. Particularly, the 200 Hz-PAW group had the lowest rates of both weight loss and electrolyte leakage. IWR-1-endo cell line The 200 Hz-PAW treatment group demonstrated, in the microbial analysis, the lowest prevalence of aerobic mesophilic bacteria, mold, and yeast during the period of storage. The results indicate a potential application of frequency-controlled PAW technology for fresh-cut produce preservation.
The study assessed how the replacement of wheat flour with three distinct levels (10% to 50%) of pretreated green pea flour influenced the quality of fresh bread during storage for seven days. Rheological, nutritional, and technological characteristics were assessed for dough and bread enriched with conventionally milled (C), pre-cooked (P), and soaked under-pressure-steamed (N) green pea flour. Legumes, in contrast to wheat flour, exhibited lower viscosity, but higher water absorption, development time, and a diminished retrogradation tendency. Bread incorporating C10 and P10 at 10% levels showed similar specific volume, cohesiveness, and firmness to the control; higher concentrations of these additives reduced the specific volume and increased the firmness of the bread. Legume flour (10%) addition during storage slowed down staling. Composite bread contributed to increased protein and fiber intake. The starch digestibility rate was lowest for C30; conversely, pre-heated flour exhibited improved starch digestibility. Finally, P and N are instrumental in producing bread that is both soft and dependable in its structure.
For the production of high-moisture meat analogues (HMMAs), understanding the texturization process of high-moisture extrusion (HME) hinges on a precise determination of the thermophysical properties of high-moisture extruded samples (HMESs). In this study, the goal was to determine the thermophysical properties of high-moisture extruded samples made using soy protein concentrate, brand ALPHA 8 IP. Experimental determination and subsequent investigation of thermophysical properties, including specific heat capacity and apparent density, led to the development of straightforward predictive models. Comparative analysis was performed between these models and literature models derived from high-moisture foods, including those from soy, meat, and fish sources (without high-moisture extracts, HME). long-term immunogenicity Besides that, thermal conductivity and thermal diffusivity were assessed using generalized equations and models referenced in literature, displaying a substantial mutual influence. A satisfying mathematical description of the HME samples' thermophysical properties arose from the integration of experimental data with the application of simple prediction models. Understanding the texturization effect observed during high-moisture extrusion (HME) may benefit from the application of data-driven thermophysical property models. Furthermore, the acquired knowledge can be instrumental in deepening comprehension within pertinent research areas, such as numerical simulations of the HME procedure.
The impact of dietary habits on health outcomes has led to considerable changes in people's eating patterns, including replacing high-calorie snack options with healthier choices, for example, foods infused with beneficial probiotic organisms. The research sought to compare two approaches to creating probiotic freeze-dried banana slices. The first technique used a Bacillus coagulans suspension for impregnation, and the second method involved a starch dispersion containing the bacteria to create a coating. Viable cell counts exceeding 7 log UFC/g-1 were observed in both procedures, though the starch coating mitigated significant viability loss during lyophilization. The shear force test results showed that the crispness of the impregnated slices exceeded that of the coated slices. Yet, the panel of sensory testers, exceeding one hundred in number, did not discern substantial variations in the texture. Both probiotic and coated slices exhibited promising results in terms of viability and consumer preference, with the coated slices notably favored over the non-probiotic controls.
Different botanical sources of starch contribute to varied pasting and rheological properties of starch gels, thereby facilitating the assessment of their applications in the pharmaceutical and food sectors. Nevertheless, the manner in which these characteristics are altered by starch concentration, and their reliance on amylose content, thermal properties, and hydration characteristics, remain inadequately understood thus far. A rigorous examination of starch gels' pasting and rheological properties was executed, encompassing samples from maize, rice (normal and waxy), wheat, potato, and tapioca, at concentrations of 64, 78, 92, 106, and 119 g per 100 g. The results' evaluation prioritized determining the potential equation's fit between parameters and each different concentration of gel.
