Beetroot extract at a concentration of 0.02% demonstrates heightened whiteness, reduced redness, and amplified yellowness in both raw and cooked MMMS samples. Research into meat-mimicking meals (MMMs) formulated with pea protein, flaxseed, rapeseed oil, and beetroot extract shows promise as a sustainable and viable food alternative, potentially leading to wider consumer acceptance as a meat substitute.
The impact of 24 hours of solid-state fermentation (SSF) or submerged fermentation (SMF) with the Lactiplantibacillus plantarum strain No. 122 on the physical and chemical attributes of chia seeds (CS) was the focus of this study. Additionally, this research examined the effects of adding fermented chia seeds at varying concentrations (10%, 20%, and 30%) on the properties and sensory profile of wheat bread. The fermented chia seeds underwent analysis of acidity, viable lactic acid bacteria (LAB) counts, biogenic amine (BA) levels, and fatty acid (FA) profiles. Detailed analysis of the resultant breads involved quantifying acrylamide, assessing fatty acid and volatile compound composition, evaluating sensory characteristics, and determining overall consumer acceptability. In fermented cow's milk (FCM), there was a decrease in specific branched-chain amino acids (BCAAs) and saturated fatty acids (SFAs), and an increase in polyunsaturated fatty acids (PUFAs), including omega-3 (-3). Identical FA profiles were noted in both breads, those containing non-fermented cereal starch (NFCS) and those containing fermented cereal starch (FCS). The wheat bread's quality parameters, VC profile, and sensory traits were considerably affected by the inclusion of NFCS or FCS in its formula. The presence of supplements in the bread resulted in reduced specific volume and porosity, but the inclusion of SSF chia seeds significantly enhanced moisture levels and decreased the extent of mass loss after the baking process. The lowest acrylamide concentration was ascertained in bread with a 30% addition of SSF chia seeds (115 g/kg). Compared to the control bread, the overall acceptance of supplemented loaves was lower. However, breads fortified with 10% and 20% SMF chia seed concentrations were still quite favorably received, earning an average score of 74. Fermentation using Lactobacillus plantarum demonstrably enhances the nutritional profile of chia seeds, whereas the addition of NFCS and FCS, within specific concentrations, leads to an improved fatty acid composition, enhanced sensory qualities, and a decrease in acrylamide levels in wheat bread.

Substantial interactions between mung bean proteins and polyphenols are common during storage and processing procedures. Utilizing globulin derived from mung beans as the initial component, this study further integrated ferulic acid (a phenolic acid) and vitexin (a flavonoid). Employing a multi-faceted approach incorporating physical and chemical indicators, spectroscopy, and kinetic methods, statistical analysis (SPSS and peak fit data) was applied to quantify the conformational and antioxidant activity changes of mung bean globulin and two polyphenol complexes, both before and after heat treatment, revealing the differences and interaction mechanisms of globulin with the two polyphenols. An increase in polyphenol concentration demonstrably enhanced the antioxidant activity of both compounds. The antioxidant activity of the mung bean globulin-FA complex was, in addition, significantly stronger. Following the application of heat, a considerable downturn was seen in the antioxidant activity of the two substances. The mung bean globulin-FA/vitexin complex's interaction mechanism was characterized by static quenching, a process accelerated by heat treatment. Mung bean globulin and two polyphenols interacted via hydrophobic forces. Following thermal processing, the binding arrangement of vitexin altered to an electrostatic interaction. Absorption peaks in the infrared spectra of the two compounds shifted to different extents, accompanied by new peaks at 827 cm⁻¹, 1332 cm⁻¹, and 812 cm⁻¹. Due to the interaction between mung bean globulin and FA/vitexin, the particle size contracted, the absolute value of the zeta potential augmented, and the surface hydrophobicity lessened. Following heat treatment, both composite samples exhibited a substantial reduction in particle size and zeta potential, accompanied by a marked enhancement in surface hydrophobicity and stability. Mung bean globulin-FA demonstrated enhanced thermal stability and antioxidation capabilities when contrasted with the mung bean globulin-vitexin complex. This research sought a theoretical explanation for the interplay between proteins and polyphenols, along with a theoretical framework for the design and production of functional foods derived from mung beans.

The compressive strength of concrete, a crucial mechanical property, is paramount in this extensively utilized material. To effectively predict CCS, this study implements a novel, integrated method. Electromagnetic field optimization (EFO) is used to favorably tune the artificial neural network (ANN) method suggested. The EFO, employing a physics-based approach, aims to pinpoint the optimal contribution of key parameters including cement (C), blast furnace slag (SBF), fly ash (FA1), water (W), superplasticizer (SP), coarse aggregate (AC), fine aggregate (FA2), and testing age (AT), in this study towards the concrete compressive strength (CCS). The identical task performed by the water cycle algorithm (WCA), the sine cosine algorithm (SCA), and the cuttlefish optimization algorithm (CFOA) is used for a comparative study with the EFO. The results confirm that the ANN's hybridization with the mentioned algorithms provides reliable predictive approaches for the CCS. A comparative assessment suggests substantial distinctions in the prediction capacity of ANNs produced using EFO and WCA, in contrast to those using SCA and CFOA methodologies. In the testing phase, the mean absolute errors for ANN-WCA, ANN-SCA, ANN-CFOA, and ANN-EFO were 58363, 78248, 76538, and 56236, respectively. Beyond that, the EFO showed substantially faster operation than the alternative strategies. For early prediction of CCS, the ANN-EFO stands out as a highly efficient and effective hybrid model. For the convenient estimation of CCS, a user-friendly, explainable, and explicit predictive formula is likewise derived.
