Article Abstract

The present study evaluated the potential of near-infrared (NIR) spectroscopy, conventional digital images, and images with thermal and X-ray filters, coupled with partial least squares (PLS) for the determination of texture profile analysis (TPA), mainly hardness, adhesiveness, springiness, chewiness, gumminess, cohesiveness, and resilience. Furthermore, the approach can be classified as a multivariate multiproduct calibration model since different types of flour were incorporated into each single multivariate model. The models were validated through the parameters of merit estimation, considering accuracy, adjust, linearity, inverse of analytical sensitivity, and limits of detection and quantification. The variable importance in projection (VIP-scores) showed that hardness, gumminess, and cohesion share similar important variables in their modeling, while adhesiveness and elasticity also do. On the other hand, chewability and resilience share common variables in their respective models.

Background: This study aimed to develop gluten-free bread from chickpea flour by incorporation of varying levels (0 (B-C), 2.5 (B-1), 5 (B-2), and 10 g kg (B-3)) of madımak leaf powder (MLP), and to investigate its effect on physicochemical and bioactive properties, glycemic index, texture, and sensory attributes.

Results: Moisture ranged from 229 (B-3) to 244 g kg (control), while ash content increased with MLP, reaching 47 g kg in B-3 compared to 15.

Frozen storage deteriorates the texture and digestibility of frozen rice dough by damaging gliadin structure and starch integrity. This study investigated carboxymethyl chitosan (CMCh) and sodium carboxymethyl cellulose (CMCNa) as cry-oprotectants to mitigate these effects. Comprehensive analysis utilizing nuclear magnetic resonance (NMR), texture profile analysis (TPA), dynamic contact angle measurement (DCAT21), reversed-phase high-performance liquid chromatography (RP-HPLC), and circular dichroism (CD) demonstrated that 1.

College of Osteopathic Medicine, Rocky Vista University, 8401 S Chambers Road, Parker, CO, 80112, United States, 1 9253236431.

Dermal fillers have gained increasing popularity for their ability to enhance facial symmetry, restore volume, and improve skin texture. However, their use in patients with cancer undergoing active chemotherapy and radiation therapy poses unique challenges, as these treatments can alter both the safety profile and efficacy of filler procedures. Chemotherapy can interfere with normal wound healing and immune responses, warranting a more cautious and individualized approach when considering dermal fillers in this population.

Unlabelled: Soy whey, a tofu production byproduct rich in nutrients, is typically discarded. This study investigated five natural lactic acid bacteria (LAB) strains isolated from spontaneously fermented soy whey (FSW) for their fermentation performance in soy whey medium. The growth characteristics, total phenols and flavonoids compounds, antioxidant activities, and aroma profiles were evaluated.
