This study confirmed the possibility of biopolymer-type stabilizers to increase the saturation concentration of branched-chain amino acids by preventing their crystallization/precipitation. Although microfluidization increased the initial solubility, it failed to increase the saturation concentration of the branched-chain amino acids. The saturation concentration of the branched-chain amino acids increased from 3.81% to 4.42% and 4.85% after the incorporation of food hydrocolloids and proteins, respectively...

The effects of hydrocolloids (hydroxypropylmethylcellulose (HPMC), Carboxymethylcellulose (CMC), xanthan gum (XG), and apple pectin (AP)) at different concentrations on dough thermo-mechanical properties and in vitro starch digestibility of gluten-free potato steamed bread were investigated. Results showed that hydrocolloids addition significantly increased the gelatinization temperature (from 52.0 to 64.2°C) and water absorption (from 56.22 to 66.50%) of potato dough. Moreover, hydrocolloids may be interacted with protein and starch, the density of potato protein bands was decreased by hydrocolloids addition, the reason might be that higher molecular weight complexes might be formed between proteins-hydrocolloids or proteins-proteins, thus change the protein solubility...

The incorporation of probiotics and bioactive compounds, via plasticised thin-layered hydrocolloids, within food products has recently shown potential to functionalise and improve the health credentials of processed food. In this study, choice of polymer and the inclusion of whey protein isolate was evaluated for their ability to stabalise live probiotic organisms. Edible films based on low (LSA) and high (HSA) viscosity sodium alginate, low esterified amidated pectin (PEC), kappa-carrageenan/locust bean gum (κ-CAR/LBG) and gelatine (GEL) in the presence or absence of whey protein concentrate (WPC) were shown to be feasible carriers for the delivery of L...

Iatrogenic lip injury is a rather common complication after facial bone surgery, but is usually treated lightly by the surgeon compared with other more severe functional complications. However, these injuries can have permanent sequelae and can therefore be a reason for patient dissatisfaction, especially after cosmetic surgery. Intraoperative lip injuries during facial bone surgery are usually caused by heat-generating surgical instruments or forced traction on the operative fields. The authors have applied a special technical strategy using a hydrocolloid dressing material to avoid these intraoperative lip injuries...

BACKGROUND: The consistency of sweetened yoghurt (misti dahi) is a desired characteristic which is attributed to the casein protein network formation during fermentation. Unfortunately, this property is lost in the reconstituted sweetened yoghurt (RSY) due to the irreversible nature of protein denaturation during spray drying. Therefore, this study aimed to increase the consistency of RSY using different hydrocolloids. RESULTS: The effects addition of guar gum, pectin, κ-carrageenan and gelatin (0...

High-protein intermediate moisture food (HPIMF) containing sodium caseinate (NaCN) often gave a harder texture compared with that made from whey proteins or soy proteins, due to the aggregation of protein particles. The objectives of this study were to explore whether the addition of hydrocolloids could soften the texture and illustrate the possible mechanism. Three kinds of hydrocolloids, xanthan gum, κ-carrageenan, and gum arabic were chosen, and samples including of these three kinds of hydrocolloids were studied through texture analysis using a TPA test and microstructure observation by confocal laser scanning microscopy (CLSM) and scanning electron microscopy (SEM)...

Model systems formed by sodium caseinate (NaCAS) and espina corona gum (ECG) were studied. There was no evidence of attractive interactions between NaCAS and ECG macromolecules. Aqueous mixtures of NaCAS and ECG phase-separate segregatively over a wide range of concentrations. According to the images obtained by confocal laser scanning microscopy, NaCAS particles form larger protein aggregates when ECG is present in the system. An increase in the hydrodynamic diameter of NaCAS particles, as a result of ECG addition, was also observed by light scattering in diluted systems...

Diabetic foot ulcers (DFUs) are the chronic, non-healing complications of diabetic mellitus which compels a significant burden to the patients and the healthcare system. Peripheral vascular disease, diabetic neuropathy, and abnormal cellular and cytokine/chemokine activity are among the prime players which exacerbate the severity and prevent wound reapir. Unlike acute wounds, DFUs impose a substantial challenge to the conventional wound dressings and demand the development of novel and advanced wound healing modalities...

Recent market developments raised the need for alternatives to hydrocolloids as texture improver in gluten-free bread. Chickpea exerts several physicochemical properties (water- and oil-binding, emulsifying and foaming) that might address this need. Therefore, the effect of processing on chickpea functionality was tested on low ingredient dose, comparably to that of common hydrocolloids. Control bread was small, hard and with low gas retention ability as shown by microscopy, depicting holes inside crumb pores...

BACKGROUND: Pressure ulcers, also known as bedsores, decubitus ulcers and pressure injuries, are localised areas of injury to the skin or the underlying tissue, or both. Dressings are widely used to treat pressure ulcers and promote healing, and there are many options to choose from including alginate, hydrocolloid and protease-modulating dressings. Topical agents have also been used as alternatives to dressings in order to promote healing.A clear and current overview of all the evidence is required to facilitate decision-making regarding the use of dressings or topical agents for the treatment of pressure ulcers...

The influence of hydrocolloids on in vitro starch digestibility and rheological properties of Segoami (a new rice variety fortified with amylose and dietary fiber) gel was investigated in terms of type (sodium alginate, arabic gum, guar gum, locust bean gum, and xanthan gum) and addition levels (0.3-0.7% for rice flour weight) of hydrocolloids. In addition, the behavior of hydrocolloids was analyzed by principal component analysis (PCA) based on both properties of various Segoami-hydrocolloids gels. The first and second principle components (PC) explained 80...

Split-thickness skin grafting (STSG) is the most common reconstructive procedure in managing burn injuries. Harvesting split-thickness skin creates a new partial thickness wound referred to as the donor site. Pain at the donor site is reported to be one of the most distressing symptoms during the early post-operative period. Here, we a) identify strategies for managing donor site pain, b) assess the quality of individual studies and c) formulate evidence-based recommendations based on the amount and consistency of evidence...
