An attempt was made to analyze the elastic modulus (G0) of chickpea flour (CF)-based muffin batters made with CF alone and with added biopolymers (whey protein (WP), xanthan gum (XG), inulin (INL), and their blends) in order to evaluate their suitability to be a wheat flour (WF) substitute in muffins, and to model the heat-induced gelatinization of batters under non-isothermal heating condition from 25 ◦C to 90 ◦C. A rheological approach is proposed to determine the kinetic parameters (reaction order (n), frequency factor (k0), and activation energy (Ea)) using linearly-increasing temperature...

Progressive loss of muscle mass and strength is a physiological consequence of aging, and without interventions, it usually deteriorates into sarcopenia. In this study, the hypothesis that combined special nutritional-physiotherapeutical intervention to prevent or reverse this biological deterioration in elderly people was tested. The effects of the regular resistance muscle training (PT, n = 17) alone and the combined exercise + special nutrition therapy containing whey protein and vitamin D (PT + NT, n = 17) were monitored for 3 months in 34 elderly patients (12 men and 22 women; mean age: 66...

REVIEW
Jayashree Ramasethu
Nosocomial or hospital acquired infections threaten the survival and neurodevelopmental outcomes of infants admitted to the neonatal intensive care unit, and increase cost of care. Premature infants are particularly vulnerable since they often undergo invasive procedures and are dependent on central catheters to deliver nutrition and on ventilators for respiratory support. Prevention of nosocomial infection is a critical patient safety imperative, and invariably requires a multidisciplinary approach. There are no short cuts...

Proteins are known to be effective building blocks when it comes to structure formation in aqueous environments. Recently, we have shown that submicron colloidal protein particles can also be used to provide structure to liquid oil and form so-called oleogels.1 Preventing extensive agglomeration of these submicron building blocks is a prerequisite to allow for efficient structure formation. This was achieved by applying a solvent exchange procedure to transfer the building blocks from water to oil. The aim of the current paper was to elucidate on the enhanced stability against agglomeration of heat-set whey protein isolate (WPI) aggregates in oil after applying such a solvent exchange procedure...

The requirement for validation of allergen cleaning processes is increasing. The use of lateral flow devices (LFDs) to identify allergens has rapidly expanded, but the best practices for use of these devices are still developing. The goal of this study was to compare commercially available milk-specific LFDs and a general protein identification method. Five milk proteins and seven milk-derived ingredients were tested at several concentrations with eight milk-specific LFDs and a general protein identification kit...

BACKGROUND: Immediate type hypersensitivity to vaccines containing bovine/porcine excipients, such as the measles, mumps and rubella (MMR) vaccine is probably due to sensitization to bovine/porcine gelatin. Most patients with such reactions in Sri Lanka have cow's milk (CM) or beef allergy. OBJECTIVES: We investigated whether those who had beef and CM allergy had a higher incidence of hypersensitivity reactions to vaccines and the possible trigger of such reactions...

BACKGROUND: Previous research has demonstrated the permissive effect of insulin on muscle protein kinetics, and the enhanced insulin sensitizing effect of chromium. In the presence of adequate whole protein and/or essential amino acids (EAA), insulin has a stimulatory effect on muscle protein synthesis, whereas in conditions of lower blood EAA concentrations, insulin has an inhibitory effect on protein breakdown. In this study, we determined the effect of an amylopectin/chromium (ACr) complex on changes in plasma concentrations of EAA, insulin, glucose, and the fractional rate of muscle protein synthesis (FSR)...

Classical and probiotic set yogurt were made using non-standard heat treatment of sheep's milk at 60°C/5min. Physico-chemical properties, sensory characteristics, and the viability of bacteria that originated from cultures in classical and probiotic yogurt were analysed during 21days of storage at 4°C. For the production of yogurt, a standard yogurt culture and a probiotic strain Lactobacillus rhamnosus GG were used. At the end of storage time of the classical and probiotic yogurt the totals of non-denatured whey proteins were 92...

Enzymatic hydrolysis of proteins from rice, soy, pea and wheat, with both chymotrypsin and thermolysin, resulted in hydrolysates, which are efficient inhibitors of the angiotensin-converting enzyme (ACE). IC50 values of the hydrolysates were between 27 and 39mg/l, which is comparable to enzymatically hydrolysed whey protein. A significant increase of the ACE-inhibiting effect was observed following butanol extraction due to accumulation of hydrophobic peptides (IC50 between 12 and 21mg/l). Based on the identification and quantification of individual tryptophan-, tyrosine- and phenylalanine-containing dipeptides, 50-80% of the total ACE-inhibiting potential of butanol extracts from plant protein hydrolysates could be explained...

BACKGROUND: Diabetes mellitus (DM) is associated with severe immune system complications. Camel whey protein (CWP) decreases free radicals (ROS) and modulates immune functions, but its effect on DM-impaired immune systems has not been studied. We investigated the impact of CWP on the immune system in a Type 1 diabetes mouse model. METHODS: Three experimental groups were used: (1) non-diabetic control; (2) diabetic; and (3) CWP-treated diabetic mice. RESULTS: Induction of diabetes by streptozotocin was associated with reduction of body weight and insulin level, increase in glucose level and pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α), and reduction in IL-2 and IL-4 levels...

The effects of tapioca starch (TS) and potato starch (PS) on texture properties of whey protein isolate (WPI)/starch co-gels were investigated for fracture structures. We focused on two types of WPI network structures. In a fine-stranded structure at pH 6.8, the WPI/TS co-gel fractured similarly to the WPI single gel. The WPI/PS co-gel was broken at a lower strain and lower stress. In a random aggregation at pH 5.8, the WPI/TS co-gel reached a yielding point at a lower strain, whereas the WPI/PS co-gel fractured at a higher strain and higher stress...

Many drugs and phytochemicals are bitter, leading to noncompliance with prescriptions and avoidance of healthy foods and a need to suppress their taste. The goal of this study was to investigate the binding of bitterants (quinine and caffeine) by whey protein isolate (WPI) and the effect on perceived bitterness. Caffeine interacted minimally with WPI, while the proportion of unbound quinine decreased exponentially with protein concentration. Molecular modeling was used to show the energy of the quinine-Β-lactoglubulin interaction was an order of magnitude greater than the caffeine-Β-lactoglobulin interaction...

The objective of this study was to determine the possible source of predominant Bacillus licheniformis contamination in a whey protein concentrate (WPC) 80 manufacturing plant. Traditionally, microbial contaminants of WPC were believed to grow on the membrane surfaces of the ultrafiltration plant as this represents the largest surface area in the plant. Changes from hot to cold ultrafiltration have reduced the growth potential for bacteria on the membrane surfaces. Our recent studies of WPCs have shown the predominant microflora B...

BACKGROUND: Inadequate nutritional intake and altered response of aging muscles to anabolic stimuli from nutrients contribute to the development of sarcopenia. Nutritional interventions show inconsistent results in sarcopenic older adults, which might be influenced by their basal nutritional status. OBJECTIVE: To test if baseline serum 25-hydroxyvitamin D (25(OH)D) concentrations and dietary protein intake influenced changes in muscle mass and function in older adults who received nutritional intervention...

Type I diabetes (T1D) is a characterized by the inflammation of pancreatic islets and destruction of β cells. Long and persistent uncontrolled diabetes tends to degenerate the immune system and increase the incidence of infections in diabetic individuals. Most serious diabetic complications are mediated by the free radicals, which damage multiple cellular components through direct effects of the cell cycle regulatory proteins. Camel whey protein (CWP) has antioxidant activity and decreases the effects of free radicals...

This study sought to determine the effects of soy-whey blended protein supplementation on sports performance and related biochemical parameters after long-term training. After a week of adaptation, eighteen 6-week-old male Wistar rats were randomly assigned to 3 groups: the standard chow diet plus whey protein (Whey) group, the standard chow diet plus soy-whey blended protein (BP) group and the standard chow diet only (control) group. Each group included 6 rats for the seven-week experiment. Before the experiment, the baseline values of body weight, grasping force and time to exhaustion due to the loaded-swimming test were recorded for each group...
