A new probiotic product named ROSALACT was obtained from pasteurized milk with medicinal plants extracts (rosehip extract and liquorice extract) using a mixed culture of probiotic bacteria ABT 5, supplied by Chr. Hansen (Copenhagen, Denmark). The probiotic dairy product ROSALACT followed to combine the beneficial effects of probiotic bacteria with the therapeutic virtues of medicinal herbs. The aim of the present study was to characterize from sensorial and rheological stand point the probiotic product ROSALACT. The novel product was appreciated by the panelists (especially taste, appearance, texture and aftertaste), and rheological measurements show the ROSALACT product is a non-Newtonian fluid, with characteristics independent of time.
Rheological properties of different types of mayonnaise
2019
A MCR301 rheometer from Anton Paar, fitted with a PP50 plate/plate system was used to investigate the rheological properties of some fulland low-fat mayonnaises. The test conditions were relevant for the use of mayonnaise in the preparation of typical food dishes. A hysteresis test was run to investigate the thixotropic nature of the mayonnaise at +4○C. A strain controlled amplitude sweep was run at 4, 14 and 24○C. The samples were then cooled to -15○C at a rate of 0.5○C/min in rotation at 50 1/s to detect the freezing temperature of the different products. A Malvern Mastersizer 3000 was used to measure particle sizes in a selection of the mayonnaises investigated. pH in the mayonnaise was measured directly at 20oC. Commercially produced low fat mayonnaise did not behave very different from commercially full fat mayonnaise. The results did not show significant differences between the investigated mayonnaises on all the measured parameters, except for the particle size of the emulsio...
Rheological characteristics salad mayonnaise with hens and quail egg yolks
2015
In this paper, the influence of certain ingredients (oil phase, types of carbohydrates, milk components, peas powder, highly concentrated soy protein powder, hens and quail egg yolks) on the rheological characteristics of the salad mayonnaise were investigated. The oil phase of mayonnaise (60%) seems refined sunflower oil (linoleic type, high oleic type). Of carbohydrates used are glucose, lactose, sucrose and inulin HD. For dairy component of mayonnaise whole milk, skim milk, whey powder, soy drink, highly concentrated soy protein and peas powder were used. Samples of mayonnaise were prepared with hens and quail egg yolks (fresh, pasteurized, granules). Mechanical homogenization process of mayonnaise was conducted in 10 000 rpm and the preparation time was 1.5 minutes, at room temperature. Measuring rheological properties was conducted on a rotational viscometer with concentric spindles at 10 ˚C and 25 ˚C. Effect of hens and quail egg yolks on change of color salad mayonnaise was s...

Reduced-fat products can help to fight obesity and its associated health risks. To develop appealing products, both product-specific fat replacers and suitable analytical methods for the characterization of fat-associated properties are important. The rheology, tribology, texture, and spreadability of a reduced-fat mayonnaise with different concentrations of corn dextrin were analyzed to determine properties such as flow behavior, viscosity, lubricity, firmness, and stickiness. Additionally, a sensory panel analyzed the samples for their mouthfeel (creaminess, firmness, and stickiness). Correlations between the results of the instrumental methods suggested that the analytical effort for the future development of appealing reduced-fat food products can be reduced. In addition, several correlations were identified between the instrumental and the sensory data. Results from tribological measurements correlated with the sensory attribute of stickiness, suggesting that tribometry can com...

Egg yolk was replaced with sesame–peanut meal milk in mayonnaise in the levels of 0, 25%, 50%, 75%, and 100%. The pH was significantly decreased by increasing the percentage of replacement in all three kinds of replacement (p < .05). However, over the whole period, no significant difference was observed in the acidity. The mayonnaise samples, except for the replacements of 50%, were desirable in terms of physical and thermal stability. A significant decrease was seen in lightness (L*) and yellowness (b*) of the samples as a result of an increase in the percentage of replacements (p < .05). In the power law model, the flowing index amount (n) of all samples was in the domain between zero and one, which served as evidence for pseudoplastic behavior (dilatant with shear) of mayonnaise samples. The positive results are employing suitably the sesame–peanut meal milk instead of egg yolk, decreasing the cholesterol of mayonnaise and increasing its nutritional value, proposing mayonna...

Peanut, sesame, and (peanut:sesame (1:1)) meal milk were used as the egg yolk substitute at the levels of 0%, 25%, 50%, 75%, and 100% in mayonnaise. Then, the rheological, textural (hardness, adhesive force, and adhesiveness), and microstructural properties of samples were evaluated on the first day after production. The oscillatory test indicated that all treatments had shear thinning flow behavior and in low-angular frequencies had higher elastic modulus than the viscous modulus (tan δ < 1), but in the P-S50 and P-S100, P75 and S75 in angular frequencies higher than 63 rad.s−1, tan δ was more than one (i.e. G″ > G′) which indicated more viscous modulus (liquid-like flow behavior) than the elastic modulus (gel-like flow behavior). The optical microscopy confirmed that the oil particle size in blank, 25 and 50% of substitution was of smaller size, and the fat droplets had a monotonous and regular form. In 75 and 100% of substitution, the oil particle size was larger and more i...

Mayonnaise is a mixture of egg yolk, vinegar, water, spices and 70-80% oil forming a semi-solid oil-in-water emulsion. When preparing a low-fat mayonnaise with an increased water content, thickening agents are required for increased viscosity and emulsion stability. The hydrocolloids xanthan gum and guar gum are sometimes used for this purpose and they act synergistically creating a viscosity increase. However, guar gum has poor acid stability, and because mayonnaise is an acidic product guar gum will eventually start to degrade causing a viscosity decrease and subsequent emulsion separation. Despite this fact, guar gum and xanthan gum are extensively used in mayonnaises today. The aim of this degree project was to explore how the synergy between guar gum and xanthan gum influences the viscosity of a low fat mayonnaise and whether high acidity will have an impact on the viscosity over a 4-week period. This was to examine if and if so, how a mayonnaise recipe can be modified to maintain a cost efficient product with the desired rheological properties in times of hydrocolloid price fluctuations. The study was conducted by preparing 15 mayonnaises with 50% fat, either at pH 3,5; 4 or 5 and a total of 0,6 % hydrocolloids with varying proportions of guar gum and xanthan gum. The mayonnaise samples were studied by measurements of viscosity, color changes and a visual comparison of their mayonnaise-like flow-properties compared to Hellmann's Real Mayonnaise used as reference.
Tucupi-added mayonnaise: Characterization, sensorial evaluation, and rheological behavior
CyTA - Journal of Food
The aim of this work was to elaborate a tucupi-added mayonnaise and to assess the physicochemical characteristics, as well the rheological behavior at temperatures from 20°C to 70°C of the product with greater sensorial acceptance. For this purpose, three mayonnaise formulations (10%, 12.5% and 15% of the concentrated tucupi) were developed and submitted to sensorial acceptance and purchase intention tests. Based on the results of acceptance test by Tukey's test (p ≤ 0.05) and internal preference mapping by principal component analysis (PCA), the formulation with 10% of the tucupi was chosen. The purchase intention test showed that 95% of the judges would buy this product, which presented 41.52% moisture, 2.06% ashes, 43.95% lipids, 4.56% proteins, 3.12% total sugars, 1.51% starch, 1.29% chlorides, 9.40 µg/g β-carotene and energy value of 432 kcal/100 g. According to rheological analysis, the mayonnaise with 10% of the tucupi presented pseudoplastic fluid-like behavior and evidenced hysteresis (showing thixotropic characteristic) between the up-ramp and downramp flow curves from 60°C. The Herschel-Bulkley model was efficient in predicting product flow curve and an Arrhenius-like equation estimated activation energy value for the product (8.29 kJ/mol). Thus, the tucupi-added mayonnaise can be considered an excellent and promising alternative for the food industry. Mayonesa adicionada con tucupí: caracterización, evaluación sensorial y comportamiento reológico RESUMEN El presente estudio se propuso elaborar una mayonesa adicionada con tucupí y evaluar las características fisicoquímicas y el comportamiento reológico a temperaturas de 20 a 70°C del producto que obtuviera mayor aceptación sensorial. Con este propósito se elaboraron tres formulaciones de mayonesa (conteniendo 10%, 12.5% y 15% de concentrado de tucupí) y se las sometió a pruebas de aceptación sensorial e intención de compra. A partir de los resultados de la prueba de aceptación, que se llevó a cabo mediante la prueba de Tukey (p ≤ 0.05) y el mapeo de preferencias interno efectuado por análisis de componentes principales (PCA), se eligió la formulación elaborada con 10% de tucupí. La prueba de intención de compra mostró que 95% de los jueces compraría este producto, en el que se identificaron las siguientes características: 41.52% de humedad, 2.06% de cenizas, 43.95% de lípidos, 4.56% de proteínas, 3.12% de azúcares totales, 1.51% de almidón, 1.29% de cloruros, 9.40 µg/G β-caroteno y un valor energético de 432 kcal/100 g. A través del análisis reológico se constató que la mayonesa que contenía 10% de tucupí presentó un comportamiento similar al de un líquido seudoplástico, además de una histéresis evidente (que muestra la característica tixotrópica) entre las curvas de flujo de la rampa ascendente y la rampa descendente de 60°C. El modelo de Herschel-Bulkley resultó eficiente para predecir la curva de flujo del producto, estimándose el valor de la energía de activación para el producto (8.29 kJ/mol) mediante una ecuación similar a la de Arrhenius. Por lo tanto, la mayonesa adicionada con tucupí puede considerarse una excelente y prometedora alternativa para la industria alimentaria.
