ABSTRACT

The use of fruits and their by-products in food has dramatically impacted the food industry due to the nutritional benefits and the technological and sensory effects of food matrices. Therefore, this research aimed to evaluate the effects of adding cupuassu (Theobroma grandiflorum) pulp and flour on fermented milk beverages' physicochemical, microbial, and sensory properties during refrigerated storage (0, 7, 14, 21, and 28 days). Twelve formulations were realized with different percentages of cupuassu pulp (0, 5, 7.5, and 10% w/v) and flour (0, 1.5, and 3% w/v). The treatments with 3% cupuassu flour presented the highest percentages of protein, fat, fiber, and carbohydrates, compared with the samples containing pulp. On the other hand, the addition of pulp increased water retention capacity and color parameters (L*, a*, b*, and C*) and decreased pH and syneresis on day 0 of storage. During storage, the samples with pulp showed increases in pH values, consistency index, and apparent viscosity. In comparison, cupuassu flour addition decreased syneresis values and increased L* and b* during storage, as did pulp. In addition, sample HPHF (10% pulp and 3% cupuassu flour), based on just-about-right, penalty, and check-all-that-apply analyses, improved some sensory attributes of the fermented milk beverage, such as brown color, acid taste, bitter taste, cupuassu flavor, and firm texture. It can be concluded that cupuassu pulp and flour addition improves the physicochemical and sensory quality of fermented milk beverages and can provide nutritional value to the product.

ABSTRACT

The aim of this research was to characterize a fermented yogurt-type milk drink that was elaborated from whey with the addition of aloe vera crystals and granadilla (Passiflora ligularis Juss). Four formulations for characterization were obtained: F1 (control), F2 (5% aloe vera and 15% granadilla), F3 (10% aloe vera and 10% granadilla) and F4 (15% aloe vera and 5% granadilla). Next, a sensory evaluation through a hedonic test was conducted to choose the formulation with the highest acceptance. After the best formulation was chosen, a bromatological and syneresis characterization was performed. The F4 sample had the best results in the sensory evaluation. Compared to the F1 sample, statistically significant differences (p<0.05) in all parameters except in total carbohydrates was observed for the bromatological analysis. In the percentage of syneresis, at the end of the 15 days, F4 presented a lower value in this parameter with respect to the control sample. It could be determined that the higher percentage of aloe vera and the lower percentage of granadilla had a big influence on the parameters evaluated, where it presented the best results compared to the other samples evaluated.


El objetivo de esta investigación fue caracterizar una bebida láctea fermentada tipo yogur que se elaboró a partir de lactosuero con la adición de cristales de aloe vera y granadilla (Passiflora ligularis Juss). Se obtuvieron cuatro formulaciones para la caracterización: F1 (control), F2 (5% de aloe vera y 15% de granadilla), F3 (10% de aloe vera y 10% de granadilla) y F4 (15% de aloe vera y 5% de granadilla). A continuación, se realizó una evaluación sensorial mediante una prueba hedónica para elegir la formulación de mayor aceptación. Una vez elegida la mejor formulación, se realizó una caracterización bromatológica y de sinéresis. La muestra F4 obtuvo los mejores resultados en la evaluación sensorial. En comparación con la muestra F1, se observaron diferencias estadísticamente significativas (p<0,05) en todos los parámetros, excepto en los carbohidratos totales. En el porcentaje de sinéresis, al final de los 15 días, F4 presentó un valor inferior en este parámetro con respecto a la muestra de control. Se pudo determinar que el mayor porcentaje de aloe vera y el menor porcentaje de granadilla influyeron mucho en los parámetros evaluados, en los que presentó los mejores resultados en comparación con las otras muestras evaluadas.
