A fermented milk drink with Umbu (Spondias tuberosa) pulp and whey is effective for weight gain and re-nutrition in malnourished: An in vivo study in mice and children.

Malnutrition is considered one of the major public health problems worldwide and negatively affects the growth, development and learning of schoolchildren. This study developed and evaluated a fermented milk drink with added Umbu (Spondias tuberosa) pulp in the weight gain and renutrition of mice submitted to malnutrition by calorie restriction, and in malnourished children. The supplementation with this fermented milk drink contributed to an increase of 7.2 % in body weight, and 64.3 % in albumin, and a reduction of 35 % in cholesterol in malnourished mice. In humans, a group of nine malnourished children consumed a daily 200 mL serving of the milk drink (for 60 days). For humans, the fermented milk drink allowed an increase of 16.5 % in body weight, and 20.9 % in body mass index in malnourished children. In conclusion, fermented milk drink has a positive effect on the re-nutrition of malnourished mice and helps to improve the nutritional status of malnourished children.

New formulations of fermented milk drinks with fruit pulp added: Physicochemical characteristics during storage and nutritional profile

The aim of this study was to evaluate the nutritional profile and the physicochemical characteristics during storage of newly developed formulations of fermented milk drinks with added pineapple, mango and passion fruit pulp. The fermented drinks showed a high content of protein, iron, and calcium. The passion fruit milk drink had the lowest pH (4.13) and highest acidity (0.95%, expressed in % of lactic acid), which was significantly different (p<0.05) from the pineapple and mango drinks. As for syneresis and sedimentation, the pineapple milk drink had the highest rates at 14 days storage, with 34.33% and 6.50%, respectively and was significantly different (p≤0.05) when compared to the mango and passion fruit milk drinks. In conclusion, newly developed fermented milk drinks with added fruit pulp were a source of several nutrients. We observed physical-chemical characteristics suitable for a fermented milk product during storage.

El objetivo de este estudio fue el desarrollo de nuevas formulaciones de bebidas lácteas fermentadas adicionadas de piña, mango y maracuyá, para evaluar el perfil nutricional y las características fisicoquímicas durante el almacenamiento. Las bebidas fermentadas mostraron un alto contenido en proteínas, hierro y calcio. En cuanto a las características fisicoquímicas durante el almacenamiento, la bebida láctea de maracuyá presentó el pH más bajo (4,13) y la acidez más alta (0,95%, expresada en % de ácido láctico), con una diferencia significativa (p < 0,05), en comparación con las bebidas de piña y mango. En cuanto a sinéresis y sedimentación, la bebida láctea de piña presentó los mayores índices a los 14 días de almacenamiento, con 34,33% y 6,50%, respectivamente, y con diferencia significativa (p ≤ 0,05) al compararla con las bebidas lácteas de mango y maracuyá. En conclusión, las bebidas lácteas fermentadas con adición de pulpa de fruta son una fuente de varios nutrientes, y de características físico-químicas adecuadas para un producto lácteo fermentado durante el almacenamiento.
