RESUMO
This literature review explores cutting-edge microencapsulation techniques designed to enhance the antimicrobial efficacy of essential oils in dairy products. As consumer demand for natural preservatives rises, understanding the latest advancements in microencapsulation becomes crucial for improving the shelf life and safety of these products. The bibliometric analysis utilized in this review highlighted a large number of documents published on this topic in relation to the following keywords: essential oils, AND antimicrobials, AND dairy products, OR microencapsulation. The documents published in the last 11 years, between 2013 and 2023, showed a diversity of authors and countries researching this topic and the keywords commonly used. However, in the literature consulted, no study was identified that was based on bibliometric analysis and that critically evaluated the microencapsulation of essential oils and their antimicrobial potential in dairy products. This review synthesizes findings from diverse studies, shedding light on the various encapsulation methods employed and their impact on preserving the quality of dairy goods. Additionally, it discusses the potential applications and challenges associated with implementation in the dairy industry. This comprehensive analysis aims to provide valuable insights for researchers, food scientists, and industry professionals seeking to optimize the use of essential oils with antimicrobial properties in dairy formulations.
RESUMO
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.

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.
RESUMO
Whey is a by-product of the dairy industry of great importance due to its high nutritional value, and can be used for the manufacture of fermented dairy drinks which, combined with fruit, increase the nutritional value and add characteristic flavors. Therefore, a fermented dairy beverage with caja-mango pulp (Spondias dulcis) was elaborated and its nutritional information as well as the physical-chemical stability were evaluated during storage. The results showed that the nutritional information met the requirements stipulated by the Brazilian legislation. The physical-chemical stability of the dairy fermented drink in terms of pH, acidity, syneresis and sedimentation was influenced by the storage time, possibly associated with uncontrolled factors in this study, such as the initial and final dairy culture concentration of the processed product, protein biodegradation during storage and low solids contents. It is concluded that the elaborated drink constitutes a food source of several nutrients, and may complement the daily diet of children, adolescents and adults, supplying nutritional deficiencies.(AU)
O soro lácteo é um subproduto da indústria de laticínios de grande importância devido ao seu alto valor nutritivo, podendo ser utilizado para fabricação de bebida láctea fermentada que, associada a frutas, aumenta o valor nutricional e agrega sabores característicos. A partir disso, foi elaborada uma bebida láctea fermentada adicionada de polpa de cajá-manga (Spondias dulcis), sendo avaliada sua informação nutricional bem como a estabilidade físico-química, durante o armazenamento. Os resultados mostram que a informação nutricional atendeu os requisitos estipulados pela legislação brasileira. A estabilidade físico-química da bebida, quanto aos parâmetros analisados de pH, acidez, sinerese e sedimentação, sofreu influência pelo o tempo de armazenamento, possivelmente, associados a fatores não controlados neste estudo como a concentração de cultura láctea iniciadora e final do produto elaborado, a biodegradação de proteínas durante a estocagem e baixos teores de sólidos. Conclui-se que a bebida elaborada constitui um alimento fonte de diversos nutrientes, e poderá complementar a alimentação diária de crianças, adolescentes e adultos, suprindo as carências nutricionais.(AU)
