To preserve the milk, human milk banks (HMB) pasteurize and freeze it; nevertheless, the nutritional value of the human milk (HM) decreases during thawing and storage. This study aimed to evaluate the effect of high hydrostatic pressures (HHP) and spray-drying on macronutrients, microbiological qual...

| description |
To preserve the milk, human milk banks (HMB) pasteurize and freeze it; nevertheless, the nutritional value of the human milk (HM) decreases during thawing and storage. This study aimed to evaluate the effect of high hydrostatic pressures (HHP) and spray-drying on macronutrients, microbiological quality, and inactivation of Staphylococcus aureus on HM. The characterization of HM powder, reduction of S. aureus, modifications in microbiological viability, proteins, carbohydrates, lipids, and ashes were assessed. The findings demonstrated that while S. aureus and all other examined microbial groups were undetectable, macronutrient concentrations remained constant during the entire conservation process. High yield (> 99 %) was achieved thanks to the inclusion of soluble fiber during the drying process, and the powder that was produced displayed high solubility, low moisture content, and activity water; which are desirable properties in dried foods. Therefore, the combination of HHP and the spray-drying process is an alternative to facilitate the handling, improve the microbial quality, allow the addition of oligosaccharides, and maintain the nutritional value of HM in HMB. |

Los bancos de leche humana (BLH) utilizan la pasteurización y congelación, como principales métodos de conservación para la leche humana (LH). Sin embargo, su valor nutricional disminuye durante la descongelación y almacenamiento. El objetivo del presente estudio fue evaluar el efecto de las altas presiones hidrostáticas (APH) y el secado por aspersión sobre los macronutrientes, la calidad microbiológica e inactivación de Staphylococcus aureus en LH. Para ello, se realizó la cuantificación de proteínas, lípidos, carbohidratos, cenizas, bacterias lácticas, mesófilos aerobios, coliformes, mohos, levaduras y S. aureus. Los resultados mostraron que S. aureus y los grupos microbianos evaluados fueron reducidos por debajo del límite permitido por los BLH (<10 UFC/mL). Mientras que las concentraciones de macronutrientes permanecieron sin cambio durante todo el proceso de conservación. El uso de fibra soluble durante el proceso de secado permitió obtener un rendimiento mayor al 99 %. El polvo mostró alta solubilidad y bajos niveles de humedad y actividad en agua; las cuales son propiedades deseables en los alimentos deshidratados. Por lo tanto, la combinación de HHP y el proceso de secado por aspersión demostró ser una alternativa que facilitar el manejo, mejora la calidad microbiana y permite la adición de oligosacáridos manteniendo el valor nutricional de la LH.
