FOOD QUALITY ATTRIBUTES OF LOW-FAT MILK POWDER OR SKIM MILK POWDER

Low-fat milk powder or Skim Milk Powder (SMP) is produced as a result of the removal of milk fat and water from milk. It contains a maximum of 1.5% fat and a maximum moisture content of 5%. The quality of this product is determined by the total heat treatment (i.e., temperature and time of all operations in processing). Most of the properties mentioned (solubility, water content, flavour, color and others) are strongly affected by the intensity of the applied heat treatment. The storage time and the temperature influence the entire quality of the powder. SMP has low bulk density; an increase in bulk density is accompanied by a corresponding improvement in other quality characteristics such as wetting, sinking, and dispersing abilities. 

ATRIBUTOS DE CALIDAD ALIMENTARIA DE LA LECHE EN POLVO BAJA EN GRASA O LA LECHE DESNATADA EN POLVO

La leche en polvo baja en grasa o la leche en polvo desnatada se produce como resultado de la eliminación de la grasa y el agua de la leche. Contiene un máximo de 1,5% de grasa y un contenido máximo de humedad del 5%. La calidad de este producto está determinada por el tratamiento térmico total (es decir, la temperatura y el tiempo de todas las operaciones en el procesamiento). La mayoría de las propiedades mencionadas (solubilidad, contenido de agua, sabor, color y otras) se ven fuertemente afectadas por la intensidad del tratamiento térmico aplicado. El tiempo de almacenamiento y la temperatura influyen en toda la calidad del polvo. La leche en polvo desnatada tiene baja densidad aparente; un aumento en la densidad aparente va acompañado de una mejora correspondiente en otras características de calidad tales como capacidad de humectación, hundimiento y dispersión.

ПИЩЕВЫЕ СВОЙСТВА ОБЕЗЖИРЕННОГО СУХОГО МОЛОКА 

Сухое обезжиренное молоко (СОМ) производится в результате удаления из молока молочных жиров и воды. Оно содержит максимум 1,5% жира и не более 5% влаги. Качество этого продукта определяется температурой термической обработки и временем, потраченным на данные операции. Большинство свойств, таких как растворимость, содержание влаги, аромат, цвет и др, сильно зависят от интенсивности применяемой термообработки. Время хранения и температура влияют на качество порошка в целом. СОМ имеет низкую насыпную плотность; увеличение объемной плотности сопровождается соответствующим улучшением других качественных характеристик, таких как смачиваемость, подружение и растворимость.

WHOLE MILK POWDER consists mainly of whey proteins (almost 4%), caseins (almost 20%), milk fat (almost 26%), and lactose (almost 38%). The particles of milk powder consist of a continuous mass of amorphous lactose and other low-molar-mass components in which fat globules and proteins are embedded. The physical processes, involving mainly milk fat and lactose, together with chemical reactions, have the ability to reduce the shelf life of WMP and other dry products based on milk powder. These other products include infant formula and instant powders for coffee, cocoa, and chocolate-flavored beverages. Long-term storage of milk powder affects the nutritive value, mainly due to loss of lysine, and the sensory qualities of the reconstituted milk, as well as the functional and physical properties that are so important for the use of milk powder as a food ingredient. Milk powder quality is influenced by various factors during processing or storage: 1. Manufacturing techniques and parameters 2. Drying techniques and conditions 3. Storage conditions Three deteriorative reactions determine the shelf life of milk powder in practice: lactose crystallization, lipid oxidation, and Maillard reactions (nonenzymic browning). The basic properties that determine milk powder quality, and where defects mainly appear, include powder structure, solubility, water content, scorched particles, owability, oxidative changes, avor, and color. Hence, milk powder quality should be quantified by the relationship between the perational process variables that best describe these properties.
