Abstract:Infant formula is based on the growth needs of infants, the nutritional content of breast milk as simulation, inadequate or lack the time when the breast, specifically for the baby's main food.Whey protein α-lactalbumin with, β 1 lactoglobulin, serum albumin, immunoglobulin and other proteins, nutritional value. However, whey proteins are heat-sensitive protein, heat denatured soluble in water decreased, so that the use of whey protein range is greatly restricted. The experimental task is to whey protein is whey peptides by biodegradable after use in infant formula milk powder. In the laboratory a simple infant formula, a preliminary exploration of its processing technology. Also familiar with and master the principles and operation of spray drying method.Whey peptides with an alternative infant formula in WPC80, the indicators in line with national standards in the premise of a preliminary compatibility, and master the process of process parameters. Repeated the experiment to optimize the process parameters.After repeated experiments, the final parameters are determined: Weigh 200 grams of raw materials, allocation of reconstituted milk concentration of 10%, the temperature was 190 ℃, exhaust air temperature is 90 ℃. Alternative basic data and parameters of the experiment, the first extension of the infant formula with the design of the data obtained in the experiment, further substitution experiments found that formula milk powder out of good quality and less coking phenomenon.
Key words: Milk; Milk formula; whey peptides; process parameters
