Formula Design and Technology of Infant Formula Milk

Based on the requirements of GB10765-2010 for infant food and the sensory evaluation standard,the formula of infant formula milk was designed. Compared to the commercially available infant formula milk powder(Wyeth SMA GOLD paragraph 1 and NestleNAN.H.A.1),our formula milk state was pretty stable,and the color of milky white was more popular. By measuring the kinetic instability(TSI value)and the size of the fat globules,it was found that the product had the best fat stability under the preheating at 50℃ and the homogenization pressure of 25 MPa. A dynamic curve of the shelf life was fitted between different storage temperatures and TSI values,and the shelf life of the product at 4℃ was 53 days by calculating the acceleration ratio.
