Evaluation of the Chemical Quality (Fat, moisture, and acidity) of Powder Milk Sold in Open Markets in Chattogram

Abstract

The present study was performed to determine some chemical composition of powdered milks that are available in Chattogram Metropolitan area. Powder milk samples of 7 different brands named Dano, Marks, Ama, Fresh, Diploma, Greenland and Starship were collected from local market. In this study the fat, moisture and titrable acidity percentage were examined by standard methods. In this study we have found that the average fat content in powdered milk is in the range of 5.06 -26.9 %. The huge variation in fat percentage was because of having both skimmed and full creamed powdered milk in the samples. In our study the average moisture percentage of the powdered milk is within the range from 3.10 - 3.75 %. The average acidity % in our study was in the range from 0.11 - 0.15 %. This study indicates that most milk powders can considered of fair quality. The quality of milk powder sold in the market can be considered to be good for human consumption
