Abstract
Infant milk formulae are used as breast milk substitutes whereby the moisture content
determination is crucial and important to prevent the infection via foodbome pathogenic
bacteria. Water or moisture content in milk powder can affect product quality, texture, shelflife,
chemical stability, reactivity of foodstuffs and increase the microorganism activity in
infant milk formulae. In this work, moisture content analysis of the two infant milk formulae
labelled as the samples A and B which stored in different household conditions and packaging
materials have successfully been conducted using Karl Fischer (KF) titration technique.
Throughout the work, the samples were analysed during freshly open, after one week, and
after two weeks stored in different household conditions at different temperatures and storage
packaging materials. The finding shows that there are significant changes on moisture content
of the samples when stored in different household conditions at different temperatures and
packaging materials. The longer the storage time, the higher the moisture content in infant
milk formula. The results show that the most suitable household storing condition to store the
infant milk formula is in the refrigerator where infant milk was put in closed storage
container. The most suitable type of storing packaging material is in glass bottle.
