A study on the on total color changes of fiber enriched milk tablet at different storage condition / Siti Amira Uzir

Malnutrition problems among young children and adult are incredibly serious which include inadequate consumption of fiber and milk which are also rich in nutrients to help body functions. The problems are also extremely severe in less fortunate country. Fruits and vegetables are the main source which offers abundant health benefits to human. Apart from that, this natural source of fiber contains natural pigments pigments which contribute to the attractive color of the food. Hence the breakthrough approach to encourage milk and fiber consumption in young children is by the development of fiber enriched milk tablet. The study focuses on development of fiber enriched milk tablet for ease of transportation, storage and increased shelf life. Without additional synthetic coloring additives, the objectives of the research work are to study the natural color stability of fiber enriched milk tablets upon storage. From the study done, each fiber source chosen contains different natural pigments that responsible for the tablets color. Since different fiber source contains different pigments have different which behaves differently due to their auto oxidation behavior and kinetics which requires deeper studies regarding their degradation mechanism in order to successfully determine optimum storage condition for each fiber enriched milk tablets. Based on the results obtained, every pigment shows significant value of total color changes (∆E) upon 5 days storage at different storage condition. All pigments shows significant ∆E when subjected to extreme storage temperature, light and metal ions from packaging.
