Stress is both a physical response that protects us and a natural defence mechanism that allows us to survive. However, overstressing may lead to serious illness. This paper emphasizes on the stress detection via amylase enzyme in one's person saliva. Since salivary amylase is a digestive enzyme, changes are expected in its activity and be associated to the levels of stress. The analysis of amylase enzyme on one's saliva has been done using a photometer; to measure the light intensity of the chemical reaction when Lugol's iodine, starch solution and salivary amylase are added together. The outcome indicates that this Amylase Enzyme Detection System has proved to be the simple, portable and cheap device using GUI and stopwatch designed in MATLAB. Further investigation will look onto the behaviour and characteristics of the salivary amylase using other promising technique
