What BT611T Assignment 1 asks
This assignment explores food analysis and safety through the Kjeldahl method of protein estimation and the use of microbiological indicators in water testing. Students will examine the 2008 melamine milk scandal to understand how adulteration can exploit analytical techniques. The work requires explaining the scientific principles behind protein measurement and the role of E. coli as a fecal contamination indicator. You must provide clear explanations supported by relevant examples.
