Light-induced degradation reactions make a serious problem for the milk because of the development of flavors and a decrease in nutritional quality, materials of Packaging are important to avoid this particular degradation of milk. In this study, were divided milk into two groups  (light exposed ) + (light protected  (foil overwrap))  under the same cooling conditions at 3°C  for 15 days, those expectant during the show in stores of retail and markets. And the effect of this on the chemical composition of milk, the results of my study then showed that the appropriate blocking light with an overwrap of foil helped inhibit lipid and protein Lipolysis compared with the samples exposed to light under the same cooling conditions. Therefore, the appropriate Blocking of visible light with foil overwrap can increase milk's shelf life.
