Abstract : Bottle bevarages filled Polyethylene Terephthalate (PET) bottle are in demand for drinkable bottle due to excellent characteristic such as neligible permeability to carbon dioxide, can withstand high temperature, non-toxic nature, high mechanical strength and high transparency. New developed formulation can be made to impart degradable properties to PET. Research was carried out by using masterbatch of degradable Polyethylene Terephthelate (PET) and they are blow moulded through injection blow moulding technique. Chemical content of filling liquid such as mineral water and coke were investigated through Biochemical Oxygen Demand test and uv-visible test. BOD values for each sample in different exposed condition were determined to investigate the presence of bacteria on the bottle. Test was carried out by taking the initial value (before exposed at different condition) of two type of water which is mineral water and carbonate drink. Result showed that mineral water has highest BOD value compared to carbonated drink which is 7.56 mg/L and 1.32 mg/L respectively. Liquid were tested at three different conditions which are at room temperature, exposure to sunlight and in fridge for four week and result was taken. BOD exhibited lowest value for fridge storage beverages. It shows that BOD depends on the temperature of storage or exposure; lower temperature can inhibit microorganism growth. UV-Visible spectroscopy as used to investigate the amount of aldehyde and ketones group in the beverage that had been exposed at different exposed condition. No appreciable UV absorption between 280 to 200nm of liquid was found for room temperature and fridge condition PET sample as compared to sunlight exposed. UV absorption started to develop significant absorption after 2 weeks whereas fridge and room temperature only showed negligible absorption even after 4 weeks. Keywords— Polyethylene Terephthalate (PET), Biochemical Oxygen Demand (BOD), UV-Visible Spectrometer Analysis.
