PROJECT  
Scientific investigations involving laboratory testing and collecting information from other sources A 
few suggested Projects.  
• Study of the presence of oxalate ions in guava fruit at different stages of ripening.  
• Study of quantity of casein present in different samples of milk.  
• Preparation of soybean milk and its comparison with the natural milk with respect to curd formation, 
effect of temperature, etc.  
• Study of the effect of Potassium Bisulphate as food preservative under various conditions (temperature, 
concentration, time, etc.)  
• Study of digestion of starch by salivary amylase and effect of pH and temperature on it.  
• Comparative study of the rate of fermentation of following materials: wheat flour, gram flour, potato 
juice, carrot juice, etc.  
• Extraction of essential oils present in Saunf (aniseed), Ajwain (carum), Illaichi (cardamom).  
• Study of common food adulterants in fat, oil, butter, sugar, turmeric power, chilli powder and pepper. 
Note: Any other investigatory project, which involves about 10 periods of work, can be chosen with the 
approval of the teacher.
