Applications of biopolymers as environmental friendly. The material use a lot is starch. Starch is cheap, readily available.
• Starch is a natural polymer derived from parts of plants, good biodegradability as well as low cost.
• Starch films exhibit lower mechanical properties and higher permeability for gases and water vapor but can improve by Interaction of nanofillers and glycerol plasticized.
•The color of indicator is used to correlate the spoilage of product
• The development of smart packaging in from of food spoilage indicator to monitor freshness status of food products
