5 Questions
Explain the advantages of using starch-based film for edible packaging in noodle cups.
Starch-based film is advantageous due to its abundance as a natural polysaccharide raw material, renewability, cost-effectiveness, and wide availability.
Describe the process of making starch film for edible packaging in noodle cups.
Starch film is made by disrupting the crystalline structure of starch when heated in water, leading to the interaction of water molecules with amylose and amylopectin hydroxyl groups and the formation of a homogenous solution to create the film.
What are the two main techniques for obtaining edible or biodegradable starch films?
The two main techniques are solution casting and subsequent drying (wet method) and thermoplastic processing (dry method).
Explain the physicochemical properties of the structure of starch biopolymers in edible packaging.
The structure of starch biopolymers is semi-crystalline, containing both amorphous and crystalline zones, characterized by the glass transition temperature and the degree of crystallinity.
Why is the glass transition temperature (Tg) considered an important parameter in determining the mechanical properties of starch-based film?
The Tg is crucial for determining the mechanical properties because it indicates the transition from a hard, glassy state to a rubbery state in the starch-based film, influencing its performance and behavior.
