This document proposes research into developing an edible food packaging film made from soybean polysaccharide using a blown-film extrusion method. Over 1 billion tons of food are wasted globally each year, which could be reduced through advanced packaging technologies like edible films. Existing SSPS edible films have a short shelf life and are produced at a small scale using solution casting. The proposed research aims to optimize concentrations of cinnamon essential oil and glycerol additives in SSPS films for antimicrobial properties and quality using blown film extrusion, which could enable large scale production. The expected outputs are an efficient manufacturing process for an edible film with antimicrobial properties that extends food shelf life and reduces waste.

2. Problem Definition
According to an estimate of Food and Agriculture Organization, about 1.3
billion tons of food are globally wasted or lost per annum. In India, the food
waste accounts for ₹ 92,651 crore which is roughly equivalent to 0.6% of
gross domestic production. This food wastage can be reduced by using
advanced processing and packaging technologies such as edible packaging.
Research gap
To date, Soluble Soybean Polysachharide (SSPS) based edible film has
been manufactured using solution-casting method only which is having
short shelf life. Further, there is a need of a method that can be used for an
industrial scale production of edible film.
Rationale
An increase in the cost of petroleum, awareness of environmental issues,
and international regulatory pressure banning biodegradable plastics
inpackaging applications has promoted the development of non petroleum
based materials and biodegradable packaging.

3. Research question
Can blown-film extrusion method be efficient for large scale
production of antimicrobial and biodegradable soybean
polysaccharide based edible food packaging film?
Hypotheses
Developed edible film is expected to provide a wide
antimicrobial spectrum that could inhibit the growth of
different food spoilage and extend the shelf life of food.
Further, the film will be edible and biodegradable in its nature.

4. Research Objectives
1) To develop antimicrobial SSPS based edible food packaging films at
different concentrations of cinnamon ceylan (Cinnamomum verum L.)
essential oil, and glycerol as plasticizer using blown-film extruder.
2) To optimize the concentrations of cinnamon ceylan essential oil and
glycerol in SSPS based film with the response parameters as antimicrobial
activity, physical, barrier, mechanical, thermal, optical and microstructural
properties.
3) To test the potential of blown-film extrusion process for large scale
production of optimized formulation/conditions.
Expected Output
Highly efficient manufacturing of edible packaging film with a wide
antimicrobial spectrum which is biodegradable in nature.
Expected Outcome
Edible food packaging film could contribute to food security by extending
the shelf life and enhance food quality which may further reduce global
packaging waste

5. Activities
Activity 1: Design of experiments using Design Expert Software
Activity 2: The extrusion experiments will be performed using a co-rotating
twin-screw extruder to form pallets which will be formed into films by
using blown-film extruder.
Activity 3: Determination of physical, thermal, mechanical, optical and
microstructural properties of the developed films.
Activity 4:Optimization of concentration of cinnamon ceylan essential oil
and glycerol using Response Surface Methodology (RSM)
Activity 5: Development of pilot scale plant
Activity 6: Demonstration of working of the plant to obtain high quality of
edible packaging film
Key words
