DETAILED DESCRIPTION
The various embodiments and the other advancements and features are illustrated with the reference to the non-limiting details in the following detailed description. The various embodiments of the invention propose a novel food packaging system utilizing self-healing polymers to ensure food safety. By employing a combination of intrinsic (sodium alginate/chitosan) and extrinsic (gelatin extract/green tea) polymers, the packaging can effectively repair itself upon damage, preventing contamination and preserving food quality.
Self-healing properties represent a remarkable advancement in science, it provides the material to repair themselves automatically after damage. These properties extend the lifespan of the material and reduce the maintenance.
This self-healing food packet as two layers the first layer which is outside the food packet is extrinsic layer and the second layer which is after the extrinsic layer or inside the self-healing food packet is intrinsic layer.
The self-healing property repairs microcracks before they can propagate, which prevents fatigue and extends the lifespan. since it can repair itself, there is less need for frequent repairs or replacements, reducing costs and waste.
Sodium alginate derived from seaweed. It is a natural polysaccharide that forms a gel-like structure when it is combined with water or specific ions. The structure it forms is flexible making it an excellent choice for a barrier that can conform to food items by offering protection from external contaminants.
When the layer is damaged it undergoes oxidation producing aldehyde groups. It creates a cross-linked structure in it. This structure helps to repair the tears, cracks and to restore the barrier for maintaining the food protection.
Sodium alginate is edible and also biodegradable, this provides eco friendliness and also, it provides safety to the food packets. It decomposes in the environment without harming it.
Chitosan, it is derived from the shells of the crustaceans, it has strong antimicrobial properties; it adds a layer of defense against foodborne pathogens and spoilage microbes. Which helps to keep the food safe and extends the shelf life of the food items by reducing microbial contamination.
Chitosan is a durable, flexible biopolymer these contributes to the structural integrity of the intrinsic layer. It creates a tight network within the layer providing a resistance to environmental stresses, such as temperature changes and moisture.
When it combines with sodium alginate it provides a self-healing property. When the intrinsic layer is damaged, chitosan provides crosslinking reactions which restores the layer, thus maintaining the food protection.
While combining the sodium alginate and chitosan it creates a strong, self-healing and also antimicrobial barrier which helps to maintain the food safety, freshness and quality of the food throughout transportation and storage.
Intrinsic layer made up of Sodium alginate and chitosan with a width of 8mm it forms a self-healing polymer. sodium alginate, derived from brown algae, and chitosan, obtained from crustacean shells, are both biodegradable polymers.
When combined, they form a hydrogel with self-healing properties. The interaction between sodium ions in sodium alginate and amino groups in chitosan leads to reversible cross-linking. Promotes cross-linking by adding calcium Ions.
Gelatin is a natural biopolymer derived from collagen, which forms a flexible yet strong film that can act as an effective physical barrier against external elements. Its structure allows it to create a cohesive layer that prevents the external particles from penetrating the food package.
It can also provide self-healing property with green tea extract, when it reacts with this substance, it forms a bio-hydrogel that repairs the damage and seals the tear, it maintains the integrity of the food. gelatin is fully biodegradable thus it can decompose naturally without the environment is harmed and contributing an Eco friendliness of the package.
Green tea extract contains polyphenols and maximum of catechins, which have natural antimicrobial and antioxidant properties. These properties help to protect the food inside by inhibiting the growth of bacteria and fungi which causes spoilage.
These properties in the green tea extract prevent the oxidation of the food inside the self-healing food packets. Which can lead to degradation in quality, flavor. It is mostly preferred for frozen food items. Likewise, gelatin extract it also maintains the integrity of the food.
While combining the gelatin extract and green tea extract it creates a strong, selfhealing and also antimicrobial barrier which helps to maintain the food safety, freshness and quality of the food throughout transportation and storage.
The Extrinsic layer made up of Gelatin Extract and Green tea Extract with a width of 6mm it forms a self-healing polymer, gelatin derived from animal collagen, and green tea extracts have been investigated for their self-healing potential.
These natural materials can form networks that allow for reversible bonding. When the material is damaged, these bonds can break and reform, effectively repairing cracks and maintaining structural integrity. When any of the layer is torn or damaged, the reversible bonds within the polymer network can reform. This process effectively repairs cracks and maintains the structural integrity of the packaging. It creates a Sealing in the Packets that prevents contamination and the Food quality is maintained for longer period and prevents spoilage. By the usage of biodegradable polymers, reducing the environmental impact of plastic packaging.
Thus, the quality of the food stored inside the self-healing food packet is notably increasing its quality and preserved due to the advanced properties of the packaging.
