Active Intelligent Packaging for Enhancing Food Quality and Safety
Active Intelligent Packaging (AIP) is a contemporary packaging technology that acts beyond protection, storage, and transportation of food. Unlike traditional packaging methods, AIP systems are designed to interact with the packaged products and alter their environment in real-time. This ensures that the food remains fresh for an extended period by increasing its shelf life while maintaining quality.
How Active Intelligent Packaging Works
AIP works by monitoring changes in the internal or external environment of the product through built-in sensors. These sensors collect data such as temperature, moisture content, pH levels, gas concentration among other factors relating to food spoilage. The collected data triggers a specific response from incorporated smart materials that make up the AIP system.
Benefits of Using Active Intelligent Packaging in Food Industry
- Prolongs the shelf-life of food products
- Minimizes food waste
- Maintains freshness and quality of packaged goods
- Cuts down costs associated with refrigeration
Different Types of Active Intelligent Packaging Systems include:
- Oxygen scavengers which reduce oxygen levels thereby inhibiting microbial growth,
- Gas emitters which release different gases like carbon dioxide within a package for respiratory control,
- Biosensors which react to changes in odor or color indicating deterioration,
- pH indicators which signal acidic conditions harmful to microorganisms living on foods making it less hospitable,
Examples of Successful Implementation of Active Intelligent Packaging:
Intelligent Plastic Water Monitoring Label: This is implemented using multiwalled carbon nanotubes that detect hazardous chemicals in water and changes the color of the label. This is used to monitor heavy metal concentration levels when packaging bottled drinking water.
- SmartFresh System: This is an ethylene regulation system embedded in packages that regulate the ripening process of fresh produce like fruits and vegetables, thus prolonging shelf-life considerably level
AIP technology has positively impacted food industries by ensuring high-quality products, reducing food waste, and increased profit margins through extended shelf life.
Components of Active Intelligent Packaging
Active intelligent packaging is a type of packaging that interacts with the products inside it to preserve their quality and freshness. The following are some common components found in active intelligent packaging.
- Oxygen scavengers are used to remove excess oxygen from the package, which can help prevent spoilage and extend shelf life. Examples of oxygen scavengers include iron-based absorbers and ascorbic acid-based absorbers.
- For instance, when coffee beans are packaged with an oxygen scavenger, it can keep the coffee fresh by absorbing any excess oxygen inside the package that could cause oxidation and staleness.
- Moisture absorbers are used to reduce humidity levels in packages that contain moisture-sensitive products like electronics or pharmaceuticals. Some commonly used moisture absorbents include silica gel pads and clay desiccants.
- A packet of silica gel often accompanies new shoes because it reduces moisture preventing shoe odor causing bacteria growth.
- Ethylene gas acts as a ripening agent for fruits, vegetables, and flowers during shipping, storage or transport resulting in quick decay or spoilage. Ethylene-absorbing materials may be utilized along with liners which will protect fruit produce from damage while slowing down ripening process:
- An activated carbon sachet placed inside sealed plastic wrap container prolongs food product storage capacity minimizing potential wastage costs thus saving both money and the environment at large.
Note: Citrus fruits emit ethylene gas potentially hastening decay for other produce items such as greens.
- Temperature indicators use a built-in thermometer or heat-sensitive ink to display whether the product inside has been exposed to temperatures outside of their safe range. This helps you determine whether the product is still safe to consume.
- A medical vaccine, which cannot be too warm or too cold during transport. Temperature monitoring labels that change color alert anyone along its shipping path if it’s above tolerance levels, ensuring safe usage during immunization programs worldwide.
Note: In the food and beverage industry getting refrigeration right is key in keeping your business running, there are several configurations available for temperature indicating devices such as battery-powered and non-battery powered units.
- Time-temperature indicators are similar to temperature indicators but also include time as a factor. These indicators track how long a product has been exposed to high or low temperatures outside of its optimal range and indicate when it’s no longer safe to consume.
- The United States Army Research Institute of Environmental Medicine developed small adhesive tags that stores can attach directly onto each meal pack served on combat deployments making sure ready-to-eat foods were kept below 80°F degrees ensuring fast preparedness daily mission deployment.
Note: Packaged fish needs an indication of freshness known by catch date at sea since it starts deteriorating after 4 days from catching up until for about 10 days with frozen fish maintaining excelling taste texture over extended periods fridge before consumption (approx.: 35°F).
- A gas sensor is used to detect the presence of gases like carbon dioxide in food packaging. High concentrations of carbon dioxide can help prevent the growth of bacteria and mold, extending shelf life. Packaged food products can have different oxygen levels monitored through packages with gas sensor properties.
Note: Modified Atmosphere Packaging (MAP)method is used for packaging perishable goods that use varying concentrations of nitrogen or oxygen to preserve meat, vegetables or fruit from quickly spoiling with these customized gas levels controlled with film gauges embedded within.
Applications of Active Intelligent Packaging
Active intelligent packaging has revolutionized the way food is packaged, stored and transported. It creates an environment for packaged products that extends their shelf life and maintains their quality by actively monitoring and controlling various environmental factors such as temperature, humidity, light, gas composition, etc. Here are some applications of active intelligent packaging in different industries:
- RipeSense: It’s a sensor-based technology that can detect the ripeness of fruits such as avocados, mangos, papayas, etc., to ensure they are delivered at peak freshness.
- ColdMate: This technology monitors the temperature of fresh produce during transportation to prevent spoilage due to exposure to high or low temperatures.
Meat and Poultry
- OxyGuard: This type of active packaging prevents meat from turning brown by absorbing excess oxygen which causes oxidation.
- Natural antimicrobial coatings: These coatings help in inhibiting the growth of bacteria on raw meats and poultry. For example: chitosan coating on chicken meat reduces bacterial growth rate significantly minimizing spoilage.
- Germicidal UV-C Light Packaging: This technique uses UV-C light technology within seafood packaging to inhibit microbial growth keeping fish edible for a longer time while maintaining its texture without degrading its nutritional benefits.
- Lactobacillus Acidophilus Microencapsulation: The Lactobacillus acidophilus microencapsulation is one method used where probiotic bacteria like lactobacillus acidophilus, an essential ingredient in yogurt and cheese is microencapsulated to ensure its survival during storage and transportation.
- Freeze-Drying: This process removes moisture from the food, ensuring a longer shelf life without compromising on quality.
- Microwave-Assisted Thermal Sterilization: This technique uses a combination of microwave heating and pressurized hot water to sterilize packaged meals while maintaining their nutritional value and taste.
- Aroma Preservation: Packages that provide aroma preservation capabilities enable companies to maintain their products’ flavors for longer periods by incorporating oxygen barrier materials in their package designs to preserve the aromas from getting lost or oxidized.
- Temperature Indicators: Sensors like Temperature indicators, when incorporated into packages, can detect temperature fluctuations giving insight into whether their products are encountering temperature abuse issues during shipment/storage thereby minimizing the need of many trials for testing.
