Food Packaging Quiz Questions And Answers

Glass materials can be reused and recycled, making it an effective waste reduction method. Reusing glass containers, such as bottles or jars, reduces the need for new production and helps conserve resources. Additionally, glass can be recycled multiple times without losing its quality, further reducing waste. By promoting the reuse and recycling of glass materials, we can minimize the amount of glass waste that ends up in landfills and contribute to a more sustainable and environmentally friendly approach.

Coextruded films are made by simultaneously extruding multiple layers of different materials to form a single film. This process ensures a strong bond between the layers, resulting in a film with less tendency towards delamination. On the other hand, laminated films are made by bonding multiple layers together using adhesives, which may have a higher risk of delamination over time. Therefore, the statement that coextruded films have less tendency towards delamination compared to laminated films is true.

Glass is chemically inert because it does not react with most substances. It is resistant to corrosion, does not absorb or leach chemicals, and does not release any harmful substances into the contents it holds. This makes glass a suitable packaging material for a wide range of products, including food and beverages, pharmaceuticals, and chemicals. Metal, paper, and plastics, on the other hand, can react with certain substances or release chemicals that may contaminate the contents, making them less chemically inert compared to glass.

Aseptic packaging technology fulfills the function of protection in food packaging. Aseptic packaging involves sterilizing the food and the packaging separately, and then sealing them in a sterile environment. This process helps to prevent the growth of microorganisms, maintain the quality and freshness of the food, and extend its shelf life. Therefore, aseptic packaging technology plays a crucial role in protecting the food from contamination and spoilage.

HDPE bottles for packaging of milk are pigmented to provide protection against light. Exposure to light can cause milk to undergo photooxidation, leading to the degradation of its nutritional value, taste, and quality. Pigmented bottles act as a barrier, preventing light from penetrating and thus preserving the milk's freshness and integrity.

Phthalates are a harmful component that can be found in PET bottles. These chemicals are commonly used as plasticizers to make plastic more flexible and durable. However, they can leach out of the plastic into the contents of the bottle, especially when exposed to heat or acidic liquids. Phthalates have been linked to various health issues, including hormone disruption, reproductive problems, and developmental issues in children. Therefore, it is important to be cautious when using and reusing PET bottles to minimize exposure to these harmful substances.

Ethylene absorbers are a type of active packaging that is applicable to fruits. Ethylene is a natural gas released by fruits as they ripen, and it can accelerate the ripening process and lead to spoilage. Ethylene absorbers help to remove ethylene gas from the packaging environment, thereby slowing down the ripening process and extending the shelf life of the fruits. This type of active packaging is particularly useful for fruits that are sensitive to ethylene, such as bananas, apples, and avocados. Oxygen absorbers, moisture absorbers, and carbon dioxide absorbers are not specifically designed to address the issue of ethylene gas in fruits.

The correct answer is Intelligent packaging. Based on the given options, the packaging technology applied in the picture can be identified as intelligent packaging. Intelligent packaging refers to the use of advanced technologies, such as sensors and indicators, to monitor and communicate information about the condition of the product inside the package. This allows for real-time tracking of factors like temperature, humidity, and freshness, ensuring the quality and safety of the product.

A shrink-wrapped pallet of orange juice is an example of tertiary packaging because it involves packaging multiple units of a product together for transportation and storage. Tertiary packaging is designed to protect the product during shipping and handling, and it often includes additional materials like pallets or shrink wrap to secure and organize the individual units. In this case, the shrink-wrapped pallet of orange juice serves as an outer layer of packaging that contains and protects multiple units of orange juice bottles.

Pasteurized milk should be kept at temperatures between 10 and 15 degrees Celsius to maintain its shelf life. Temperatures below 10 degrees Celsius can cause the milk to freeze, while temperatures above 15 degrees Celsius can lead to spoilage and bacterial growth. Therefore, storing pasteurized milk within the range of 10 to 15 degrees Celsius ensures that it remains safe and consumable for a longer period.

LDPE (Low-density polyethylene) is the most appropriate plastic for packing fresh red meat because it has excellent moisture barrier properties, which helps to prevent the meat from drying out and keeps it fresh for a longer period of time. LDPE is also flexible and has good puncture resistance, which ensures that the packaging does not tear easily during handling and transportation. Additionally, LDPE is resistant to chemicals and provides a good oxygen barrier, which helps to maintain the quality and shelf life of the meat by preventing oxidation.

The Temperature-Time Indicator (TTI) is a function of food packaging that communicates information about the temperature and time history of a product. It provides a visual indication of whether the food has been exposed to temperature abuse during storage or transportation, helping consumers make informed decisions about the safety and quality of the product. It does not cover containment, convenience, or protection, which are other functions of food packaging.

Flexcracks can be found on retort pouches. Flexcracks are small cracks that occur due to the repeated flexing of the pouch during transportation or handling. These cracks can compromise the integrity of the pouch and lead to leakage or spoilage of the contents. It is important to identify and address flexcracks to ensure the quality and safety of the retort pouch.
