Where can I find out how food wrapping affects spoilage?

Answer 1

Some sources say that plastic and other wrappings actually speed up spoilage because they hold in air, but for the most part packaging slows food spoilage. The functions of packaging include acting as a barrier against microbial, physical and chemical protection.

Physical: - e.g. cardboard stops bruising of fruits, therefore preventing enzymic degradation of the flesh.

Microbial: Perhaps the most important aspect of food preservation. Packaging such as plastic or metal can prevent the entry and growth of microorganisms that break down food components and cause off smells and bad textures. For example, plastic wrapping over a half-eaten steak prevents entry of microbes that break down proteins and fats.

Chemical: Light and oxygen can causes damage to food by increasing the incidence of rancidity (e.g. autooxidation [fat breakdown]) and vitamin degradation (for example riboflavin in milk breaks down it the presence of sunlight). This is why most milk bottles are opaque and gas-impermeable, which means Oxygen can't come in. Another example is cellulose film wrapping of bread, which prevents staling by stopping sntry of oxygen.

Answer 2

That is one tall order!

I suggest you narrow the scope to certain types of packaging. Then you can contact manufacturers or suppliers of the packaging and request information on studies they have done - or have access to. You can also check archives of packaging magazines or websites - like packworld.com, Food & Beverage Packaging, myfoodandpackaging.com and dairyreporter.com.

One organization you might reach out to would be The Institute of Food Technologists. They could give you some guidance.

Answer 3

The kind of food wrappings that probably affect spoilage on apples, I would have to say are, plastic wrap, and plastic container.

Answer 4

Plastic Wrap keeps your food fresher for longer periods of time because it keeps air out. Exposure to air can make your food rot faster.

Answer 5

Food Wrappings Affect Spoilage because of the air and different types of bacteria.
