How Safe is it to Cook With Plastic Bags?

A quick online search on how to cook sous vide dishes would reveal that this French cooking methodology involves the use of plastic bags. A prevalent concern that comes from this cooking technique is the effects of the utilization of plastic at high temperatures. Many researches have concluded that plastics that are safe to use with food preparation are such as polypropylene, low-density polyethylene, and high-density polyethylene.

Polyethylene, in particular, has been widely studied and tested for their safety when used in preparing dishes. As many chefs advocate, bulk plastic wraps that are relatively less expensive decompose into harmful plasticizers upon exposure to high temperature. Furthermore, they have been shown to leach into fatty foods such as fish, meat and cheese. A ‘bad’ plastic, such as polycarbonate will release an unhealthy chemical known as BIsphenol A (BPA) when exposed to high temperatures. This chemical has been known to disrupt hormone activity when consumed by human beings.

An easy method to differentiate between these harmful plastics and plastics that are suited for sous vide cooking is by inspecting the plastic for a rating that proves it is microwave-safe. It should be noted that wraps and plastic bags made from polyethylene are generally speaking, microwave safe. In addition to this, it should also be known that plastics that are made from polyvinyl chloride are unsafe for use in food preparation.

In conclusion, plastics made for getting started with sous vide cooking are entirely safe. This is in addition to common ziplock bags, oven bags, and stretchable plastics. In conclusion, selecting a BPA-free plastic made from polyethylene proves to be vital when cooking via sous vide.
