There have been fears regarding the use of plastics in sous vide, so is it a safe technique?
Let’s look into some of the concerns raised.
In the recent past, there have been studies that indicate that most plastics include some that are BPA-free, can leach out chemicals with (EA) estrogen activity.
Most plastics such as Tupperware containers, baby bottles, plastic wraps and sandwich bags leach out chemicals.
These chemicals yield an increase in estrogen flow, this can, in turn, lead to problems like reduced sperm counts, early puberty in females, obesity, an increase in cancer cases, and issues with childhood and infant development.
After reading this part, you may be saying “I cannot sous vide anymore”! But what is the truth?
The plastic that comes into contact with your food during sous vide cooking is 100% polyethylene.
It contains no estrogen-like compound or plasticizer. Foodsaver bags are 5-layers of polyethylene, and the outer layer is nylon.
You might get BPA from some plastic cans, but you will not get any BPA from sous vide.
Also, sous vide temperatures are low (polyethylene does not start softening until 195 degrees Fahrenheit).
If it were not so, some polyethylene would still leach into your food.
However, polyethylene is biologically inert; scientists all over the world have not been able to detect any toxic elements in animal tests.
Polyethylene exceeds the Ames test and other DNA damage studies and does not have any similarity to estrogen.
The health and taste benefits that sous vide offers far outweigh all the speculated harms.
Some of the noticeable benefits of sous vide cooking include less AGE production, hindering nutrient loss, and protein degradation.
It also helps to retain more fatty acids. Since the sous vide cooking is slow, and you leave the food to cook on its own, you can handle other tasks simultaneously.
Relax now! Sous vide bags are very safe, and you can continue to enjoy the quality and creative cooking.
Foodsaver bags and sous vide supreme pouches are ideal for fast, airtight vacuum-sealing and both are free from EA-leaching and BPA issues.
These pouches/bags are fine for sous vide lovers who want to maximize food safety while minimizing preparation time.
Before choosing pouches for sous vide, make sure that they are BPA-free.
The best option is to search online for sincere reviews. Also, check what other users are saying about certain sous vide bags.
Do not purchase any pouch if you are not sure about its functioning.
