If the water covers the can then the temp can't exceed ~100c which won't make it explode. So it's safe unless you dry scorch it.

Tin cans are lined with plastic inside and heating food in the can will cause that plastic to leach toxic chemicals into the food. It's really never safe to heat food in any kind of plastic, the shit that leaches out is associated with endocrine disruption and other problems.

It means the chemicals interfere with the function of your endocrine system which can mess up hormone production in your body.

It's all pretty hotly debated, but there's enough evidence out there about heated plastic producing endocrine disrupting chemicals that I personally steer clear of any kind of cooking in plastic.

How substantially are we talking about? I've become allergic to statements like this because the actual research could have stated something insignificant like "risk of 0.2% hormone production disruption in 2% of test subjects have been observed with a x% expected variation" which means absolutely fuck all even if it's "true" when said as an absolute statement.
It's nothing personal. I'm just tired of being misled by bold sweeping claims. I could absolutely get behind plastics fucking us up on a serious level when heated and consumed.

Don't take my word for it, just look up "plastic endocrine disruption" and you'll find plenty of information to make a decision for yourself. It's to the point now where microplastics are generally accepted to cause endocrine disruption in mammals, and now research is focusing on quantifying the extent of it. Couple that with microplastics' tendency to accumulate in the body over time and that's where the problems with cooking in plastic arise, because soft plastics break down at microscopic levels when heated and release particles and chemicals that will accumulate in your body along with all the other microplastics you're exposed to regularly. To me, it's not worth adding to the problem so I avoid cooking in plastic altogether.

Essentially all food cans are lined, the only ones that aren't are for dry stuff. You can always just dump it in a small saucepan if it's a concern.

The plastic isn't there JUST for the corrosive contents. It also keeps the content from leaking if it suffers a dent. Maybe even for other sealing properties. I wouldn't even be surprised if they simply made all plastic lined because otherwise they gotta have another machine line up for doing it without the plastic.

I had a water boiler which said it was "silent" and a year later I found out why it was quieter than others. They had lined the entire inside in an extra plastic layer over the metal casing. An expensive Kitchenaid one. They didn't even market it as BPA free. So I've been drinking boiled plastic water for over a year unknowingly.

No they aren't. The only cans with liners are for corrosive foods like tomatos or soda. All other canned foods that can be eaten straight out of the can are cooked while in the can to preserve them. So no, they wouldn't have a liner. The liner is just there to protect the can, not the consumer. It would be an unneeded cost to just add it to any can for no reason.

I can't find any resources that say only certain types of canned food use inner coatings, only ones that attribute all canned foods to having them, like this: https://www.ewg.org/news-insights/news/bpa-update-tracking-canned-food-phaseout

For clarity, the most important bit is near the bottom:
>When choosing canned goods, contact the company to ask whether it still uses BPA. If not, ask for details about the replacement – what it is, its safety profile and when the switch was made. Every can is stamped with a code that corresponds to its production date. Ask the company which codes indicate that a canned item was manufactured after the BPA phaseout.
Note it doesn't say to ask whether there's a coating, just whether the coating contains BPA and if not what other material it's made from. Every information source I've found is like this, none of them suggest types of canned foods with no coatings that might be safer, it's only ever a question of what type of plastic is used.

You can or could avoid BPA by avoiding canned food (though as other anons have pointed out they've moved onto other compounds for better or worse), but microplastics are in the water cycle now, which means they end up in crops from watering, and in meats from animal feed. I'm trying to think if there's any sort of food source that would have lower levels but aside from chemically synthesising basic carbohydrates from scratch I don't see how it would be possible.

[Anonymous No.20255663]

I'm fairly sure ruminant animal meat will always have the lowest amount of contamination because of how thoroughly they digest and filter all the food they eat before it gets stored away. It will never be free of contamination but it's better than with monogastric animal meat or plants.

The endocrine disrupting effects of microplastics is well-documented and accepted. The only question is just how bad the problem is, just how bad it could get, and how the hell we can hope to slow or stop it.
Here's some information you can find easily on any search engine:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7068600/
>Among these chemicals, many routinely used to make plastics are dangerous. Bisphenol A (BPA), phthalates, as well as some of the brominated flame retardants, that are used to make household products and food packaging, have been proven to be endocrine disruptors that can damage human health if ingested or inhaled

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10151227/
>In addition, various chemicals are used when synthesizing plastic polymers, depending on the end use, most of which are endocrine disruptors. Endocrine disruptors, also referred to as hormonally active agents, can harm the human body by causing various cancers and reproductive-system disorders. Microplastics can also affect the human body by stimulating the release of endocrine disruptors.

https://www.endocrine.org/news-and-advocacy/news-room/2020/plastics-pose-threat-to-human-health
>Conservative estimates point to more than a thousand manufactured chemicals in use today that are EDCs. Known EDCs that leach from plastics and threaten health include bisphenol A and related chemicals, flame retardants, phthalates, per- and polyfluoroalkyl substances (PFAS), dioxins, UV-stabilizers, and toxic metals such as lead and cadmium. Plastic containing EDCs is used extensively in packaging, construction, flooring, food production and packaging, cookware, health care, children's toys, leisure goods, furniture, home electronics, textiles, automobiles and cosmetics.

If you're thinking of heating a can long enough for it to turn into dulce de leche, have you considered just making dulce de leche from scratch? Coincidentally, I made it for the first time, last night, and, while time consuming, it wasn't technically difficult and ended up being super delicious. It was about three hours of stirring, but I started with a gallon of whole milk, so you could probably make a smaller portion in less time. The recipe I used was:
>1 gallon whole milk
>2 lbs sugar (half white and half brown)
>.5 tsp baking soda
>.75 tsp salt
>vanilla extract (probably a couple teaspoons)

Bring to a boil, then lower heat to slightly above a simmer. Stir often with a wooden spoon for about three hours or until a pudding-like consistency is achieved. Then remove from heat, place into containers, and cool in fridge.
Also, you can just buy cans of dulce de leche.

Thanks for all the replies. I ended up making it 'au bain marie" in the oven.

I didn't feel safe about cooking it inside the can, it is very uncertain whether the can contains plastic or not.
