Food doesn’t last. In days, sometimes hours, bread goes moldy, apple slices turn brown, and bacteria multiply in mayonnaise. But you can find all of these foods out on the shelf at the grocery store - hopefully unspoiled -- thanks to preservatives. But what exactly are preservatives? How do they help keep food edible? And are they safe? Eleanor Nelsen investigates.

I would like to note that BHT is not the same as vitimin E, rather it is a synthetic anolog of vitimin E. The species behaves as a synthetic analog of vitamin E, primarily acting as a terminating agent that suppresses autoxidation, a process whereby unsaturated (usually) organic compounds are attacked by atmospheric oxygen. BHT stops this autocatalytic reaction by converting peroxy radicals to hydroperoxides. It effects this function by donating a hydrogen atom: en.wikipedia.org/wiki/Butylated_hydroxytoluene

The intro to this video brought fear in me about mayonnaise having bacterial growth but on reading some research papers investigating the matter i am relieved to know that mayonnaise is not a bacterial culture medium & because of it's high acidity can actually never have an optimal environment for bacteria or fungi. Don't know why the video mentioned that at the start though? If anyone's gotta clue, enlighten me.
@magnumlugo1224

Mayonnaise, both commercially processed and home-made, has been associated with illnesses from Salmonella globally. The source of the Salmonella has been confirmed to be raw eggs.[64] Several outbreaks with fatal cases have been recorded, with a few major incidents. In a 1955 outbreak in Denmark, 10,000 people were affected by Salmonella from contaminated mayonnaise made by a large kitchen. The pH of the mayonnaise was found to be 5.1, with Salmonella counts of 180,000 CFU/g. The second outbreak, also in Denmark, caused 41 infections with two fatalities. The pH of the contaminated mayonnaise was 6.0, with Salmonella counts of 6 million CFU/g. In 1976 there were serious salmonellosis outbreaks on four flights to and from Spain which caused 500 cases and 6 fatalities. In the US, 404 people became ill and nine died in a New York City hospital due to hospital-prepared mayonnaise.[65] In all salmonellosis cases, the major reason was inadequate acidification of the mayonnaise, with a pH higher than the recommended upper limit of 4.1, with acetic acid as the main acidifying agent.[66] Some brands use pasteurized eggs which would reduce this risk factor

Mayo has long been thought in conventional wisdom to be something that goes bad quickly if left at room temperature, while the opposite is actually true. Poorly made mayo, as Magnum Lugo commented, was probably to blame, so perhaps this really was a much bigger problem 150 years ago when people used home-made mayo, but store-bought mayo will last safely quite some time.

Certain preservatives can lead to DNA damage (like the nitrates they spoke about) and cancer, our body has many processes to correct these damages. Each cell in our body has over 50,000 DNA damages every day, but most of us won't get cancer in our lifetimes, because we are evolved to correct these damages very well. We are not as good at fighting off bacterial infections that are very common from spoiled food. So while there is a small chance we will get DNA damage from certain preservatives, our body is much more capable of correcting that damage than it is of fighting off infection from bad food!

Most of us aren't trained to understand advanced nutrition. So what you think of preservatives would usually be based on whether you believe what you hear from others. I find very offensive the appeal to anti-expertise, like "Don't eat what you can't pronounce!" I do know something about some kinds of food contamination. I would be very much against eating bread with fungal molds, even if I had baked the bread myself. Some fungal toxins are very very bad. I think it's very unlikely that any preservative that had been approved as a food preservative could be as bad as the worst mold species. On the other hand, fresh foods that turn brown by oxidation are probably fine to eat. There's a difference between browning by oxidation, which has no bad health effects, and browning by bacterial decay, which might well make you sick. So it would be useful to know what the preservative is preserving. When I bake my own bread, I always freeze most of the loaf because otherwise I end up throwing away half the bread.

So we have to refrigerate mayo to slow down the multiplication of bacteria in it.

How about can foods that expire in 4 or 5 years time do those fall in the same category

I am surprised that there is no mention of canning en.wikipedia.org/wiki/Canning - This is a way to kill the microbes and keep oxidation away without using chemicals. Drying (some times with the combination of salt) is also commonly used. Cooling was also used long before refrigeration was invented, see ice cutting en.wikipedia.org/wiki/Ice_cutting . There is a good overview of food preservation here en.wikipedia.org/wiki/Food_preservation

I love food. Unspoiled food. So ... go preservatives! It's like the anti vacine crowd. If it does more good that harm it's good. Imagine starvation if we let food spoil

Also just like anti-vaccine claims of harm (and other food- and medical-linked pseudo-science, the claimed harms are also not found in the research. The only widely-used preservatives that have ever legitimately found to be harmful at any levels are sugars and salt. And it must be noted how those in appropriate amounts are not only safe, but absolutely vital. The closest anything else has been to get to the level of "maybe possibly having an effect on especially-sensitive people" are, as mentioned in the video, benzoates with ADHD.

smoking food - ancient method of preservation was banned by EU because some idiots said it's unhealthy.. we miss traditional smoked meat so much..

+Michał K Actually was that pretty smart as smoke contains a lot of carcinogenic substances (don't forget, smoking cigarettes is in principle nothing else, but inhaling smoke of burning leaves).

Yes, smoked food is carcinogenic. Higher smoked food consumption is correlated with higher rates of stomach cancer, I don't know why they didn't mention that in the video.

ppl ate it by thousands of years and we are still here, but suddenly now some sciencetists foud out how bad is it. I wonder who payed to them for research like this. Some big lobby related with production of shitty sausages using chemical "smoking" to remove competition with naturally smoked sausages?
@monkiram

Michał K Chemically smoked sausages tend to be similarly carcinogenic, I believe, from what I've read. I'm not sure why you're so skeptical. Lots of things we've done for centuries have been recently found to be harmful (for example, a lot of makeup used to contain lead, hats and thermometers used to be made with mercury, etc). I'm surprised it was banned though, there is so much that is carcinogenic that hasn't been banned, like the nitrite preservatives this video mentioned and cigarettes, the number one cause of preventable death in developed countries. It seems to me like they should label carcinogenic products so that people are aware but allow people to decide whether or not they want to use them.
