the answer is dilute sulphuric acid... thats what everyone says
You can use vinegar for preserving onions. and make sure when you use the clingfilm that the seal is airtight.
Salt was used a lot in early exploring- Meat would be covered in salt, and this would help preserve it.
Also pickling stuff works- like gherkins
Interestingly, sugar works as well- like with jam. That lasts for ages.
== == Acids used to preserve food include vinegars (white, red, balsamic, cider, sherry), lemon juice, lime juice, carbonic acid (carbonation), and citric acid. Alkali used to preserve food are less common, but include lye (used to preserve eggs, for example).
Pickling, fermentation and culturing do exactly that. Pickling can be done by natural fermentation or by adding vinegar. Increasing the acidity (aka lowering pH) of food below a pH of 4.6 makes the food inhospitable to pathogenic microorganisms.
yes,acids preserve foods as u cn take the example of lemon.citric acid is present in it. and it is used as a preservative in cooked vegetables.but it cant be used for those itemms which ae to be preserved 4 long time.

What kind of acids do you have in mind? You want to preserve food for how long? I think you could find some answer on Wikipedia.
The common acids used in food preservation are sorbic acid, benzoic acid and propionic acid. These acids impair the growth of bacteria on food.
the answer is 2 and 3 dilute sulpuric carries enough natural oils in which to be abbsobed
It depends on the strength of the two chemicals. Vinegar, lemon juice and full strength muriatic acid are all acids; baking soda solution, borax solution and lye solution are all alkalis. Muriatic acid and lye solution are both dangerous; the other four are safe--three of them are safe enough to drink.
Natural acids from foods are weak organic acids; of course exaggeration is not recommended for some illness.
is boric acid/borax is safe in keeping pulses safe from insects in rainy season Type your answer here...
No, sulphuric acid is a dangerous chemical.
the answer is dilute sulphuric acid... thats what everyone says
The acids found in foods, such as citric acid and lactic acid, are safe to eat because they are components of the foods, and the foods are safe to eat.

Pickling adjusts the PH level of the foods being canned to make them safe. Low PH level foods have vinegar added to them in specific amounts to raise the acid level.
It is contained in some foods.... But is it safe for human intake?
No coffee is one of the purine safe foods that Gout sufferers can imbibe in.
Never drink or even touch a strong acid or base.That said, people drink mild acids every day.Some acids you probably have drunk already, e. g. citric acid is in fruit juices and soft drinks. Acetic acid is the main component (5-10%) in vinegar.Stronger and more concentrated acid solutions, pH below 3, can be harmful or even toxic. A lot of acids are toxic anyhow!
Certain foods can aggravate your heartburn symptoms, and when planning your acid reflux diet, it's best to limit or avoid completely those foods and drinks that result in acid reflux. There are some foods that have little or no potential for causing heartburn.
Spicy foods usually cause most people to have acid reflux. Greasy and fatty foods also cause people to have acid reflux. Try eliminating those from your diet for a few days and see if that helps any.
Because they are not very strong, and your body can withstand a certain amount of acid. Your stomach doesn't care about acid in food because it's full of very strong acid called bile already.
People with acid reflux should avoid caffeine, greasy food, grains, sweets and acidic foods. Alcohol can also trigger heartburn, so it should be avoided. About.com has a heartburn section that includes charts listing foods to be avoided, foods to eat with discretion and foods that are safe.
Canning jars are an excellent way to preserve foods. It will keep the foods fresh and safe for at least 3 weeks in good conditions. In poor conditions, or if you fail to can it correctly, it won't last a day.
