Yes: potassium benzoate, calcium benzoate, sodium, potassium and calcium sorbates, sorbic and benzoic acids and many others (Food additives, E200-E290).
Nitrate is added to some products as preservative. Eating fresh food is an option to avoid prervatives. However unfresh food without any preservative is itself a health risk. Some say nitrates are a health risk in themselves, others disagree.
According to Wikipedia, in the process of food preservation, potassium nitrate is a common ingredient of salted meat, but there are theories indicating that using nitrates in meats can cause cancer. As a preservative it can be known as E252. I am unsure about potassium nitrate, but sodium nitrate has been marked as something we should avoid, but it actually has beneficial properties despite what some "studies" say, it in moderate does is nothing to fear, but instead may be beneficial. Potassium nitrate is still a mystery to me though, i plan to look into though eventually.
Toluene + HNO3/H2SO4 --> p-nitrotoluene (para directed nitration) p-nitrotoluene + Zn/HCl --> p-aminotoluene (changing NO2 to NH2 by reduction) p-aminotoluene +Br2 --> bromination ortho to NH2 Remove NH2 via diazonium salt and decomposition with 1) HONO (which is NaNO2+HCl), 2) H3PO2 for the final product.

Refer to the related link for an illustration of the formation of sodium chloride using Lewis dot structures.
Sodium Benzoate is used as a preservative for carbonated drinks. Coke stopped using it in their products in 2008. Some Pepsi products still contain Sodium Benzoate.
(additional)using Aliquat 336 in the synthesis of butyl benzoate from sodium benzoate and 1-bromobutane.
true
Using sodium chloride as condiment and preservative in reasonable amounts (2-5 g/day) doesn't cause an allergy; but the sensitivity of peoples to NaCl is different.
There can be no such reaction. Perhaps you meant HCl(aq) + C6H5COONa to get C6H5COOH plus NaCl. That would be converting the sodium salt of benzoic acid (sodium benzoate) into benzoic acid and sodium chloride by using hydrochloric acid.

This is only an opinion. The English grammar on many of these questions makes the reading and understanding confusing.
It is true; it is very frequently used for cabbage, cucumbers, hot peppers etc.

An alternative to using a fuse is to use an electrical circuit breaker.
The preservative may interfere with the tests that have been ordered on the urine sample. Also, no preservative of any kind should be added to urine for bacteriological cultures.
