Dole is no longer using BPA in any of its packaging products.
I would say it's probably more of an esthetic thing. Black olives wouldn't look appetizing in a jar with all the black liquid in it.Many green olives are either naturally fermented or acidified and do not require a metal can. Most black olives are a low-acid food and require a higher heat canning process - which is more easily accomplished in a metal can.
no but they do eat cat food (that is true!)
Green olives are a little unripe, but still ready to eat. Black olives are the same olives, but much riper. Green olives turn black as they mature.
BPA, also known as Bisphenol-A, is a chemical commonly found in shatterproof plastics and food and beverage cans. BPA has been receiving attention lately because research is linking it to breast and prostate cancer, obesity, learning disabilities and heart disease. It is commonly found in baby bottles, plastic sports bottles and food and beverage cans. You can find out more about BPA at the Mount Sinai Children's Environmental Health Center's website at www.greeningourchildren.org.

It takes 15 black olives and 18 slices of pepperoni to make a large pizza. Olives cost $1.20 per can of 24 black olives.

Yes
You can add black olives to your salad if you'd like, but a common green salad does not usually have them.
Black olives are actually green olives that are ripe. There are many types of olives and many of them are already dark in color. But the basic green olive (neé spanish olive or manzinilla olive) ripen over time into black olives ;)
Because the part where oil comes from so they make olive oil in bottles. Olive oil comes in glass botles, plastic bottles and metal cans. It all depends on the quality and the way the seller of the oil want to present the product. Olive oil in glass bottles is usually more expensive.
More than likely, it is to help stabilize their color. UV exposure might turn them grey. Besides, they are unattractive to look at, especially since an iron solution is added to help stabilize the color. It is similar to why cherries are packed in cans of colored syrup.Answer:The process for making black olives results in the olives being packaged in a non sterile solution that may allow them to become contaminated with botulism. To prevent this from happening (it's bad for business to have your customers die), the olives are cooked in sealed containers. Glass jars cannot withstand the internal pressures generated by the cooking process and the olives must be cooked in metal cans.
