Gathered here you will find lots of asparagus facts. One that causes a lot of interest is where does that asparagus urine smell come from?
We will look at what family the Asparagus Plant comes from and where the major growers are around the world.
Then there are all those different ways you come across asparagus - canned asparagus, frozen asparagus, wild asparagus, white asparagus.
So here goes:
Studies have shown that not everyone produces urine with that distinctive asparagus urine odor and that not all those that do produce urine with this smell can smell it. However somewhere between a few and 2/3rds of the population produce "asparagus pee" so don't worry, you are not alone whichever group you fall into.
The smell comes from the metabolism of a sulphorous compound found in asparagus called Mercaptan. This same compound is found in rotten eggs, onions, garlic and skunks scent!
There is no agreement on the actual compound causing the smell but various studies indicate that both the production of the smell and the ability to smell it are linked to an individuals genes. Quite a lot of studies have been done but more work is needed to fully understand what is going on.
Along with something that retains some mystery are some facts that are not known to be true: It is not a known "asparagus fact" that producing the asparagus urine is a sign of intelligence! nor should you worry that eating asparagus is bad for you just because it makes your pee smell funny!
Asparagus comes from the Lily family (liliceae) along with the onion, garlic and tulip.
According the the Encyclopedia Brittanica online there are around 300 species of the asparagus family around the world including more than one poisonous species resident of Africa which are prized as ornamental plants with red berries.
The best known of the family is the garden asparagus whose latin name is asparagus officianlis

Another "Asparagus Fact" : Purple asparagus is a variety (or more accurately a number of varieties) of asparagus. It tends to be sweeter than the green spears due to a slightly higher sugar content. As a result it is often good eaten raw in salads etc.
The higher sugar content is not sufficient to leave you reaching for your calculator to count the calories. Purple asparagus is still a good healthy low calorie vegetable.
Both White and Green asparagus can be purchased canned although the "can" is sometimes a glass jar! White asparagus is sold in this form widely on the continent and especially in Germany. It is less common in the UK. You might find them hidden away on the top shelf in the supermarket or in a local delicatessen or online. Buying online with delivery charges will however work out to be quite expensive.
You will find varying views on the taste / texture of canned asparagus...! Be your own judge and try using it in recipes rather than just straight out of the tin.
Your best bet might be to buy excess asparagus during the fresh asparagus season and can them yourself.
Asparagus is sold in many processed forms including packet and tinned asparagus soups. Follow this Asparagus Soup Taste Test link to see what we think of some of these products.
