Sugar

The human tongue can essentially detect five different flavors: sweet, sour, salty, bitter, and savory (also: umami). What substances taste sweet? Sugar, of course – but why do we have a natural attraction to sugar and sweets? When we are born, we have a natural attraction to sugars, because sugars (usually) mean energy. On the same token, at a young age, many children dislike vegetable. When cooked (and exponentially worse when over-cooked) enzymes react in response to the high heat to form extremely bitter compounds. And in many cases in the natural world, poisons and toxics are bitter. As humans mature, our food pallet becomes more sophisticated and becomes more comfortable with pungent, spicy, sour, and bitter flavors. It is for this reason why adults are more comfortable consuming vegetables; their pallets are less affected to the bitter components of a dish more than the other complex harmony of aromatics and spices of a fully-‘developed’ pallet.

Studies have shown that there is a relation between the ability (and severity) of tasting PTC (phenylthiocarbamide) paper and the flavor of vegetables. PTC is a chemical which is extremely bitter to some of the population, while virtually tasteless to others. This strange difference of two extremes is dependent on a genetic encoding to taste certain bitter compounds. Those with high sensitivity to PTC (myself included) showed an extreme disgust to vegetables (I can recall placing the PTC paper on my tongue and immediately spitting it out. That taste lingered for hours – if it helps, the paper tasted like chloroquine or quinacrine that you would take for prevention against malaria.). Conversely, those who seemed to have no effect from the PTC had no issues with vegetable consumption. Therefore, some children don’t eat their vegetables because they don’t want to, but because s/he is too sensitive to the bitter compounds or even become unpalatable…so it is not entirely the kids fault.

Moving onto another subject of sugars… (I understand the majority of the text above is about bitters, but I thought it was interesting and decided to do the extra research)

Albeit not as complex as salts and flour, sugar has a unique array of varieties. Apart from the normal white granulated sugar, there is brown sugar (golden brown and dark brown), raw sugar, and all types of sugar syrups (like corn syrup). So how does sugar arrive on our supermarket shelves?

It all begins with the sugarcane stock.
Sugarcanes are any of about twenty five species of tall grasses (like bamboo) in the Saccharum genus which originated somewhere in Asia. In many cases, the sugar found in the sugarcanes at the grocery store is a hybrid of the twenty five. Cultivators carefully select the best characteristics of the sugarcane and decide which best moves to the next generation of crop. It is not uncommon for stocks to grow from six feet to as high as nineteen feet in height.

After harvest, the cultivators have several options to produce a consumer product, all based on its final destination. In Costa Rica, I have had the pleasure of taking the whole sugarcane, pressing it through rollers, and straining the pulp to produce a pitcher of a sugarcane juice. This elixir was served in a shot glass and looked like a clouded mixed drink. The taste was concentrated – sweet, but not overwhelming and with a nutty flavor. It was an opportunity to enjoy a rich Costa Rican delicacy of cold pressed sugarcane.
