Chocolate is not just a sweet glorious ray of edible
sunshine, Chocolate IS A PLANT!  It’s
been a 3,000 year journey from the biological roots of chocolate, to today’s
wild chocolate innovations….

Montezuma

When Montezuma met the Spanish conquistadores in 1519, he intended to overwhelm them with a lavish display of royal hospitality.  To impress, the emperor of six million people brought out fifty golden jugs of one of his most potent weapons – chocolate.  However, what he served to the awed Spanish was not at all like the sweet chocolate we enjoy today. The cacao plant (Theobroma Cacao) is native to the Amazon region, and Montezuma was serving up an elite tradition of chocolate that had begun 3,000 years before the Spanish arrival.  The Spanish experienced a drink made of the beans of the cacao pod, ground and mixed with water, vanilla, chile, and cornmeal, which had been poured back and forth at a height to create an enticing, bitter, melt-in-your-mouth froth.  In an instant, the global obsession with chocolate was born.

Cacao seedpods

Chocolate can now be found anywhere in the world, and it’s easy to forget that under the bright wrappers and diverse flavors, chocolate comes from a plant with a very powerful chemical profile.  The cacao tree and its precious seedpods only grow in equatorial regions of the world, and produce a bean that is much more than just tasty.  Cacao beans are psychoactive, with multiple compounds capable of stimulating the production of neurotransmitters in the brain.  Through their bitter and frothy beverage, Mesoamericans were the first to enjoy the stimulating effects of Theobromine, a chemical in cacao that is very similar to caffeine.  Theobromine increases blood flow, inducing a feeling of mental alertness, vigor, and overall well-being. On top of this dynamic duo, cacao also has Tryptophan and Phenylethylamine, among many other compoundsTryptophan assists in the creation of the “feel-good” neurotransmitter Serotonin.  Phenylethylamine assists with the creation of another happiness-inducing neurotransmitter, Dopamine.  These delightful neurotransmitters, plus a surprising number of antioxidants and anti-inflammatory compounds, can help explain humankind’s passionate three-thousand-year love affair with chocolate.

Cacao beans

The cacao beans that furnish this phytochemical feast are actually quite challenging to grow, and need just the right conditions and lots of care to fight the diseases and pests that typically attack them.  There are three main varieties of cacao bean available today, and within each variety there are several, often  genetically different, hybrid strains.  Relatively hardy Forestera beans make up 85 percent of the world’s chocolate.  Most prized, rare, and delicate are Criollo beans, which provide 3% of the world’s chocolate.  The hybrid of Forestera and Criollo is known as Trinitario, which was created in the 18th century when a hurricane nearly caused the Criollo variety to go extinct.  Although Criollo plants are not productive on a scale that can meet global demand, they produce flavors and aromas that are more complex and rich.  Much like wine, Criollo can be described as having notes of fruit, tobacco, or caramel.  Criollo was the preferred variety of the Aztec and Maya, and most likely the one that the Spanish enjoyed as part of Montezuma’s hospitality.

Truffles

Go to the supermarket today, and in the candy aisle you will see an array of chocolate worthy of an Aztec Emperor.  If you wish, you can pay a kingly fortune for the best of it  — the Guinness World Record holder is about 650 dollars for ONE 80-gram bar made of some of the rarest beans on earth! The West African nation of Cote d’Ivoire  produces 2/5ths of the worlds Forestera.  By contrast, most Criollo beans today come from small farms in Venezuela or Madagascar.  Since the very best beans are so rare and precious, the cost for the finest chocolate in the world can be incredibly high.  The world record holder, “La Chuorsa,” is put out by Swiss Chocolatier Attimo, using beans from a small 400 year old family farm in Venezuela.  To add to the flavor profile (and price) even further, it is enhanced with orange flavor and another expensive and rare ingredient, saffron.  If 650 dollars for one bar is a bit rich for your blood, there are other adventures in chocolate flavors out there.  For a mere 250 dollars you can purchase a chocolate truffle with a genuine fungus truffle inside!  Compartes Chocolates in California gets high ratings for creativity with less expensive bars of flavors like “Avocado & Chips,” “Fruity Pebbles,” and “Donuts and Coffee.”  An Aztec Emperor would surely recoil at the sweet, milky flavors of chocolate today, but that is the beauty in the biology of chocolate.  Cacao’s pleasing array of phytochemicals and rich flavors practically guarantee an enjoyable experience.  Whether taken bitter by an emperor or sweet by an excited trick-or-treater, on the molecular level, chocolate is sure to satisfy your brain and not just your sweet tooth.

The History Behind Valentine’s Day and Why We Celebrate it!



The History Behind Valentine’s Day!

The Roman’s had a festival called The Feast of Lupercalia that was celebrated in the middle of February.

An Emperor named Claudius II executed two men with the same name, Valentine, in different years, on the same day February 14th.

The first Valentine was a Roman Priest and was caught and thrown in prison for marrying. Later he was executed.

The second Valentine was a Temple Priest who helped Christians marry.

They were honored by the Catholic Church in which became Valentine’s Day on February 14th.

                                                                                                                           

 The Reason We Celebrate Valentine’s Day!

Since legend has it that both the Valentines were romantic, and both became Saints, St. Valentine’s Day became known to be

the romantic holiday for couples, a time to celebrate romance and love.

 

Even children love making Valentine’s Day cards.

In this video it shows children and parents how to make some neat Valentine’s Day cards of their own at home!

The Science of Chocolate

Happy #NationalChocolateDay!

With today being National Chocolate Day and only 3 days from Halloween, we figured it would be appropriate to discuss the science of chocolate! Many of you may have noticed different terms on your favorite candy bars wrapper describing it as chocolate, cocoa, & cacao.

So what are the differences to these types of chocolates? They are actually all products of the same cacao plant harvested in warm tropical climates around the Equator. Around 70% of cacao is harvested from western Africa. Cacao looks like a football shaped melon. Inside are the cacao beans, that harvesters extract and allow to dry in the sun. Once the beans have dried they are shipped all over the world. When they arrive at their location, the beans are cleaned, stripped of their shells and the raw cocoa nib is now ready to be processed. The nibs are melted together and then ground down to make a cocoa powder. The cocoa powder gets sugar, lecithin and other ingredients added to it, melted all together and formed into blocks or bars.

Again wishing you all a very happy #NationalChocolateDay!

FUN Science with Halloween Candy!

Check out our updated list of spooky science Halloween Activities here! 
Worried about having too much Halloween candy laying around? Here’s a little science you can do with your kids’ haul—or your own!

Chances are if you’ve got kids they’re going to want to go trick-or-treating. This means they’ll end up loaded with way more candy than you’d want them to actually eat. What could you do with the rest? Well, you could donate it, you could take it to a candy buyback program or you could do a little science with it! Here are a few ideas from Candyexperiments.com.

Lifesaver Lights
Here’s a simple one. Grab some wintergreen flavored Life Saver candies, stand in a dark room, face a mirror and chew them with your mouth open. You’ll see flashes of light that result from electrons in the candy; these are more easily visible thanks to the wintergreen flavoring.

 

 

Pop Rocks
Ever tried pouring some Pop Rocks into a glass of water? If you do, you’ll find that it’s a pretty effervescent experience.

 

 

 

Chocolate Bloom
By rapidly heating and cooling a piece of chocolate, you can gradually seperate it into its component parts. This results in white streaks and spirals called chocolate bloom. You can even still eat the chocolate once this is done—the texture might be a little unusual but it’s still perfectly edible!

 

Density Rainbow
Skittles are both delicious and colorful – here’s a way to really help that color shine. By using different quantities of various colored Skittles and the principle that sugar makes water more dense, you can create a liquid rainbow. This is one of the tougher experiments to try; make sure you pour the melted Skittles very slowly otherwise the different colors will just mix together.

 

Color Separation- Chromotography
Even if a piece of candy is only one color, that color can actually contain a variety of differently colored dyes. By dissolving candy coloring into water then slowly dripping that water down a piece of paper, it’s possible to see all those various colors. This is an easy experiment and the results are striking. Try it with brown M&Ms!
