The Economic Botany of Manilkara zapota (L.) Van Royen

Manilkara zapota (L.) Van Royen American economics is familiar with using by - product Manilkara zapota (L.) Van Royen, but few people know the history of products. Chewing gum was born from the economics of a chic tree (M. zapota). Everywhere in Mexico and Central America, the plant Sapotaceae family is known for its latex. Manilkara zapota (Synonym: Achras zapota L.) is an evergreen canopy tree of medium size (height 15-30 m) native to Central America and is now grown in tropical regions of the world (Castner, Timme, & Duke, 1998) . .

Regarding the above, in Mexico you can add that Aztecs and Maya also found the juice of Manilkara zapota, a tree commonly known as Tikozaporte. Bouncing off when thrown on hard ground. These Mexican indigenous people used sap to make the balls and they used these balls to play games with hands and feet. Strictly speaking, they invented chewing gum. Only Flair people may have found a more sticky version that can be used to bubble.

Van Royen is convinced that the committee's laboratory can choose to synthesize gemstones. To test him, I asked him to see a half-carat pale yellow Gemesis diamond. Van Royen is a man who grew a happy laughing happy beard, photographed rock music through a ten times jeweler's magnifying glass, and walk with it. "This is beautiful," he said with a smile. Although the laboratory of Van Royen is equipped with DiamondSure and DiamondView (Diamond High Commission works closely with the Gemstone Defense Program), he records jewels on a more elaborate device - a Fourier transform infrared spectrometer Write - will spread out the crystal. A large printout is hung on the machine to display 6 sets of graphics. Van Royen pointed out that there is a unique spike on the right end of the horizontal axis. "If it is synthetic, it should look like this," he said. Sure enough, the graphic displayed by the machine is as indicated by Van Royen.

Wrong, Jeff Van Roy, senior scientist of the Diamond High Council of Belgium Diamond Industry said. In an interview at the Council headquarters of Hoveniersstraat in Antwerp, "If people truly love each other, they will give each other a true stone." "If it was created last week, it is not a symbol of eternal love." The same applies to products that De Beers supports. Van Royen said he forgot to compare cultured pearls. Synthetic diamonds are like synthetic emeralds introduced in large quantities in the mid 1970's. At first it was very expensive, but at the Jewelry Institute we found it easy to distinguish the composition using a standard microscope. Price fell, now it is less than 3% of nature
