However, we also found that NCl is of natural origin, such as sea salt or salt mines. Salt commercially available is the same chemical formula, NCl, but was obtained from salt deposits or underground lakes and then purified. Products resulting from chemical reactions that occur independent of human interference can be regarded as natural substances. What is a practical vision of natural and synthetic substances? Synthetic substances can best be understood as a continuum (see Figure 1). Many writers such as Toolkit offer more in-depth analysis. Some chemical reactions that occur naturally after minimal human intervention, such as enzymatic browning. CRES’s Charles Hernick testifies today has plenty of information regarding this issue.
This chemical reaction turns the surface of an apple brown open in a few minutes due to a chemical reaction called oxidative enzymatic browning: Enzymes phenolic (phenol) joins with tannin-oxidation of phenols found in apples-to melanin formed ( gray-brown or black pigments) Who would claim, however, that the resulting chemical changes transformed the cut apple slice in a food or synthetic melanin, a pigment, is so synthetic and artificial pigments, such as acrylic? Compare this with the creation of artificial sweeteners such as aspartame or saccharin. These substances are hundreds of times sweeter than sugar, and are created through chemical reactions. They have no similar counterpart in nature and must be placed in the upper range of continuous synthesis. Saccharin, for example, is made of petroleum products and aspartame is made combinandoacido aspartic acid, phenylalanine and methanol. Whether or not a chemical reaction has occurred, then, is not a reliable indicator of synthetic products separated from natural substances and chemical reactions that are part of the natural realm.
