With individuals linked to memory and bond formation through our sense of smell, no wonder the fragrance is a kind of emotional driven industry is often romantic. But behind the history, feelings and stories told of the smell of modern perfume, is born in the test tube of the modern laboratory gloss.
After all, perfume is a science that involves creativity, chemistry, and a keen sense of smell. Over the past few decades, there has been a number of scientific improvements that have improved the extraction process and improved the quality of the ingredients used in the spice industry, while using less invasive methods. High quality ingredients that need to be noticed are the pure smell, more powerful and realistic, resulting in the improvement of the standard of the perfume industry. The most notable innovations to capture aromatic compounds include head space technology and supercritical carbon dioxide extraction.
Developed in 1980s, head space technology is a ground breaking technology used to capture a variety of objects or environments in which volatile odor compounds exist in the surrounding air. This elusive scent may be a unique scent of a church or an aroma of a precious rose garden. Measurement of the desired odor, including ensuring that the glass dome around the object of interest, create a sealed sealed, so that the inert gas can form a vacuum trap odor compounds through space.
The compounds were then collected through various means of solvent traps or absorption materials. Then the molecules of the perfume and the reconstructed samples were then analyzed to create a new fragrance note. This approach allows for a more pure, natural fragrance of flowers / plants to produce what is needed, life is like a particular environment or the smell of the evening experience of tropical rain forest. In addition to the re creation of a specific aromatic atmosphere, headspace techniques for the wide range of applications in plant life, to capture the scent of rare flowers without essential oils can be due to the generation of endangered species. Other applications in the perfume include frozen fresh fruits such as exotic mango, litchi and ginger in the application of headspace technology in the fruit is melting - to provide the smell, there is sweet and juicy, just bite the fresh.
Innovation in the aroma is the supercritical CO2 extraction to increase the flavor. The supercritical CO2 extraction technology comes from the extraction process used in caffeinating products containing caffeine, such as coffee beans and tea. The method is now being applied to capture a variety of natural aromatic compounds in a non intrusive, low-temperature and low toxicity method, in which the other applications, such as expression, distillation and conventional solvent extraction failure. The method includes changing the temperature and pressure conditions of the carbon dioxide (usually gas), and its super critical point - in which it becomes a supercritical fluid, using the properties of the gas and the liquid. Supercritical carbon dioxide fluid through natural substances, to extract a variety of aromatic compounds. Then the pressure is reduced, and the carbon dioxide is returned to the gas, which evaporates, leaving the extraction of aromatic compounds. This approach is due to its low environmental impact and the ability to utilize aromatic compounds without using too much heat or stirring to make it perfect for fragrance extraction even for the most delicate natural materials.
