Answer 1

Answer:

aromatic compound

Explanation:

others are aliphatic and open chain which do not have aroma

Answer 2

Answer:

aromatic compounds

Explanation:

Aroma compounds are usually extracted from vegetable matrices such as flowers, roots, fruits, and seeds to be used in perfumery, food, and the cosmetic industry. The main methods for aroma extraction are solvent extraction, maceration, CO2 supercritical extraction, and distillation. Distillation is largely applied for aroma compound extraction from plants, whereby the raw material is heated and the fragrance compounds are collected by vapor condensation. Steam distillation (hydrodistillation) is another technology in which water steam is responsible for opening the vegetable pores, removing the volatile aroma compounds. The condensed steam is a water solution rich in the desired aromatic compounds. The main disadvantage of distillation is the loss of heat-sensitive aroma compounds. For heat-sensitive compounds, such as some flowers' fragrance, expression (cold pressing) and enfleurage, a process whereby the aroma is adsorbed in a wax material and removed from the adsorbent with ethanol, are the most common methods.
