Flavors and fragrances have been composing the integral components of a broad range of consumer goods and even some kinds of pharmaceutical products. The wide application of these aroma chemicals significantly enhances the pressure of supplying to meet the increasing needs. With the development of modern chemical industry, many spices, those are only extracted from certain animals or plants before, can be prepared by chemical synthetic methods. Synthetic perfume has gradually replaced the dominant position of natural spices because of its many advantages such as pure fragrance, low price and mass production.
Total synthesis is a method of synthesizing perfume by a series of organic synthesis reactions which are based on a variety of basic chemical products. Petroleum chemical and coal chemical products are the most commonly used raw materials during such procedure. Taking the synthesis of karanal as an example, it was prepared by 2-methyl diethyl malonate, 2-bromobuta-ne and privet aldehyde through alkylation、restore and aldol condensation reactions.
Semisynthesis, also known as partial chemical synthesis, represents a chemical synthetic approach to produce desirable substances with compounds isolated from natural sources acting as the starting materials. Compared with the total synthesis, chemical compounds produced by semisynthetic method generally have a higher molecular weight and more complex molecular structure.
In the fermentation engineering, biosynthesis or biotransformation can be used to prepare natural flavors and fragrances; the use of enzyme engineering can produce a lot of flavor and perfume precursors. Genetic engineering can transfer and express one gene of certain microorganisms, such as escherichia coli, bacillus, yeasts, and thus increase the yield of a specific enzyme and increase the yield of the target.

What are aroma compounds in flavors and fragrances?
Aroma compounds, also known as odorants or flavor molecules, are chemical substances that provide characteristic scents or tastes. They can be naturally derived or synthetically produced, and are essential in creating distinct profiles in food, beverages, cosmetics, and perfumes.
How are flavor and fragrance compounds synthesized?
Flavor and fragrance synthesis involves designing and producing aroma molecules through organic synthesis, biocatalysis, or extraction techniques. This process allows precise control over molecular structure and purity, enabling the creation of natural-identical, synthetic, or novel aroma compounds.
What types of aroma compounds are used in perfumes and food products?
Common classes include esters, aldehydes, ketones, lactones, terpenes, and phenolic compounds. Each class contributes unique sensory properties, from fruity and floral notes to woody, spicy, or creamy profiles.
How are aroma compounds classified in food flavor applications?
Food flavors can be classified as natural, nature-identical, or artificial based on their origin and production method. They may also be categorized by sensory profile, such as fruity, citrus, herbal, savory, or sweet.
What flavor and fragrance synthesis capabilities does BOC Sciences offer?
BOC Sciences provides custom synthesis of aroma compounds, including rare and complex molecules, isotopically labeled variants, and key fragrance intermediates. Our expertise covers diverse chemical classes to support product development, sensory research, and formulation studies.
We create flavors and fragrances with targeted sensory profiles, meeting research and product development needs.
