Odoriferous Substances


organic compounds with characteristic pleasant odors used in the manufacture of various perfume and cosmetic goods, soaps, synthetic washing preparations, and food products. Odoriferous substances are abundant in nature. They form part of essential oils, aromatic resins, and other complex mixtures of organic substances extracted from animal and plant products.

Significant experimental data have been gathered about the connection between the odor of organic compounds and their structure; however, these data are not complete enough to reliably predict the odor of a newly synthesized substance on the basis of knowledge of all its structural features. Nevertheless, it is possible to establish some rules about the influence of an organic compound’s structural features on its odor. In particular, the size of the molecule and the degree of its branching greatly influence the odor. Compounds with a branched chain of carbon atoms in the molecule have stronger and often more pleasant odors than compounds with linear molecules. The odor is also influenced by the position of substitutes, the presence of multiple bonds, spatial factors, and molecular structure as a whole. Thus, of several valuable odoriferous substances used in industry, linalool (I) has the odor of lilies of the valley, citronellol (II) and beta-phenylethyl alcohol (III) have the odor of roses, citral (IV) has the odor of lemon, phenyl ether (V) that of geraniums, and diluted Ionone solutions, of violets.

The USSR produces thousands of tons of odoriferous substances yearly of more than 150 names. In industry odoriferous substances are synthesized from chemical raw materials and from products of the wood chemical industry (turpentines). Essential oils have also not lost their importance as sources of some odoriferous substances. It has become possible to synthesize many odoriferous substances that were formerly available only from natural raw materials as well as odoriferous substances not found in nature.

But for insects to thrive, the cattle must not be over-doped on antibiotics and odoriferous substances. Otherwise the insect will not survive in the excrement.
Volatile oils or essential oils are lipophilic, liquid, normally less dense than water and are highly odoriferous substances. The essential oil designation refers to its hydrophobic characteristics and to its similarity to oils in terms of viscosity.
Most studies implicate the coating on the posterior area of the tongue which is consistent with the presence of billions of bacteria, including anaerobes that live there and are capable of producing odoriferous substances. (17)
Bacteria from the saliva, (18) from plaque removed from gingivitis/periodontitis (16) as well as from the tongue (17) produce odoriferous substances in vitro.
Products exported most were wine (4.6 billion), wheat (3.4 bn), odoriferous substances (3.3 bn), food preparations (3.2 bn) and whiskies (2.7 bn).
The tests are only deemed to be successfully completed if the capsules are found to open and exude the odoriferous substances just before the component fails.
Smell sensors could also monitor plastic water and gas supply pipes to detect any cracks, because the odoriferous substances emitted are noticeable over long distances.
To prepare the ping-pong balls with the odors, one-quart Mason brand, food-storage jars were used to hold the balls and the odoriferous substances. Seven drops of an odoriferous substance were placed at the bottom of the jar and a wire screen was placed between the odoriferous substance and the ball to avoid direct contact of the liquid with the ping-pong balls.
The chemicals that serve as dinner bells for these freeloading flies are the same odoriferous substances that repel people and most insects, the researchers report in the Sept.
Thomas and Noble used 16 odoriferous substances compared to 8 for Langworthy and Jennings; Thomas and Noble administered 300 five-trial problems instead of Langworthy and Jenning's 30 problems each one administered to a criterion (16 of 20 successive trials correct) or a maximum number of trials (100); and Thomas and Noble baited all three food wells.
