Flavours and fragrances in the daily chemical industry

Flavours and fragrances in the daily chemical industry only play a role in giving fragrance. As an ingredient in a product, the safety and stability of the formulation need to be taken into account. At the same time, as the average consumer, the fragrance of a product is an important criterion for them to judge the product, so the goodness of the flavouring added to the product plays a decisive role to some extent.

At the same time, as the average consumer, the fragrance of a product is an important criterion for them to judge the product, so the goodness of the flavouring added to the product plays a decisive role to some extent.

Below, I am posting an article on this subject from "The Art of Perfumery", written by the Wang family and some of the old-timers in the fragrance industry (e.g. Huang Zhixi). This article explains the longevity, stability and safety of fragrances and flavours from a flavouring perspective, and I hope it will help you in your future fragrance selection process.

Durability, stability and safety of fragrances and flavours

Spices, flavor quality, in addition to the performance of its fragrance rhyme and diffusion of energy, their aroma of lasting and stable degree, in the fragrance of the finished product whether it will cause discoloration, deterioration or affect the effect of its use and whether the human body is safe and harmless and other issues, are also extremely important factors. Therefore, flavouring workers in the prescription must be based on the fragrance of the finished product characteristics of the requirements, carefully select the appropriate spice varieties and appropriate dosage, and to be in line with all aspects of the application of the test, after the requirements, before the formula. Otherwise, some fragrances in the first with, aroma persistence decline, or fragrance time frame to shorten, or affect the colour of the finished product and the use of fragrance effect, or even lead to some human organs or skin hair damage, etc.. This is a problem that should be taken seriously by perfumers. In other words, that is, fragrance products, not due to the use of fragrance and not cause consequences.

     We know that the fragrance is composed of spices (and sometimes auxiliary raw materials or solvents). Generally speaking, if the choice of spices and the number of varieties are appropriate, basically can judge the quality of the flavor of the situation, but, fragrance in the preparation into, in the storage process or in the fragrance media (matrix), between the various spices, spices and media (matrix) between the components, often physical and chemical changes. Some of these changes can affect the persistence, stability and even safety of the flavouring and should not be ignored by the flavourist.

Persistence, stability and safety are three linked elements of a flavour that should be examined together, with persistence and stability in particular being more closely related.
