Info

Narcissus in perfumery 395 collection is carried out in an area 200 km across and 500 km from Grasse. It is therefore practically impossible for a flower destined to be treated at Grasse to arrive in a satisfactory state of freshness. Picking, collection and transport by truck takes two to three days, and the flowers are largely degraded during this length of time. For this reason, a central extraction plant has been set up right in the heart of the collection area, allowing the treatment of flowers on the same day that they are collected. Thanks to this proximity, the quality of a product has been transformed and greatly improved. The central facility alone processes 50–60% of the total flowers collected each year. QUANTITIES The gathering of narcissus flowers is, as is the case for most plant material, subject to the weather. This situation is perhaps accentuated by the fact that flowering takes place in mountainous regions, at altitudes between 600 and 1500 metres. Thus, cold weather persisting in the preceding months, or late frosts, can jeopardise flowering. Collection may equally be spoilt in years with strong rain, because of the excessive, rapid growth of grass, practically covering the narcissus flowers and making cropping impossible in some places. However, it is true that, even if the flowers are poor, in theory there will be more than enough to satisfy the needs of the perfume industry. The problem is simply that the pickers, after having evaluated the density of flowering and having carried out a rapid calculation of profitability by the hour, decide to crop . . . or not to crop. Their decision will depend on whether collection levels that year will be normal or low. The quantities gathered will also be adjusted according to the needs indicated by the industry. This is why, with medium sized crop being between 300 and 400 tonnes, quantities can vary between 200 and 600 tonnes in different years. These are the weights of flowers alone, excluding the stems and leaves. EXTRACTION Narcissus flowers are fragile and delicate. It is desirable to treat them as soon as possible after collection, in order to preserve their olfactory qualities. While waiting for treatment, the flowers are spread out on a cement slab at the factory (Figure 17.3). They are stored for as little time as possible, in a thin layer which is turned over constantly to avoid fermentation starting. As is the case for the flowers of rose, jasmin, orange blossom and many others, they are treated by extraction with solvents (hexane being the usual solvent), in order to obtain a viscous product called a ‘concrete’ (Figure 17.4). The concrete contains a high proportion of vegetable waxes that render it useless, in that state, in perfumes. It is, therefore, necessary to remove these waxes in order to render the product soluble in alcohol. The concrete is a thick substance that hardens on cooling, and it has to be heated in a bain-marie to soften before being processed. The concrete is subjected to a second transformation through washing with alcohol in order to separate the waxes and to obtain the final product, referred to as an ‘absolute’. It is the absolute that is used in the manufacture of perfumes. The narcissus belongs to the category of noble
