example 1

[0032] An experiment was carried out to assess the perceived intensity of the main fragrance (Ginger Blossom) delivered continuously for 6 minutes supplemented by another fragrance (Pomme) delivered in pulses at 15 minute intervals. The experiment was performed at 28m 3 And the temperature and humidity are controlled in a small room (20°C and 55R / H).

[0033] A panel of 13 subjects was asked to rate their perceived fragrance intensity after 42 minutes of continuous main fragrance delivery. Assessments are made every minute according to a predetermined scale. The perceived fragrance of ginger flower was constant for the duration of the evaluation. Example 2

example 2

[0034] An experiment similar to that described in Example 1 was compared with a control experiment in which the main fragrance (ginger flower) was supplied to the chamber and another experiment in which the main The scent of the pomme is supplied continuously, while the pomme scent is pulsated. The pomme scent was supplied for 2 to 6 minutes at 15 minute intervals while the ginger flower scent was unchanged, which resulted in a higher sensory intensity than in the case of the unchanged ginger flower alone.

[0035] Experiments with 6 minute pulsations showed that the perceived fragrance diminished more slowly than 2 minute pulsations. Example 3

example 3

[0036] According to the general procedure of Example 1, an experiment was carried out to assess sensory intensity, in which a single spice (freesia and magnolia) was given in pulses for 2 minutes, between the end of one pulse and the beginning of the next pulse Hold for 2 minutes. The evaluation was carried out as described in Example 1 for a total of 46 minutes.

[0037] The pulsating supply maintained the perceived fragrance intensity at a constant level throughout the duration of the evaluation.
