Embodiment 1

[0062] Embodiment 1 Research on the method of interaction between aroma substance 2-nonanone and (E, E)-2,4-hexadienal in roses

[0063] A method for studying the interaction of aroma substances in roses, comprising the steps of:

[0064] (1) Under different concentrations, the adopted sensory evaluation method is used to test the actual aroma intensity of 2-nonanone in the mixed solution, and the results are shown in Table 2; the mixed solution includes matrix solution and 2-nonanone, and the concentration is 2-nonanone The mass ratio C relative to the matrix solution A , mg / kg. Different groups of concentrations were recorded as C A1 , C A2 , C A3 , C A4 , C A5 . The matrix solution includes the following components in parts by weight: 30 parts of decane, 30 parts of undecane, 10 parts of dodecane, 15 parts of pentadecane and 15 parts of heptadecane.

[0065] Adopt the actual aroma intensity of the 2-nonanone of different group concentration in the sensory evaluation...

Embodiment 2

[0084] Embodiment 2 Research on the method of interaction between aroma substances geraniol and phenylethyl alcohol in roses

[0085] A method for studying the interaction of aroma substances in roses, comprising the steps of:

[0086] (1) Under different concentrations, the sensory evaluation method used to test the actual aroma intensity of geraniol in the mixed solution, the results are shown in Table 6; the mixed solution includes matrix solution and geraniol, and the concentration is the ratio of geraniol to matrix solution Mass ratio C A , mg / kg. Different groups of concentrations were recorded as C A1 , C A2 , C A3 , C A4 , C A5 . The matrix solution includes the following components in parts by weight: 30 parts of decane, 30 parts of undecane, 10 parts of dodecane, 15 parts of pentadecane and 15 parts of heptadecane.

[0087] Adopt the actual fragrance intensity of the geraniol of different group concentration in the sensory evaluation method test step 1 as men...

Embodiment 3

[0107] Example 3 A method for studying the interaction between aroma substances 2-nonanone and (E,E)-2,4-hexadienal in roses.

[0108] Compared with Example 1 of the present application, the only difference is that the number of concentration groups of 2-nonanone in step (1) is 6 groups, which are respectively C A1 , C A2 , C A3 , C A4 , C A5 and C A6 . Other conditions are the same as in Example 1, and the results are shown in Table 10.

[0109] Table 10

[0110]

[0111] Known from Example 1 that the n of (E,E)-2,4-hexadienal mB is 0.51, calculate the absolute value of the n difference between 2-nonanone and (E,E)-2,4-hexadienal|n mA- no mB |is 0.22. It can be seen that the interaction between 2-nonanone and (E,E)-2,4-hexadienal is a masking effect, and the result is the same as that in Example 1.

Abstract

The invention discloses a method for studying the interaction of aroma substances in roses. It comprises the following steps: (1) under different concentrations, test the actual aroma intensity of the aroma substance A in the mixed solution respectively; (2) use the Steven model function I=k×C n Calculate the theoretical aroma intensity of the aroma substance A at different concentrations; (3) calculate the sum of the squares of the difference between the actual aroma intensity and the theoretical aroma intensity of the aroma substance A at different concentrations; (4) use the programming solution method Calculate the k of aroma substance A in step 3 mA and n mA (5) the method of repeating steps 1-4 obtains the n of another aroma substance B mB ; (6) calculate n mA and n mB The absolute value of the difference|n mA ‑n mB |, to judge the interaction between two aroma substances. This method comprehensively and accurately studies the interaction between aroma substances, and can be widely used in the design of rose fragrance and essence systems.

Description

technical field [0001] The invention relates to a method for studying the interaction of aroma substances in roses. Background technique [0002] Roses are loved by people for their elegant and characteristic aroma, and the related flavor and fragrance products have been widely used in food, daily cosmetics, textile, leather, papermaking and other industries, and are closely related to the national economy and people's lives. At present, most of the rose essence products independently developed in China have insufficient characteristic fragrance coordination, realism and natural feeling, especially compared with the characteristic fragrance of natural products, which results in poor application effect in end products and cannot meet the requirements. Consumer demand has restricted the further development of the rose essence industry. [0003] The reason is that the interaction relationship between the characteristic aroma substances in natural roses is not clear, and the la...
