Definitions
- the present invention relates to a method for evaluating an aroma component that can be added to a product such as food or cosmetics.
- the present invention also relates to a method for preparing a fragrance composition, which comprises evaluating an aroma component by the evaluation method and adjusting the blending ratio of the aroma component based on the evaluation method.
- a blended fragrance is a combination of aroma components selected from thousands of types of raw materials, and is produced as a scent reminiscent of various foods and plants. In addition, it is produced as a scent that takes into consideration the usage environment and consumer taste.
- Formulated fragrances developed for such various purposes are prepared by mixing various fragrance components in a container, but in the process of completing the blended fragrance, the scent of the blended fragrance itself is confirmed. The work of tasting a prototype close to the final product, or using a prototype cosmetic product in the actual usage environment to check the scent is repeated. There are several important points in this prototype.
- a diffusible aroma component useful for reproducing the expression of aroma in the oral cavity of a freshly cooked or freshly brewed hot food, and an aroma component that does not contribute to the development of such aroma are gas.
- An evaluation method for simple, objective and efficient sorting using chromatography is known (see Patent Document 1).
- this method is an evaluation method in which samples with different temperatures are prepared separately for the retronasal aroma when the sample is eaten, and the difference between the two is focused on. We do not pay attention to the aroma diffusivity of the aroma component and the change in the aroma concentration over time when the temperature changes.
- the perfume composition was added to an oral model environmental solution mixed with artificial saliva and a non-oral environmental solution that did not use artificial saliva, and the volatilized aroma components were collected and analyzed.
- a method for blending a fragrance that calculates a correction value and corrects the composition ratio of a fragrance composition is known (see Patent Document 2).
- this method is a method of calculating the correction value focusing on the presence or absence of artificial saliva, and pays attention to the aroma diffusivity and the change in aroma concentration over time when the state such as temperature or shape changes in one sample.
- an fragrance accord containing class 1, 2, and 3 fragrance components defined by an experimental speed in a predetermined ratio becomes a high-performance and high-influence bloom accord (see Patent Document 3).
- this method is an evaluation method that uses the experimental speed obtained by mixing cosmetics with water and measuring the time until the human sense of smell is detected at a distance from the water for classification, and one sample. Attention is paid to the aroma diffusivity when a state such as temperature or shape changes, but it is the aroma diffusivity with respect to a physical distance, and is not a method of showing a change in aroma concentration over time.
- Patent Document 5 a method of characterizing a fragrance component as a blooming fragrance component from the physical characteristics such as the boiling point of the fragrance component is known (see Patent Document 5).
- this method is a method to evaluate the aroma diffusivity based on the calculated numerical value, and it is suitable for the aroma diffusivity and the change in aroma concentration over time when the state such as temperature or shape changes in one sample. I'm not paying attention.
- the conventional method evaluates the characteristics of the aroma component based on the difference in conditions, or evaluates the characteristics of the aroma component by focusing on a specific physical property value, and the temperature or shape in one sample. It did not focus on the aroma diffusivity when such a state changes or the change in aroma concentration over time.
- the influence of the aroma component contained in the product on the aroma impression is more actual. It is desirable to evaluate in consideration of the consumption environment.
- the present inventor first describes the behavior of the aroma that spreads in the oral cavity, the posterior nostril, and the nasal cavity while eating the food, and the behavior of the aroma that spreads in the usage environment when the cosmetic is used. I thought that if we could grasp the behavior from the moment when the nasal cavity changes, we would be able to obtain information that is deeply related to the sensation that humans actually feel. For that purpose, it is necessary to build an environment modeled on the oral cavity for foods and a modeled environment for cosmetics. Further, the present inventor pays attention to the concentration change of each aroma component with respect to the diffusion behavior of the aroma, and the ratio of the detected amount immediately after the start of detection by the instrument analysis and the detected amount after an arbitrary time (that is, the aroma concentration increase).
- the rate we thought that it would be possible to evaluate the aroma diffusivity of the product in the consumption environment. It is possible to obtain the "diffusion rate per unit time" from the measurement time and the amount detected by the device measurement, but that would greatly depend on the measured value of the device measurement. Further, although the detected amount is small, the aroma diffusivity of the aroma component whose detected amount is greatly increased in an arbitrary time range is overlooked. Therefore, the present inventor has decided to adopt the detection amount ratio between the two points as an index in order to more appropriately evaluate the aroma diffusivity of each aroma component in the consumption environment of the product.
- the present inventor puts artificial saliva and a stirrer in a container warmed to about the human body temperature, puts chocolate for ice coating to which a fragrance component is added, and ice chocolate becomes artificial saliva.
- the amount of the aroma component detected in the headspace space where the aroma component was released while being mixed and dissolved was measured using a proton transfer reaction mass analyzer "PTR-TOFMS".
- PTR-TOFMS proton transfer reaction mass analyzer
- the present inventor puts tap water and a stirrer in a container at room temperature, puts dishwashing liquid containing a fragrance component into the container, and the dishwashing liquid mixes with tap water.
- the amount of the aroma component detected in the headspace space where the aroma component was released while foaming was measured using a proton transfer reaction mass analyzer "PTR-TOFMS".
- PTR-TOFMS proton transfer reaction mass analyzer
- the detection amount ratios obtained above indicate the aroma diffusivity of each aroma component in the model environment, and the expression of retronasal aroma from foods and cosmetics when formulating the desired perfume composition. It can be used as an index for controlling aroma diffusion.
- the present invention is a fragrance composition comprising the evaluation method of the aroma component shown below, the evaluation of the aroma component by the evaluation method, and the adjustment of the blending ratio of the aroma component contained in the product based on the evaluation.
- the present invention relates to a preparation method and a method of evaluating an aroma component by the above evaluation method and adjusting the perfume rate of the perfume composition to the product by adjusting the blending ratio of the aroma component contained in the product based on the evaluation.
