Condensed sweet and sour taste bursting from freshly peeled Iyokan

When the slightly thick outer skin of the Iyokan is peeled off, the scent bursts open, and the sweet and sour scent spreads as if you were bathed in fruit juice. Anyone who has eaten Iyokan, from children to the elderly, can tell “Ah! It’s Iyokan!” It has a unique sweet and sour flavor that distinguishes it from other citrus scents. The impression is that it is less bitter than Amanatsu and has a slightly sour taste.

Highly refreshing and ideal for a change of mood

The sweet and sourness of Iyokan essential oil is perfect for refreshing. Compared to overseas essential oils, it is sweeter than lemons, sweeter than grapefruits, and more sour than oranges. The essential oil of the fruit is said to have the power to revitalize people, and Iyokan essential oil is a scent that you want to smell when you are tired. Take a deep breath three times while smelling the scent directly from the bottle when you want to change your mood for a while between work, study, and housework. The familiar scent is perfect for children who have trouble concentrating.

Possibilities for utilization are expanding from the perspective of dementia prevention

The limbic system, which controls smell, and the hippocampus, which controls memory, are closely related. As a result, memories and scents are easily recorded in the brain, and the scent triggers a phenomenon in which memories are recalled. This is called the "Proust effect". This is because there is a scene in the novel, In Search of Lost Time, where the scent of madeleines and tea evokes memories of the past. In today's aging society, the number of dementia patients is also increasing. In order to prevent dementia, it turned out to be effective to train the sense of smell on a daily basis. When your brain recognizes the scent of when your mother peeled the Iyokan, it makes it easier to recall the memories of that time.

Citrus essential oil that can be used during the day because it is not phototoxic

Citrus essential oils from overseas manufacturers are generally extracted using the “pressing method” and contain aromatic ingredients that cause “phototoxicity”. "Phototoxicity" is an action that causes inflammation when exposed to sunlight while attached to the skin. For this reason, until now, citrus essential oils were always used at night or after aroma treatment without exposure to sunlight. However, most of the citrus essential oils of Japanese essential oils are collected by the "steam distillation method". As a result, it does not contain phototoxic ingredients and can be used 24 hours a day in aroma treatments and cosmetics. This was revolutionary, and it became possible to enjoy the scent of citrus in the refreshing hours of the morning.
