(1) Flavor evaluation 1
In the formulation shown in Table 1, purified water, sodium chloride (ordinary salt, Nippon Tobacco), and geniposide acid (Wako Pure Chemical Industries) were added to a glass sample bottle (50 mL). After covering this, the contents were dissolved to produce a container-packed liquid seasoning (test products 1 to 3). Sensory evaluation was performed about these flavors. The results are shown in Table 1.

  As shown in Table 1, the test product 1 had a peculiar taste and acidity peculiar to geniposide acid, and was not a preferable flavor. Test product 2 had a salty taste and a spicy flavor. On the other hand, the test products 3, 5 and 7 exhibited a mild salty taste, reduced the taste unique to geniposide acid, and had a better flavor than the test product 2. The flavor of test product 4 having a low geniposide acid content was not significantly different from that of test product 2. The flavor of the test product 6 having a low sodium content was milder in saltiness and slightly reduced in geniposide acid, but was not satisfactory. Thus, by containing a specific amount of sodium and geniposide acid, the salty taste was mellow, and the peculiar taste reduction peculiar to geniposide acid was shown.

(2) Flavor evaluation 2
In the formulation shown in Table 2, purified water, sodium chloride (ordinary salt, Nippon Tobacco), geniposide acid (Wako Pure Chemical Industries), and ethanol (Wako Pure Chemical Industries) were added to a glass sample bottle (50 mL volume). After covering this, the contents were dissolved to produce a container-packed liquid seasoning (test products 8 to 13). The test product 12 was immersed in a water bath at 85 ° C., subjected to heat treatment for 5 minutes, and then cooled with running water to make a test product 13. About these flavors, sensory evaluation was performed on the following evaluation criteria. The results are shown in Table 2.
Here, the test product 8 was used as a control product for evaluating the flavor of geniposide acid for each test product (evaluation d). The test product 9 was used as a control product for evaluating a mild salty taste for each test product (evaluation d).

[Evaluation criteria for mild saltiness]
a: Compared with the control product, the salty taste is very mellow.
b: The salty taste is mild compared to the control product.
c: The salty taste is slightly mellow compared to the control product.
d: Compared to the control product, the salty mellowness is equivalent.
e: The salty mellowness is lower than that of the control product.

[Evaluation criteria for flavor derived from geniposide acid]
a: The taste such as acidity and off-flavor derived from geniposide acid is not felt at all.
b: Flavors such as acidity and off-flavor derived from geniposide acid are considerably reduced compared to the control product.
c: Flavors such as acidity and off-flavor derived from geniposide acid are slightly reduced compared to the control product.
d: Flavors such as acidity and off-flavor derived from geniposide acid are equivalent to the control product.
e: Flavors such as acidity and off-flavor derived from geniposide acid are stronger than the control product.

As shown in Table 2, in the test products 10 and 11, the off-taste derived from geniposide acid was lowered and the salty taste was mellow. Furthermore, in the test product 12 in which ethanol was blended, the off-taste derived from geniposide acid was remarkably suppressed, but the salty taste was clear and the mellowness was slightly reduced. In the test product 9 in which this sample was heat-treated, the geniposide acid was not felt at all, and a very mild salty taste was exhibited.
Thus, it has been shown that the inclusion of sodium and geniposide acid makes the salty taste mild and the peculiar taste unique to geniposide acid decreases. Furthermore, it was shown that the taste of geniposide acid was improved by containing ethanol, and the flavor was further improved by heat treatment.

(3) Flavor evaluation 3
In the composition shown in Table 3, in a glass sample bottle (50 mL volume), purified water, salt (medium salt, Nippon Tobacco), geniposide acid (Wako Pure Chemical Industries), ethanol (Wako Pure Chemical Industries), potassium chloride (Wako Pure Chemical Industries) Industrial) was added. After covering this, the contents were dissolved to prepare a container-packed liquid seasoning (test products 14 to 19). The test product 18 was immersed in an 85 ° C. water bath, subjected to heat treatment for 5 minutes, and then cooled with running water to make a test product 19. Sensory evaluation was performed about these flavors. “Mellow salty taste” and “flavored from geniposide acid” were evaluated according to the same evaluation criteria as in (2). The “tasting taste derived from potassium” was evaluated according to the following evaluation criteria. The results are shown in Table 3.
Here, the test product 8 was used as a control product for evaluating the flavor of geniposide acid for each test product (evaluation d). The test product 9 was used as a control product for evaluating a mild salty taste for each test product (evaluation d). The test product 14 was used as a control product (evaluation d) when evaluating the flavor of potassium (K).

[Evaluation criteria for taste derived from potassium]
a: No nasty taste such as bitterness or pungent taste derived from potassium.
b: Unusual tastes such as potassium-derived bitterness and pungent taste are considerably reduced compared to the control product.
c: Disgusting tastes such as potassium-derived bitterness and pungent taste are slightly reduced compared to the control product.
d: Different tastes such as potassium-derived bitterness and pungent taste are equivalent to the control product.
e: Off-flavors such as potassium-derived bitterness and pungent taste are stronger than the control product.

As shown in Table 3, in the test products 15 and 17, it became clear that the taste derived from potassium is reduced by the addition of geniposide acid. Furthermore, in the test product 18 in which ethanol was blended, the geniposide acid-derived taste and potassium-derived taste were remarkably suppressed, but the salty taste was clear and the mellowness was slightly reduced. In the sample 19 in which this sample was heat-treated, the taste of potassium and the taste of geniposide acid were suppressed, and a mild salty taste was exhibited.
Thus, it was shown that not only the salty taste becomes mellow but also the taste of potassium is reduced by containing geniposide acid. Furthermore, it was shown that the taste of geniposide acid and the taste of potassium were improved by containing ethanol, and the flavor was further improved by heat treatment.
