TOYKO, Nov. 30, 2020 /PRNewswire/
-- AISSY Inc., a company that provides data and consulting
related to the sensation of taste, has conducted an experiment at
the request of the Japan Food Product Overseas Promotion Center
(JFOODO)—an organization that promotes Japanese agricultural,
forestry, fishery produce and food products overseas—into the
increase in umami through the pairing of food with alcoholic
beverages.
Research is being conducted around the globe into the pairing of
alcoholic beverages with food in order to bring out additional
delicious flavors. For this experiment, AISSY has focused on the
metric of "umami," and has made use of the taste analyzer called
"Taste Sensor Leo," a machine co-developed by Keio University and AISSY that can convert taste
into numerical data. The experiment then proceeded to analyze the
increase in umami for the pairings of different food (a total of 25
dishes) and alcoholic beverages (a total of 7 types).
The results of the experiment indicate that sake, which contains
many elements of umami, increased the umami score no matter the
food it was combined with, and that the pairing of seafood like
grilled lobster, steamed mussels in white wine, and raw oysters
with sake achieved the highest increase in umami. This can be
predicted to be because the umami component inosinic acid found in
seafood and the umami component glutamic acid found in sake have a
reciprocal action, creating an "umami synergy effect" that further
increases umami.
Research Findings
*Numbers are rounded off to the third decimal place.
*Numbers are all umami values turned into points via the "Taste
Sensor Leo," and there may be individual variance in how delicious
different people find them.
●The increase in umami provided by sake is higher than
other alcoholic beverages
The addition of alcohol increased
the umami score for all of the food, but among them sake was the
one that increased the umami the most. The average increase across
all 25 food dishes for the other alcoholic beverages was 0.07 -
0.08 points, while for sake it reached 0.32 points.
●The combination of seafood and sake provided the
largest increase in umami score
When the scores for the increases in umami due to sake are looked
at for each dish, the results show that seafood such as grilled
lobster, softshell crab, and steamed mussels in white wine have the
largest increases in umami. This can be predicted to be because the
umami component inosinic acid found in seafood and the umami
component glutamic acid found in sake have a synergy effect, which
is then further enhanced by the suitable volume of fat found in the
seafood that makes it easier to increase umami.
●When making a selection based on umami, sake is the
best to pair with seafood
White wine is famous as a selection to pair with seafood, but when
measuring the increase in umami based in the metric of umami, the
pairing with sake exceeds that of white wine in umami score. For
example, results show that the classic pairing of raw oysters with
white wine (increase of 0.13 points) is actually superseded by a
pairing with sake (increase of 0.41 points).
[Comment from AISSY Representative Ryuichi Suzuki]
The human sense of taste developed in order to allow us to
determine whether something we put in our mouths is going to be
beneficial for us or not. Umami plays the role of signaling our
bodies that required proteins can be obtained from the food it
contains; glutamic acid, inosinic acid, guanylic acid, and succinic
acid - among others - have been confirmed as components of umami.
Each of these alone can function as umami, but it is also known
that having multiple umami components interact with each other can
create a synergistic effect and further enhance the resulting
umami. The excellent compatibility of Japanese sake and seafood has
long been talked about in Japan;
this experiment has provided a scientific basis for the reason why,
displaying how the sake—containing such umami components as
glutamic acid and succinic acid—synergizes well with the seafood,
which not only contains inosinic acid but also has fatty content
that allows for easier acquisition of the umami enhancing
effect.
[Comment from The Japan Food Product Overseas Promotion
Center (JFOODO) Director-General Hiroki
Oizumi]
JFOODO has settled upon the compatibility of seafood with sake as
our one approach for sharing the appeal of sake with overseas
markets. This experiment has proven that, in regard to an increase
in umami, sake is highly compatible with not only tradition
Japanese dishes but also a wide range of seafood. It proposes a new
method of selection, using the metric of "increase in umami" for
each pairing, and we hope for more people to come to enjoy the
harmony of seafood and sake.
Based on this experiment conducted by AISSY, JFOODO has released
some online content that proposes pairings of food and alcohol
based on this "increase in umami."

[Experimental Method]
Subjects for Measurement:
25 Dishes: Grilled lobster, soft-shell crab, steamed mussels in
white wine, grilled cod, grilled scallops with garlic, California roll, raw oysters, baked French
onion soup, calamari fritters, Prosciutto, omelet, sashimi (tuna),
grilled sausage, white fish carpaccio, Mushrooms ajillo, shrimp
cocktail, fried chicken, caprese, Camembert cheese, mashed potato,
clam chowder, steak, peperoni pizza, olives, caviar
Alcoholic Beverages: Japanese sake, white wine, red wine,
champagne, beer, gin, whisky
*For the Japanese sake, a total of four brands were used, with an
average value calculated from the score for each brand.
Measuring Method:
- The 25 dishes were prepared, dissolved in electrolyte solution
and analyzed using the taste analyzer "Taste Sensor Leo."*
- In order to analyze the taste of the pairing of the dishes and
alcohol, first the alcoholic beverage was applied to the measuring
device, and then without cleaning it the food dissolved in the
electrolyte solution was further applied, and then placed inside
the analysis apparatus.
- The increased score over the umami score of the food alone was
taken as the increase in umami due to the pairing.
[About AISSY]
AISSY works using the Taste Sensor Leo to perform a taste analysis
of food products, provide consulting based on the analytical data
received, and conduct joint research into taste. The Taste Sensor
Leo was developed by the Facility of Science and Technology at
Keio University, and uses AI technology
to recreate the human sensation of taste.
[About Taste Sensor Leo]
A machine co-developed by Keio
University and AISSY that artificially recreates the system
of human taste. Samples of food are placed not onto the taste buds
of the tongue but the sensors of the machine, which then measures
electrical signals from them and passes them through a proprietary
neural network (the realization of artificial intelligence) to
output quantitative numerical data based in the five basic
flavors.

consumer-focused organization created by the Japanese government
for the branding of Japanese agricultural, forestry, and fishery
produce and food products.
