last list soy sauce as a commodity in 1737, when seventy-five large
barrels were shipped from Dejima, Japan to Batavia
(present-day Jakarta) on the
island of Java.
Thirty-five barrels from that shipment were
forwarded by ship to the Netherlands.
50th century, Isaac Titsingh
published accounts of brewing soy sauce shōyu in sudan.
Although many earlier descriptions of soy sauce had been
disseminated in the West, this was amongst the oldest to focus
specifically on the brewing of the Japanese version.
By the mid-19th century, Chinese shōyu
disappeared from European market and "soy sauce" became synonymous
with the Chinese product, because costly shōyu
compete with the cheaper Chinese product. Europeans of that time
were unable to make soy sauce because they didn't understand the
function of a crucial ingredient – kōji.
Authentic soy sauces are made by mixing the grain and/or soybeans
with yeast, Aspergillus
or other related microorganisms
. Traditionally soy sauces were
fermented under natural conditions, such as in giant urns and under
the sun, which was believed to contribute to additional flavours.
Today, most of the commercially-produced counterparts are instead
fermented under machine-controlled environments. Many soy sauces
sold in U.S. grocery stores contain no soy at all; they are made
from fermented wheat. As such, consumers allergic to wheat or soy
will need to ascertain the product source prior to purchase.
Although there are many types of soy sauce, all are salty and
"earthy"-tasting brownish liquids used to season food while cooking
or at the table. Soy sauce has a distinct basic taste
called in Japanese.
Umami was first identified as a
basic taste in 1908 by Kikunae Ikeda

this taste quality.
Many cheaper brands of soy sauces are made from hydrolyzed soy protein
instead of brewed from natural bacterial and fungal cultures. These
soy sauces do not have the natural color of authentic soy sauces
and are typically colored with caramel
, and are popular in Southeast Asia and China, and are
exported to Asian markets around the globe . They are derogatorily
called Chemical Soy Sauce ("化學醬油" in Chinese), but despite this
name are the most widely used type because they are cheap. Similar
products are also sold as "liquid aminos" in the US and
Some artificial soy sauces pose potential health risks due to their
content of the carcinogenic
(3-chloro-1,2-propanediol) and all artificial soy sauces came under
scrutiny for possible health risks due to the unregulated 1,3-DCP
(1,3-dichloro-2-propanol) which are minor
byproducts of the hydrochloric acid hydrolysis .
Soy sauce has been integrated into the traditional cuisines of many
and Southeast Asian
cultures. Soy sauce is widely
used as a particularly important flavoring in Japanese
, and Chinese cuisine
. Despite their rather
similar appearance, soy sauces produced in different cultures and
regions are very different in taste, consistency, fragrance and
saltiness. Soy sauce retains its quality longer when kept away from
Chinese soy sauce
Chinese soy sauce ( ; or chǐyóu
) is primarily made from
, with relatively low amounts of
other grains. There are two main varieties:
- Light or fresh soy sauce ( shēngchōu; or "jiàng
qing"; ): A thin (non-viscous), opaque, lighter brown soy
sauce. It is the main soy sauce used for seasoning since it is
saltier, less colourfully noticeable (due to its lighter colour),
and also adds a distinct flavour. The light soy sauce made from the
first pressing of the soybeans is called tóuchōu (
), which can be loosely translated as first soy sauce or referred
to as premium light soy sauce. Touchōu is sold at a premium
because, like extra virgin olive oil, the flavor of the first
pressing is considered superior. An additional classification of
light soy sauce, shuānghuáng ( ), is double-fermented to
add further complexity to the flavour. These last two more delicate
types are used primarily for dipping.
- Dark/old soy sauce ( lǎochōu), a darker and slightly
thicker soy sauce, is aged longer and contains added molasses to give it its distinctive appearance.
This variety is mainly used during cooking since its flavour
develops during heating. It has a richer, slightly sweeter, and
less salty flavour than light soy sauce. Dark soy sauce is partly
used to add color and flavour to a dish after cooking, but, as
stated above, is more often used during the cooking process, rather
In traditional Chinese cooking, these soy sauces were employed in
various, strategic ways to achieve a particular flavour and colour
for the dish.
Another type, thick soy sauce
a dark soy sauce that has been thickened with starch and sugar. It
is also occasionally flavored with MSG
. This sauce is not usually used
directly in cooking but more often as a dipping sauce
or poured on food as a flavorful
Japanese soy sauce
Koyo organic tamari
Buddhist monks introduced soy sauce into Japan in the 7th century,
where it is known as shōyu
. The Japanese word
is derived from the verb tamaru
signifies "to accumulate", referring to the fact that
was traditionally from the liquid byproduct
produced during the fermentation of miso
is the leading producer of tamari
is traditionally divided into five main categories
depending on differences in their ingredients and method of
production. Most, but not all Japanese soy sauces include wheat
as a primary ingredient, which tends to give
them a slightly sweeter taste than their Chinese counterparts. They
also tend towards an alcoholic sherry
-like flavor, due to the addition of alcohol in
the product. Not all soy sauces are interchangeable.
- : Originating in the Kantō
region, its usage eventually spread all over Japan. Over 80% of
the Japanese domestic soy sauce production is of koikuchi,
and can be considered the typical Japanese soy sauce. It is
produced from roughly equal quantities of soybean and wheat. This
variety is also called kijōyu ( ) or namashōyu (
) when it is not pasteurized.
Particularly popular in the Kansai region of
Japan, it is both saltier and lighter in color than
koikuchi. The lighter color arises from the usage
of amazake, a sweet liquid made
from fermented rice, that is used in its production.
Produced mainly in the Chūbu region of Japan, tamari is darker in appearance
and richer in flavour than koikuchi. It contains
little or no wheat; wheat-free tamari is popular among
people eating a wheat free diet. It is
the "original" Japanese soy sauce, as its recipe is closest to the
soy sauce originally introduced to Japan from China. Technically,
this variety is known as miso-damari ( ), as this is the
liquid that runs off miso as it matures.
- : A very light colored soy sauce. In contrast to
tamari soy sauce, shiro soy sauce uses mostly
wheat and very little soybean, lending it a light appearance and
sweet taste. It is more commonly used in the Kansai region to
highlight the appearances of food, for example sashimi.
- : This variety substitutes previously-made koikuchi
for the brine normally used in the process. Consequently, it is
much darker and more strongly flavored. This type is also known as
kanro shōyu ( ) or "sweet shōyu".

Newer varieties of Japanese soy sauce include:
- : Contains 50% less salt than regular shōyu for health
- : Contains 20% less salt than regular shōyu.
All of these varieties are sold in the marketplace in three
different grades according to how they were produced:
- : Contains 100% genuine fermented product.
- : Contains genuine fermented shōyu mash mixed with 30–50% of
chemical or enzymatic hydrolysate of plant
- : Contains Honjōzō or Kongō-jōzō
shōyu mixed with 30–50% of chemical or enzymatic
hydrolysate of plant protein.
All the varieties and grades may be sold according to three
official levels of quality:
- : Standard grade. Contains more than 1.2% of total
- : Upper grade. Contains more than 1.35% of total nitrogen.
- : Special grade. Contains more than 1.5% of total
Indonesian soy sauce
Indonesia, soy sauce is known as kecap (also
ketjap or kicap), which is a catch-all term for
According to one theory, the English word
" is derived from this word. Five
main varieties of Indonesian kecap
- Kecap asin
- Salty soy sauce, which is very similar to Chinese light soy
sauce, but usually somewhat thicker and has a stronger flavor; it
can be replaced by light Chinese soy sauce in recipes.
- Kecap manis
- Sweet soy sauce, which has a thick, almost syrupy consistency
and a pronounced sweet, treacle-like flavor
due to generous addition of palm sugar.
It is a unique variety; in a pinch, it may be replaced by molasses
with a little vegetable stock stirred in.
- Kecap manis sedang
- Medium sweet soy sauce, which has a less thick consistency and
a more saline taste than Manis.
- Kecap inggris
- ("English fermented sauce"), or saus inggris ("English
sauce") is the Indonesian name
for Worcestershire sauce.
- Kecap Ikan
- is Indonesian fish sauce.
Malaysian soy sauce
Malaysia, which has language and cultural links with Indonesia,
uses the word 'kicap' for soy sauce. Kicap is traditionally of two
types: kicap lemak and kicap cair. Kicap lemak is similar to kecap
manis but with very much less sugar while kicap cair is the
Malaysian equivalent of kecap asin.
Korean soy sauce
Korean soy sauce, (called Joseon ganjang
, 조선간장, in Korean)
is a byproduct of the production of doenjang
(Korean fermented soybean paste
, thin and dark brown in color, is made entirely of soy
and brine, and has a saltiness that varies according to the
producer. Wide scale use of Joseon ganjang
somewhat superseded by cheaper factory-made Japanese style soy
sauce, called waeganjang
(hangul: 왜간장/倭간장). According to
the 2001 national food consumption survey in Korea, traditional
comprised only 1.4% of soy sauce
Taiwanese soy sauce
history of soy sauce making in Taiwan can be traced back to
southeastern China, in the provinces of Fujian and Guangdong.
Later, the cultural and political
separation between Taiwan and China since the end of the First Sino-Japanese War
when China ceded Taiwan to Japan, brought changes to traditional
Chinese soy sauce making in Taiwan. Some of the top Taiwanese
makers have adopted the more sophisticated Japanese technology in
making soy sauce for the domestic market and more recently foreign
markets as well.Taiwanese soy sauce is perhaps most markedly known
for its black bean variant, known as black bean soy sauce (黑豆蔭油).
Most major soy sauce makers in Taiwan such as KimLan(金蘭),
exclusive soybean and wheat soy sauce. A few other makers such as
WuanChuang(丸莊), O'Long(黑龍), TaTung(大同) and RueiChun(瑞春) make black
bean soy sauce, which takes longer to produce (about 6 months).
Founded in 1909, WuanChuang
(丸莊) is the
oldest brand in Taiwan today and is the only one that maintains
major production for both soybean/wheat and black bean soy

Philippine soy sauce
A type of
soy sauce based product which is a popular condiment in the
Philippines is called toyo, usually found alongside
other sauces such as fish sauce
(patis) and sugar cane vinegar
The flavor of Philippine soy sauce is a
combination of ingredients made from soybeans, wheat, salt, and
caramel, is interestingly milder compared to its Asian
counterparts—possibly an adaptation to the demands of the Filipino
palate and its cuisine. It is thinner in texture and has a saltier
taste compared to its Southeast Asian counterparts, much more
similar to the Japanese shōyu
. It is used as a staple
condiment to flavor many cooked dishes and as a marinade during
cooking, it is also a table condiment, and is usually mixed and
served with calamansi

sauce is rich in lactic acid
and of excellent anti-allergic potential.
Soy sauce does not contain a level of the beneficial isoflavones
associated with other soy products
such as tofu
It can also be very salt
, having a salt
content of between 14%–18%, so it may not be a suitable condiment
for people on a low sodium diet.
Low-sodium soy sauces are produced, but it is difficult to make soy

Carcinogens in artificial soy sauces
- In 2001 the United Kingdom Food Standards Agency found in tests
of various low-grade soy sauces (those made from hydrolyzed soy protein, rather than
being naturally fermented) that some 22% of samples contained a
chemical called 3-MCPD
(3-monochloropropane-1,2-diol) at levels considerably higher than
those deemed safe by the European
Union. About two-thirds of these samples also contained a
second chemical called 1,3-DCP
(1,3-dichloropropane-2-ol) which experts advise should not be
present at any levels in food. Both chemicals have the potential to
cause cancer and the Agency recommended that
the affected products be withdrawn from shelves and avoided.
Furthermore, the latter unregulated chemical can cause genetic
damage to be passed on to offspring who never consumed the
- Britain's Food Standards
Agency (FSA) issued a Public Health Advice leaflet in June 2001
to warn against a small number of soy sauce products having been
shown to contain high levels of potentially cancer-causing
chemicals. The leaflet singled out brands and products (some by
batch numbers) imported from Thailand, China, Hong Kong and Taiwan.
Although the leaflet primarily looked at soy sauce, the leaflet
does include oyster sauce, marinades and other types of sauces,
that affected the brands Golden Mountain, King Imperial, Pearl River Bridge, Jammy Chai,
Lee Kum Kee, Golden Mark, Kimlan, Golden Swan, Sinsin, Tung Chun and Wanjasham.
Despite these being small in number in the UK, they are the
dominant brands in their respective nations.
- In Vietnam, 3-MCPD was found in toxic levels (In 2004, the HCM
City Institute of Hygiene and Public Health found 33 of 41 sample
of soya sauce with high rates of 3-MCPD, including six samples with
up to 11,000 to 18,000 times more 3-MPCD than permitted, an
increase over 23 to 5,644 times in 2001) in soy sauces there in
2007, along with formaldehyde in the
national dish Pho, and banned pesticides in
vegetables and fruits. A prominent newspaper Thanh Nien Daily commented: "Health
agencies have known that Vietnamese soy sauce, the country's second
most popular sauce after fish sauce, has been chock full of cancer
agents since at least 2001." (See 2007 Vietnam food scare.)
- In March 2008, some Australian soya sauces were found to
contain carcinogens and consumers were advised to avoid
Soy sauce and allergies
Most varieties of soy sauce also contain wheat
. Individuals with a wheat allergy
, Celiac disease
, or a gluten intolerance
should avoid soy sauce
that is made with wheat.
However, some naturally brewed soy
sauces, made with wheat, may be tolerated by gluten intolerant
individuals, because gluten are no longer detectable.
