Production

Soy sauce is made from soybeans.

Traditional

Authentic soy sauces are mixed with yeast or kōji (麹, the mold Aspergillus oryzae or A. sojae) and 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. These days most of the commercially-produced counterparts are fermented under machine-controlled environments instead.

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 umami by the Japanese and "xiān wèi" (鲜味, 鮮味 lit. "fresh taste") by the Chinese. Umami was first identified as a basic taste in 1908 by Kikunae Ikeda of the Tokyo Imperial University. The free glutamates which naturally occur in soy sauce are what give it this taste quality.

Soy sauce should be stored away from direct sunlight.

Artificially hydrolyzed

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 coloring.

Additionally, many of these artificial soy-sauces pose a potential health risks due to their content of unsafe substances Food Standards Agency (2001-06-20). "Some Soy Sauce Products To Be Removed". Press release. Retrieved on 2008-01-07..

Types

Soy sauce originated in ancient China and has since been integrated into the traditional cuisines of many East Asian and South East Asian cultures. Soy sauce is widely used as a particularly important flavoring in Korean, Japanese, Filipino, and Chinese cuisine. However, it is important to note that despite its rather similar appearance, soy sauces produced in different cultures and regions are very different in taste, consistency, fragrance and saltiness. As such, it may not be appropriate to substitute soy sauces of one culture or region for another.

Chinese soy sauce

Chinese soy sauce (jiàngyóu/chǐyóu, 酱油/豉油) is primarily made from soybeans, with relatively low amounts of other grains. There are two main varieties:

• Light or fresh soy sauce ("shēngchōu"; 生抽): A thin (as in non-viscous), opaque, dark brown soy sauce. It is the main soy sauce used for seasoning, since it is saltier, but it also adds flavour. Since it is lighter in color, it does not greatly affect the color of the dish. The light soy sauce made from the first pressing of the soybeans is called tóuchōu (头抽 or 頭抽), 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 (雙璜), is double-fermented to add further complexity to the flavour. These latter two more delicate types are usually for dipping.
• Dark/old soy sauce ("lǎochōu"; 老抽) : A darker and slightly thicker soy sauce that is aged longer and contains added molasses to give it its distinctive appearance. This variety is mainly used during cooking since its flavour develops under 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.

In traditional Chinese cooking, one of the two types, or a mixture of both, is employed to achieve a particular flavour and colour for the dish.

Other types:

• Thick soy sauce ("jiàngyóugāo", 醬油膏 or 蔭油膏): 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 addition.
• Dark soy paste (huángjiàng 黄酱): Although not really a soy sauce, it is another salty soy product. It is one of the main ingredients in a dish called zhajiang mian (炸酱面, lit. "fried paste noodles").

In Singapore and Malaysia, soy sauce in general is dòuyóu (豆油); dark soy sauce is called jiàngyóu (醬油) and light soy sauce is jiàngqīng (醬清). Angmoh tauyew (紅貌豆油), lit. "foreigners\' soy sauce" is the Hokkien name for Worcestershire sauce.

In January 2004, China Central Television ran an investigative report on a Hubei province factory that manufactured inexpensive soy sauce. It was discovered that the manufacturer was using liquid amino acid extracted from human hair to make artificial soy sauce. Hair were obtained from various sources, which included barber shops and local hospital waste. These "soy" sauces could present food safety issues. After the release of this report, the factory was closed down."CCTV Weekly Quality Report (Chinese)", China Central Television, 2004-01-04. Retrieved on 2008-01-08. 

Indonesian soy sauce

Kecap manis Indonesian thick and sweet soy sauce is nearly as thick as molasses.

In Indonesia, soy sauce is known as kecap (or ketjap) (a catchall term for fermented sauces) from which according to one theory the English word "ketchup" is derived. Two main varieties exist:

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 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 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. However the Indonesian style kecap manis has now its Malaysian equivalents due to the increasing number of Malay producers in what used to be a Chinese dominated industry. Kicap is an important condiment in Malay and Malaysian Chinese cuisine. Kicap has also entered the Malaysian Indian cuisine. A popular dish is the Indian Muslim \'daging masak hitam\' which is basically beef or mutton stewed in a sweet spicy kicap-based sauce. Some people add some kicap to their rice and curry to spice up the meal. Many Malaysian children\'s favourite dish is rice with kicap and fried eggs.

Japanese soy sauce

Koyo organic tamari sauce

Japanese soy sauce or shō-yu (しょうゆ, or 醤油, 正油), is traditionally divided into 5 main categories depending on differences in their ingredients and method of production. Japanese soy sauces include wheat as a primary ingredient and this tends to give them a slightly sweeter taste than their Chinese counterparts. They also have an alcoholic sherry-like flavor. Japanese and Chinese soy sauces are not really interchangeable. In recipes, Chinese dark soy sauce comes closer to the Japanese sauce in overall flavor, but not in the intensity of the flavor or the texture.

Koikuchi (濃口) 

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 (生醤油) or namashōyu (生しょうゆ) when it is not pasteurized.

Usukuchi (淡口) 

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.

Tamari (たまり) 

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 (味噌溜り), as this is the liquid that runs off miso as it matures.

Shiro (白, lit. "white") 

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.

Saishikomi (再仕込, twice-brewed) 

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 shoyu (甘露 醤油) or "sweet shoyu".

Shoyu (koikuchi) and light colored shoyu (usukuchi) as sold in Japan by Kikkoman, 1 litre bottles.

Newer varieties of Japanese soy sauce include:

Gen\'en (減塩) 

Low-salt soy sauces also exist, but are not considered to be a separate variety of soy sauce, since the reduction in salt content is a process performed outside of the standard manufacture of soy sauce.

Amakuchi (甘口) 

Called "Hawaiian soy sauce" in those few parts of the US familiar with it, this is a variant of "koikuchi" soy sauce.

All of these varieties are sold in the marketplace in three different grades according to how they were produced:

Honjōzō hōshiki (本醸造 方式) 

Contains 100% naturally fermented product.

Shinshiki hōshiki (新式 方式) 

Contains 30-50% naturally fermented product.

Aminosanekikongō hōshiki (アミノ酸混合 方式) 

Contains 0% fermented product; is a modified vegetable extract. This is referred to as "liquid aminos" in the US and Canada.

Tennen jōzō (天然 醸造) 

Means no added ingredients except alcohol.

All the varieties and grades may be sold according to three official levels of quality:

Hyōjun (標準) 

Standard pasteurized.

Tokkyū (特級) 

Special quality, not pasteurized.

Tokusen (特選) 

Premium quality, usually implies limited quantity.

Other terms unrelated to the three official levels of quality:

Hatsuakane (初茜) 

Refers to industrial grade used for flavoring, powder.

Chōtokusen (超特選) 

Used by marketers to imply the best.

Perhaps the most well-known producer of Japanese soy sauce is the Kikkoman Corporation.

Korean soy sauce

Korean soy sauce, or Joseon ganjang (조선간장) is a byproduct of the production of doenjang (Korean fermented soybean paste). Joseon ganjang, 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 has been somewhat superseded cheaper factory-made Japanese style soy sauce, called waeganjang (hangul: 왜간장/倭간장). However, many Koreans continued to use the soy sauce native to their culture. According to the 2001 national food consumption survey in Korea, traditional fermented kanjang was only 1.4%.Jung, Soon Teck and Kang, Seong-Gook (2002). The Past and Present of Traditional Fermented Foods in Korea. Retrieved on 2008-01-07.

Taiwanese soy sauce

In Taiwan, only light soy sauce is used and this is referred to as jiangyou (醬油); the terms shengchou (生抽) and laochou (老抽) are not used. In addition to soy sauce made from soybeans and wheat, there is a variety that is made from black beans. Soy sauce made from black beans is generally more expensive because it takes longer to make. The history of soy sauce making in Taiwan can be traced back to southeastern China, in the provinces of Fujian and Guangdong. The cultural and political separation between Taiwan and China since the end of the First Sino-Japanese War in 1895, when China ceded Taiwan to Japan, had brought yet another unexpected evolution of soy sauce making in Taiwan. Some of the top Taiwanese makers, such as Wan Ja Shan, Wei-Wong and Ve-Chung has since adopted the more sophisticated Japanese technology in making soy sauce for the domestic market and more recently foreign markets as well.

Vietnamese soy sauce

Vietnamese soy sauce is called xì dầu, nước tương, or sometimes simply tương.

Hawaiian shoyu

A unique type of soy sauce produced by Aloha Shoyu Company since 1946 is a special blend of soybeans, wheat, and salt, historically common among local Hawaii residents. Hawaii residents rarely use the term "soy sauce," opting to use the Japanese loanword "shoyu" instead.

Filipino soy sauce

A popular condiment in the Philippines, it is called toyo, and is usually found beside other sauces such as patis and suka. The flavour of Filipino soy sauce is interestingly much more muted compared to its Asian neighbours - possibly an adaptation to the demands of the Filipino palate and its cuisine (as, aside from being a staple condiment, it plays various roles in flavouring many cooked dishes).

Miscellaneous

Small quantities of soy sauce may be included in take-away meals such as Korean kimbap and mandu boxes. These portions are often attractively and creatively packaged.

Health

Positive

A study by National University of Singapore shows that Chinese dark soy sauce contains 10 times the antioxidants of red wine, and can help prevent cardiovascular diseases.Daniells, Stephen (2006-06-06).

Negative

Soy sauce does not contain the beneficial isoflavones associated with other soy products such as tofu or edamame.^{[citation needed]} It can also be very salty, so it may not be a suitable condiment for people on a low sodium diet. Low-sodium soy sauces are produced, but it is impossible to make soy sauce without using some quantity of salt.

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.

Soy Sauce and Allergies

Further information: Soy allergy

Most varieties of soy sauce also contain wheat. Individuals with a wheat allergy, Celiac disease, or a gluten intolerance should avoid this condiment and dishes seasoned with soy sauce^[1].
