Soy milk, also known as soya milk or soymilk, is a plant-based drink produced by soaking and grinding

lactose intolerant
.

Soy milk is also used in making imitation dairy products such as soy yogurt, soy cream, soy kefir, and soy-based cheese analogues.[3][4] It is also used as an ingredient for making milkshakes, pancakes, smoothies, bread, mayonnaise, and baked goods.[5]

Names

In some parts of China, the term 豆浆

dòujiāng (lit. "bean broth") is used for the traditional watery beverage produced as an intermediate product in the production of tofu, while store-bought products designed to imitate the flavor and consistency of dairy milk (and may contain a mixture of dairy and soy), are more often known as 豆奶 dòunǎi ("bean milk").[citation needed
]

In other countries, there are sometimes legal impediments to the equivalents of the name "soy milk". In such jurisdictions, the manufacturers of plant milks typically label their products the equivalent of "soy beverage" or "soy drink".[citation needed]

Naming in the EU

In the

unfair competition complaint about a company describing its soy and tofu products as 'milk' or 'cheese'. The Court of Justice ruled that such designations cannot be legally used for purely plant-based products and that additions indicating the plant origin of the products (soy milk) does not influence that prohibition.[8]

History

The earliest record of soybean milk is on a stone slab of the

Eastern Han dynasty
unearthed in China, on which is engraved the situation of making soy milk in ancient kitchens.

A tofu broth (doufujiang) c. 1365 was used during the

street vendors were hawking it;[11] in the 19th, it was also common to take a cup to tofu shops to get hot, fresh doujiang for breakfast. It was already often paired with youtiao, which was dipped into it.[12] The process was industrialized in early Republican China. By 1929, two Shanghai factories were selling over 1000 bottles a day and another in Beijing was almost as productive itself.[13] Following disruption from the Second World War and the Chinese Civil War, soy milk began to be marketed in soft drink-like fashion in Hong Kong, Singapore, and Japan in the 1950s.[14]

Soymilk was mentioned in various European letters from China beginning in the 17th century.

acidophilus-enriched beverage as "Soygal" when it began commercial production in 1942.[18]

A string of 40 court cases against Rich Products between 1949 and 1974 finally established that non-dairy "milks" and imitation dairy products were "a new and distinct food", rather than inferior and illegal knock-offs.

shelf-life, Hong Kong-based Vitasoy reintroduced soy milk to the US market in 1980 and brought it to 20 other countries within a few years.[19] Alpro similarly began production in Belgium in 1980, quickly becoming Europe's leading producer.[19] New production technology and techniques began to permit soy beverages with an appreciably more milk-like flavor and consistency in the mid-1980s.[21]

Preparation

Soy milk is made from whole soybeans or full-fat soy flour.

soy pulp fiber) by straining/filtration.[22]

Processing requires the use of an

Soy odor

Traditional East Asian soymilk has a "beany" odor, partly of

lipooxygenase (LOX) in the soy oxidizing the fat in the beans. Rehydrating the beans allows the reaction to proceed with the oxygen gas dissolved in soaking water.[23] To eliminate the odor, one can either disable the LOX enzyme with heat or remove the oxygen dissolved in the water. The former can be achieved by soaking beans in hot water (a "hot grind"), skipping the soak entirely, or blanching the soy in water or steam first.[24] The latter can be achieved by a variety of chemical means, such as adding glucose and glucose oxidase to consume the oxygen.[25] The soybean cultivar also influences the odor[26] and a mutant cultivar lacking LOX completely has been produced.[27]

The issue and preference of soy odor also affects products made from soymilk, especially tofu. See Tofu § Flavor.

Commerce

With soybean production increasing worldwide during the early 21st century,[3] and consumer interest in plant milks growing from demand in Asia, Europe, and the United States,[3][4][5] soy milk became the second-most consumed plant milk (after almond milk) by 2019.[28][29] Soy milk sales declined in the United States during 2018–19,[4][29] mainly due to the rising popularity of almond milk and loss of market share to the successful introduction of oat milk.[30]

According to market research in 2019, the worldwide market for soy milk was growing at an annual rate of 6%, and was forecast to reach $11 billion in total commerce by 2025.[31] Growth in consumption was due mainly to expanding the flavors of sweetened soy milks and uses in desserts, whereas unsweetened soy milk was being used particularly in Asia-Pacific countries as an ingredient in snacks and various prepared foods.[31]

Phytic acid

Soybeans, and soy milk in particular, contain phytic acid[citation needed], which may act as a chelating agent and inhibit mineral absorption, especially for diets already low in minerals.[43][44] However, dietary intake of phytic acid may help reduce the risk of developing colon cancer.[45][46]

In many countries, soy milk is used in vegan and vegetarian food products and as a substituve replacement for cow's milk in many recipes.[28][3] Soy milk is also used in making imitation dairy products such as soy yogurt, soy cream, soy kefir and soy-based cheese analogues.[3][4] It is also used as an ingredient for making milkshakes, pancakes, smoothies, bread, mayonnaise, and baked goods.[5]

Using soybeans to make milk instead of raising cows is ecologically advantageous.[47][48] Cows require much more energy to produce milk, since the farmer must feed the animal, which can consume up to 24 kilograms (53 lb) of food in dry matter basis and 90 to 180 litres (24 to 48 US gal) of water a day, producing an average of 40 kilograms (88 lb) of milk a day. Legumes, including the soybean plant, also replenish the nitrogen content of the soil in which they are grown.

The cultivation of soybeans in South America is a cause of deforestation[49] (specifically in the Amazon rainforest) and a range of other large-scale environmental harm.[50] However, the majority of soybean cultivation worldwide, especially in South America where cattle farming is widespread, is intended for livestock fodder rather than soy milk production.[49]
