Soya milk (simplified Chinese: 豆浆; traditional Chinese: 豆漿) also known as soy milk or soymilk, is a plant-based drink produced by soaking and grinding soybeans, boiling the mixture, and filtering out remaining particulates. It is a stable emulsion of oil, water, and protein. Its original form is an intermediate product of the manufacture of tofu. Originating in China, it became a common beverage in Europe and North America in the latter half of the 20th century, especially as production techniques were developed to give it a taste and consistency more closely resembling that of dairy milk. Soya milk may be used as a substitute for dairy milk by individuals who are vegan or are lactose intolerant.

Soya 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 [edit]

In China, the usual term 豆浆 dòujiāng (lit. "bean broth") is used for the traditional watery and beany beverage produced as an intermediate product in the production of tofu, whereas store-bought products designed to imitate the flavor and consistency of dairy milk, 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 [edit]

In the European Union, "milk" by law refers exclusively to "the normal mammary secretion obtained from one or more milkings without either addition thereto or extraction therefrom".^[6] Only cow's milk is allowed to be named "milk" on packaging, and any other milks must state the name of the respective animal: for example, "goat milk" or "sheep milk". The naming of soy drink as soy milk became subject of a 2017 court case before the Court of Justice of the European Union after a German consumer protection group filed an unfair competition complaint about a company describing its soya 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.^[7]

History [edit]

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 Mongol Yuan.^{[1] [2]} As doujiang, this drink remains a common watery form of soy milk in China, usually prepared from fresh soybeans. The compendium of Materia Medica, which was completed in 1578 ad, also has an evaluation of soymilk. Its use increased during the Qing dynasty, apparently due to the discovery that gently heating doujiang for at least 90 minutes hydrolyzed its raffinose and stachyose, oligosaccharides which can cause flatulence and digestive pain among lactose-intolerant adults.^{[8] [9]} By the 18th century, it was common enough that street vendors were hawking it;^[10] 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.^[11] 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.^[12] 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.^[13]

Consumption of soy milk had spread to England by the 14th century.^[14] Soymilk was mentioned in various European letters from China beginning in the 17th century.^[15] "Soy milk" entered the English language (as "soy-bean milk") in an 1897 USDA report.^{[16] [17]} Li Yuying established Caséo-Sojaïne, the first soy milk "dairy", in Colombes, France, in 1910; he received the first British and American patents for soy milk manufacturing in 1912 and 1913.^[12] J.A. Chard began production of "Soy Lac" in New York City, United States, in 1917.^[12] Harry W. Miller—an American businessman forced to relocate his factory from Shanghai owing to World War II—was similarly compelled by the USDA and the US dairy industry to use the term "Soya Lac" rather than "soy milk".^[12] John Harvey Kellogg had been working with what he called "soymilk" at his Battle Creek Sanitarium since 1930, but was similarly compelled to market his 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.^[12] Cornell researchers established the enzyme lipoxygenase as responsible for the "beany" flavor of soy milk made in 1966; the same research established a process for reducing or eliminating the bean flavor from commercial products.^{[19] [20]} With Tetra Pak cartons extending its 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 [edit]

Soy milk is made from whole soybeans or full-fat soy flour.^[22] The dry beans are soaked in water for a minimum of three hours up to overnight depending on the temperature of the water. The rehydrated beans then undergo wet grinding with enough added water to give the desired solids content to the final product which has a protein content of 1–4%, depending on the method of production.^[22] The ratio of water to beans on a weight basis is 10:1 for traditional soy milk.^[22] The resulting slurry or purée is brought to a boil to improve its taste properties, by heat inactivating soybean trypsin inhibitor, improve its flavor, and to sterilize the product.^{[22] [5]} Heating at or near the boiling point is continued for a period of time, 15–20 minutes, followed by the removal of insoluble residues (soy pulp fiber) by straining/filtration.^[22]

Processing requires the use of an anti-foaming agent or natural defoamer during the boiling step. Bringing filtered soy milk to a boil avoids the problem of foaming. It is generally opaque, white or off-white in color, and approximately the same consistency as cow's milk.^[22] Quality attributes during preparation include germination time for the beans used, acidity, total protein and carbohydrates, phytic acid content, and viscosity.^[22] Raw soy milk may be sweetened, flavored, and fortified with micronutrients.^[5] Once fully processed, soy milk products are typically sold in plastic bottles or plastic-coated cartons, such as tetrapaks.^[5]

Commerce [edit]

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.^{[23] [24]} Soy milk sales declined in the United States during 2018–19,^{[4] [24]} mainly due to the rising popularity of almond milk and loss of market share to the successful introduction of oat milk.^[25]

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.^[26] 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.^[26]

Usage [edit]

Nutrition [edit]

A cup (243 ml) serving of a generic unsweetened commercial nutrient-fortified brand of soy milk provides 80 calories from 4 g of carbohydrates (including 1 g of sugar), 4 g of fat and 7 g of protein.^[27] This processed soy milk contains appreciable levels of vitamin A, B vitamins, and vitamin D in a range of 10 to 45% of the Daily Value, with calcium and magnesium also in significant content.^[27]

It has a glycemic index of 34±4.^[28] For protein quality, one study gave soya milk a Digestible Indispensable Amino Acid Score (DIAAS) of 78% for infants, 99% for young children, and 117% for older children, adolescents, and adults, with the limiting amino acid for those groups being leucine, lysine, and valine respectively.^[29] A DIAAS of 100 or more is considered to be an excellent/high protein quality source.^[30]

Manufactured, sweetened soy milk has an oatmeal-like, nutty flavor.^[37] In acidic hot drinks, such as coffee, curdling may occur, requiring some manufacturers to add acidity regulators.^[38]

Phytic acid [edit]

Soybeans, and soy milk in particular, contain phytic acid, which may act as a chelating agent and inhibit mineral absorption, especially for diets already low in minerals.^{[39] [40]}

Regional [edit]

Soy milk soup with salt and vinegar, along with vegetables and wontons.

Soy milk is a common beverage in East Asian cuisines. In Chinese cuisine, "sweet" soy milk is made by adding cane sugar or simple syrup. "Salty" or "savory" soy milk is often combined with chopped pickled mustard greens, dried shrimp, youtiao croutons, chopped spring onions, cilantro, pork floss, and/or shallots, along with vinegar, sesame oil, soy sauce, and/or chili oil. Both are traditional breakfast foods, served hot or cold depending on the season or personal preference. At breakfast, it is often accompanied by starchy carbohydrate-rich foods like mantou (a thick, fluffy kind of roll or bun), youtiao (deep-fried dough sticks), and shaobing (sesame flatbread). Japanese cuisine uses soy milk to make yuba and as an occasional base for nabemono. In Korean cuisine, soy milk is used as the broth for making kongguksu, a cold noodle soup eaten mostly in summer. In many countries, soy milk is used in vegan and vegetarian food products and as a replacement for cow's milk in many recipes.^{[23] [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]

Ecological impact [edit]

Oat milk	0.19
Almond milk	0.16

Using soybeans to make milk instead of raising cows is ecologically advantageous.^[41] 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^[42] (specifically in the Amazon rainforest) and a range of other large-scale environmental harm.^[43] 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.^[42]
