What You'll Learn
Soybeans are a staple crop in China
The soybean is a member of the Fabaceae family and is native to northeast China. It is one of the most common oilseed crops grown for food and forage in China, as well as other countries such as the United States, Europe, India, and South America. Soybeans have a lower level of carbohydrates compared to other legumes, but they make up for it with higher amounts of protein and oil. While soybeans are not typically consumed in large quantities by the general population, they are a staple for vegetarians and are present in the diet of almost everyone in China, even if only in the form of soy sauce.
Soybeans have played a significant role in China's agricultural trade strategy. The Chinese government has focused on importing certain "non-strategic" products, such as soy and meat, while imposing tariff rate quotas on cereals to maintain self-sufficiency in the grain sector. This strategy allows China to maintain its centuries-old political value of meeting the requirements in wheat and rice, which form the basis of the diet. Additionally, China has noted the dynamic development of soybean crops in countries like Brazil and Argentina, and has chosen to depend on these countries to support its domestic livestock industry by importing raw materials at competitive prices.
The Chinese government has also implemented policies to enhance the production of high-value-added goods derived from soybeans, such as soy oil and meal. In 1999, a 3% soybean single tariff policy was put into practice, replacing a higher tariff rate, to encourage the development of the crushing industry and capture crush margins. China has also invested in increasing soybean production, aiming to increase the soybean surface by 2.6 million hectares by 2020, with the additional production intended for human consumption rather than animal feed.

Soybeans are used to make bioplastics, not regular plastics
Soybeans are a common crop grown in several parts of the world, including China. They are used in food products such as tofu, which is made from dried soybeans that have been soaked in water, crushed, and boiled.
There have been claims on social media that soybean or soy-based products contain plastic. However, fact-checking websites have found these claims to be false. While soybeans do not contain plastic, they can be used to make bioplastics, which are different from regular plastics.
Bioplastics are made from natural resources such as vegetable oils and starches, and soybeans are one of the plants used in their production. A 2020 study showed that bioplastic can be synthesized from soybeans, which contain a lot of protein. Soybean by-products are also used to create biodegradable plant containers in the horticulture industry.
The process of making bioplastics involves the reaction of soy protein (degreasing soybean) with formaldehyde to form a three-dimensional network through methylene cross-linking. This bioplastic has high mechanical strength and is biodegradable. However, the major drawback of bioplastic is the high cost of production.
In summary, soybeans are used to make bioplastics, which are different from regular plastics. Bioplastics are biodegradable and made from natural resources, whereas regular plastics are made from petroleum products and are non-biodegradable.

Soybeans are not grown with chemicals in China
Soybeans are a crucial component of China's food security, being used in animal food, human food, and industrial products. While China is a major grower of soybeans, with an annual output of around 20 million tons, it is also the world's largest importer of soybeans, with over 88% of its soybean consumption relying on imports. This heavy reliance on imports is a result of decreasing domestic production and increasing demand, with the physical area dedicated to soybean production in China decreasing by 24% between 2008 and 2013.
Despite being a major grower and importer of soybeans, there is no evidence to suggest that soybeans in China contain plastic. In fact, fact-checking websites have debunked this claim, stating that naturally produced soy-based products do not contain plastic. However, it is important to note that soybeans, both domestically produced and imported, can be genetically modified (GM) to have stronger herbicide and insect resistance and produce higher yields. In December 2023, the Ministry of Agriculture and Rural Affairs (MARA) approved 14 GM soybean varieties, marking the first time the PRC government has approved the cultivation and commercialization of GM seeds.
While GM soybeans do not inherently contain plastic, there have been concerns about the safety of GM crops in China. Consumers have long been skeptical of GM foods due to concerns about their potential impact on health and the environment. Additionally, there have been food safety scandals, such as the contamination of baby formula with melamine (a chemical used to make plastic) in 2008, that have fueled distrust of GMOs and foreign control of China's GMO market.
It is important to differentiate between bioplastics and regular plastics when discussing the relationship between soybeans and plastic. Bioplastics are made from natural resources like vegetable oils and starches and are biodegradable. While soybeans are used to produce bioplastics, this does not mean that soybean-based foods, such as tofu, soy milk, and soy sauce, contain plastic. These foods are made through a process of soaking, crushing, boiling, and adding salt coagulants to separate the solid pulp from the soy milk, and do not involve the creation of plastic.

Soybeans are used in traditional Chinese cuisine
Soybeans are a species of legume native to East Asia, widely grown for their edible bean. They are a staple crop and the world's most grown legume, as well as an important source of food and
Soybeans are used in a variety of ways in traditional Chinese cuisine. They can be eaten whole, as in the case of edamame, or made into soy milk, from which tofu and tofu skin are made. Soy milk is called 'legume paste' or 'dou jiang' in Chinese. Tofu, or 'doufu', is made from dried soybeans that are soaked in water, crushed, and boiled. The mixture is then separated into solid pulp and soy milk. Salt coagulants are added to separate the curds from the whey. Tofu skin, or 'dou pi', is the dried skim from boiled soy milk. It is similar to dried tofu, but technically not the same, and is used in comparable ways.
Fermented soy foods include soy sauce, fermented bean paste, natto, and tempeh. Fermented black soybeans (douchi) and jiang (Chinese miso) are also used in Chinese cooking. Soybean sprouts, or 'huang', were first used as medicine, but became popular as a food during the Song dynasty (960-1279 CE). They are now used in stir-fried and braised dishes or eaten directly from their pods as a snack.
Soybeans are also pressed for their oil, which is widely used in cooking and industry.

Soybeans are used in Chinese industry
Soybeans are one of the most widely grown legumes, native to East Asia, and are a staple crop in China. They are a key source of food, used for their protein and oil content. Soybean oil is widely used in cooking, as well as in industry. Soybeans are also used in the production of many food and industrial products, such as tofu, oils, and animal feed. In addition, soybeans play a role in improving soil fertility by fixing nitrogen.
Soybeans have a long history in China, dating back to their domestication from the wild soybean (Glycine soja) in north-central China between 6,000 and 9,000 years ago. Initially, soybeans may have been more valuable as a fertiliser than as a food source, as they can enrich the soil for other crops. Over time, the nutritional value of soybeans was unlocked, and they became an important part of the Chinese diet.
Today, soybeans are the most imported agricultural product in China, with around 90% of its soybeans coming from international markets. This is due to limited arable land in China, which cannot meet the demand for soybeans. Imported soybeans are primarily used in oil and animal feed production.
While there have been claims that soybean or soy-based products contain plastic, these claims are false. However, it is true that soybeans can be used to make bioplastic, which is different from regular plastic as it is made from natural resources and is biodegradable. The use of soybeans in bioplastic production is expected to reduce the consumption of petroleum in plastic production.
