Soy in the context of "Staple crop"

Agriculture began independently in different parts of the globe, and included a diverse range of taxa. At least eleven separate regions of the Old and New World were involved as independent centers of origin.The development of agriculture about 12,000 years ago changed the way humans lived. They switched from nomadic hunter-gatherer lifestyles to permanent settlements and farming.

Wild grains were collected and eaten from at least 104,000 years ago. However, domestication did not occur until much later. The earliest evidence of small-scale cultivation of edible grasses is from around 21,000 BC with the Ohalo II people on the shores of the Sea of Galilee. By around 9500 BC, the eight Neolithic founder crops – emmer wheat, einkorn wheat, hulled barley, peas, lentils, bitter vetch, chickpeas, and flax – were cultivated in the Levant. Rye may have been cultivated earlier, but this claim remains controversial. Regardless, rye's spread from Southwest Asia to the Atlantic was independent of the Neolithic founder crop package. Rice was domesticated in China by 6200 BC with earliest known cultivation from 5700 BC, followed by mung, soy and azuki beans. Rice was also independently domesticated in West Africa and cultivated by 1000 BC. Pigs were domesticated in Mesopotamia around 11,000 years ago, followed by sheep. Cattle were domesticated from the wild aurochs in the areas of modern Turkey and India around 8500 BC. Camels were domesticated late, perhaps around 3000 BC.

Phosphatidylcholines (PC) are a class of phospholipids that incorporate choline as a headgroup.They are a major component of biological membranes and can easily be obtained from a variety of readily available sources, such as egg yolk or soybeans, from which they are mechanically or chemically extracted using hexane. They are also a member of the lecithin group of yellow-brownish fatty substances occurring in animal and plant tissues. Dipalmitoylphosphatidylcholine (lecithin) is a major component of the pulmonary surfactant, and is often used in the lecithin–sphingomyelin ratio to calculate fetal lung maturity. While phosphatidylcholines are found in all plant and animal cells, they are absent in the membranes of most bacteria, including Escherichia coli. Purified phosphatidylcholine is produced commercially.

The name lecithin was derived from Greek λέκιθος, lekithos 'egg yolk' by Theodore Nicolas Gobley, a French chemist and pharmacist of the mid-19th century, who applied it to the egg yolk phosphatidylcholine that he identified in 1847. Gobley eventually completely described his lecithin from chemical structural point of view, in 1874. Phosphatidylcholines are such a major component of lecithin that in some contexts the terms are sometimes used as synonyms. However, lecithin extracts consist of a mixture of phosphatidylcholine and other compounds. It is also used along with sodium taurocholate for simulating fed- and fasted-state biorelevant media in dissolution studies of highly lipophilic drugs.

Pará (Brazilian Portuguese: [paˈɾa] ) is a state of Brazil, located in northern Brazil and traversed by the lower Amazon River. It borders the Brazilian states of Amapá, Maranhão, Tocantins, Mato Grosso, Amazonas and Roraima. To the northwest are the borders of Guyana and Suriname, to the northeast of Pará is the Atlantic Ocean. The capital and largest city is Belém, which is located at the Marajó bay, near the estuary of the Amazon river. The state, which is home to 4.1% of the Brazilian population, is responsible for just 2.2% of the Brazilian GDP.

Pará is the most populous state of the North Region, with a population of over 8.6 million, being the ninth-most populous state in Brazil. It is the second-largest state of Brazil in area, at 1.2 million square kilometres (460,000 sq mi), second only to Amazonas upriver. Its most famous icons are the Amazon River and the Amazon rainforest. Pará produces rubber (extracted from rubber tree groves), cassava, açaí, pineapple, cocoa, black pepper, coconut, banana, tropical hardwoods such as mahogany, and minerals such as iron ore and bauxite. A new commodity crop is soy, cultivated in the region of Santarém.

Food speculation refers to the buying and selling of futures contracts or other commodity derivatives by traders with the aim of profiting from changes in food prices. Food speculation can be both positive and negative for food producers and buyers. It is betting on food prices in financial markets.

Food speculation by global players like banks, hedge funds or pension funds is alleged to cause price swings in staple foods such as wheat, maize and soy – even though too large price swings in an idealized economy are theoretically ruled out: Adam Smith in 1776 reasoned that the only way to make money from commodities trading is by buying low and selling high, which has the effect of smoothing out price swings and mitigating shortages. For the actors, the apparently random swings are predictable, which means potential huge profits. For the global poor, food speculation and resulting price peaks may result in increased poverty or even famine.

A meat alternative or meat substitute, also referred to as a plant-based meat, mock meat, or alternative protein, is a food product that is made from vegetarian or vegan ingredients and is consumed as a replacement for meat. The objective of meat alternatives is to replicate the qualities of meat, including its mouthfeel, flavor, and appearance. Plant- and fungus-based substitutes are frequently made with soy (e.g., tofu, tempeh, and textured vegetable protein), but may also be made from wheat gluten as in seitan, pea protein as in the Beyond Burger, or mycoprotein as in Quorn. Alternative protein foods can also be made by precision fermentation, where single cell organisms such as yeast produce specific proteins using a carbon source; or can be grown by culturing animal cells outside an animal, based on tissue engineering techniques. The ingredients of meat alternatives include 50–80% water, 10–25% textured vegetable proteins, 4–20% non-textured proteins, 0–15% fat and oil, 3-10% flavors/spices, 1–5% binding agents, and 0–0.5% coloring agents.  

Meatless tissue engineering involves the cultivation of stem cells on natural or synthetic scaffolds to create meat-like products. Scaffolds can be made from various materials, including plant-derived biomaterials, synthetic polymers, animal-based proteins, and self-assembling polypeptides. It is these 3D scaffold-based methods that provide a specialized structural environment for cellular growth. Alternatively, scaffold-free methods promote cell aggregation, allowing cells to self-organize into tissue-like structures.
