Company and product history

Impossible Foods was founded by
Patrick O. Brown, a biochemistry professor at Stanford, in 2011.
Impossible Foods initially also worked on plant-based products that emulated chicken, pork, fish, and dairy, but decided to concentrate first on creating a substitute for the
ground beef in burger patties.
In July 2016, the company launched its first
meat analogue product, the Impossible Burger, which is made from material derived from plants. The company says that making it uses 95% less land and 74% less water, and it emits about 87% less
greenhouse gas

began serving Impossible Foods' first plant-based sausage on pizzas in Florida, New Mexico, and Washington state. Patrick Brown said the product had involved the development of 50 prototype sausage products before Little Caesars began offering it to the public. In January 2020, Impossible Foods launched Impossible Sausage (also marketed as Impossible Pork) more widely.
In late 2021, the company launched Impossible Chicken.
Production and ingredients
Unlike most plant-based products intended to emulate meat, the Impossible Burger contains

US Food and Drug Administration (FDA). Impossible Foods filed updates with the FDA in 2017 and 2018. In July 2018, the FDA issued a "no questions" letter, accepting the unanimous conclusion of a panel of food-safety experts that the heme protein is safe to eat.
The FDA's acceptance in 2018 was limited to Impossible Burgers cooked in restaurants until soy leghemoglobin underwent safety review as a new food colorant for uncooked products. In July 2019, the FDA accepted the colorant in uncooked products, allowing the sale of Impossible Burgers in grocery stores in September the same year. In December 2019, the FDA affirmed this decision after considering an objection, finding that Impossible Foods had addressed the safety of soy leghemoglobin.
In May 2021, a San Francisco federal appeals court upheld the FDA's decision. The court held that the FDA had “substantial evidence” to deem heme in Impossible Burgers safe to eat.
