caramelization mixture is called mirepoix. This technique is very important to the production of veggie burgers, as it adds both texture and flavor to the patty. The mirepoix mixture is then placed into another mixing tub, where dry ingredients such as oats, walnuts, potato flakes, and more are added. The mixture is then folded together to make a uniform mix. The moisture from the vegetables causes the mixture to become sticky, thus clumping together like cookie dough. This is important, as it allows the veggie burger to stick together to form the patty. The mixture is now put into an automatic patty-making machine or press. The press then punches out the patties into a disc shape onto a conveyor belt underneath. A constant spray of water may also be used to prevent any of the mixture from sticking to machinery parts. Once on the conveyor tray, the patties move along to be put onto baking trays. Patties are first inspected to make sure they are the correct shape, size, and texture to ensure a high-quality product. The trays are then put into a heated convection oven at a designated temperature and time. Once out of the oven, the patties are quickly frozen with techniques such as individual quick freezing and cryogenic freezing. These quick-freezing methods freeze the patties within 30 minutes to lock in nutrients and preserve texture by the formation of a number of small ice crystals. The frozen patties are again placed on a conveyor belt that takes them to a vacuum-packaging machine. The machine seals the patties into measured plastic sleeves and draws out any excess air. The packages are then loaded into printed cardboard boxes with the aid of another machine or done manually. The flaps on the box are then sealed closed and the product is kept in temperature-controlled storage before, during, and after delivery to grocery stores. Ingredients purpose Grains Grains are primarily used in the manufacturing of veggie burgers to act as a meat substitute. The grains, such as rice and wheat, provide carbohydrates and protein components and to provide bulk to the patty. They also provide texture to the burger, which can change depending on the type of grain used. This texture and look is important as they wish to make the patty look like a beef patty. Vegetables Vegetables such as corn, carrots, and mushrooms, provide the patty with texture and
