Toast bread

Toast is a form of sliced bread that has been browned by exposure to radiant heat. This browning is the result of a Maillard reaction, which alters the flavor of the bread and makes it firmer so that it is easier to spread toppings on it. While the practice of toasting bread dates back to the Roman Empire, modern sliced toast bread is a staple in many cultures, produced by thousands of local and international bakeries.

The manufacturing of toast bread typically occurs in the country where it is sold due to the short shelf life of fresh bakery products. Large industrial bakeries use highly automated processes to ensure consistency in texture and size, specifically designed to fit into standardized household toasters. Major global food conglomerates often own regional bread brands, but the product remains a localized commodity in terms of supply chain and sourcing.
