María Orosa e Ylagan (November 29, 1892 – February 13, 1945) was a Filipina food technologist, pharmaceutical chemist, humanitarian, and war heroine. She experimented with foods native to the Philippines, and during World War II developed Soyalac (a nutrient rich drink from soybeans) and Darak (rice cookies packed with vitamin B-1, which prevents beriberi disease), which she also helped smuggle into Japanese-run internment camps that helped save the lives of thousands of Filipinos, Americans, and other nationals. She introduced to the public the well-known banana ketchup. Orosa completed her bachelor's and master's degrees in pharmaceutical chemistry, as well as an additional degree in food chemistry. She was then offered a position as an assistant chemist for the state of Washington before returning to the Philippines in 1922 to focus on addressing the problem of malnutrition in her homeland. She invented many types of food to minimize the need of imported products to feed Filipinos. She took advantage of the abundant natural resources of the Philippine islands such as native fruits, crops and vegetables to make the Philippines self-sufficient. During World War II, Orosa joined Marking's Guerrillas to fight for Philippines freedom. She invented over 700 recipes during her lifetime, including Soyalac and Darak, which saved thousands of lives during the war. She also invented a process for canning goods for the guerrilla warriors fighting for the liberation of the Philippines. Without her food inventions, thousands of people would have died in internment camps, hospitals, and on the streets. Early and family life Orosa was born on November 29, 1892 in Taal, Batangas, and was the fourth among the eight children of Simplicio A. Orosa and Juliana Ylagan-Orosa. Although her father died when she was still a child (and helped her mother in the family's general store), many of her siblings also became distinguished in the Philippines. Her elder brother, Engr. Vicente Ylagan Orosa Sr., became Secretary of Public Works and Communications, and, later, Chairman of the People's Homesite and Housing Corporation (PHHC) during the administration of President Ramon Magsaysay. Her brother, Dr. Sixto Ylagan Orosa Sr., became a pioneering doctor, and her nieces and nephews included banker Sixto L. Orosa, Jr., Philippine National Artist in Dance Leonor Orosa Goquiñgco, businessman José R. L. Orosa, award-winning cultural journalist Rosalinda L. Orosa, and her biographer Helen Orosa del Rosario. As a government-sponsored scholar, Orosa earned a bachelor's and master's degrees in pharmaceutical
