Work

Access to nutritious food year round, especially in countries with cold winters, requires that the nutrients in food are preserved. Artturi Virtanen studied the chemistry of nutrients, including that in processes for dairy products. In 1932 he developed a method for better preserving the nutrients in hay. Using hydrochloric and sulfuric acids, he impeded certain processes, preservi.ng the grass' proteins and vitamins. This helped cows produce more nutritious milk year round without imported fodder
