E621 is the sodium salt of glutamic acid, an amino acid that naturally occurs in various food items such as tomatoes, cheese, and mushrooms. It was first isolated in 1908 by Japanese chemist Kikunae Ikeda, who discovered that it imparted a unique savory flavor, known as umami. This finding spurred a culinary revolution, as the flavor was not adequately represented in the four basic taste sensations of sweet, sour, bitter, and salty.
2. Soil Health Improvement The application of ferrous sulphate can improve soil structure and fertility. It helps to increase the availability of other nutrients through a process known as chelation, where iron binds to other minerals, making them more accessible to plants. This can lead to a more balanced nutrient profile in the soil.
