Ammonia fertilizer is a widely used source of nitrogen, a key nutrient required for plant growth. Nitrogen is essential for the formation of amino acids, proteins, and chlorophyll. Ammonia fertilizers, such as anhydrous ammonia, are directly injected into the soil, where they quickly convert to ammonium ions that plants can absorb. This form of fertilizer is highly efficient, providing a rapid supply of nitrogen to crops. However, careful handling and application are necessary due to ammonia's potential volatility and risk of environmental impact.

In the realm of fruit preservation, sodium metabisulfite acts effectively to inhibit the growth of bacteria, yeast, and molds that can cause spoilage. For instance, dried fruits like apricots and raisins are often treated with sodium metabisulfite to maintain their color and prevent unwanted fermentation. Without this treatment, dried fruits may become discolored and lose their appeal, ultimately leading to a decrease in marketability. The antioxidant properties of SMBS also help to prevent enzymatic browning, which is especially important in fresh-cut fruits and vegetables. By minimizing discoloration, sodium metabisulfite helps maintain the visual and taste qualities of these products.

The Impact of Artificial Additives in Our Food

1. Wet Processing This method involves reacting phosphate rock with sulfuric acid to produce phosphoric acid and gypsum as a byproduct. It is the most common method for producing phosphoric acid due to its cost-effectiveness and efficiency. The resulting phosphoric acid can be used directly in fertilizers or further refined for food-grade applications.

Sodium metabisulfite, often abbreviated as SMB, is an essential chemical compound widely used in various industries. As a sodium salt of metabisulfurous acid, it appears as a white crystalline powder with a pungent sulfur odor. In China, the production and consumption of sodium metabisulfite have seen significant growth due to its versatility and the burgeoning chemical market.
