One of the primary functions of sodium benzoate is its ability to inhibit the growth of bacteria, yeast, and fungi. This antimicrobial property is particularly effective in acidic conditions, where it acts to disrupt the cell membranes of these microorganisms, leading to their death or growth inhibition. Thus, sodium benzoate is commonly added to products with a low pH, such as carbonated beverages, fruit juices, pickles, and salad dressings. By preventing spoilage, sodium benzoate helps to extend the shelf life of these products without the need for refrigeration, making it a practical solution for food manufacturers.
Applying nitrogen fertilizers requires careful consideration to maximize their effectiveness while minimizing environmental harm. Common application methods include broadcasting, banding, and fertigation. Broadcasting involves spreading fertilizers evenly over the soil surface, while banding places fertilizers in concentrated bands near plant roots. Fertigation, which involves incorporating fertilizers into irrigation systems, allows for precise control over nutrient delivery.
Despite its widespread use, MSG has faced criticism and scrutiny regarding its safety. In the late 1960s, the term Chinese Restaurant Syndrome emerged after consumers reported symptoms such as headaches, flushing, and sweating after meals containing MSG. However, extensive scientific studies have largely debunked these claims, indicating that MSG is safe for the general population when consumed in typical amounts.
