  • While nitrogen fertilizers are essential for crop production, their use is not without environmental consequences. Over-application can lead to nitrogen leaching into water bodies, causing eutrophication—a process that depletes oxygen in aquatic ecosystems and leads to harmful algal blooms. These blooms can disrupt aquatic life, contaminate drinking water supplies, and result in significant economic losses for fisheries and tourism.


  • Sorbitan esters, also known by their commercial name Span, are another category of emulsifiers frequently used in food preparation. These esters are derived from sorbitol and fatty acids, and they work well in stabilizing oil-in-water emulsions. For instance, sorbitan monostearate is often employed in cakes and whipped toppings to provide stability and improve mouthfeel. Furthermore, their low toxicity and ability to withstand high temperatures make them suitable for various cooking applications.
