The advantages of using sodium metabisulfite in food preservation are manifold. Its ability to act as an effective antioxidant is paramount; it prevents rancidity in fats and oils, which extends the shelf life of various food items. Furthermore, sodium metabisulfite's role in preventing enzymatic browning in fruits and vegetables keeps them looking appealing and fresh.

On the other hand, synthetic stabilizers, such as xanthan gum and carrageenan, are widely used in the food industry due to their effectiveness and versatility. Xanthan gum, derived from the fermentation of glucose by the bacteria Xanthomonas campestris, is commonly used in salad dressings, sauces, and gluten-free baked goods. It helps to prevent the separation of oil and vinegar in dressings and provides a creamy mouthfeel without altering the flavor of the product. Similarly, carrageenan, extracted from red seaweed, is often used in dairy products, non-dairy creamers, and processed meats to improve texture and maintain moisture.

One of the most common uses of deuterated solvents is in the field of organic chemistry, where they are used to dissolve complex organic compounds. In reactions involving these compounds, it is crucial to isolate characteristics of the product without the added noise from the solvent. Deuterated solvents allow chemists to achieve higher resolution and sensitivity in their NMR analyses, enabling more accurate structural elucidation and quantification of compounds.
