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.

Fermentation is another age-old method of preservation that aligns with the principles of healthy eating. Fermented foods like kimchi, sauerkraut, and yogurt not only boast extended shelf lives but are also rich in probiotics, which contribute positively to gut health. The natural processes involved in fermentation create an environment inhospitable to harmful bacteria, thus naturally preserving the food while enhancing its nutritional profile.

Emulsifiers play a vital role in the food industry, helping to mix ingredients that usually don’t combine well, such as oil and water. Among various emulsifiers, E442 (Glycerol esters of fatty acids) and E476 (Polyglycerol esters of fatty acids) are commonly used. Both serve important functions in food products, ensuring stability, texture, and consistency.

One of acetone's primary roles in the rubber industry is as a solvent in the formulation of rubber products. When rubber is processed, acetone can help dissolve certain polymers, making it easier to mix ingredients and create a homogenous blend. This is particularly relevant when formulating adhesives and sealants, where consistency and uniform distribution of components are critical for performance. The effective solvency of acetone enables manufacturers to create materials with tailored properties, suitable for specific applications.
