In the world of food preservation and enhancement, various additives play crucial roles in ensuring the safety, quality, and longevity of food products. Among these additives, E301, commonly known as sodium ascorbate, stands out for its multifunctional properties. Derived from ascorbic acid, or vitamin C, sodium ascorbate is not only a powerful antioxidant but also a vital ingredient in a variety of food 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.
Uses in Medical Applications
In laboratories, concentrated glacial acetic acid is an indispensable reagent. It is often utilized in the synthesis of various organic compounds and serves as a solvent for reactions where a strong acid is required. Furthermore, it is used in titrations to determine the concentration of bases or other alkaline substances. Its role as a dehydrating agent in organic synthesis is also noteworthy, particularly in the production of anhydrides and acetates.
In addition to its adhesive capabilities, UF resin is characterized by its quick drying time, which enhances production efficiency. The resin can be produced in various formulations, allowing manufacturers to tailor its properties for specific applications, such as varying the ratio of urea to formaldehyde to modify the resin's hardness and setting time.
The primary benefit of using E282 is its ability to extend shelf life. For food manufacturers, this translates to reduced food waste, lower costs, and enhanced product appeal due to prolonged freshness. For consumers, this means they can purchase products that remain safe and palatable over a more extended period. Additionally, E282 is effective at low concentrations, which minimizes its impact on taste, making it a preferable choice for many food applications.
4. Sorbic Acid Although not a traditional acid, sorbic acid is often used in conjunction with other preservatives to inhibit mold and yeast growth in baked goods, cheeses, and beverages.
Aspartame, labeled as E950, is another sweetener frequently used in low-calorie and sugar-free products. As one of the most studied artificial sweeteners, aspartame has been deemed safe for consumption by various health authorities. It is approximately 200 times sweeter than sugar, which means a very small amount is needed to achieve the desired sweetness. However, some individuals may have sensitivities to aspartame, leading to headaches or other side effects. For those on a keto diet, it is essential to monitor one's tolerance and response to aspartame, especially since it is primarily used in carbonated beverages and sugar-free products that may contain other non-keto-friendly ingredients.
