Uses of Citric Acid in Food Products
3. Cosmetics The cosmetic industry in China also utilizes sodium metabisulfite as an antioxidant and preservative in various products. Its ability to prevent the oxidation of active ingredients makes it valuable in formulating stable and effective skincare and beauty products.
E202, also known as potassium sorbate, is a widely-used food preservative that plays a crucial role in extending the shelf life of various products. It is a potassium salt of sorbic acid and is recognized for its ability to inhibit the growth of mold, yeast, and some bacteria. As food preservation technologies have evolved, E202 has emerged as a preferred additive in the food industry due to its effectiveness and safety profile.
Emulsifiers play a crucial role in the food industry and other sectors, acting as agents that stabilize mixtures of oil and water, which naturally tend to separate. Among these emulsifiers, E481, also known as sodium stearoyl lactylate, is widely used due to its effective properties and versatility.
Potassium sorbate breaks down into its potassium and sorbate ions, and may also form sorbic acid and sorbitol. In fact, it is commonly produced by reacting sorbic acid with potassium hydroxide. As mentioned above, the equilibrium concentrations of the dissociated ions and acid are dependent upon the pH, which is why potassium sorbate loses efficacy at a pH above 7.
It is the salt derivative of sorbic acid, an unsaturated fat that's also used as a food preservative.
Moreover, in the realm of dietary and health-conscious foods, these agents enable the production of low-fat and reduced-calorie alternatives. By mimicking the creamy textures of fat using thickeners or gelling agents, manufacturers can create appealing products that cater to specific dietary needs without sacrificing flavor or mouthfeel.
The Role of Acids as Food Preservatives
2. Preservative Due to its ability to prolong shelf life, sodium ascorbate is commonly used as a preservative in various products. It helps inhibit the growth of bacteria and mold, contributing to the overall safety of food items.

The safety of food additives, including E20200, is a topic of considerable importance. Regulatory agencies worldwide, such as the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA), have assessed the safety of potassium sorbate. Both organizations have deemed it safe for use within specified limits. It is important to note that while E20200 is generally recognized as safe, excessive consumption can lead to potential adverse effects, including allergic reactions in sensitive individuals.
Polybutadiene rubber (PBR) is a synthetic rubber derived from the polymerization of 1,3-butadiene. It is a key player in the world of elastomers due to its unique properties, which make it suitable for a wide range of applications. This article discusses the characteristics, production process, and various uses of polybutadiene rubber.
Conclusion
Public awareness and concern regarding food safety have increased dramatically in China, particularly after several high-profile food safety scandals. Incidents involving toxic additives or mislabeling of products have led to widespread distrust among consumers. As a response, the government has ramped up its efforts to educate the public on safe food practices and the appropriate use of additives. Campaigns aimed at raising awareness about food quality and safety issues are now commonplace, encouraging consumers to be proactive and informed about what they consume.

In conclusion, E621, or monosodium glutamate, serves primarily as a flavor enhancer rather than a traditional preservative. While it enhances the taste of many processed foods, contributing to their palatability and potentially reducing food waste, it does not inhibit spoilage or extend shelf life in the same way traditional preservatives do. The safety of MSG has been affirmed by numerous health authorities, but ongoing discussions about food additives highlight the importance of consumer choice and transparency in labeling.
