 At present, Lide powder is mainly produced in China. Most of the domestic Lide powder production is still using traditional methods. The main raw materials are zinc oxide, sulfuric acid and barium sulfide (barite and coal are produced by high temperature reduction). Zinc 45% ~ 70%. The traditional method for producing the Liede powder process is to use zinc bakelite containing more than 45% zinc as a raw material to be leached with sulfuric acid to obtain a crude zinc sulfate solution, and then to remove iron by potassium permanganate, and then replace the heavy metal with zinc powder and filter to obtain zinc sulfate. The refined liquid is further subjected to metathesis reaction, pressure filtration, calcination, rinsing, drying, and pulverization with strontium sulfide to obtain a series of different types of lindose powder containing zinc sulfide of 30% or more. The whole process is carried out in an acidic (ra<7) environment, which consumes a large amount of sulfuric acid. The sulfuric acid has strong corrosiveness and requires high production equipment. The final discharged slag is acidic slag, which brings new pollution to the environment. High requirements, high production costs, and poor quality of the products obtained.

  • Mexican researchers sought to evaluate the effects of E171 across a span of conditions in mice, including its influence on behavior, along with the effects on the colon and liver. The research, published in 2020 in the journal Food and Chemical Toxicology, showed that E171 promoted anxiety and induced adenomas, or noncancerous tumors, in the colon. They also found that E171 heightened goblet cells hypertrophy and hyperplasia, which is typically seen in asthma patients and triggered by smoking or external pollutants and toxins. They also noted mucins overexpression in the mice, which can be linked to cancer cell formation.

  • Sorbic Acid as a Food Preservative An Overview


  • Moreover, the regulatory landscape surrounding food additives is constantly evolving. In many jurisdictions, the use of potassium chloride is carefully monitored to ensure that it is safe for consumption. Organizations like the Food and Drug Administration (FDA) in the United States and the European Food Safety Authority (EFSA) have established guidelines on the acceptable daily intake of potassium, taking into consideration the diverse needs of the population.


  • The safety of E150d, like many food additives, has been the subject of numerous studies conducted by food safety authorities, including the European Food Safety Authority (EFSA) and the U.S. Food and Drug Administration (FDA). E150d is generally recognized as safe when used within regulated limits. However, it's important to note that excessive consumption of caramel colorings, particularly in large quantities, may pose potential health risks, including allergic reactions in sensitive individuals.


  • Xanthan Gum's Role as an Emulsifier


  • E481, sodium stearoyl lactylate, is a versatile emulsifier widely used in the food industry, particularly in baking and dairy products. Its ability to stabilize mixtures, improve texture, and extend shelf life makes it an essential ingredient in many formulations. With a strong safety profile and continued relevance in food processing, E481 underscores the importance of food additives in delivering high-quality products to consumers. As the industry evolves, the role of such additives will remain critical in meeting both culinary and nutritional demands.


  • Dairy products are another significant source of naturally occurring glutamate. Cheese, particularly Parmesan and Roquefort, is rich in this amino acid. It contributes to the robust flavor profile of these cheeses, making them popular choices in a variety of culinary applications. Additionally, fermented dairy products like yogurt and certain types of aged cheese contain elevated glutamate levels resulting from the fermentation process, which releases glutamic acid from the protein structures.
