A single slice of bread contains 17 food additives! Boosting food safety awareness doesn’t mean we have to fear "additives" at every turn.

  Many foods in our daily lives contain food additives, yet recurring food safety scandals—such as melamine and Sudan Red—often cause the public to react with extreme caution whenever additives are mentioned. For instance, a slice of whole-grain bread may list as many as 17 food additives in its ingredient list, including calcium sulfate, vitamin C, carotene, calcium lactate, xylanase, malt extract, and amylase, while a single ice cream stick could even include up to 14 different additives. However, these legally approved food additives aren’t nearly as "scary" as they might seem.

  These legally approved additives, commonly used in food processing, pose no harm to human health. In contrast, well-known substances like melamine and Sudan Red are not classified as food additives—they are, in fact, illegal contaminants. Despite the significant distinction between the two, they are often mistakenly conflated with one another.

  In addition to food additives, beverage additives are also frequently encountered in children's daily lives. For instance, antioxidants help prevent or slow down the oxidation and breakdown of food ingredients—such as tea polyphenols in tea beverages, which not only inhibit discoloration but also preserve the tea’s aroma. Coloring agents, also known as food pigments, give foods their vibrant hues and enhance their visual appeal.

  Adolescents are at a critical stage of life development, and acquiring and developing scientifically informed food safety knowledge, attitudes, and practices (KAP) will shape their lifelong food safety habits, enhance their scientific literacy in this area, and help them approach food safety crises with greater rationality. During today’s science outreach class, the children participated in a hands-on "Rainbow Candy Experiment," gaining a clear, visual understanding of what food colorants are. Additionally, they deepened their awareness of why food safety is so crucial.

  A sixth-grade student shared that they just learned today that melamine isn’t actually a food additive—it’s an illegal substance added to foods, filling in a gap in their knowledge. Many other children also said they’ll now make it a point to check the ingredient lists on food packaging, paying close attention to details like food additives and expiration dates, so they can eat more healthily in the future.
