Acetone, a simple organic compound with the formula (CH₃)₂CO, is an important solvent in various industries due to its ability to dissolve many substances. One of the materials that acetone interacts with is rubber, a versatile material found in countless applications, from tires to medical devices. Understanding the relationship between acetone and rubber is vital for industries that depend on rubber components.

In addition, the production of L-cysteine from human hair has sparked controversy. While the process is deemed safe and the end product is purified, the idea of consuming a food additive derived from human hair can be unsettling for many consumers. This underscores the importance of transparency in food labeling—consumers should be able to make informed choices about what they are consuming.

Carrageenan is extracted from several species of red algae, primarily Chondrus crispus (Irish moss) and Eucheuma cottonii. The extraction process involves boiling the seaweed, followed by filtration and drying to obtain a fine powder. There are three main types of carrageenan kappa, iota, and lambda. Each type has unique gelling properties and is used for different purposes. Kappa carrageenan forms a strong gel in the presence of potassium ions, making it ideal for dairy products. Iota carrageenan, on the other hand, creates softer gels and is typically used in puddings and sauces. Lambda carrageenan does not gel but is an excellent thickening agent, often used in salad dressings and sauces.

Conclusion

In addition to its role in sweetening, aspartame enhances flavors in various processed foods. For instance, it can be found in yogurt, breakfast cereals, and even some medications. Because of its versatility, aspartame plays a crucial role in the low-calorie food market, providing an option for those looking to maintain a balanced diet without sacrificing taste.

Another remarkable flavor enhancer is five-spice powder. This aromatic blend usually includes star anise, cloves, Chinese cinnamon, Sichuan peppercorns, and fennel seeds. Its warm, pungent aroma adds depth and complexity to meats, marinades, and stews. The five-spice powder exemplifies the Chinese philosophy of balancing flavors, allowing a harmonious blend of sweet, sour, bitter, and salty notes in a single dish.

Now imagine the delicate skin on your face, on your children’s arms & legs. Each day un-knowingly, thinking we are doing the right thing, we slather them up with titanium dioxide in the form of sunscreen & send them out into the sun, all the while never knowing that once exposed to light titanium dioxide creates free radicals that are strong enough to damage steel roofing panels!!

In its statement to USA TODAY, the FDA maintained that, in all post-approvals for food additives, our scientists continue to review relevant new information to determine whether there are safety questions and whether the use of such substance is no longer safe under the Federal Food, Drug, and Cosmetic Act.

Le lithopone est produit par coprécipitation de sulfure de baryum et de sulfate de zinc, le plus souvent en proportions équimolaires, puis grillage de la pulpe résultante⁴.

For a mini-review published in the journal Particle and Fibre Technology in 2021, scientists wanted to evaluate whether Ti02 particles contributed to the development and/or exacerbation of irritable bowel disease, and whether they altered the four elements of intestinal barrier function: the intestinal microbiota, the immune system, the mucus layer, and the epithelium. The breakdown of these four elements can contribute to autoimmune, neurological, inflammatory, infectious, and metabolic diseases. Following their review, the researchers concluded: “Data indicate that TiO2 is able to alter the four compartments of IBF and to induce a low-grade intestinal inflammation associated or not with pre-neoplastic lesions.” 

In 2022, a year after the EFSA recommended against the use of E171, the Food Standards Australia New Zealand (FSANZ) conducted its own reassessment of titanium dioxide as a food additive. The agency concluded that titanium dioxide was indeed safe to use as a food additive. The United Kingdom and Canada came to similar conclusions.

Lithopone is the re-discovered white pigment with functional properties suitable for several applications.

In a review published in 2022 in the journal Archives of Toxicology, researchers found that the ingestion of E171 is a “a definite health risk for consumers and their progeny.” After reviewing dozens of in vivo, ex vivo and in vitro studies on the toxicity of E171, the researchers wrote that two facts must be noted: “First, reprotoxicity studies show that animals of both sexes are impacted by the toxicity of these nanoparticles, underlining the importance of conducting in vivo studies using both male and female animals. Second, human exposure begins in utero via maternal-fetal transfer and continues after birth by breastfeeding. Children are then chronically re-exposed due to their food preferences. To be relevant to the human in vivo situation, experimental studies should therefore consider nanoparticle exposure with respect to the age or life period of the studied population.”

Over the last several years, nanoparticles have come under scrutiny for adverse health effects. Nanoparticles are ultrafine particles between 1 to 100 nanometers in diameter. (To put this in perspective, the average human hair is around 80,000 nanometers thick.) Because of their size, which can be engineered and manipulated at the atomic or molecular level, nanoparticles exhibit unique physical, chemical, and biological properties. Titanium dioxide is one of the most commonly produced nanoparticles in the world.

In order to achieve the same solids content, the larger filler and the binder should be reduced if necessary.  

Drobne et al. used the terrestrial arthropod Porcellio scaber as a test organism for determining the cytotoxic effect of TiO₂ NPs (anatase). The animals were exposed to TiO₂ NPs of two different sizes (25 nm and 75 nm) in the concentration range 10–1000 μg TiO₂/g dry food for 3 to 14 days. No adverse effects, such as mortality, body weight changes or reduced feeding, were observed. In fact, quite the opposite, an enhanced feeding rate, food absorption efficiency and increase in catalase activity were observed. The intensity of these responses appeared to be time- but not dose-dependent. It should also be noted that the concentrations tested in this study were much higher than the predicted concentration (4.8 μg/g soil) at high emission scenario of nano-sized TiO₂. Using the same test organism another group showed that exposure to TiO₂ NPs induced destabilization of cell membrane in the epithelium of digestive glands isolated from exposed animals. They also showed that this effect can be observed after just 30 minutes of exposure.
