- Food additives. Thousands of substances and chemicals are added to the processed foods we eat every day. We’re talking about preservatives, anti-caking agents, colors, emulsifiers, stabilizers, thickeners, flavor enhancers, artificial sweeteners, coloring agents, and more. Food companies must demonstrate that these additives do not pose a risk to human health prior to marketing. But a large number of additives were first approved decades ago and have never been reevaluated. And food safety advocates contend additives introduced to the market today do not undergo sufficient testing to determine whether they significantly elevate the risk of chronic disease.
- Acesulfame potassium. Acesulfame potassium [CAS No. 55589-62-3], also known as acesulfame K or Ace K, is an artificial sweetener used to sweeten a wide variety of low- and reduced-calorie foods and beverages. Acesulfame K is approximately 200 times sweeter than sucrose and both intensifies and extends sweetness and other flavors. In order to mask its bitter aftertaste, manufacturers often blend acesulfame K with aspartame and sucralose, the other major artificial sweeteners on the market today. Unlike aspartame and sucralose, acelsufame K is stable when heated, which makes it particularly useful for sweetening baked goods and products that require a long shelf life, such as alcoholic beverages, protein shakes, condiments, toothpaste, mouthwash, and chewable and drinkable medications.
- Bentonite nanoclay. Bentonite nanoclay is a type of engineered nanoparticle known as nanoclay. Nanoclays have a flaky soft structure, low specific gravity, and high aspect ratio with nanoscale thickness that make them particularly useful in polymer packaging. Nanoclays have been shown to improve the mechanical, thermal, and barrier properties of polymer systems, all of which can help extend the shelf life of packaged food products. Bentonite nanoclay is also used as a processing aid in the manufacture of vegetable oils and beverages.
- Carrageenan. Carrageenan [CAS No. 9000-07-1] is an emulsifying, thickening, and stabilizing agent used in food and personal care products. An indigestible polysaccharide extracted from a red seaweed known as Irish Moss, carrageenan is found in a wide array of food products including ice cream, yogurt, cottage cheese, chocolate milk, infant formula, soups, sauces, puddings, and plant-based milk products such as soy, almond, coconut, and hemp milk.
- Cellulose nanofibrils. Cellulose nanofibrils, also referred to as nanocellulose, is a material composed of nanosized (5–20 nanometer) cellulose fibrils. Owing to their nanosize, cellulose nanofibrils have unique characteristics that make them behave like a pseudo-plastic with the properties of a gel or fluid that is viscous under normal conditions, but flows over time when shaken, agitated, or otherwise stressed. High viscosity at low concentrations makes nanocellulose useful as a non-caloric thickener, flavor carrier, and stabilizer in processed foods such as low-calorie whipped toppings, cake frostings, salad dressings, gravies, and sauces. Cellulose nanofibrils can be produced from cotton, wood, grasses, and other abundant biomass making them an inexpensive alternative to petroleum-based polymers for use in food packaging materials.
Updated Litagion agent profiles based upon newly published science
All Litagion agent profiles have been updated to reflect the most recently published peer-reviewed science. Notable scientific studies added to CoMeta since the last release include:
- Bisphenol A (BPA). A meta-analysis using National Health and Nutrition Examination Survey (NHANES) data from 2003-2016 reports a significant association between BPA exposure and cardiovascular disease.
- Oxybenzone. A study of 625 women in California and Utah reports a significant correlation between urinary levels of oxybenzone and endometriosis.
In addition, we highlight the following changes to the components of Litagion agent risk resulting from newly published peer-reviewed science:
|Risk category change
|Overall risk change
|Bis(2-ethylhexyl) tetrabromophthalate (TBPH)
|Projected science risk changes from Low (green) to Medium-low (light green)
|Projected science risk changes from Medium-low (light green) to Medium-high (orange)
