Where Ingredients Appear
Look up where additives like sodium benzoate, titanium dioxide, carrageenan, Red 40, BHA, and calcium propionate appear in foods.
Intro
Many ingredient searches start with a shelf-level question: what foods contain this additive, and is it common enough to watch for again? This hub maps recurring additive names to the food categories, functions, and label cues that make the linked IngrediCheck profiles easier to use.
Why It Matters
Where-used searches sit between broad additive education and a single product scan. A dedicated hub helps shoppers move from queries like "foods with sodium benzoate" or "where is Red 40 used" into sourced profiles that explain function, diet notes, regulatory context, and practical label checks.

Featured Ingredients
Start with the ingredient profiles
preservative
Sodium benzoate
Sodium benzoate is a preservative used in acidic beverages, sauces, condiments, and shelf-stable products. It keeps microbes down, which is why it remains common even when consumers increasingly associate it with older soft-drink controversies.
dye
Titanium dioxide
Titanium dioxide is a whitening and opacity agent used to make icings, candies, sauces, and supplements look brighter and more uniform. It became a household ingredient topic after Europe decided food use was no longer acceptable.
thickener
Carrageenan
Carrageenan is a seaweed-derived thickener used in dairy alternatives, chocolate milk, deli meat, whipped toppings, and desserts. It is useful in manufacturing because it helps liquids stay smooth and suspended.
thickener
Xanthan gum
Xanthan gum is a fermentation-derived thickener that shows up in gluten-free baking, sauces, dressings, and frozen desserts. It is often the ingredient that gives wheat-free products enough structure to hold together.
emulsifier
Lecithin
Lecithin is a broad label term for phospholipid-rich emulsifiers used in chocolate, baked goods, dressings, infant foods, and supplements. The source can be soy, sunflower, egg, or less commonly animal tissue.
preservative
Calcium propionate
Calcium propionate is a mold-inhibiting preservative commonly used in bread, buns, tortillas, and other packaged baked goods. It matters because it sits at the center of a real shelf-life tradeoff between softer bread products and simpler ingredient decks.
preservative
BHA
BHA is a synthetic antioxidant preservative added to fats and oils in snacks, cereals, gum, and other packaged foods. It is useful for shelf life, but it also carries one of the most persistent reputational and toxicology debates in the food supply.
preservative
BHT
BHT is a synthetic antioxidant preservative used to protect fats and oils from oxidation in cereals, snacks, gum, and other shelf-stable foods. It matters because it often appears in the same product ecosystem as BHA and has become part of the wider re-evaluation of older synthetic preservatives.
sweetener
Sucralose
Sucralose is a high-intensity sweetener used in diet drinks, flavored dairy, protein products, tabletop packets, and low-sugar baking mixes. It is popular because it is intensely sweet, shelf-stable, and easy to formulate around.
sweetener
Acesulfame potassium
Acesulfame potassium is a high-intensity artificial sweetener used in zero-sugar drinks, gum, protein products, and reduced-sugar packaged foods. It matters because it is a common formulation tool in modern ultra-processed products even when shoppers do not always recognize the label name.
dye
Red 40
Red 40 is the most widely used synthetic food dye in the United States and shows up across sports drinks, candy, cereal, frosting, and snack products. It matters because it is common, not because every single use case is identical.
dye
Yellow 5
Yellow 5 is a synthetic dye used in chips, drinks, dessert mixes, and other products that want a bright yellow or orange tone. It often appears alongside other petroleum-based dyes rather than as a one-off ingredient.
dye
Yellow 6
Yellow 6 is a widely used orange-yellow synthetic dye found in chips, candy, bakery fillings, beverages, and snack foods. It matters because it is one of the easiest colors for shoppers to spot in mass-market products even when it does not dominate the public conversation like Red 40.
dye
Blue 1
Blue 1 is a synthetic petroleum-derived food dye used to create vivid blue shades in sports drinks, candy, frostings, freezer pops, and novelty snacks. It matters because it is easy to spot on labels and has become part of the broader retailer and regulatory shift away from synthetic colors.
preservative
Propylparaben
Propylparaben is a preservative used to slow spoilage in certain processed foods, especially where fat and moisture make shelf life fragile. It draws attention because the United States and Europe have treated the ingredient very differently.
additive
Potassium bromate
Potassium bromate is a flour improver that can strengthen dough and improve loaf volume in commercial baking. It is one of the clearest examples of an ingredient that remains legal in parts of the U.S. while many other markets have already rejected it.
additive
Azodicarbonamide
Azodicarbonamide is a flour treatment agent used to strengthen dough handling and promote a more uniform crumb in commercial bread products. It is more famous in public debate for where it is banned than for what bakers use it to do.
emulsifier
Brominated vegetable oil
Brominated vegetable oil is a beverage emulsifier once used to keep citrus flavor oils suspended in soft drinks and flavored beverages. It matters because it became one of the rare additive stories that mainstream shoppers could easily understand and that regulators, states, and retailers all eventually moved against.
