Active cultures

Fermentation

Live microorganisms added to foods such as yogurt, kefir, kimchi, or fermented drinks. The label should make clear whether cultures are live at the time of sale or simply used during processing.

Nutrition

Sugar added during manufacturing, cooking, or preparation, separate from sugars naturally present in whole fruit, milk, and other intact foods.

S

Additive

Additives

A substance added for a technological purpose, such as preserving, coloring, thickening, sweetening, stabilizing, or improving texture.

S

Additive class

Label literacy

The functional job an additive performs, such as emulsifier, preservative, stabilizer, antioxidant, color, sweetener, or acidity regulator.

Grain milled to remove the bran, germ, or both. It usually has less fiber and fewer naturally occurring micronutrients than the intact whole grain.

Resistant starch

Fiber

Starch that resists digestion in the small intestine and can be fermented in the large intestine. It may occur naturally or be added as an ingredient.

Rice syrup

Sweeteners

A starch-derived syrup made from rice. On a label, it usually plays the role of sweetener and binder.

Rosemary extract

Additives

An extract often used for antioxidant function, especially in oils, snacks, meats, and pet foods. It may appear for shelf-life reasons, not just flavor.

S

Salt

Minerals

Sodium chloride, used for flavor, preservation, dough behavior, fermentation control, and texture. If you are watching salt, read the sodium line as well as the ingredient list.

Salt substitute

Minerals

An ingredient or blend used to reduce sodium while keeping salty taste. Potassium chloride is a common example.

Saturated fat

Fats

A type of fat found in animal fats, tropical oils, dairy, and many processed foods. It appears on nutrition panels because fat type matters, not just total fat.

Seasoning blend

Flavor

A compound ingredient that can contain salt, sugar, spices, flavors, anti-caking agents, yeast extracts, oils, acids, and flavor enhancers.

Seed oil

Fats

Oil extracted from seeds such as soybean, sunflower, canola, cottonseed, sesame, or grapeseed. The useful label question is the oil type, refinement, use level, and product context.

Serving size

Nutrition labels

The amount used to calculate nutrition numbers on the panel. It may be smaller than what people actually eat, so per-100g comparisons are often clearer.

Snack plate

Colloquial

An informal plate built from small items such as crackers, cheese, fruit, nuts, dips, leftovers, or prepared snacks. Treat it like a meal if it replaces one: check protein, fiber, produce, fat, and total portion.

Shelf-stable

Processing

A product that can be stored at room temperature before opening. Shelf stability may come from heat treatment, drying, acidity, preservatives, packaging, or water activity control.

Silicon dioxide

Additives

An anticaking and flow agent used in powders, seasonings, grated cheese, supplements, and drink mixes.

Smoke flavor

Flavor

A flavoring ingredient used to create smoky notes without traditional smoking. It may appear in meats, sauces, snacks, cheeses, and plant-based products.

A curing ingredient used in some processed meats for color, flavor, and microbial control. It is a high-attention term in label audits.

pH 0 14

Sodium phosphate

Additives

A phosphate ingredient used for water binding, texture, emulsification, leavening, or pH control depending on the food.

Soluble fiber

Fiber

Fiber that dissolves or disperses in water. It can affect viscosity, fermentation, satiety, and blood-glucose response depending on the type.

Sorbitol

Sweeteners

A sugar alcohol used as a sweetener and humectant in sugar-free candy, gum, baked goods, and some supplements.

Soy lecithin

Emulsifiers

Lecithin derived from soy, commonly used to improve mixing, flow, and texture in chocolate, baked goods, spreads, and powders.

Sprouted grain

Grains

Grain that has begun germinating before drying or milling. It can change flavor, texture, and nutrient availability, but the whole ingredient list still matters.

Stabilizer

Texture

An ingredient that helps maintain a product's structure, texture, suspension, or uniformity over time.

Starch syrup

Sweeteners

A syrup made from broken-down starch. It may be used for sweetness, body, gloss, browning, or binding.

S

Stevia

Sweeteners

A high-intensity sweetener derived from stevia leaf compounds. It is often blended with carriers or other sweeteners because very small amounts are needed.

Sweeteners

A high-intensity sweetener used in low-sugar foods, drinks, protein powders, and supplements. Its presence is a cue to check the full sweetener system, not just the sugar grams.

Sugar

Sweeteners

A simple carbohydrate used for sweetness, bulk, browning, fermentation, and texture. Check total sugar, added or free sugar where available, and sugar aliases in the ingredient list.

Sugar alcohol

Sweeteners

A carbohydrate sweetener such as erythritol, sorbitol, xylitol, maltitol, or isomalt. It can reduce sugar grams while still shaping taste, texture, and digestion.

Sugar-free

Claims

A claim that a product meets the market's definition for very low sugar content. It does not mean unsweetened, additive-free, or calorie-free.

Sunflower lecithin

Emulsifiers

Lecithin derived from sunflower, used as an emulsifier in chocolate, spreads, powders, and baked goods. It is often used as an alternative to soy lecithin.

Supplement

Supplements

A product sold to add nutrients, botanicals, amino acids, or other substances to the diet. Clean-label reading checks dose transparency, excipients, sweeteners, and claims.

OIL H₂O

Surfactant

Food science

A substance that helps reduce surface tension between ingredients, often supporting emulsification, foaming, or wetting.

Sweeteners

The full mix of ingredients used to create sweetness, body, and aftertaste control. A product may combine sugar, polyols, fibers, and high-intensity sweeteners.

T

OIL H₂O

Textured vegetable protein

Protein

Plant protein processed into a fibrous or chewy texture, often used in meat alternatives, fillings, and high-protein prepared foods.

Thickener

Texture

An ingredient that increases viscosity. Thickeners can make products feel richer even when water, starch, or gums are doing much of the work.

Titanium dioxide

Color

A white colorant historically used in some foods, supplements, and confectionery. It is a regulatory watch-list term because rules differ across markets.

Tocopherols

Additives

Vitamin E compounds often used as antioxidants to protect oils and fat-containing foods from oxidation.

The nutrition-panel line that includes starches, sugars, fibers, and sugar alcohols depending on the label format. It is harder to game than front-label carb claims.

Trans fat

Fats

A fat type associated with partially hydrogenated oils and some naturally occurring ruminant fats. It is a key label line and ingredient-list check.

U

Ultra-filtered

Processing

Filtered through membranes to concentrate or remove selected components. It is often used in dairy to change protein, lactose, and mineral levels.

Ultra-pasteurized

Processing

Heated to a higher temperature than standard pasteurization for a shorter time, usually to extend shelf life in dairy and cream products.

Ultra-processed

A formulation typically made with industrial ingredients, additives, flavor systems, and processing methods that go beyond ordinary home cooking.

Unbleached flour

Grains

Refined flour that has not been chemically bleached. It is still usually refined unless the label also says whole grain or whole wheat.

Unsweetened

Claims

A claim that no sweetening ingredient has been added for sweetness. It is different from no added sugar and should still be checked against the ingredient list.

V

OIL H₂O

Vegetable glycerin

Texture

Plant-derived glycerin used as a humectant, solvent, sweet-tasting carrier, or texture aid in foods and supplements.

Vitamin

Fortification

A blend of vitamins added to a food, drink, or supplement. It can improve micronutrient numbers while leaving the base product highly processed.

W

Water activity

Food science

A measure of how much water is available for microbial growth and chemical reactions. It is one reason dried, salted, sugared, or syrupy foods keep longer.

Whey protein

Protein

A milk-derived protein from cheesemaking. It is used in powders, bars, drinks, yogurts, and snacks for protein content, solubility, and texture.

Whole food

Whole grain

Grains

A grain ingredient containing the bran, germ, and endosperm. Look for the word whole attached to the specific grain, not just brown color or grain imagery.

X

Xanthan gum

Texture

A fermentation-derived gum used to thicken, suspend, and stabilize foods such as sauces, dressings, gluten-free baked goods, drinks, and dairy alternatives.

Xylitol

Sweeteners

A sugar alcohol used in chewing gum, candies, oral-care products, and some low-sugar foods. It provides sweetness and bulk with different labeling behavior than sugar.
