A

S

Acesulfame potassium

Sweeteners

A high-intensity sweetener also called Ace-K. On Indian and international labels it may appear by name, as E950, or as INS 950, often alongside other sweeteners.

Acidity

Coffee · Tasting

The lively quality that can remind you of citrus, apple, grape, or berries. It is not the same as a sour brewing fault.

Acidity regulator

Additives

An ingredient used to control the acidity or alkalinity of a food. It can affect flavor, shelf life, texture, and how other ingredients behave.

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.

AeroPress

Coffee · Brewing

A compact brewer that combines immersion with gentle hand pressure. Paper or metal filters can be used.

Agave syrup

Sweeteners

A sweet syrup made from agave. In packaged foods it contributes sugar and bulk, so the nutrition panel matters more than its plant-derived name.

Agitation

Coffee · Brewing

Movement from pouring, stirring, or swirling. More movement usually helps water pull flavour faster.

Amino acid profile

Protein

The pattern of amino acids in a protein source. It matters because protein quality depends on both total grams and the amount of essential amino acids the body can use.

Anticaking agent

Additives

An ingredient added to powders, salts, spice blends, grated cheese, or drink mixes to reduce clumping and keep the product free-flowing.

Antifoaming agent

Processing

A processing aid or additive used to reduce foam during manufacturing, cooking, frying, or filling.

Antioxidant

Additives

An ingredient used to slow oxidation, which can make oils taste rancid, change color, or reduce shelf life. In label reading, it is a function, not automatically a health claim.

Arabica

Coffee · Plant

Aroma

Coffee · Tasting

What the coffee gives your nose. Smell the dry grounds, the wet brew, and the cup as it cools.

Artificial color

A colorant made or purified for food use rather than obtained as a simple whole-food ingredient. Clean-label readers usually check whether color is there for identity, appeal, or masking poor ingredients.

Artificial flavor

Flavor

A flavoring substance that does not meet the label rules for natural flavor in the market where it is sold. It tells you origin category, not whether the flavor is simple or complex.

S

Artificial sweetener

Sweeteners

A high-intensity sweetener used to create sweetness with little or no sugar. It often appears in diet drinks, protein products, chewing gum, and low-sugar desserts.

Ascorbic acid

Additives

A form of vitamin C used as a nutrient, antioxidant, flour improver, or browning control agent depending on the product.
