100

This numerical value on the pH scale is considered neutral

What is 7?

100

This weak organic acid is the primary component found in vinegar.

What is acetic acid?

100

This simple tool uses color-changing paper to indicate a food’s acidity level.

What is indicator paper?

100

Regulating acidity is essential because it extends this aspect of food products.

What is shelf life?

100

This weak acid is formed when carbon dioxide dissolves in water, creating "fizz" in sodas.

What is carbonic acid?

200

Food acidity refers to the concentration of these ions in a product.

What are hydrogen ions?

200

Naturally found in citrus fruits, this acid is commonly used in coffee and meat products

What is citric acid?

200

Modern food production uses these electronic devices to measure acidity precisely in real-time.

What are pH meters?

200

Acidity regulation is often used to control these biological catalysts, such as Maltase.

What are enzymes?

200

This mineral acid is specifically used in the processing of vegetable oils and fats.

What is phosphoric acid?

300

On the pH scale, values below 7 are described by this term.

What is acidic?

300

This natural organic acid is found in fruits like apples and is used to enhance sour taste.

What is malic acid?

300

This chemical analysis method is one of the three main ways listed to measure food acidity.

What is titration analysis?

300

Besides taste, acidity regulation helps prevent the growth of these microscopic threats.

What are bacteria (or microorganisms)?

300

This salt of acetic acid is used to regulate acidity and control crystallization in maple syrup.

What is calcium acetate/calcium carbonate?

400

This term describes food with a pH value higher than 7.

What is alkaline/basic?

400

Grapes are the main natural source of this acid, which helps stabilize the taste of wine.

What is tartaric acid?

400

In large factories, these types of systems constantly adjust acidity by adding controlled amounts of acids or bases.

What are automated food processing systems?

400

Acidity regulation is critical for supporting this process, which is used to make products like fermented milk.

What is fermentation?

400

These chemical systems are used by food industries to keep pH levels stable.

What are buffer systems?
