Grape juice

Grape juice is liquid extracted from grapes, typically consumed without fermentation or used as an ingredient. Its sugars, acids, pigments, and aromas vary with grape variety and processing.

Juice extraction: The separation of liquid from fruits or other biological material by pressing, crushing, or related methods. Crushing and pressing release grape liquid while separating it from skins, seeds, and stems.
Glucose: A simple sugar that serves as a major energy source in living organisms. Glucose is one of the principal sugars that make grape juice sweet.
Concord grape: A dark-purple American grape cultivar known for its distinctive aroma and use in juice and jelly. Concord grapes are a common source of strongly flavored purple grape juice.
Food safety: The practices and conditions that prevent food from causing illness or injury. Unpasteurized juice can carry pathogens, making safe handling and treatment consequential.
Pasteurization: A heat treatment that reduces harmful microorganisms and spoilage organisms in food and drink. Heating grape juice helps prevent fermentation and extends its shelf life.
Fructose: A naturally occurring monosaccharide found in fruits and other foods. Fructose contributes sweetness alongside glucose in ripe grape juice.
White grape juice: Grape juice made from green or pale-skinned grapes, often with a lighter color and flavor. It is a distinct juice style used in drinks and food products.
Food preservation: Methods used to slow spoilage and extend the usable life of food. Heat, filtration, and packaging preserve grape juice after extraction.
Filtration: A separation process that removes suspended particles from a fluid by passing it through a filter. Filtration can clarify grape juice and remove solids before packaging.
Tartaric acid: An organic acid abundant in grapes and commonly used to regulate acidity in foods and drinks. It is a major source of grape juice’s characteristic acidity.
