maltose
RareScientific/Technical, Food Industry
Definition
Meaning
A sugar formed from two glucose molecules, found in malt and used as a sweetener.
A disaccharide sugar produced by the enzymatic hydrolysis of starch, commonly associated with brewing and digestion.
Linguistics
Semantic Notes
The term is highly specific to biochemistry and food science; rarely used in general conversation.
Dialectal Variation

Usage
Context Usage
Business
Used in product specifications for food or brewing ingredients (e.g., 'This syrup has a high maltose content.').
Academic
Common in biochemistry, nutrition, and food science textbooks and papers (e.g., 'The enzyme amylase breaks starch down into maltose.').
Everyday
Virtually unused. Might appear on specialist food labels or in dietary discussions (e.g., 'Some people have difficulty digesting maltose.').
Technical
The primary domain. Used precisely to describe a specific carbohydrate molecule in metabolic pathways and industrial processes.
Examples
By Part of Speech
verb
British English
- This enzyme will maltose the starch.
- The process maltosed the complex carbohydrates.
American English
- The enzyme maltosed the starch.
- We need to maltose these grains for the syrup.
adverb
British English
- The starch was hydrolysed maltosely.
- The reaction proceeded maltosely.
American English
- The starch was hydrolyzed maltosely.
- The reaction proceeded maltosely.
adjective
British English

Examples
By CEFR Level
- Maltose is a type of sugar.
- Some sugar in food is called maltose.
- Beer contains maltose from the barley.
- The body breaks down starch into simpler sugars like maltose.
- The production of high-maltose syrup is crucial for certain confectionery items.
- Unlike sucrose, maltose consists solely of two glucose molecules.
- The enzyme's specificity for cleaving alpha-1,4 glycosidic bonds to yield maltose was demonstrated in vitro.
- Industrial fermentation processes often rely on feedstocks with high levels of readily fermentable sugars such as maltose.
Learning
Memory Aids
Mnemonic
Think of MALT (from barley) + OSE (the suffix for sugars like glucose). The sugar from malt.
Conceptual Metaphor
Often conceptualised as a 'building block' or 'intermediate product' in the process of breaking down starch into energy.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid confusing with 'мальтоза' (the direct cognate, correct). Do not translate as 'солодовый сахар' (malt sugar) in formal scientific contexts where the precise term is required.
Common Mistakes
- Incorrect stress on the first syllable ('MAL-tose'). Correct stress is on the first syllable, but with a longer vowel in UK English. Misspelling as 'maltos', 'maltosee', or 'moltose'.

FAQ
Frequently Asked Questions
No. Table sugar is sucrose (glucose + fructose). Maltose is glucose + glucose and is less sweet.
It is found in malted grains (like barley), some corn syrups, and is produced in the human body during starch digestion.
Most people can, using the enzyme maltase. A rare condition called congenital maltase-glucoamylase deficiency can cause problems.
Yeast ferments maltose into alcohol and carbon dioxide, making it a key sugar in beer production.
