Maltose vs. Sucrose: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on December 28, 2023
Maltose, a disaccharide of two glucose molecules, is less sweet, produced during starch breakdown; sucrose, a glucose-fructose disaccharide, is table sugar, naturally found in plants.

Key Differences

Maltose, known as malt sugar, is formed by two glucose units linked together. It is a product of starch digestion, commonly found in germinating grains and brewing processes. Sucrose, on the other hand, is a combination of glucose and fructose, widely known as table sugar. It is naturally present in many plants, especially in sugar cane and sugar beets, and is a primary source of sweetness in the human diet.

In terms of sweetness, maltose is considerably less sweet than sucrose. This characteristic of maltose makes it a preferred choice in certain food preparations where a mild sweetness is desired. Sucrose, with its higher sweetness level, is a dominant sweetener used in a wide range of food products, from baked goods to beverages.

Digestion and absorption of these sugars also differ. Maltose is broken down by the enzyme maltase into two glucose molecules, which are easily absorbed by the body. Sucrose, however, requires the enzyme sucrase to split it into glucose and fructose, which are then absorbed separately. This difference in digestion can have varying impacts on blood sugar levels.

In terms of usage, maltose finds its application mainly in brewing and in the production of certain Asian foods. Its ability to contribute to the fermentation process is highly valued in beer production. Sucrose, being a versatile sweetener, is ubiquitous in the food industry, from confectioneries to preservatives.

Sucrose

A common variety of sugar found in the juices of many plants, as the sugar cane, sorghum, sugar maple, beet root, etc. It is extracted as a sweet, white crystalline substance which is valuable as a food product, and, being antiputrescent, is largely used in the preservation of fruit. Called also saccharose, cane sugar, etc. At one time the term was used by extension, for any one of the class of isomeric substances (as lactose, maltose, etc.) of which sucrose proper is the type; however this usage is now archaic.
