Maltose vs. Maltodextrin — What's the Difference?
Edited by Tayyaba Rehman — By Urooj Arif — Updated on March 2, 2024
Maltose is a natural sugar composed of two glucose molecules, offering sweetness and energy, whereas maltodextrin is a polysaccharide used as a food additive, providing texture and a mild sweetness, but primarily used for its thickening.

Key Differences
Maltose, also known as malt sugar, is a disaccharide formed from two units of glucose linked together. It is produced when enzymes break down starches during the germination of seeds, such as barley, and in the process of brewing beer and distilling spirits. Maltodextrin, on the other hand, is a polysaccharide produced from starch by partial hydrolysis. It consists of glucose units linked in chains of varying lengths.
Maltose is less sweet than table sugar (sucrose) and is used in various food products for sweetness and flavor enhancement. Maltodextrin is widely used in the food industry as a thickener, filler, or preservative to increase the volume of processed foods, improve their texture, or stabilize their consistency. It is easily digestible, being absorbed as glucose, and is generally considered safe, but it offers little nutritional value.
While maltose contributes to the flavor profile of food and beverages, maltodextrin's role is more functional, affecting the physical properties of food products without significantly altering their taste. Maltodextrin can also serve as a quick energy source, but its primary use in food processing is not for sweetness or nutritional contribution but for its physical properties like thickening and binding.
Both maltose and maltodextrin are derived from natural starch sources through enzymatic processes. However, the extent of hydrolysis and the resulting molecular structure differ, leading to their distinct roles in food science and nutrition. Maltose is directly involved in energy metabolism as a sugar, while maltodextrin is more versatile, used in a wide range of products for its technical benefits rather than as a direct energy source.
In terms of health implications, consuming foods high in maltose or maltodextrin can affect blood sugar levels, making it important for individuals, especially those with diabetes, to monitor their intake. However, maltodextrin's impact on blood sugar can be more pronounced due to its faster absorption rate compared to maltose.

Common Curiosities
Is maltose healthier than maltodextrin?
Health implications depend on the context of the overall diet and individual health conditions. Both can affect blood sugar levels, but maltodextrin may have a more immediate impact due to its rapid absorption.
Are maltose and maltodextrin natural?
Both are derived from natural starches through enzymatic processes, but maltodextrin undergoes more processing, making it less "natural" than maltose.
Can maltose and maltodextrin be used interchangeably in recipes?
Not directly, as they serve different purposes in food preparation—maltose for sweetness and maltodextrin for texture and volume.
Do maltose and maltodextrin have the same effect on blood sugar?
Both can raise blood sugar levels, but maltodextrin may have a faster and more pronounced effect due to its structure and rapid digestion.
Can people with gluten intolerance consume maltose and maltodextrin?
Maltose and maltodextrin are gluten-free if derived from gluten-free sources, but products containing these ingredients should be checked for overall gluten content.
Are there any allergic reactions associated with maltose or maltodextrin?
Allergic reactions to maltose and maltodextrin are rare, but individuals with specific food sensitivities or allergies should be cautious and consult with a healthcare provider, especially since maltodextrin can be derived from various sources, including corn, wheat, and potato.
How are maltose and maltodextrin labeled in ingredient lists?
Maltose may be listed as "maltose" or "malt sugar" in ingredient lists. Maltodextrin is typically listed as "maltodextrin." If maltodextrin is derived from wheat, it may be labeled specifically to alert those with gluten sensitivities.
Can maltose and maltodextrin contribute to weight gain?
Yes, like all carbohydrates, both maltose and maltodextrin can contribute to weight gain if consumed in excess without adequate physical activity, as they provide energy (calories).
How do maltose and maltodextrin differ in their production processes?
Maltose is produced through the enzymatic breakdown of starch during processes like seed germination and brewing. Maltodextrin is made by partial hydrolysis of starch, which involves breaking down the starch into shorter chains of glucose units under controlled conditions.
Do maltose and maltodextrin have any functional benefits in baking?
In baking, maltose can contribute to the Maillard reaction, enhancing flavor and color of baked goods. Maltodextrin can act as a filler or texturizer, improving the mouthfeel and structure of products like cakes and cookies.
Are maltose and maltodextrin considered sugars?
Maltose is considered a sugar (a disaccharide), while maltodextrin, although derived from starch and composed of glucose units, is classified as a polysaccharide and not a sugar in the nutritional sense.
Is maltodextrin considered a complex carbohydrate?
Yes, maltodextrin is considered a complex carbohydrate due to its polysaccharide structure, despite being quickly digestible and having a high glycemic index similar to some simple sugars.
Why is maltodextrin used in sports drinks and energy gels?
Maltodextrin is used in sports drinks and energy gels because it is easily digestible and provides a quick source of energy without the immediate spike in blood sugar that simple sugars cause, making it ideal for sustained energy release during exercise.
How do maltose and maltodextrin affect individuals with diabetes?
Both maltose and maltodextrin can affect blood sugar levels, which is a concern for individuals with diabetes. They should monitor their intake of these carbohydrates as part of their overall management of blood sugar levels.
How do the caloric contents of maltose and maltodextrin compare?
Both maltose and maltodextrin provide calories (about 4 calories per gram, similar to other carbohydrates), but the impact on diet and satiety can differ based on the food product's overall composition and how these ingredients are used.
Are maltose and maltodextrin vegan-friendly?
Yes, both maltose and maltodextrin are vegan-friendly as they are derived from plant-based starches. However, individuals following a vegan diet should still check product labels for other non-vegan ingredients.
How do maltose and maltodextrin impact gut health?
The impact of maltose and maltodextrin on gut health can vary. While excessive intake of easily fermentable carbohydrates can disrupt gut balance, moderate consumption as part of a diverse diet may not have significant adverse effects. However, some studies suggest maltodextrin can alter gut bacterial balance and potentially increase the risk of intestinal inflammation or infection.
How should individuals with celiac disease approach foods containing maltose or maltodextrin?
Individuals with celiac disease should ensure maltose and maltodextrin are derived from gluten-free sources, such as corn or potatoes. While pure maltose and maltodextrin are gluten-free, cross-contamination or wheat-based sources can pose risks, so it's important to check labels or consult manufacturers.
Is there a dietary advantage to choosing foods with maltose over maltodextrin?
The dietary advantage depends on individual dietary needs and health goals. Maltose, being a sugar, provides energy but can also affect blood sugar levels. Maltodextrin, while it has a less pronounced taste, can still impact blood sugar and is often used in processed foods, which might not align with all dietary preferences.
Can maltose and maltodextrin be part of a healthy diet?
In moderation, maltose and maltodextrin can be part of a healthy diet, especially when balanced with a variety of foods from all food groups. However, limiting added sugars and highly processed foods is generally recommended for overall health.
