There is almost no caramelization, no side reactions. Because we use a rice with some amylopectin, we get different functionalities than you would from rice grown in the South. According to Obanni, rice maltodextrins made from non-chemical mechanical and enzymatic processes resist retrogradation to a greater degree.
With enzymatic hydrolysis, process factors come into play, but the specific enzyme used also impacts the end result. For example, alpha-amylase attacks the linkages of starch the main chain of amylopectin or amylose. Other enzymes, such as isoamylase, catalyze the hydrolysis of the bonds and act as "debranching" enzymes. In general, acid hydrolysis tends to produce more sugars, such as dextrose and maltose, which means they will promote browning.
By controlling the various factors, manufacturers control the degree of hydrolysis, and obtain a consistent product. Still, most commercial maltodextrins are a mixture of different carbohydrate polymers.
The disaccharide profile that is created influences the properties of the maltodextrin. However, maltodextrins are usually classified by DE. The DE offers the food designer a guide to the properties these ingredients exhibit. The analysis is a measurement of the average reducing power compared to a dextrose standard.
DE indicates the degree of polymerization DP of the starch molecule - the number of monosaccharide units in the molecules. The higher the DE, the higher the level of monosaccharides and short chain polymers.
Glucose dextrose possesses a DE; starch is approximately zero. Because maltodextrins and other hydrolyzed starches consist of a mixture of polymer lengths, the DE is an average value. In a maltodextrin, it may only be one-tenth of that. Since a maltodextrin with a low DE contains a larger amount of longer straight- and branched-chain units, it tends to exhibit characteristics more in line with those of starch, such as viscosity.
As the DE increases and the level of lower molecular weight products increases, the maltodextrin tends to act more like a corn syrup solid. This means that a number of characteristics of maltodextrins are related to the DE. Within these ranges, the ingredients will not show significant differences in functionality. Armstrong notes that while it's difficult to find any differences with a small shift in DE, larger differences indicate greatly different polymer lengths.
The characteristics of a 5 DE are vastly different from those of an 18 DE. As DE increases, so do the following characteristics:. Most commercial maltodextrins are spray-dried and sold as powders, although some liquid maltodextrins are available. If you buy it as a liquid product in most cases, it's partially formulated - by that I mean that the final use is going to be in a product that requires preservatives or acid in the end product.
The spray-drying procedure and one additional process - agglomeration - also influence the characteristics of a particular maltodextrin product.
The method and conditions of spray-drying will affect the particle size and shape, and the resulting surface area. Typical bulk densities of standard spray-dried maltodextrins range from approximately 0. And since some of that surface area is interstitial, if you get colors and flavors there, they're more protected.
For agglomeration, the surface of the individual particles are moistened to provide tackiness, and processed so they fuse together. Agglomerating the particles reduces the bulk density from approximately 0. The larger, more porous structure increases the void volume, and creates a lower surface-to-volume ratio. It improves flowability, dispersion and wettability, and also decreases dusting.
Standard maltodextrin product would not flow under the same test conditions. Sander, president, Zumbro Inc. Acids can be sprayed on during the fluid bed process to match or modify the pH of the final solution. Co-agglomerating other ingredients with maltodextrins helps ensure uniform distribution of small amounts of ingredients in the final mix. It also can modify viscosity, and aid in the effective hydration of gums and other viscosifiers. Co-agglomerated, both gum and carrier disperse simultaneously.
Maltodextrins act as dispersing aids, flavor carriers, bulking agents, humectants, viscosifiers and other functional ingredients. They can work in a wide variety of applications - from dry mixes to fillings and sauces to beverages.
Due to their osmolality, they can be a valuable source of nutritive carbohydrates. The functional characteristics related to DE help determine the applications where maltodextrins are used. A study found that a digestion-resistant form of maltodextrin called Fibersol-2 was effective at significantly inhibiting human colorectal tumor cell growth.
There are two theories for why this is so — it may be that bacterial fermentation caused by the presence of the maltodextrin is responsible, and it may be due to improvements in digestion attributed to maltodextrin see below.
Research also shows that digestion-resistant maltodextrin helps to relieve constipation and support regular bowel function — it generally keeps things moving. This may seem contradictory, given the previously-mentioned research linking maltodextrin to bowel disease, but the concerns lie mostly with the easily digested form of maltodextrin.
Many things in life have pros and cons, and maltodextrin is no exception. Whether you choose to consume it, include it as a digestive aid, or use it to pump up your athletic endurance, is a good topic of discussion with your doctor or nutritionist. These 27 ideas for using leftover wine prove that it's both satisfying and resourceful. Okra is a fuzzy green vegetable filled with seeds that's full of antioxidants, vitamins, and minerals.

Prune juice is a common home remedy for constipation, but it also has plenty of other health benefits. Here's the science behind its biggest benefits….
However, if a person eats too many products that contain maltodextrin, their diet is likely to be high in sugar, low in fiber, and full of highly processed foods. Maltodextrin has an even higher glycemic index GI than table sugar. A spike in blood glucose can be particularly dangerous for people with diabetes or insulin resistance. A high GI means that the sugars in these foods will quickly enter the bloodstream, where the body will absorb them.
In contrast, complex carbohydrates, which include beans and whole-wheat pasta, are more healthful because the body absorbs them slowly. This makes people feel full for a more extended period. Although studies in humans are necessary to confirm this, initial research on mice suggests that people who consume maltodextrin may have a reduced number of good bacteria and an increased quantity of harmful bacteria. This could potentially lead to intestine damage and a higher risk of inflammatory bowel diseases.
Another study has linked maltodextrin to the survival of Salmonella bacteria, which may cause gastroenteritis and a broad range of chronic inflammatory conditions. A recent study suggested that maltodextrin may also compromise the ability of cells to respond to bacteria. It could also suppress intestine defense mechanisms against them, leading to intestinal disorders. Many food additives can cause allergies or intolerances. Side effects may include allergic reactions, weight gain, gas, flatulence , and bloating.
Maltodextrin may also cause a rash or skin irritation, asthma , cramping, or difficulty breathing. The primary sources of maltodextrin will be corn, rice, and potato, but manufacturers may sometimes use wheat. People with celiac disease or gluten intolerance should be aware that, although the production process will remove most of the protein components, maltodextrin derived from wheat may still contain some gluten.
There is also a chance that the genetically modified material can get into wild plants and animals, or into the human body through the diet. There is little evidence that this is true, though some believe that the lack of evidence could be partly due to the censorship of GMO research.
The Environmental Sciences Europe journal published an article in support of this theory. Maltodextrin is a cheap and effective food product that can improve the texture, taste, and shelf life of foods. Many athletes and people who want to gain muscle or body weight use products containing maltodextrin as it is a rapid source of energy.
People who are concerned about their maltodextrin intake may wish to choose alternative foods that provide healthful nutrients. Because maltodextrin is rapidly digested, it can be added to sports drinks or supplements as a fast energy source for athletes and bodybuilders. FYI, regular maltodextrin provides calories and is digested like any other sugar, while resistant maltodextrin is similar to dietary fiber, per Fibersol That said, there are more widely studied ways to prevent colon cancer.
According to the Mayo Clinic , these lifestyle changes can reduce your risk of colon cancer:. It was also a small study with only 66 adults. Plus, you'll typically find the additive in processed foods, which do not promote healthy digestion as well as whole foods, per Johns Hopkins Medicine.
Instead, these are the best ways to improve your digestion naturally, per the Cleveland Clinic :. It can be. Maltodextrin derived from gluten-free ingredients like corn or potato starch is naturally gluten-free. If wheat is used to make maltodextrin, it has to be listed in the label's allergen statement or ingredients list.
But even then, maltodextrin made with wheat is generally considered safe for people with celiac disease because the gluten is removed during processing, per the National Celiac Association. You can find products that use additives other than maltodextrin by looking at the ingredients list. According to the Academy of Nutrition and Dietetics , food thickeners, stabilizers and gelling agents include:.
When cooking at home, you may use thickeners, stabilizers and gelling agents to create stiffness, stabilize emulsions or form gels. You can do so with egg yolks, yogurt, gelatin, mustard and vegetable purees, per the Academy of Nutrition and Dietetics.
You also don't necessarily need supplements before a workout: You can get a carbohydrate boost by having a glass of fruit juice, a cup of yogurt or an English muffin with jelly before exercising if you'll be working out for more than an hour, per the U. National Library of Medicine. Maltodextrin is generally considered safe and more research is needed to confirm any negative health impacts. However, it is often in processed foods that can raise your risk for obesity and other chronic health problems.
The bottom line: It's best to limit foods made with maltodextrin to occasional treats. Not specifically because they contain the additive, but because they're usually highly processed foods that are less healthy than whole foods. Nutrition Nutrition Basics Nutrition Facts.
