Food additive series - maltodextrin

Release time:


1. Introduction

Maltodextrin (MD), a polysaccharide food raw material, is a low-conversion product between starch and starch sugar. Its raw materials are starchy corn, rice, etc., and can also be refined starch, such as corn starch, wheat starch, tapioca starch, etc. The main ingredient is dextrin, and contains polysaccharides, tetrasaccharides or more oligosaccharides, and also contains small amounts of maltose and glucose. It is an amorphous powder with white or slightly yellow appearance, no impurities visible to the naked eye, special odor, and no sweet or slightly sweet taste.

2. Specifications

Its series of products are based on different DE values, and the common product specifications are: MD10, MD15, MD20, etc.

The physical properties of maltodextrin are directly related to the DE value of its hydrolysis, so the DE value not only indicates the degree of hydrolysis, but also is an important indicator to grasp the characteristics of the product. Generally speaking, the higher the degree of hydrolysis of maltodextrin, the greater the DE value, the greater the dissolved oxygen, sweetness, permeability, fermentability, browning reaction and freezing point drop of the product, and the worse the structure, viscosity, pigment stability and anti-crystallization of the product.

3. Use

Maltodextrin is added to dairy products such as milk powder, which can make the product volume expand, not easy to agglomerate, instant solubilization, good preparation, extend the shelf life of the product, reduce costs and improve economic benefits. It can also improve the ratio of nutrients, increase the price of nutrients, and be easy to digest and absorb. The role of maltodextrin in the preparation of functional milk powders, especially sucrose-free milk powders, infant booster milk powders, etc., has been confirmed. Dosage 5%~20%.

Used in soybean milk powder, instant cereals and malt milk essence and other nutritious snack foods, it has a good taste and instant thickening effect, avoids precipitation and stratification, can absorb beany smell or milk smell, prolong the retention period, and the reference dosage is 10%~25%.

It is used in solid beverages, such as milk tea, fruit crystals, instant tea and solid tea, which can maintain the characteristics and flavor of the original product, reduce costs, mellow and delicate product taste, rich flavor and aroma, excellent instant dissolution effect, and inhibit crystal precipitation. The emulsification effect is good, and the carrier effect is obvious. The reference dosage is 10%~30%. The amount of maltodextrin DE24~29 suitable for the production of coffee mate can be as high as 70%.
Used in fruit juice drinks, such as coconut milk juice, peanut almond milk and various lactic acid drinks, the emulsification ability is strong, the original nutritional flavor of fruit juice remains unchanged, it is easy to be absorbed by the human body, the viscosity is improved, the product is pure, the stability is good, and it is not easy to precipitate. Used in sports drinks, maltodextrin is used in the metabolism of the human body, the consumption of heat energy is easy to maintain balance, and the load of digestion and absorption of the stomach and intestines is small. The reference dosage is 5%~15%.
Used in frozen foods such as ice cream, ice cream or popsicles, the ice particles are delicate and delicate, the viscosity is good, the sweetness is mild, there is little or no cholesterol, the flavor is pure, the mouth is refreshing, the taste is good, and the dosage is 10%~25%.

When used in candy, it can increase the toughness of candy, prevent sand return and callowing, and improve the structure. Reduce the sweetness of candy, reduce dental disease, reduce tooth sticking, improve flavor, prevent deliquescent, and extend the shelf life, the dosage is generally 10%~30%.
It is used for biscuits or other convenience foods, with full shape, smooth surface, bright color and good appearance. The product is crispy and delicious, moderately sweet, does not stick to the teeth, does not leave residue, has few defective products, and has a long shelf life. Dosage 5%~10%.

Maltodextrin is used in all kinds of canned or soup soups to increase consistency, improve structure, appearance and flavor. It is used in solid seasonings, spices, powdered oils and other foods, playing the role of dilution and filling, and can prevent moisture from agglomerating, so that the product is easy to store. It can also play a role as a substitute for grease in powder grease.
Adding maltodextrin to meat products such as ham and sausage can reflect its strong viscosity and thickening characteristics, making the product delicate, rich in taste, easy to package and form, and prolong the shelf life. Dosage 5%~10%.
