Galactooligosaccharide Powder (70%)

Galacto-oligosaccharide 70 powder usually refers to a powdered product with a galacto-oligosaccharide content of 70%.

I. Basic information.

1. Ingredients:

The main ingredient is galactooligosaccharide, and may also contain a small amount of other excipients or impurities depending on the production process and product standards.

2. Source and production:

Generally, lactose is used as a raw material and is produced by specific enzyme-catalyzed reactions and subsequent separation, purification and other processes. For example, Using β – galactosidase to act on lactose, connecting the galactose groups in lactose molecules to form oligogalactose.

II. Properties.

1. Physical and chemical properties.

1.1 Solubility:

Easily soluble in water to form a uniform solution.

1.2 Stability:

GOS 70 powder has a certain thermal stability and is relatively stable within a certain temperature range (normally under the common temperature conditions in food processing). However, it may decompose or change its properties under extremely high temperatures or strong acid and alkali conditions. It has relatively good acid and heat stability and will not decompose in a strong acidic environment with a pH of 2.0 or when heated to 180 °C.

1.3 Sweetness:

The sweetness is about 20-40% of sucrose, relatively low, and the taste is sweet and tasty.

2. Physiological functional characteristics.

2.1 Prebiotic function:

GOS 70 powder is an excellent source of nutrients and an effective proliferation factor for beneficial bacteria such as Bifidobacterium and Lactobacillus acidophilus. It can selectively promote the growth of lactobacilli and bifidobacteria while inhibiting the growth of pathogens, can improve the digestive and absorption function of the human intestine and maintain the balance of intestinal microecology.

2.2 Effect on intestinal health:

Galacto-oligosaccharide can promote human intestinal motility and improve the propulsion motility of the intestinal tract, which can excrete harmful substances from the human body in a timely manner. It can also be used by beneficial bacteria such as bifidobacteria in the intestinal tract to produce short-chain fatty acids such as acetic acid and lactic acid, which lower the pH value in the intestine and improve the intestinal environment.

2.3 Other health benefits:

Galacto-oligosaccharide is not digested and absorbed by the human body and is low in calories. It can be used as a kind of dietary fiber for weight control, and is not used by streptococci. It is degraded by oral enzymes, so it has the function of preventing dental caries. In addition, the acidic environment formed in the intestine can promote the excretion of harmful substances from the intestine, prevent the absorption of toxins into the blood, and thus maintain the health of blood vessels.

III. Application areas.

1. Food industry.

1.1 Dairy products:

Galacto-oligosaccharides are widely used in infant formula milk powder, yogurt, etc., which can improve the nutritional value of the product and improve the intestinal health of infants and young children. Internationally, galacto-oligosaccharide is one of the prebiotics allowed to be added to the “first stage milk powder” for infants and young children. In China, it is allowed to use in infant formula, infant formula for older infants and young children, and cereal supplementary food for infants and young children.

1.2 Baked foods:

Adding galactooligosaccharide to baked foods such as bread and cakes can improve their taste, texture and color, and their nutritional value is not lost when heated at high temperatures. Due to its low energy and indigestibility, it can reduce the incidence of obesity.

1.3 Candy:

Used to make functional candy to meet consumers’ needs for healthy candy.

1.4 Beverages:

Galactooligosaccharide can be added to various beverages such as milk drinks, fruit drinks, etc. to increase the functionality of the product.

2. Health products industry: GOS 70 powder can be used as a raw material for nutrition and health products to develop health products to regulate intestinal flora and enhance immunity.

3. Other industries: In the future, GOS is also expected to be used in special medical foods and green feeds as a substitute for antibiotics.
