Where Does Shiitake Extract Powder Come From?

What Is The Extraction of Shiitake Extract Powder?

Shiitake extract powder is typically made by extracting lentinan, a natural polysaccharide found in the fruiting body or mycelium of Lentinula edodes. The process focuses on separating and concentrating this active compound to create a stable, high-quality ingredient. In most production lines, the raw shiitake material is cleaned, crushed, and soaked before undergoing hot-water extraction. This step allows lentinan to dissolve into the liquid. The shiitake extract powder is then filtered, concentrated, and spray-dried into a fine powder with consistent purity and activity. Guanjie Biotech is a professional lentinan supplier. We use a controlled water-extraction method to ensure safety, reliability, and stable quality for bulk shiitake extract powder.

●Raw material selection:

We chose dried Lentinula edodes for extraction. Dried Lentinula edodes has more concentrated nutrients and is often used for industrial extraction.

●Extraction and hydrolysis:

The raw materials of Shiitake Extract Powder are initially treated by steaming, hot water soaking and other methods to extract water-soluble polysaccharides.

●Separation and purification:

Ultrafiltration, dialysis and other technologies are used to purify polysaccharides to remove impurities and obtain high-purity shiitake polysaccharides.

●Drying treatment:

Finally, we concentrate shiitake polysaccharides into powder form by spray drying and freeze-drying.

 

Chemical composition and structure

The main component of Shiitake Extract Powder polysaccharides is β-glucan, which is a complex polysaccharide molecule. The structure is mainly composed of glucose units connected by β-1,3 and β-1,6 glycosidic bonds. These β-glucan molecules can not only play a role through various biological pathways but also enhance the function of the immune system.

Linensis polysaccharides also contain a small amount of other sugars, amino acids, proteins and trace elements. These components work together to produce the multiple biological activities of shiitake polysaccharides.

 

Does Shiitake extract powder dissolve in water?

The water solubility of Shiitake extract powder is an important basis for its biological activity, nutritional content and application effect. The main component of shiitake polysaccharides is β-glucan. Its water solubility is closely related to its molecular structure. The following are the water solubility characteristics of shiitake polysaccharides.

•Solubility characteristics of β-glucan

β-glucan, the basic component of Lentinan, is a polysaccharide composed of glucose molecules connected by β-1,3 and β-1,6 glycosidic bonds. The water solubility of β-glucan mainly depends on its molecular weight, molecular structure and its branched structure.

Due to the large molecular weight of β-glucan, Lentinan usually has good water solubility. Especially in warm or low-temperature water. The solubility of Lentinan in water is affected by temperature, pH value and salt concentration. For example, as the temperature increases, the solubility of shiitake extract powder increases. Therefore, it can be dissolved more easily at 60°C-70°C.

 

•Factors that improve water solubility

The solubility of Lentinan depends not only on its molecular structure but also on the extraction process and powder particle size. After Lentinan is powdered by spray drying, freeze drying and other processes, its water solubility can be significantly improved. In addition, the smaller the particle size of Lentinan powder, the faster the dissolution rate and the better the water solubility.

 

•Importance of water solubility

The water solubility of shiitake extract powder directly affects its absorption and bioavailability in food and health products. When it is water-soluble, Lentinan can quickly enter the human body. Therefore, when Lentinan is used as a functional food additive, it is usually necessary to ensure its good water solubility to achieve the best effect on the human body.

 

How Is Shiitake extract powder stability?

The stability of shiitake extract powder is the key to its ability to maintain its activity and efficacy during production, storage and use. Its stability involves many aspects, including thermal stability, oxidative stability, light stability and pH stability. The following are several important aspects of Lentinan stability.

 

•Thermal stability

The thermal stability of lentinus edodes extract powder refers to the ability of shiitake mushroom extract powder to maintain its structure and biological activity during heating. β-glucan usually has good thermal stability, but may degrade at extremely high temperatures. Studies have shown that Lentinan can maintain good stability at temperatures below 100°C. After heating in hot water for 30 minutes, its biological activity and water solubility did not change much. However, at higher temperatures, such as above 120°C, the molecular structure of Lentinan may be damaged, resulting in reduced biological activity.

Therefore, in the processing and application of shiitake extract powder, excessive temperatures should be avoided as much as possible to ensure its stability. For example, when producing health foods or beverages with a high content of Lentinan, controlling the processing temperature is an important measure to ensure its effect.

 

•Oxidative stability

It may undergo oxidative degradation in an oxidative environment. Especially when exposed to air, the activity of organic shiitake mushroom extract powder may be affected. Oxidation reactions can lead to the destruction of certain functional groups in Lentinan. This can reduce its functions such as immunomodulation.

 

•Light stability

It has poor light stability. Especially under ultraviolet irradiation, Lentinan may undergo photodegradation. Long-term exposure to strong light may cause photodegradation reactions of glucose molecules in Lentinan. This can lead to structural changes and functional losses. Therefore, during the production, storage and transportation of lentinan 30 shiitake extract, direct sunlight should be avoided, and light-shielding packaging should be used to reduce the impact of light on its stability.

 

•pH stability

It has strong pH stability and is more stable in neutral to weakly acidic environments (pH 4-7). When the pH is lower than 4, the molecular structure of shiitake extract powder may be affected to a certain extent, which leads to a decrease in its solubility and biological activity. Under alkaline conditions, the stability of linenin may also be affected.

 

•Storage stability

The storage stability of shiitake extract powder is closely related to its storage environment. To maintain its water solubility and biological activity, it should be stored in a dry, cool, dark, and low-temperature environment. Generally speaking, lentinus edodes extract can be stored for a long time under low temperature and dry conditions. However, in a humid, high-temperature or light-exposed environment, the stability of shiitake extract bulk may be significantly reduced.
