Pure Inulin powder is a natural dietary fiber widely used in food, health products, and other fields. Many factors affect the shelf life of inulin bulk powder. Guanjie Biotech is one of the pure inulin powder manufacturers. The following insights on the preservation of inulin will elaborate on the shelf life of inulin and related influencing factors under different conditions.
Shelf life of unopened inulin
•Under ideal storage conditions
Bulk inulin powder produced from Jerusalem artichoke as raw material can usually be stored for about 2 years. If its inulin content is 90%, in a dry, cool, and well-ventilated storage environment with a temperature of 15℃-25℃ and a relative humidity of 40%-60%. This is because,e in such an environment, the chemical structure of inulin is relatively stable. The growth and reproduction of microorganisms can also be well inhibited, and it is not easy to deteriorate, agglomerate, etc.
Bulk powder made from chicory with an inulin content of 95% may have a slightly longer shelf life. About 2.5 to 3 years. Higher inulin content is more stable. This is less susceptible to quality changes due to external factors.
•Under normal storage conditions
When the storage environment temperature is 25℃-35℃ and the relative humidity is 60%-80%, the shelf life of products with 90% artichoke inulin powder may be shortened to about 1.5 years in an unopened state. Higher humidity may cause inulin to absorb moisture from the air, causing it to clump. Higher temperatures will also accelerate the chemical reaction rate of inulin, reducing its stability.
For inulin with 95% inulin content from chicory, the shelf life may be about 2 years when unopened. Although its purity is high, it will also be affected to a certain extent in a relatively poor storage environment. However, due to its purity advantage, the shelf life will still be slightly longer than that of inulin from Jerusalem artichoke with a lower content.
•Under extreme storage conditions
If the storage environment temperature is higher than 35℃, or the relative humidity is higher than 80%, or even in a humid and high-temperature environment, the inulin bulk powder with 90% inulin content from Jerusalem artichoke may have quality problems within 1 year or even less if it is unopened. Such as yellowing, odor, severe caking, etc.
Inulin with 95% bulk chicory inulin content can relatively resist some harsh environments. But under such extreme conditions, the storage time will be greatly shortened to about 1.5 years. This may lead to problems such as decreased purity and excessive microorganisms.
Shelf life of opened inulin
•In a dry environment
If it is placed in a dry indoor environment, the temperature is 15℃-25℃, the relative humidity is 40%-60%, and it can be sealed in time after use. 90% organic Jerusalem artichoke inulin powder can usually be stored for 3-6 months. During each use, minimize the contact time with air to effectively prevent it from absorbing moisture and being oxidized.
Inulin with 95% inulin content from chicory may be stored for 6-9 months in the same dry environment. The high purity makes it more stable in a dry environment and is not easily affected by a small amount of moisture and oxygen from the outside.
• In an ordinary indoor environment
The general indoor environment temperature is 20℃-30℃, the relative humidity is 50%-70%, and if special moisture-proof measures are not taken after opening, the shelf life of inulin with 90% inulin content from Jerusalem artichoke may only be 2-4 months. In such an environment, inulin will gradually absorb moisture in the air, causing changes in its physical and chemical properties. This will cause deliquescence, agglomeration, and other phenomena.
The storage time of 95% inulin from chicory in an ordinary indoor environment is about 4-6 months after opening. Although its purity is high, it will also be affected by environmental humidity and temperature over time, resulting in quality degradation.
• In a humid environment
If the opened inulin bulk powder is placed in a humid environment, the relative humidity is often higher than 70%. The 90% Jerusalem artichoke inulin powder made may seriously absorb moisture and agglomerate within 1-2 months, and may even breed microorganisms and deteriorate.
The storage time of 95% inulin from chicory in a humid environment will not exceed 3 months after opening. It will also face problems such as moisture absorption, agglomeration, and microbial contamination. Its high purity can only delay the occurrence of these problems to a certain extent, but it cannot be completely avoided.
Other factors affecting the shelf life of inulin
• Packaging form
Bagged: Ordinary plastic bag packaging has relatively limited protection for inulin. Even if it is unopened, it is easily affected by the external environment and the shelf life will be relatively short. Aluminum foil bag packaging has good barrier properties and can effectively block moisture, oxygen, and light, which can extend the shelf life of inulin. Whether before or after opening, it can be stored longer than inulin packaged in ordinary plastic bags. Guanjie Biotech uses 1 kg aluminum foil bag packaging. Of course, we can also customize it.
• Barrel packaging:
Plastic barrels or iron barrels with good sealing properties. It can provide better protection for inulin when it is not open and is suitable for large-scale storage of inulin. However, after opening, if the sealing measures are not in place, the inulin will have a large contact area with the air, and the shelf life will be affected.
• Cleanliness of storage container
If the container for storing inulin bulk powder is not clean, there will be other impurities or microorganisms left. Even if the inulin itself is of good quality, it will be contaminated during storage. This will accelerate deterioration and shorten the shelf life. Therefore, before storing inulin, it is necessary to ensure that the container is clean and sterile.
• Impact of the transportation process
During the transportation process, if inulin is affected by adverse factors such as high temperature, humidity, and extrusion, it may be damaged to a certain extent before reaching the destination.
Signs of deterioration of inulin
During storage, if inulin is not stored properly, the following signs of deterioration may occur:
• Appearance changes
Inulin tends to form lumps after absorbing moisture. The darkening of color may be due to oxidation or microbial contamination.
• Odor changes
Inulin may absorb foreign odors or produce foreign odors due to microbial action.
• Functional changes
Moisture absorption and agglomeration will reduce the water solubility of inulin. Inulin may become rough in taste after being exposed to moisture.
