Specifications:
It commonly presents as a light - yellow to beige fine powder. Its powdery form makes it convenient for storage, transportation, and further processing in different applications.
Identification is achieved through multiple analytical means. High - performance liquid chromatography (HPLC) is a key technique to separate and quantify the various polypeptide components in the powder. Mass spectrometry (MS) can further determine the molecular weights and structural details of these polypeptides, helping to confirm their identities. Additionally, biochemical assays may be used to detect specific biological activities associated with the polypeptides.
Polypeptide Content: The proportion of effective polypeptides is a crucial quality indicator. High - quality products usually have a relatively high polypeptide content, often reaching 80% or more, which directly affects its biological activity and functionality.
Loss on Drying: This value is strictly controlled, generally kept below 5%. A low loss on drying ensures the powder's stability, preventing moisture - related degradation or caking during storage.
Heavy Metals and Impurities: Stringent limits are set for heavy metals such as lead, mercury, and cadmium, as well as other impurities. Heavy - metal content is typically required to be extremely low, often less than a few parts per million (ppm), to guarantee safety for use, especially in health - care and food - related applications.
Microbiological Quality: Microbiological parameters, including total aerobic microbial count, yeast and mold count, and the absence of pathogenic microorganisms, are closely monitored. This is essential to ensure the product's safety and extend its shelf - life.
In the medical and health - care fields, earthworm polypeptide drying powder is known for its potential thrombolytic and anti - inflammatory effects. The polypeptides may help break down blood clots, making it a promising ingredient in products for preventing and treating thrombotic diseases. It also shows potential in promoting tissue repair and enhancing immune function. In the food industry, due to its rich nutritional and bio - active properties, it can be used as a functional additive in some health - promoting food products.
