Overview
Mass Medicata Fermentata Extract, known as Liuqu in Chinese medicine, is produced through the fermentation of wheat, rice, and other grains with herbal additives. This traditional preparation has been used for centuries to treat digestive stagnation and spleen deficiency. As a complex botanical extract, it contains active enzymes, beneficial microbial metabolites, and phytochemicals from the fermentation process. Modern applications extend beyond classical TCM into nutraceuticals and functional foods targeting gut health.
Physical and Chemical Properties
The extract typically appears as a hygroscopic brown powder with a characteristic fermented aroma. Its composition varies based on substrate grains and fermentation strains, but generally includes amylases, proteases, and microbial transformation products. Quality indicators include enzyme activity levels (typically 50-200 U/g for amylase) and absence of pathogenic microorganisms. Unlike single-compound pharmaceuticals, this extract's efficacy derives from synergistic interactions among its multiple active components.
Main Applications
In TCM practice, Liuqu Extract is primarily prescribed for food stagnation patterns, often combined with herbs like Hawthorn and Radix Aucklandiae. It helps promote digestion of starches and proteins while regulating intestinal flora. Pharmaceutical manufacturers incorporate it into digestive aid formulations, while nutraceutical companies use it in gut health supplements. Some functional food producers add it to fermented beverages or cereal products for digestive benefits.
Safety and Storage
The extract has an excellent safety profile when used appropriately. Standard precautions for botanical extracts apply - those with grain allergies should exercise caution. Properly stored material maintains stability for 2-3 years. Storage requires protection from humidity (recommended RH <60%) and temperatures below 25°C. Bulk packaging should use food-grade containers with desiccants to prevent clumping and microbial growth during extended storage.
B2B Procurement Guide
Professional buyers should prioritize suppliers with GMP certification for herbal extracts. Key evaluation points include: fermentation process documentation, microbial testing results (total count <10,000 CFU/g), and absence of heavy metal contamination. For international buyers, verify export compliance regarding botanical materials. MOQ typically starts at 25kg, with discounts available for 100kg+ orders. Consider requesting samples for HPLC fingerprint analysis to compare different suppliers' product profiles.
