Product Introduction
Advanced spray drying technology is used by Shaanxi Zhenhuacui Biotechnology to give food-grade Bulk alfalfa powder that has 98% flavonoids (HPLC confirmed). Our production edge is that we are dual-certified for cGMP and FSSC22000, we can extract supercritical CO₂, and we have a 60% R&D team whose job it is to make sure that every batch is the same. Standards include particles with a size of 80 to 100 mesh, a moisture content of less than 5%, and stable for 24 months. We've been making plant extracts for more than 10 years and can help businesses with everything from 1 kg R&D samples to multi-ton production. Our normal collection ships within 10 days.

Important technical factors are:

Verified Potency
Third-party HPLC tests on each batch show that it contains 98% flavonoids. Our powder is different from others because it goes through supercritical CO₂ extraction, which is a pharmaceutical-grade process that concentrates bioactives while getting rid of leftovers.
Manufacturing Credibility
Cleanrooms that meet pharmaceutical standards are used for cGMP-certified production.
Application-Ready Format
Fine powder with an 80–100 mesh size melts quickly in cold liquids and doesn't clump when used in drinks. Tested in citrus drinks to see if it stays stable in acidic pH and can handle heat up to 80°C for 30 minutes.

Testing Capabilities:

Step 1: Raw Material Control
The alfalfa used for our Bulk alfalfa powder is sourced from approved farms. Only plants picked at 10% bloom stage, which is the best time for flavonoids to be present.
Step 2: Extraction
Heat-sensitive chemicals are kept safe during supercritical CO₂ extraction at 35°C. No liquid left over.
Step 3: Spray Drying
It's 180°C coming in and 80°C going out. Makes a powder that flows easily and has less than 5% wetness.
Step 4: Quality Release
Before it was released, each batch was checked for identity, purity, strength, and bacterial safety.
