What extraction methods preserve vitamin C content best?

Freeze-drying and low-temperature water extraction methods provide optimal vitamin C retention. We introduce buyers to processors using controlled temperature extraction (<60°C) and immediate stabilisation to maintain ascorbic acid potency throughout shelf life.

Can you source rosehip extracts with specific standardisation levels?

Yes, we can introduce suppliers of extracts standardised to various marker compounds including 5-20% vitamin C, specific phenolic content, or custom concentration ratios. HPLC analytical methods confirm standardisation levels with each batch COA.

What are typical lead times for EU-organic certified rosehip extracts?

EU-organic rosehip extracts typically require 2-4 weeks lead time depending on harvest season and processing schedules. Peak availability occurs September-November following harvest, with processed materials available year-round from inventory.

How do you ensure consistent particle size for capsule applications?

Processors in our network use calibrated milling and screening equipment to achieve specified mesh sizes (typically 80-120 mesh for capsules). Particle size distribution analysis is included in batch documentation to verify flowability characteristics.
