Process Description
Raw Material Preparation
Flaxseed is thoroughly cleaned, destoned, magnetically separated, and cold pressed to recover premium edible oil. The resulting defatted meal is finely milled and conditioned for protein extraction.
Cold Oil Pressing
Cold pressing preserves the nutritional quality of flaxseed oil while producing protein-rich meal for downstream processing.
Advantages include:
- Premium omega-3 oil recovery
- Low-temperature processing
- Improved protein concentration
- Reduced oxidation
- Higher overall profitability
Mucilage Recovery
A specialized extraction process separates valuable flaxseed mucilage before protein extraction.
Recovered mucilage is widely used in:
- Functional foods
- Bakery products
- Nutraceuticals
- Pharmaceutical formulations
- Cosmetic products
Protein Extraction
Protein is extracted under optimized alkaline conditions to maximize recovery while preserving functional properties.
Benefits include:
- High protein recovery
- Excellent emulsification
- Superior water-binding capacity
- Improved digestibility
- Consistent product quality
Membrane Filtration
Ultrafiltration and diafiltration systems remove:
- Soluble carbohydrates
- Minerals
