The Challenges
● High Free Fatty Acid (FFA) content requires more intensive neutralization processes, which can be costly and complex.
● Presence of Phytosterols and Tocopherols can complicate the refining process
● High wax content can cause cloudiness and need to be removed to improve oil clarity and quality
● Strong color and odor that needs to be removed to meet consumer preferences and market standards, which requires effective decolorization and deodorization processes.
● The oil's stability can be impacted by the high levels of unsaturated fatty acids and the presence of compounds like oryzanol.
● Refining rice bran oil involves multiple steps, including degumming, neutralization, bleaching, and deodorization. Each step must be carefully controlled to avoid loss of valuable nutrients and to ensure the final oil meets quality standards.
● The refining process can produce waste products and by-products, such as soapstock and spent bleaching earth, which need to be managed properly to minimize environmental impact.
● The high cost of refining rice bran oil due to its complexity can impact the profitability of producing rice bran oil.
● During refining, some of the beneficial compounds present in rice bran oil, such as oryzanol and tocopherols, may be reduced or removed. Balancing the removal of unwanted substances while retaining beneficial components is a challenge.

Our Solutions:
● Enzymatic Deep Degumming Technology
● Maximize Oryzanol Retention
● Optimized Process Scheme and Equipment Configuration
● Cryogenic Vacuum and Energy-saving Deodorization Technology
