For this reason, we chose to study beta-cryptoxanthin more extensively. Methods and Results : From the result of clinical trial using beta-cryptoxanthin-enriched Mandarin orange juice, it was proven to potentiate the preventive activity of multi-carotenoid mixture against liver cancer in the patients with chronic viral hepatitis-induced liver cirrhosis. Furthermore, beta-cryptoxanthin also has preventive activity against alcohol-induced gamma-GTP elevation, and obesity. Conclusion : An antioxidant beta -cryptoxanthin seems to be valuable for health promotion.
