Abstract

Objectives　We investigated the effects of feeding Satsuma mandarin juice containing high content of β-cryptoxanthin for 8 weeks on visceral fat area in healthy volunteers. Methods　We conducted a randomized, double-blind, parallel-group comparative study. Subjects whose BMI was 23-30 were divided into the two groups: one receiving concentrated β-cryptoxanthin︱rich juice（β-cryptoxanthin 4.0 mg per 200 mL╱day）and another receiving concentrated β-cryptoxanthin-non-rich juice （β-cryptoxanthin 1.6 mg per 200 mL╱day）for 8 weeks. Results　The β-cryptoxanthin-rich juice induced the significant reduction of the visceral fat area after 5 weeks and 8 weeks compared to the start of the feeding. Moreover, the visceral fat area in the β-cryptoxanthin-rich juice group were significantly lower than that in the β-cryptoxanthin-non-rich juice group.Conclusions　These result suggested that β-cryptoxanthin-rich Satsuma mandarin juice has the effect to reduce visceral fat area.
