Hylocereus Undatus Fruit Juice

Key findings

1. 01 A clinical investigation involving 26 volunteers revealed that a 1% Hylocereus Undatus fruit extract significantly reduced porphyrin accumulation, indicative of constrained P. acnes growth, alongside improvements in skin radiance and enhanced skin barrier function, as measured by TEWL, compared to a placebo.
2. 02 Another comprehensive study demonstrated that a 1% Hylocereus Undatus fruit extract, when formulated into a gel-cream, achieved a statistically significant reduction in red spot counts by 35% at day 28 and 36% at day 7, underscoring its anti-inflammatory effects. This study also reported a 4% statistically significant improvement in redness and irritation grades at day 28. Furthermore, the extract enhanced skin microbiota diversity, particularly in older individuals, and decreased the presence of pathogenic species such as Corynebacterium tuberculostearicum. Additional benefits included an approximate 30% increase in skin resilience, a 13% reduction in Transepidermal Water Loss (TEWL), an 11% increase in skin radiance (ITA score), and a reduction in visible signs of aging like wrinkles.

Stability

Optimal stability for the active betacyanins, characteristic of red dragon fruit, is observed at a pH of 5.0. Elevated temperatures can detrimentally impact the retention of its nutritional and quality attributes, including color, aroma, and flavor. To bolster betacyanin stability within juice and concentrates, an addition of 0.25% w/w ascorbic acid is recommended.

Synergies

• Ascorbic Acid (for betacyanin stabilization)

Conflicts

• Heat treatments (can degrade quality factors)
