The Effect of Different Gums to the Recoverable Carotenoid Content, Moisture Content, and Color of Co-Crystallized Red Fruit Oil (Pandanus conoideus Lam.) over Storage Period

---

Red fruit (Pandanus conoideus Lam.) is characterized by red coloration, due to its high amounts of
carotenoid, an ideal source for natural food colorants. However, carotenoids are prone to degradation
during processing. Co-crystallization is used to improve the applicability and stability of these pigments.
Carotenoid content analysis was done to see the effect of processing on the recoverable carotenoid
content (RCC) of RFO. The statistical analysis showed that there is no significant difference in carotenoid
content between pure and co-crystallized RFO samples (???? = 0.719). Gum stabilizers were added to
improve encapsulation and preserve the RCC over time. Storage analysis is done for 3 weeks to see
change in RCC, moisture content, and color over time. While the RCC of the samples decreased over
time, it was deemed statistically insignificant, with the exception of gum Arabic sample after 3 weeks of
storage (???? = 0.042). Moisture content analysis indicated no significant differences between all samples
at week 0, 1, and 3 (???? = 0.157, ???? = 0.193, ???? = 0.084), but significant difference at week 2 (???? = 0.033)
between the control and samples with NaCas. Color analysis was performed on the samples using image
analysis, and show that there is a statistically significant difference of color values in samples formulated
with NaCas and those without (L*, ???? = 0.022; a*, ???? = 0.041; b*, ???? = 0.020). This shows that the addition
of NaCas resulted in a lighter color.
