VILLA RAMIREZ, Rigoberto; SANCHEZ ANTE, Tatiana  e  ARBELAEZ ARIAS, Lina. EFFECTS OF POLLEN CONCENTRATION IN THE RHELOGICAL, COLORIMETRIC, PHYSICAL AND CHEMICAL PROPERTIES OF ORANGE JUICE. Investig. andina [online]. 2019, vol.21, n.39, pp.185-194.  Epub 01-Fev-2021. ISSN 0124-8146.

Taking into account the benefits of drinking orange juice and pollen, we decided to propose a research to standardize a type of orange juice enriched with pollen. Thus, we made two kinds of juice with different concentrations of pollen: P1% and P5%. We evaluated its color coordinates (L*, a* y b*), its rheological behavior and its physical and chemical characteristics. Colorimetric criterion L*, a* y b* of the CIELab system for the color of commercial juice, in comparison to the enriched juice with pollen, increased for the L* and a* values, given the bigger contribution to luminosity and red color that brings the pollen. Rheological behavior showed a Newtonian behavior for the juice with 1% concentration, becoming a non-Newtonian liquid after the concentration. Physical and chemical analysis, through measurements of Brix, pH and titrateable acidity ratios, allows to conclude that the analyzed treatments comply with the specifications of the 5468 Colombian Technical Norm (NTC in Spanish): juice, pulp, fruit nectar and its concentrates.
