Influência da embalagem e estocagem no conteúdo de beta-caroteno e ácido ascórbico em suco de manga “Ubá” industrializado

Abstract

This work investigated the content and stability of two natural antioxidants - β-carotene and ascorbic acid (AA) - in mango juice industrialized and stored during different storage times, correlating the recommendations of vitamins A and C with the content found in the juice. β-carotene and AA were analyzed in juice sold in tetra pak packaging, during five storage times (1 to 5 months) and in glass containers, during three storage times (after 3, 4 and 5 months of storage). The analysis was carried out using High Performance Liquid Chromatography (HPLC). No statically differences (α = 5%) were found between the different times of storage for both compounds analyzed, both in tetra pak package and glass container. Furthermore, no significant differences were found between the β-carotene content of the juices sold in both containers. However, we found statistical differences in AA levels between the different packages, with glass containers showing greater content compared to tetra pak packaging. Thus, losses occasioned by package permeability to oxygen should be subject of concern in the food industry.
