CORTES RODRIGUEZ, MISAEL; GUARDIOLA, LUÍS FERNANDO  e  PACHECO, ROGER. APLICATION OF MATRIX ENGINEERING IN THE FORTIFICATION OF MANGO (VAR. TOMMY ATKINS) WITH CALCIUM. Dyna rev.fac.nac.minas [online]. 2007, vol.74, n.153, pp.19-26. ISSN 0012-7353.

The present investigation analyzes the vacuum impregnation response of mango (var. Tommy Atkins) structure, and shows the Ca⁺² concentration reached at the enrichment product. In order to allow an adequate Ca⁺² incorporation, according to the 20 % Daily Recommended Intake (IDR)/200 g of fresh mango, an impregnation solution was designed with the appropriate amounts of sucrose and CaCl₂. The impregnation parameters are affected by the interaction between Ca⁺² and mango pectic material, whereas, Ca⁺² levels are remarkable higher than the expected enrichment criterion (44% IDR /200 g fresh mango). This phenomenon could be due to Ca⁺² theoretical quantification obtained after and before weights differences in vacuum impregnation process, furthermore the native liquid flows from the fruit structural matrix to the dissolution as a vacuum pulse effect.
