Microencapsulamiento para la obtención de polvo a partir del subproducto de mango (Mangifera indica)

Abstract

In the present investigation, the effects exerted by the inlet temperature (140 ºC, 155 ºC and 170 ºC), the feed pump flow (20%, 30% and 40%) and the concentration of solids (10%, 12.5% and 15%) on the performance of encapsulated powder of mango by-product, phenol content and antioxidant capacity. The highest yield was 71.40% and was obtained by working with the following conditions: 170 ºC of temperature, 12.5% of solids and 20% of flow. For total phenols the results were in a range between 18.1 and 51.2 mg EAG /g encapsulated. The measurement of the antioxidant capacity was carried out by three methods: DPPH, FRAP and ABTS. The results for DPPH were from 8.39 to 44.00 μMET /g encapsulated, for FRAP values of 8.96 to 19.59 μMET /g encapsulated, and finally ABTS with values of 11.73 to 38.97 μMET /g encapsulated the encapsulated particles had a particle size between 0.27 and 8.86 μm, they were agglomerated, spherical and amorphous depending on the atomization conditions. The powders could be used in the industry as functional ingredients.
