High hydrostatic pressure (HHP) processing reduced the GI response of mango pulp when consumed by healthy adults. Present work evaluated the effects of HHP processing on concentrations of mango pulp dietary fiber sub-fractions (AOAC 2011.25 method), pectin methyl esterase (PME) activity, and established links with reduction of GI responses in healthy adults. Processing stability of mango pulp micronutrients (carotenoids, phenolics, ascorbic acid, and antioxidant activity) were also assessed. HHP-processing caused fiber inter-conversions from insoluble to soluble dietary fiber, the latter being significantly higher. Concentrations of non-digestible oligosaccharides and PME activities were also higher in treated pulps. In addition, HHP-processing preserved relevant mango phytonutrients such as carotenoids and phenolic compounds. Micronutrient retention and dietary fiber modifications suggested that HHP-processing improved mango pulp benefits for healthy subjects and potentially for patients with chronic metabolic diseases.
