Optimisation of minimal processing variables to preserve the functional quality and colour of carrot juice by means of the response surface methodology
Combined processes based on acidification (pH: 4.5, 5.0, 5.5) and mild thermal treatments (T: 56, 58, 60°C) at different exposure times (t: 2, 4, 6 min) were optimised using the response surface methodology to improve the functional quality of carrot juice. The effects on α- and β-carotenes, total a...
