Multiple linear regression modelling of hot water extraction of soursop juice

The effect of hot water extraction on juice yield, ascorbic acid, lightness and total soluble solids of soursop juice was modelled using the response surface methodology. The soursop samples were treated at extraction temperatures of 30, 60 or 90 °C for extraction times of 30, 90 or 150 minutes. The...
