Abstract:
Color is a major indicator of quality of frozen litchi pulp and frozen litchi pulp browning during frozen storage may affect the value of the goods. By colorimeter measurement, it was found that when strored below -60 ℃, no color change occured.Samples frozen at -18 ℃ showed a slight color change .Analysis of browning intermediates 5-(hydroxymethyl) furfural indicate that 5 - (hydroxymethyl) furfural in frozen litchi pulp at -60 ℃ unchanged,but slightly decreased when the samples was frozen at -18 ℃. During storage at -18 ℃ and at -60 ℃, no changes were found in nutrition chemicals content except for reducing sugar at -18 ℃.
