Study on Lycopene Microcapsule Prepared by Antioxidation Wall Materials

Abstract:

The manuscript investigated the preparation method of lycopene microcapsule by homogenization and spray-drying technique using Maillard reaction products（MRPs） of whey protein isolate（WPI） and xyloligosaccharides as novel antioxidation wall material system. The optimum experimental parameters were as follows：the mass ratio of xyloligosaccharides to WPI 1∶2，heating time 3 h，pH 10，homogenization pressure 40 MPa. The yield and encapsulation efficiency of microencapsulated lycopene were 86.28% and 94.11%，respectively. Moreover，through analyzing of retention rate，the results indicated that wall materials could protect lycopene from oxidation，and thus improve the storage stability of lycopene.
