抗氧化型壁材包埋番茄红素微胶囊的研究

研究了新型抗氧化性壁材制备番茄红素微胶囊的生产工艺。采用番茄红素为芯材，乳清分离蛋白与低聚木糖的美拉德反应产物（MRPs）为壁材，通过均质和喷雾干燥制得番茄红素微胶囊。优化的工艺参数为乳清分离蛋白与低聚木糖的质量比1∶2，加热时间3 h，pH 10，均质压力40 MPa。在此条件下得到的微胶囊产率和包埋效率分别为86.28%和94.11%。通过保留率的数据分析，结果表明壁材能够有效保护芯材成分，提高番茄红素微胶囊的储存稳定性。
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
