摘　　要：番茄红素是一种天然色素和抗氧化剂,含有多个共轭双键,具有多种有益的生物活性。本研究采用高压均质的方法,分别以油茶皂素和吐温80为乳化剂制备了2种不同的番茄红素乳液。研究了不同乳化剂对乳液储藏过程中物理稳定性、番茄红素保留率以及油脂氧化的影响。结果表明,储存28 d后乳液的ζ-电位虽然显著降低但仍保持在30 mV以上。在50℃储存14 d后,吐温80稳定的乳液的POV值从初始的4.30 mmol/kg增加到8.98 mmol/kg,而CS乳液仅增加了1.70 mmol/kg。油茶皂素作为乳化剂能有效改善乳液在储存过程中的氧化稳定性,延缓油脂氧化的进程,降低氧化产物的生成。Lycopene is a natural pigment and antioxidant that contains several conjugated double bonds and has several beneficial biological activities.In this study,two different lycopene emulsions were prepared by high-pressure homogenization using camellia saponin and Tween 80 as emulsifiers.The effects of different emulsifiers on the physical stability,retention rate and lipid oxidation of the emulsions during storage were investigated.The results demonstrated that theζ-potential of the emulsions remained above 30 mV even after 28 days of storage,albeit with a significant decrease.Following a storage period of 14 days at 50℃,the POV value of the Tween 80-stabilised emulsion escalated from its initial level of 4.30 mmol/kg to an elevated level of 8.98 mmol/kg,whereas that of the CS emulsion only experienced a marginal increase by 1.70 mmol/kg.It was shown that as an emulsifier,camellia saponin can effectively improve the oxidative stability of the emulsions during storage,slowing down the process of lipid oxidation and reducing the production of oxidation products.
