摘　　要：该文研究了柑橘纤维的基础性能以及柑橘纤维在酸性乳饮料中对其稳定性的影响。以持水力、持油性、黏度变化来评估柑橘纤维的基本特性;以弹性模量、LUMiSizer稳定性扫描结果、Turbiscan稳定性测定、粒径分布为指标,结合产品离心沉淀率来确定柑橘纤维对酸性乳饮料稳定性的影响。结果表明,柑橘纤维2号持水持油性能优、假塑性强、酸热等加工耐受性好、悬浮力强;在酸性乳饮料中添加0.1%(质量分数)柑橘纤维,可有效减少酸性乳饮料大颗粒聚集、明显改善产品货架期析水、降低沉淀量,对提高酸性乳饮料稳定性有显著效果。由此可知将柑橘纤维推广应用到有悬浮需求、在加工储运期间易发生沉淀、析水、颗粒聚集等稳定性问题的产品中,或替代传统化学合成类稳定剂打造清洁健康标签,对提升产品档次、提高饮料产品的整体稳定性和产品品质,有非常重要的意义。This article investigates the basic properties of citrus fiber and its impact on stability of acidic milk beverages.Evaluate the basic characteristics of citrus fibers based on their water holding capacity,oil holding capacity,and viscosity changes.The influence of citrus fiber on the stability of acidic milk beverages is determined by using loss modulus,LUMiSizer stability scan results,Turbiscan stability measurement,and particle size distribution as indicators,combined with product centrifugal precipitation rate.The results show that citrus fibers have excellent water and oil holding properties,strong pseudoplasticity,good processing tolerance to acid and heat,and strong suspension force.Adding 0.1%citrus fiber 2 to acidic milk beverage can effectively reduce the aggregation of large particles in acidic milk beverage,significantly reduce product shelf life water separation,reduce sedimentation,and have a significant effect on improving the stability of acidic milk beverage.It can be seen that there is great significance to promote the application of citrus fiber to products which need the suspension force to resolve the problem of stability issues such as sedimentation,water separation,and particle aggregation during processing and storage,or replace traditional chemical synthesis stabilizers with natural ingredients for clean and health labels to improve product grade and the overall stability and quality of beverage.
