Abstract: Cloudy apple juice is rich in nutrition, and shows variety of physiological functions. However, one of the main factors restricting the development of cloudy apple juice is poor storage stability. In this study, some research progress of stabilizing mechanism of cloudy particle components (CPC) in cloudy apple juice was reviewed, included the ingredient of cloudy particle component, aggregation and instability processes of CPC, and the main influencing factors of CPC system stability. In addition, the research directions of CPC stabilizing in cloudy apple juice also been prospected. This study could provide some ideas and references in stabilizing cloudy apple juice, improving preservation quality, and promote the rapid development of cloudy apple juice industry.
