Abstract
In the fruit juice industry, high pressure (HP) processing has become a commercial success. However, enzymatic browning, cloud loss, and flavor changes during storage remain challenges. The aim of this study is to combine kiwifruit puree and HP pasteurization (600â¯MPa/3â¯min) to stabilize cloudy apple juice during storage at 4â¯Â°C. A wide range of targeted and untargeted quality characteristics was evaluated using a multivariate approach. Due to high ascorbic acid content and high viscosity, kiwifruit puree allowed to prevent enzymatic browning and phase separation of an apple-kiwifruit mixed juice. Besides, no clear changes in organic acids, viscosity, and particle size distribution were detected in mixed juice during storage. Sucrose of apple and mixed juices decreased with glucose and fructose increasing during storage. The volatile changes of both juices behaved similar, mainly esters being degraded. Sensory evaluation demonstrated consumer preferred the aroma of mixed juice compared to apple juice.
