Abstract:

Evaluation of fruit juice quality is an important parameter in terms of consumer acceptability and international conformity standards. The objectives of this study were to evaluate the quality and sensory attributes of orange, mango, and apple juice brands consumed in Oman and to observe whether they meet the standard of compliance status and consumer satisfaction. Samples from five brands of different fruit juice products (15 samples in total) were collected to investigate the physicochemical characteristics, sensory attributes, consumer preferences, and compliance with label standards. The brands were labelled as (D, E, F, L, and J for orange juices; N, B, I, H, and O for mango juices; and M, C, K, A, and G for apple juices). Results revealed that noncompliance of Brix values in juices were as follows: mango juice brand B, 11.6 and brand O, 11.8; and apple juices brand M, 11.2 and brand K, 10.8. The overall acceptability scores for sensory assessment ranged from 2.3 to 3.7 for orange juices, 1.5 to 4.3 for mango juices, and 1.3 to 3.8 for apple juices, while average consumer preference scores ranged from 2.2 to 3.6 for orange juices, 2.5 to 3.7 for mango juices, and 2.4 to 3.4 for apple juices. All evaluated juice brands were found to be non-compliant (NC) with label requirements. This study may assist in improving and implementing legislation of fruit juice products, thereby contributing to the maintenance of a sustainable fruit juice industry through enhanced quality control.
