Study on the sensory acceptance and check all that apply of mixed juices in distinct Brazilian regions

Abstract Fruit juices are on the rise, due to the search new mixes, flavors and nutritional value. This research investigated the acceptance and sensory profile of mixed juices. Sixteen (16) mixed juices with caja, umbu, cocoa and mango flavors were studied, using acceptance and check-all-that-apply (CATA) tests in different cities (n = 226). Juices A1 and D1 had the highest scores in Porto Alegre-RS, Brazil (respectively, 7.15 and 6.91). Differently from Salvador-BA, Brazil, where the highest scores were D2 (6.76) and D3 (6.71). Using CATA, it was shown that customers in the Southern Region characterized samples differently from customers in the Northeastern Region, and the correspondence analysis, showed that consumers in Porto Alegre-RS presented different attributes than those in Salvador-BA, with respect to mixed juices and their acceptance. It is suggested the validity of the consumer data in the characterization of the sensory parameters of the mixed juices and that the familiarity with the fruit flavors interfered in the acceptance of the same.

摘要 随着消费者对新型混合配方、风味及营养价值的追求日益高涨，果汁产品市场持续升温。本研究针对混合果汁的消费者接受度与感官特征展开探究。研究共选取16款添加卡雅果（caja）、翁布果（umbu）、可可与芒果风味的混合果汁，在巴西两座不同城市采用接受度测试与逐项勾选法（check-all-that-apply, CATA）开展感官评价，共纳入226名受试者。在巴西南里奥格兰德州阿雷格里港，A1与D1两款果汁得分最高，分别为7.15与6.91；而在巴西巴伊亚州萨尔瓦多，得分最高的则为D2（6.76）与D3（6.71）。通过逐项勾选法分析结果可见，巴西南部地区消费者与东北部地区消费者对样品的感官描述存在显著差异；对应分析结果同样表明，针对混合果汁及其接受度，阿雷格里港与萨尔瓦多的消费者所关注的感官属性各不相同。本研究验证了消费者评价数据可有效表征混合果汁的感官参数，同时证实消费者对目标水果风味的熟悉程度会对其接受度产生显著影响。
