Chicken is appreciated by consumers because it is a very versatile meat, affordable, and generally recognized as healthier and more environmentally friendly than red meats. Currently, chicken cuts are mostly sold packaged; thus, the adequate establishment of shelf life is fundamental. Our aim was to evaluate the potential of using an online consumer test to determine the freshness of chicken breast and the extension of shelf life based on viewing photographs. The results showed that the use of images of chicken breasts, vacuum packed, and modified atmosphere packaged (MAP), for an online consumer test is an interesting strategy. The results are consistent with those obtained from a group of consumers performing the test live with images and odor evaluation and with the counts of spoilage microorganisms. The relationship between microbial counts and acceptability was unclear, particularly in the MAP samples, which presented counts considered acceptable but were rejected by the consumers.

使用摄影对鸡胸肉的新鲜度和保质期进行在线消费者测试

鸡肉受到消费者的赞赏，因为它是一种用途广泛的肉，价格合理，并且比红肉更健康，更环保。目前，鸡肉切块大多以包装出售。因此，充分建立保质期至关重要。我们的目的是评估使用在线消费者测试来确定鸡胸肉的新鲜度以及根据观看照片来延长保质期的潜力。结果表明，使用鸡胸图像，真空包装和气调包装（MAP）进行在线消费者测试是一种有趣的策略。结果与从一组进行图像和气味评估的现场测试的消费者获得的结果以及腐败微生物的数量一致。
