Abstract Melanosis is an important shelf-life limiting factor of both fresh and processed (i.e., cooking and high pressure processing) snow crab (Chionoecetes opilio) clusters, as it gives an unpleasant discolouration. A cluster includes four walking legs, and one claw attached to a shoulder joint. To be able to give a fast and objective measurement of melanosis, a chromatic value using analysis of digital images of high pressure processed clusters (0.1–600 MPa) has been developed and tested against sensory melanosis judgment by three trained assessors. Using L* and b* values from 35% of the pixels in the picture of the clusters gave a chromatic melanosis value with a significant (p

通过数字成像开发用于确定高压加工雪蟹（Chionoecetes opilio）簇黑变病的色度值

摘要 黑变病是新鲜和加工（即烹饪和高压加工）雪蟹（Chionoecetes opilio）簇的重要保质期限制因素，因为它会导致令人不快的变色。一个集群包括四个步行腿和一个连接到肩关节的爪子。为了能够快速客观地测量黑变病，已开发出使用高压处理簇 (0.1-600 MPa) 数字图像分析的色度值，并由三名训练有素的评估员针对感官黑变病判断进行测试。使用来自簇图片中 35% 像素的 L* 和 b* 值给出了显着 (p
