Quality Indicators of Northern Shrimp (Pandalus borealis)

Qingzhu3.13 Data analysisThe data, including instrumental texture parameters, sensory score and water-holdingcapacity value, was tested using analysis of variance (ANOVA) to analyze if a differenceexisted within a group and among groups during the storage time, and to show theDuncan’s Multiple-Comparison Test. Linear equation and the correlation coefficients (R)of some indicators such as total volatile bases nitrogen (TVB-N), trimethylamine (TMA),total viable counts (TVC), water content, salt content and electronic nose measurementparameters were calculated. Principal component analysis (PCA), which was conductedin the statistical program Unscrambler (Version 7.5, CAMO ASA, Oslo, Norway), wasperformed to study the main tendencies of the variation among the measurement variableand to evaluate if the various analytical techniques applied were comparable to evaluatequality. In all cases, significance levels were set at 95% (P
