The yellowish pink pool of chicken is the deciding factor affecting customer buying behavior.In processing and storage, chicken meat, through constantly oxidation stain, by initial de-oxygenated myoglobin (deoMb), oxymyoglobin (oxyMb), is transformed into unwelcome sepia derivative.As can be seen from table 3, table 4; chicken meat metmyoglobin content and value of chromatism a* present certain negative correlation; compared with other two kinds of defreezing methods; the oxidation of chicken meat myoglobins more effectively can be suppressed when dynamically thawing; slow down brown stain speed; protect the color and luster of meat, extend the quality retention time of meat.
The change of chicken TVBN content under table 5, three kinds of defreezing methods
VBN (TVBN) reflects the change of fishery product protein, is one of primary chemical index judging chicken freshness.Due to the effect of microorganism and enzyme, breaks down proteins in decay process and produce the alkaline nitrogen substances such as there is volatile ammonia and amine, and the content of such material is higher, show that amino acid is decomposed more, the degree that chicken goes bad is larger, therefore, its freshness of the higher expression of TVBN value is poorer.As can be seen from Table 5, under three kinds of thawing modes, although TVBN value has certain growth, the TVBN that dynamically thaws increases minimum, and after that is thawing, the freshness of chicken is best.
The change of chicken meat histamine content under table 6, three kinds of defreezing methods
Histamine is the important indicator weighing chicken freshness.Compared with conventional method TVB-N, TMA-N, histamine more can reflect quality and the safe condition of chicken exactly
].Histamine Producing reason is closely related with the decay process of chicken, and chicken body is after death under bacterial action, and histidine will decompose rapidly generation histamine
].Dynamically defreezing method histamine content recruitment is minimum as can be seen from Table 6.
The change of chicken meat total plate count under table 7, three kinds of defreezing methods
The activity of microorganism is the principal element affecting chicken shelf life.Microbial growth breeding will decompose protein and generation Ammonia material in chicken, and cause pH to raise, affect the stability of myoglobins in chicken, and then affect the color and luster of golden rifle chicken chicken, therefore the quantity of microorganism is the important indicator affecting color and luster
].Dynamic resolution frozen meat total plate count is minimum as can be seen from Table 7, and after that is thawing, chicken is best in quality.
