b*Mode evaluate color variation.
From figure 7 it can be seen that with the drying and ripening of sausage, a of each group*/b*Value is before fermentation phase and maturity period, mid-term
It is in rising trend, this may be because of ferment sausage dehydration within this time, to improve the concentration of myoglobins, this meeting
Improve a*Value, meanwhile, or sodium nitrite is converted into NO under the action of the microbial enzyme of part, is formed in conjunction with myoglobins
Cherry nitrosomyoglobin, so that a*It increases.In the mature later period, sausage contained humidity is fewer and fewer, and coloring matter is dense
Contracting, so that a*Rising slows down or declines.It can be obtained by Fig. 7, add Testa Tritici extract group when sausage maturation is 26 days
a*/b*Value will be significantly higher than control group (p < 0.05), it may be possible to since Testa Tritici extract bacteriostasis inhibits the life of spoilage organisms
It is long, it is more conducive to the conversion that lactic acid bacteria etc. accelerates nitrous myoglobins as dominant microflora.
4 salami sensory evaluation of embodiment analysis
18 people (9 male 9 female) that choosing has Majors of Food background carry out sensory evaluation.Respectively by color, color homogeneity, at
Ripe fragrance, tart flavour, mouthfeel and whole preference degree are evaluated, 5 points of evaluation methods processed, sensory evaluation marking table such as 1 institute of table
Show, evaluation personnel can also beat score in two score sections.Respectively from color and uniformity, fragrance, tart flavour, coherency with
And sensory evaluation has been carried out in terms of whole preference degree, the analysis of front can be seen that different leavenings influences not the property of sausage
One.
1 sensory evaluation of table marking table
The whole preference degree of comprehensive color, uniformity, fragrance, tart flavour and coherency five indices to different grouping salami
Sensory evaluation is carried out, as a result as shown in Figure 8.The salami entirety preference degree for adding 27g/kg Testa Tritici extract is significantly high
In control group (p < 0.05).
