In order to construct the texture of the ham standard reasonable compression ratio of the critical factors determining the textural properties of the ham, using the the mandatory definitions and indirectly reflect the texture characteristics develop suitable products texture of minced meat class sensory evaluation standard, and so Textural indicators for basic research instead of sensory score ham level to verify the feasibility of the application of the discrimination aspect, the the sensory score points corresponding to the reference sample texture value, to establish a standard range of hardness, brittleness and adhesion, through the establishment of the sensory score as independent variables, the texture value of the dependent variable linear regression equation to obtain flexibility, cohesiveness and chewiness standard range, and finally to the texture based on the value of the different brands of ham Fisher linear discriminant equation . The study results show that: (1) the brittle indicators detected or not determine the compression ratio of the reference; the ham products gel system reaches a certain strength, compression ratio consistent; (2) hardness, brittleness, adhesion, elasticity, chewiness and cohesiveness of sensory score and texture values ??the coefficients were 0.981,0.990,0.938,0.855,0.835 and 0.534 (P lt; 0.01), discriminant correct grade of ham as 100%. Sensory evaluation standards established well distinguish the texture of minced meat products category; ham sensory score (3) the use of textural properties and texture data to establish the level canonical discriminant function discriminant correct level of ham 92.2% and 100.0%, respectively, can distinguish the level of the ham, but the latter is more convenient maneuverability, higher accuracy ratings textural properties of sensory and texture values; (4) in the specific test conditions premium ham hardness, brittleness, adhesion, elasticity, cohesiveness and chewiness values ??were: 8690.162 ~ 9357.137g, 8929.995 ~ 10963.274g, -102.467 ~-45.155g, 0.813 ~ 0.968,0.200 ~ 0.279 and 1597.786 ~ 2331.163g; superior grade ham hardness, brittleness, adhesion, elasticity, cohesiveness and chewiness values ??were: 7441.334 ~ 9188.984g, 6700.973 ~ 8929.995g, -102.467 ~-66.644g, 0.741 ~ 0.878, 0.174 to 0.247 and 1348.957 ~ 2021.951g;, General class ham hardness, brittleness, adhesion, elasticity, cohesiveness and chewiness values ??were: 6714.754 ~ 8690.162g, 4441.556 ~ 6700.973g, -257.264 ~-159.397g, 0.633 ~ 0.743,0.122 ~ 0.183 and 602.470 ~ 1093.673g;, the Fisher linear discriminant equation: super (Y4) = 0.066 X7 0.026 X8-1.316X9 2062.795 X10 3933.459 X11-0.588 X12-1270.152-prime (Y5) = 0.069 X7-0.023X8-1.285 X9 2062.224 X10 4050.930 X11-0.603X12-1268.820 ordinary level (Y6) = 0.074 X7 0.023 X8 1.368 X9 2025.211 X10 4001.763 X11 0.617 X12-1274.327-style-X7, X8, X9, X10, X11 and X12 represent hardness, brittleness, adhesion, elasticity, cohesiveness and chewiness values. The method of discriminating the level of the sample is: and the unknown sample the texture index values ??are substituted into the above discriminant equation to calculate the function values, the obtained value of the largest level of representation is the unknown sample's level. The use of discriminant function discriminant ham Level a higher accuracy. Ham created range of textural standard and Fisher linear discriminant equation can be applied to the development of such products and quality evaluation.
