Example 1, (1) Effect of the amount of Soy protein isolate added on the texture of meat balls
As can be seen from FIGS. 2 to 5, the addition of 0 to 1% of the isolated soy protein did not significantly affect the hardness, elasticity, cohesiveness and chewiness of the meat balls (P > 0.05); when the addition amount of the soybean protein isolate is 1-2%, the influence on the chewiness and hardness of the pork ball is significant (P <0.05), and the influence on the elasticity and cohesiveness is not significant (P > 0.05); when the addition amount of the soybean protein isolate is 2-4%, the hardness and the chewiness are remarkably reduced (P is less than 0.05), and the conglomeration of the meat balls is not obviously influenced; in conclusion, the hardness and the chewiness are optimal when the content is 2.0 percent, the elasticity and the cohesiveness are optimal when the content is 3.0 percent, and the addition amount of the soybean protein isolate is 2-3 percent as the optimal amount;
(2) influence of soybean protein isolate addition on meat ball sensory product score and color difference

Tab 4 Effects of soy srotein isolate on sensory score of meatballs
Figure RE-GDA0002414564370000101
Note: different letters a-b indicate the significance of the difference (P <0.05) for different addition levels in the same column.
TABLE 5 Effect of Soy protein isolate addition on meat color difference
Table 5 Effects of soy protein isolate amount on color difference of meatballs
Figure RE-GDA0002414564370000102
Note: different letters a-b indicate the significance of the difference (P <0.05) for different addition levels in the same column.
As shown in Table 4, when the addition amount of the soy protein isolate is 0-3%, the sensory score is increased and then reduced, and the influence is remarkable (P is less than 0.05); when the adding amount is 2%, the sensory score is optimal; because the soybean protein isolate has the functional characteristics of water retention, oil retention, gel and the like, the texture of the meatballs can be greatly improved by adding the soybean protein isolate. However, the soybean protein isolate needs to be added in a proper amount, and each index is obviously reduced when the soybean protein isolate is added too much. As can be seen from table 5, the amount of soy protein isolate added had a significant effect on L of the meatballs, increasing first and decreasing later (P < 0.05); the effect on a and b of the meat balls is not obvious (P > 0.05); the influence of the addition amount of the isolated soy protein on the texture of the meat balls is comprehensively considered, and when the addition amount is 2%, the sensory score is highest and the texture characteristic is relatively good. Therefore, the addition amount of the soybean protein isolate of 2.0 percent is selected as the optimum addition amount for producing the meat balls.
Example 2, (1) Effect of calcium chloride substitution ratio on quality of meat balls
As can be seen from fig. 6, when the calcium chloride substitution ratio is 5-10%, the effect on the hardness of the meat balls is significant (P <0.05), and as the calcium chloride substitution ratio is gradually increased, fig. 7 and 9 show that the calcium chloride substitution ratio of 5-10% has a significant effect (P <0.05) on the elasticity and chewiness of the meat balls, but has no significant effect (P >0.05) on the cohesiveness; when the substitution ratio is continuously increased to 10-15%, the various texture indexes of the meat balls are remarkably reduced (P < 0.05); when the calcium chloride substitution ratio is 10%, the quality of the meatballs can be remarkably improved (P is less than 0.05); with the increase of the calcium chloride substitution ratio, the hardness, the cohesiveness and the chewiness of the meat ball tend to rise first and then fall, the elasticity tends to fall first and then rise and then fall, and each texture index of the meat ball is excellent when the calcium chloride substitution ratio is 10%. Moreover, the taste of the meat balls is affected by adding too much calcium chloride, so that the calcium chloride substitution ratio is most suitable to be 10%.
(2) Influence of calcium chloride substitution ratio on sensory score and color difference of meat ball

Tab 6 Effects of calcium chloride replacement ratio on sensory score of meatballs
Figure RE-GDA0002414564370000121
Note: different letters a-b indicate the significance of the difference (P <0.05) for different addition levels in the same column.
Table 7 effect of calcium chloride substitution ratio on meat pellet color difference
Tab 7 Effects of calcium chloride replacement on color difference of meatballs
Figure RE-GDA0002414564370000122
Note: different letters a-b represent the significance of the difference of different addition levels in the same column (P <0.05)
As shown in table 6, the calcium chloride substitution ratio has a statistical significance (P <0.05) on the sensory score of the pork meatballs, and as shown by the overall sensory effect, the addition of low-level calcium chloride has little sensory effect, and only high-level calcium chloride has a significant effect, but the sensory quality is significantly reduced due to excessive substitution, so that the suitable calcium chloride substitution level is controlled within 10% from the perspective of the sensory quality acceptability. As can be seen from table 7, the replacement ratio of 0-10% calcium chloride gradually increased in significance (P <0.05) to the value of the brightness L of the meat balls, and the replacement ratio of 10-15% potassium chloride had no significant effect on the value of the brightness L of the meat balls; calcium chloride substitution had no significant effect on the redness a and b values of the meatballs (P > 0.05); therefore, the calcium chloride substitution ratio has little influence on the color difference of the meatballs. Considering the texture characteristics, color difference and sensory score, 10% of calcium chloride is selected as the optimal substitution ratio.
Example 3, (1) influence of Chuzhou chrysanthemum leaf addition amount on meat ball quality
As can be seen from FIGS. 10 and 13, the addition of 0-2.5% of Chuzhou chrysanthemum leaves significantly affects the hardness and chewiness of the meatballs (P <0.05), and the effects of elasticity and cohesiveness are not significant (P > 0.05); when the addition amount is 1-1.5%, the hardness of the meat balls is remarkably enhanced (P <0.05), and the chewiness of the meat balls is remarkably reduced (P < 0.05); and the chewiness of the chrysanthemum is reduced sharply when the addition amount of the chrysanthemum leaves is 1.5-2%. With the increasing of the addition amount of the Chuzhou chrysanthemum leaves, particles become 'fillers' of a protein network structure, the compactness of an internal structure is continuously enhanced, and therefore the hardness is increased. However, the Chuzhou chrysanthemum leaf particles cannot be crosslinked with the protein and fat themselves, but the crosslinking between the protein and the fat is hindered to some extent, so that the elasticity is not significantly changed. When the amount of the Chuzhou chrysanthemum leaves is increased to a certain degree, the particles can hinder the formation of a protein network structure, reduce the crosslinking of protein and fat, loosen a gel network structure and further reduce the hardness.
(2) Influence of Chuzhou chrysanthemum leaf addition amount on meat ball sensory score and color difference

Note: different letters a-b indicate the significance of the difference (P <0.05) for different addition levels in the same column.

Tab 9 Effects of the addition of Chrysanthemum morifolium ramats on the color and peroxide value(POV)of
meatballs
Figure RE-GDA0002414564370000132
Note: different letters a-b indicate the significance of the difference (P <0.05) for different addition levels in the same column.
The sensory score of the Chuzhou chrysanthemum leaves on the pork ball is increased and then decreased, and the sensory score is highest when the addition amount of the Chuzhou chrysanthemum leaves is 1.5%; as can be seen from table 9, the addition amount of the chuzhou chrysanthemum leaves significantly affected the L value of the meat balls (P <0.05), the brightness of the meat balls gradually decreased with the addition amount of the chuzhou chrysanthemum leaves, the brightness was optimal at an addition amount of 1.5%, and the yellowish green degree leaves significantly changed with the increase of the chuzhou chrysanthemum leaves. As the Chuzhou chrysanthemum leaves are rich in chlorophyll and other fat-soluble pigments, the Chuzhou chrysanthemum leaves can be combined with fat to influence the brightness of the fat, so that the L value of the meat balls is reduced; the Chuzhou chrysanthemum leaves are yellow green originally, and the rich lutein is highly colored, so that the a value of the meat balls is reduced along with the increasing of the Chuzhou chrysanthemum leaves. Unsaturated fatty acid in the meat balls can react with oxygen in the air, oil in the meat balls is oxidized to generate hydrogen peroxide and decomposed to generate aldehyde, ketone, lower fatty acid and the like, so that the quality and the nutritional ingredients of the meat balls are reduced, the rancidity degree of the oil can be known through measuring the content of the peroxide, and the rancidity speed of the oil can be relieved through the oxidation resistance in the chrysanthemum leaves obtained through measuring results. Comprehensively considering, the optimal addition amount of Chuzhou chrysanthemum leaves is 1.5%.
Example 4, (1) Effect of pig fat addition on the texture of meat pellets
As can be seen from fig. 14, the hardness of the meat balls can be significantly increased by 10-30% of the fat content (P <0.05), and the hardness of the meat balls can be significantly decreased by more than 30% of the fat content (P < 0.05); from fig. 15, it can be seen that the elasticity of the meat balls can be significantly reduced by the addition of fat above 20%, and the overall effect is not significant (P < 0.05); according to the analysis of the graph 16, when the fat content is 10-20% and 40-50%, the cohesiveness of the meat balls is general, and when the fat content is 20-40%, the cohesiveness of the meat balls is changed remarkably, and the meat balls rise first and then fall (P is less than 0.05); as can be seen from fig. 17, when the fat content was 10 to 30%, the chewiness of the meat balls was significantly reduced, and when the fat content was 30 to 50%, the chewiness of the meat balls tended to increase first and then decrease (P < 0.05). Because excessive fat will increase the prevalence of some diseases and is not good for human health, 20-30% fat is most suitable according to texture characteristics.
(2) Influence of pig fat addition on sensory evaluation and color difference of meat balls
TABLE 10 Effect of pig fat addition on sensory score
Tab 10 Effects of pig manure addition on sensory score
Figure RE-GDA0002414564370000151
Note: different letters a-b indicate the significance of the difference (P <0.05) for different addition levels in the same column.
TABLE 11 influence of pig fat content on the color difference of meat balls
Tab 11 Effects of fat additions on color of porkballs
Figure RE-GDA0002414564370000152
Note: different letters a-b indicate the significance of the difference (P <0.05) for different addition levels in the same column.
As can be seen from table 10, there was a significant difference in the effect of lean body mass on the sensory score of the pork meatballs (P < 0.05). In the range of the experimental proportion, the sensory score is increased and then reduced, and the sensory score is the highest when the pig fat adding amount is 30 percent; as can be seen from fig. 14 and 17, the hardness and the chewiness were optimized at the pig fat content of 10%, both of which showed a downward trend (P <0.05) with the increase of the fat content ratio, the elasticity was optimized at the pig fat content of 20%, and the cohesiveness was optimized at the pig fat content of 30%. Lean pork and fat pork are the basis of the meat balls, the influence of the addition amount of the fat pork on each index of the meat balls is large, when the addition amount of the fat pork exceeds 30%, the fat content is increased to generate greasy feeling, and the color, the taste, the elasticity, the tissue state and the like are gradually reduced. As can be seen from table 11, the significant increase in the meat ball brightness L (P <0.05) was gradually achieved by the addition of 10-30% fat; the addition amount of the fat is 10-50%, so that the influence of a value of the meat balls is obvious (P is less than 0.05); the significance of the b value of the meat ball is gradually increased by adding 10-500% of fat (P < 0.05). The reason is that under the condition that the contents of other main materials are not changed along with the increase of the fat content, the influence of the Chuzhou chrysanthemum on the brightness of the meat balls is reduced, the L value of the meat balls is increased, the a value and the b value are reduced and comprehensively considered, and the pig fat content of 30% is selected as the optimum content for producing the meat balls.

Tab 12 Orthogonal test plan and test results
Figure RE-GDA0002414564370000161
Direct analysis
The test investigation index is that the larger the composite score is, the better, and as is directly seen from table 12, the test result (composite score) of the combination condition A2C2D2B2 of test No. 5 is the largest, and the highest value among the 9 tests is.
Computational analysis
As can be seen from table 12, through analysis of an orthogonal experiment L9(34), the size of the factors affecting the quality of the meat balls is, in order, the addition amount of the isolated soy protein > the addition amount of the chrysanthemum leaves > the addition amount of the pig fat > the calcium chloride substitution ratio, and the optimal process parameter set is A2C2D2B2, that is, 2.0% of the isolated soy protein, 10% of the calcium chloride substitution ratio, 1.5% of the chrysanthemum leaves, and 30% of the pig fat.
TABLE 13 results of ANOVA
Tab 13 Results of variance analysis.
Figure RE-GDA0002414564370000171
As can be seen from table 13, the addition amount of the isolated soy protein and the addition amount of the chuzhou chrysanthemum leaves have significant effects on the quality of the meatballs (F ratio > F0.05), wherein the effect of the isolated soy protein is the largest, and the final cooling temperature has no significant effect on the spiced beef (F ratio < F0.05).
The optimal experimental results obtained by direct analysis and computational analysis are different, further verification experiments need to be carried out, and the verification experiments show that the quality of the conditional combination A3B1C1 spiced beef is superior to that of the conditional combination A2C2D3B2, so the optimal experimental conditions obtained by the research are as follows: the addition amount of the isolated soybean protein is 2%, the calcium chloride substitution ratio is 10%, the addition amount of the Chuzhou chrysanthemum leaves is 1.5%, and the addition amount of the pig fat is 30%.
(2) Shelf life test of meatballs
Determination of product shelf life [17] samples were tested at 35 ℃ and 25 ℃ for texture, color difference, moisture, microorganisms and sensory follow-up, wherein no microorganisms were detected and there was no significant change in texture, color difference and moisture, thus quality of the product was evaluated primarily by sensory evaluation.
