Example 3: preparation process optimization of tomato fried egg ingredient bag
In this example, based on examples 1-2, the effects of the addition amount of edible oil, the addition amount of water, the frying time and the addition amount of tomato blocks on the performance of the tomato fried eggs are examined, and the formula and process of the tomato fried egg ingredient of the present invention are optimized, and the specific test results are shown in fig. 1-4.
Experiments are carried out under the conditions that the oil temperature is 150 ℃, the water adding amount is 42%, the tomato block adding amount is 15% and the frying time is 8min by taking tomato sauce as a reference, and the influence of different edible oil adding amounts on the tomato fried egg ingredient bag is researched. As can be seen from the data in the attached figure 1, the viscosity and the solid content of the tomato fried egg ingredient bag are both reduced along with the increase of the addition amount of the edible oil, the color and luster brightness index L of the product is gradually reduced along with the increase of the addition amount of the edible oil, the redness index a is gradually increased, and the yellowness index b is gradually increased; the brightness index L of the product is in negative correlation with the addition amount of the edible oil, and the redness index a and the yellowness index b are in positive correlation with the addition amount of the edible oil, so that the lycopene and the addition amount of the edible oil are in obvious positive correlation; the sensory score of the tomato fried egg ingredient bag tends to increase firstly and then decrease along with the increase of the addition amount of the edible oil, and each index of a sample is weighted and scored to obtain the optimal level of the addition amount of the edible oil of 25 percent, so that the next test is carried out by taking the water content of the material of 25 percent as a fixed value.
As can be seen from the data of FIG. 2 showing the influence of the water addition amount on the product performance, the solid content and viscosity of the product decrease with the addition of water, while the viscosity and lycopene activity of the sample show obvious negative correlation with the water addition amount, and as the water addition amount increases, the brightness index L of the color gradually increases, and the redness index a and yellowness index b gradually decrease. The brightness index L of the color of the sample is positively correlated with the addition amount of moisture, and the redness index a and the yellowness index b are negatively correlated with the addition amount of moisture. The sensory score of the product showed a tendency to increase first and then decrease as the amount of moisture added increased, and reached a maximum at 42% moisture added. And carrying out weighting scoring on each index of the sample to obtain the optimal water addition level of 42%, and thus carrying out the next test by taking the water addition level of 42% as a fixed value.
As can be seen from the data of the influence of the stir-frying time on the product performance shown in the attached figure 3, the color difference and the viscosity of the product are increased along with the increase of the stir-frying time, the lycopene activity and the solid content of the product are obviously and negatively correlated, the brightness index L of the color of the finished sauce is gradually reduced along with the increase of the stir-frying time, and the redness index a and the yellowness index b are gradually increased. The lycopene is lost when the frying time is too long, and the sensory score of the product tends to increase and then decrease along with the increase of the frying time. Too long a cooking time can cause the extrudate to develop a scorched flavor, and too much cooking can affect the appearance of the extrudate. And (3) carrying out weighted scoring on each index of the product to obtain the optimal stir-frying time level of 8min, and carrying out the next test by taking the stir-frying time of 8min as a fixed value.
As can be seen from the data of the influence of the addition amount of the tomato blocks in the attached figure 4 on the product performance, the viscosity and the color difference of the sample show a trend of decreasing firstly and then being stable along with the increase of the addition amount of the tomato blocks, the brightness index L of the color gradually decreases along with the increase of the using amount of the tomato blocks, the redness index a gradually increases, and the yellowness index b also gradually increases. The redness index a and the yellowness index b of the product are positively correlated with the addition amount of the tomato blocks, and the redness index a and the addition amount thereof have the maximum correlation. And the lycopene activity and the solid content of the tomato blocks increase with the addition amount of the tomato blocks. The sensory scores of the samples did not change significantly, but had a maximum at 15% addition of the tomato mass. And carrying out weighted scoring on each index of the product to obtain the optimal level of the addition amount of the tomato blocks, wherein the optimal level is 15%.
Example 4: preparation process optimization of tomato fried egg ingredient bag
In this embodiment, on the basis of embodiments 1 to 3, the performance of the superconducting tomato ingredient package of the present invention during storage is monitored, a product shelf life model is constructed, and key indexes are screened and evaluated, so that the tomato fried egg ingredient package is optimized by controlling the key indexes.
(1) Effect of storage at different storage temperatures on product Properties
The change of the solid content in the ingredient bag of the tomato fried egg during the storage process at different temperatures is shown in figure 5, and as can be seen from the data in figure 5, the solid content value of the sample stored at the temperature of 4 ℃,25 ℃ and 37 ℃ in the whole storage process of the product is increased from 73.42 +/-0.0216 to 74.89 +/-0.00471, 75.42 +/-0.04784 and 75.48 +/-0.01247, and the solid content value of the product is increased along with the extension of the storage time in the evaluation period, wherein the solid content value of the product is increased at a lower speed when the product is stored at the temperature of 4 ℃ than that of the other two groups of samples.
Further examining the tomato fried egg ingredient bag stored at different temperatures, the change of the viscosity value of the product with the storage time is shown in figure 6. As can be seen from the data in FIG. 6, the viscosity values generally show a tendency to increase and then decrease, wherein the range of change at the storage temperature of 4 ℃ is smaller than that at the other two temperatures, at which the viscosity rises from 1680 to 1862 and then begins to decrease, and falls to 1812 as a minimum; the viscosity at 25 ℃ storage temperature increased from 1680 to 1886 and then began to drop, minimum 1832; the pH at 37 ℃ storage temperature increased from 1680 to 1834 and then began to drop, a minimum of 1789. The viscosity is usually related to the acceptability of tomato fried egg ingredient bags, the lower viscosity can cause excessive vegetable juice and water to influence the sense during eating, the higher viscosity can cause the vegetable to be too thick, and the proper viscosity can be ideally attached to eggs during eating so as to improve the sense experience of consumers.
The color difference is an important index for evaluating the color change of the tomato fried egg ingredient bag, the numerical value of the color difference is in positive correlation with the browning degree of a sample, ester-soluble and alcohol-soluble pigments such as carotenoid and the like can be well reflected, the color difference of the tomato fried egg ingredient bag stored at different temperatures changes along with the storage time as shown in figure 7, the color difference delta E at the three temperatures is in a linear descending trend, the higher the storage temperature is, the more rapidly the color difference of the tomato fried egg ingredient bag is reduced, and the color difference change degree of a product is the smallest when the storage temperature is 4 ℃. The low-temperature storage is more beneficial to keeping the color stability and quality of the tomato sauce product.
The activity of the lycopene is a marked index of the content of the lycopene in the tomato, and the higher the activity of the lycopene is, the stronger the nutritional performance of the lycopene is. The lycopene activity of the product after storage at different temperatures and with the change of the storage time is shown in figure 8, the product is stored at 4 ℃,25 ℃ and 37 ℃ for 45 days respectively, each group is subjected to 3 groups of tests in parallel, and the lycopene activity of the product is determined to be reduced by 0.17361,0.31173,0.81284 respectively.
Figure 9 shows the changes in organoleptic properties, including appearance, flavor and taste, of the tomato scrambled egg ingredient packages at different storage temperatures. As can be seen from the data in FIG. 9, the three sensory scores of the initial samples were 9.77. + -. 0.08, 9.75. + -. 0.15 and 9.72. + -. 0.34, respectively. The longer the storage time the lower the sensory score at each temperature (p < 0.05), with faster flavor and taste deterioration in the 25 ℃ and 37 ℃ samples. With the increase of the storage time, the tomato fried egg ingredient bag gradually loses the color, the flavor and the taste (p is less than 0.05). However, samples stored at the three temperatures were still acceptable to the panelists on day 45. This indicates that the samples stored at 4 ℃ retained better organoleptic qualities than the samples stored at 25 ℃ and 37 ℃.
The tomato fried egg ingredient bag detects escherichia coli and saccharomycete mould of products in the storage process at different temperatures once every three days until no bacteria are detected at the three temperatures for 45 days, and then the escherichia coli and saccharomycete mould detection is carried out on the tomato fried egg ingredient bag which predicts the last day of the shelf life, and no bacteria are detected. The tomato fried egg ingredient bag is packaged and then pasteurized, so that the biological safety of the tomato fried egg ingredient bag in the shelf life can be well guaranteed, and the tomato fried egg ingredient bag is prevented from being rotted and deteriorated due to escherichia coli and saccharomycete in the shelf life.
(2) Establishment of shelf life model
Through the quality change of the tomato fried egg ingredient bag during storage, the pasteurized tomato fried egg ingredient bag does not grow microorganisms, and the water activity and the oil oxidation in food are the main reasons for reducing the nutritional value of the food. Therefore, the shelf life model of the tomato fried egg ingredient bag is established by taking the water activity and the peroxide value as characteristic indexes. Fitting zero-order and first-order equations of water activities and peroxide values of tomato fried egg ingredient bags at different temperatures by using IBM SPSS statics 25 to obtain a fitting equation and a regression coefficient R 2 And the rate of change constant k, the results are shown in table 1.
As can be seen from the data in Table 1, the regression coefficients of the first order kinetic equation of the water activities of the ingredient packages of the fried eggs with tomatoes at different temperatures are all larger than 0.986 and higher than the R of the zero order kinetic equation 2 The method shows that the first-order kinetic equation has more accuracy in describing the water activity change of the tomato fried egg ingredient bag. R of zero order kinetics equation of peroxide number content 2 Are all larger than 0.956 and are all higher than the first-order kinetic equation, which shows that the zero-order kinetic equation has more accuracy in describing the change of the peroxide value in the tomato fried egg ingredient bag.

The above data were applied to an Arrhenius model and calculated. From table 1, the rates k of change of water activity were 0.007, 0.013 and 0.014, respectively, and the rates k of change of peroxide were 0.012, 0.012 and 0.015, respectively. The activation energy (Ea) can be calculated from the slope of the regression line, K, as shown in FIG. 10 by plotting lnk against the reciprocal 1/T of the storage temperature 0 Can be obtained by the intercept of the regression line.
As can be seen from the data in FIG. 10, the slope of the water activity regression line is-1.8926, so that the Ea value of the tomato fried egg ingredient bag is 15.736kJmol -1 Rate constant k 0 Is 6.697, corresponding to R 2 A value of 0.9429; the slope of the regression line of the peroxide value is-500.95, the Ea value of the tomato fried egg ingredient bag is 4165.098kJmol-1, and the rate constant k 0 Is 0.0708, corresponding to R 2 The value is 0.5766.
