Selecting 10 persons with professional knowledge for food, carrying out sensory evaluation on the quality of the Q elastic cake sample from 5 aspects of appearance shape, color, smell, tissue form and taste, and taking the average value of all the total scores as the result of product evaluation index.

Figure BDA0002418411700000121
2. Texture determination of Q-shell steamed cake
This test adopts texture appearance survey Q bullet cake texture quality. The determination method is slightly modified on the basis of the related literature. The instrument probe was a TA11 universal cylindrical probe (diameter 25.4 mm; length 35.0mm) as determined by TPA mode. The parameters of the TPA test program are set to be 60mm/min before, during and after the test, the time interval between the two tests is 5s, the compression ratio is 50 percent, and the compression force is 0.15N.
During testing, the baked Q round cake is cooled, cut into 1cm squares, horizontally placed on an object stage, and the texture of 5 different parts of the Q round cake is measured. Each specimen was tested in 6 replicates. The data processing adopts a method of using a de-extremum value to calculate an average value.
Design of the experiment
3.1 Single factor test design
The influence of the addition ratio of low gluten powder (5%, 7%, 9%, 11%, 13%), the addition ratio of cocoa powder (1%, 3%, 5%, 7%, 9%), the addition ratio of eggs (44%, 45%, 46%, 47%, 48%) and the addition ratio of sugar (9%, 11%, 13%, 15%, 17%) on the texture quality and sensory evaluation of the peeled cut cakes was examined by using the texture quality and sensory evaluation of the Q-elasticity cut cakes as indexes. And carrying out orthogonal test design according to each group of optimal single-factor results.
3.2 orthogonal experimental design
Based on the single-factor test result, an orthogonal test design principle is adopted, and 4 factors, namely the addition ratio of the soft powder, the addition ratio of the cocoa powder, the addition ratio of the eggs and the addition ratio of the sugar, are respectively represented by A, B, C, D to carry out orthogonal analysis test so as to determine the optimal formula of the Q elastic cake. The experimental design is shown in table 2.

Analysis was performed using EXCEL2003 software to map.
5. Results and analysis
5.1 influence of the addition ratio of the low-gluten flour on texture and sensory quality of the Q elastic steamed cake
Fig. 1-3 show the effect of the addition ratio of soft flour on the texture (hardness, elasticity, chewiness) and sensory quality of Q-puff rice cakes. As can be seen from fig. 1, the hardness of the Q-round cake gradually decreases with the increase of the addition ratio of the soft flour, and when the addition ratio of the soft flour reaches 13%, the hardness of the Q-round cake decreases to 86N, which is decreased by 79.63%, and the decrease range is large; as can be seen from FIG. 2, the addition ratio of the low gluten flour has a great influence on the elasticity of the Q elastic cake, so that the highest value of 85mm is reached when the mixture ratio is 13%. As can be seen from figure 3, when the addition proportion of the low gluten flour reaches 13%, the sensory score is the highest and is 93 minutes, under the condition, the cut cake product has the advantages of regular shape, uniform skin color, obvious tissue layering, crisp skin, pure taste, non-greasy taste, proper sweetness and walnut flavor.
5.2 influence of cocoa powder addition ratio on texture and sensory quality of Q elastic cake
The evaluation results are shown in fig. 4-6 in comparison with the influence of the addition ratio of the cocoa powder on the texture and sensory quality of the Q-puff cake. As can be seen from FIGS. 4-6, the cocoa powder addition rate reached 5%, the cocoa cake had the highest elasticity and the sensory score reached 90 points. When a small amount of cocoa powder is added, the Q-round sliced cake can obtain higher taste score, and the flavor of the Q-round sliced cake is more attractive due to the addition of the cocoa powder.
5.3 influence of the addition ratio of egg on texture and sensory quality of Q-puff cake
As can be seen from fig. 7, 8 and 9, as the adding proportion of the eggs is increased, the hardness and the chewiness of the Q-ball cake are maintained at a stable level, when the adding proportion of the eggs is 46%, the hardness reaches 65N, the hardness is increased rapidly, the chewiness is stable at the moment and reaches 77.8mJ, at the moment, the chewiness of the product reaches a stable level, the processing quality and the finished product quality of the Q-ball cake reach the highest, and the sensory score is higher and reaches 90.75 minutes. The addition ratio of the eggs has obvious influence on the elasticity of the Q elastic cake.
5.4 influence of sugar addition ratio on texture and sensory quality of Q-Tanke
As can be seen from fig. 10-12, the hardness and chewiness of the Q-puff cake tend to decrease with increasing proportion of sugar, the elasticity tends to decrease after increasing, when the proportion of sugar reaches 13%, the hardness is moderate, 65N, the chewiness of the product reaches a stable level, and the sensory score is high, and reaches 87 points. Therefore, the sugar adding proportion can maintain the quality and structure of the product and improve the flavor of the product.
5.5 orthogonal test factors and horizontal design of Q elastic cake formula
Through L (4)3) Orthogonal design table, low gluten powder adding proportion, cocoa powder adding proportion, egg adding proportion and sugar adding proportion 4 factors are subjected to optimization tests on 3 different levels. The orthogonal test factors and the horizontal design of the Q elastic cake are shown in table 2, and the orthogonal test design and the test results of the Q elastic cake are shown in table 3.
Table 3: q elastic cake formula orthogonal test table
Figure BDA0002418411700000151
The above-mentioned single-factor test mainly discusses 4 main single factors affecting the texture quality and sensory score of the Q-puff rice cake. In practice, however, the individual factors are cross-affected. Therefore, in order to make the test more scientific and comprehensive, 3 levels around the optimum addition ratio of each factor were selected, orthogonal tests (see table 3) were designed, evaluation was performed according to the scoring criteria of table 1, and the obtained results were technical indices to determine the optimum formulation of the product. As can be seen from Table 3, the factors affecting the texture quality and sensory score of Q-puff pastry are in turn B>A>D>C. Namely, the addition proportion of the cocoa powder has the greatest influence on the texture quality and sensory score of the Q elastic cake, and the optimal addition proportion is 5%; the addition proportion of the low-gluten flour has a second important influence on the texture quality and sensory score of the Q elastic steamed cake, and the optimal proportion is 13%; the adding proportion of the sugar plays a secondary role in the texture quality and sensory score of the Q elastic steamed cake, and the optimal adding proportion is 13%; the influence of the adding proportion of the eggs on the texture quality and the sensory score of the Q-shaped elastic cake is the least, and the optimal level is 46%. The optimal combination of 4 factors is therefore A3B3C2D2. Therefore, the best process formula for preparing the Q elastic steamed sponge cake comprises the following steps: 13% of low-gluten powder, 5% of cocoa powder, 46% of eggs and 13% of sugar, and under the condition, the Q elastic steamed cake sensory evaluationThe score was 87.3.
