Five, chewing gum formula optimization design
5.1 optimization design method and evaluation criteria
On the basis of a single-factor test, the ratio of xylitol to sorbitol is fixed to be 4:1 according to sensory evaluation and investigation results, and L is designed according to the test factors of the content of mixed sugar, the content of gum base and the content of dihydromyricetin9(3)3The orthogonal test, factors and levels are shown in Table 8. The best formula of the dihydromyricetin lipid-lowering chewing gum is screened out by taking sensory evaluation as an index. As it can be found in experiment 1.4.1, the content of baicalin has little influence on the taste of the chewing gum, so that the baicalin is not taken into experimental factors during the optimization design.
And randomly selecting 90 students of the copper kernel professional technical institute for sensory evaluation from the aspects of color, texture, taste, smell and the like of the product. By adopting the percentage, the color and luster accounts for 20 minutes, the texture accounts for 15 minutes, the mouthfeel accounts for 25 minutes, and the smell accounts for 40 minutes. The sensory evaluation score values are shown in table 9, and the results of the orthogonal test are shown in table 10.

Figure BDA0002922309430000181
According to the experimental results, the main and secondary influence factors influence the taste and the chewing gum quality C > A > B, and the optimal formula of the chewing gum is A2B3C3, namely 30g of gum base, 70g of mixed sugar and 2.5g of dihydromyricetin. Since A2B3C3 is not in the orthogonal test, a validation experiment was required for the optimal formulation combination for chewing gum. The average composite score of 5 validations was 90 points, so the optimal formula combination was A2B3C 3.3 batches are prepared according to the optimal formula, and the obtained product has ideal effects in hardness, color, mouthfeel and appearance.
