< statistics of Experimental data >

The raw materials of examples 1 to 10 and comparative examples 1 and 2 were purchased from the same lot, and the jelly manufactured by the methods of examples 1 to 10 and comparative examples 1 and 2 was scored by sensory evaluation of 50 students for each sample, evaluated according to the sensory evaluation criteria set forth in table 1, discarded as the highest score and the lowest score, and the average value of each sensory score was calculated and recorded, and the average values were added to obtain the final sensory score of the jelly as shown in table 2.

TABLE 1 sensory Scoring criteria for jelly

TABLE 2

According to the data statistics of table 2, the mass ratio of the selected wampee pulp to the sweet tea water in examples 1 to 3 is basically 2:3, at the moment, the white color and the brown color of the wampee pulp are uniform and moderate, the scores of the statistical color, the statistical tissue state, the statistical flavor and the statistical taste are better, and the total score is more than 90. Example 4 selecting a material with a mass ratio of wampee pulp to sweet tea water of more than 2:3, a light color, a basically uniform color and slightly sour flavor; example 5 the mass ratio of the selected wampee pulp to the sweet tea water is further obviously more than 2:3, the color of the tea is seriously dark or light, the color of the two is seriously distributed, and the taste and smell are seriously sour, so that the analysis shows that the selection ratio of the main materials of the wampee pulp to the sweet tea water has a great influence on the color, the taste and the smell of the prepared jelly. The compound jelly glue powder in the embodiment 1 is prepared from konjac gum and carrageenan according to the mass ratio of 1:2, and the jelly is soft, moderate in elasticity and good in chewiness; the compound jelly glue powder of the embodiment 6 is prepared from konjac gum and carrageenan according to the mass ratio of 1:1, and the jelly is hard, has no elasticity and is not good for chewing; the compound jelly glue powder of the embodiment 7 is prepared from konjac gum and carrageenan according to the mass ratio of 1:3, and the jelly is soft, poor in elasticity and poor in chewiness; therefore, the compound gel powder of the jelly has larger influence on the tissue state and the taste of the jelly by selecting the proportion of the konjac gum and the carrageenan. The main material wampee pulp selected in the embodiment 8 is obtained by beating the pericarp and the pulp into raw pulp and fermenting, and through the steps of the invention, the defects caused by bitter and coarse pericarp of wampee are overcome, the nutrient content of the pericarp of wampee can be fully utilized, and the pericarp waste and peeling procedures are reduced. According to the invention, the peel and the pulp are beaten into the original pulp, and the original pulp, the cellulase powder and the yeast powder are mixed and fermented, so that the prepared jelly is better evaluated in color, tissue state, taste and smell and mouthfeel, and has high score; the jelly obtained in comparative example 1, which was used for preparation without fermentation, was significantly poor in evaluation of color, texture state, flavor, smell and taste; the jelly obtained in comparative example 2, which was used for preparation through mixed fermentation with cellulase powder and lactic acid bacteria powder, was significantly deteriorated in evaluation of texture state and flavor and smell. Example 9 and example 10 are improvements in the preparation of sweet tea water, and after sweet tea is soaked and washed with normal-temperature rice washing water, the two-stage tea water is taken as a main material for making jelly, which improves tea aroma and sweet taste, and obviously improves the evaluation of taste and smell of the jelly.
