Examples of effects

Effect example of the present invention the effect of the pink balls prepared in examples 1 to 8 and comparative examples 1 and 2 was verified.

In order to prove the effect of the flour ball, the flour balls prepared in the examples 1-8 and the comparative examples 1 and 2 adopt the same cooking method, and for the taste and the appearance, after cooking is finished, 10 sensory evaluation engineers with abundant experience are requested to give scores according to 1-10, and the average value of the scoring results is taken; the hardness test is to place the cooked non-white flour balls in the ice drink and record the hardness change of the flour balls between 0 and 6 hours, wherein the hardness is measured by adopting a texture analyzer; the white heart rate was obtained by dividing the number of white heart pink circles observed to be recorded by the total number of pink circles. The results are shown in Table 1.

Table 1: verification form for powder ball effect

Firstly, as can be seen from the powder circles 1 to 3 in table 1, the white heart rates of the three are all 0%, the main difference is in the Q elasticity degree of the mouthfeel, the glittering and translucent appearance and the hardness after different time of placing in ice drinks, and the main difference of the powder circles 1 to 3 is in the mass ratio of the tapioca starch to the modified starch, which indicates that the mass ratio of the tapioca starch to the modified starch affects the mouthfeel, the appearance of the powder circles and the hardness after different time of placing in the ice drinks, but has no obvious influence on the white heart rate, wherein when the mass ratio of the tapioca starch to the modified starch is 4:1, the overall mouthfeel and the appearance score of the powder circles are the highest, the hardness of 0h and 6h in the ice drinks is the lowest, and the hardness increases the slowest along with the prolonging of the placing time, which can also be seen from fig. 1, when the mass ratio of the tapioca starch to the modified starch is 4:1, the hardness-time curve rises gently, the flour balls prepared in the proportion are stable in ice drinks and are not easy to age and harden.

Secondly, as can be seen from the pink circles 3 to 7 in the table 1, the five ingredients have no difference in taste, appearance and hardness, and the white heart rates are not much different and are all below 8%, wherein the white heart rate of the pink circle 3 is 0%, and the difference between the pink circle 3 and the pink circle 7 is mainly that the selection and the proportion of the hydrophilic colloid are inconsistent in the hydrophilic colloid compounding process, the overall white heart rate is not more than 8%, and the best effect is achieved when the pink circle 3, namely xanthan gum and guar gum are compounded in a mass ratio of 2: 1.

Finally, comparing the flour balls 9 and 10 with the flour balls 3-8, it can be found that although there is no obvious difference in taste, appearance and hardness, the difference in white heart rate is large, and the difference in white heart rate brings slight difference in taste and appearance. It can be seen from the pink balls 3 and the pink balls 10 that the compounding ratio of the hydrophilic colloid brings obvious influence on the white heart rate, wherein the pink balls 3 adopt a compounding mode that the mass ratio of the xanthan gum to the guar gum is 2:1, and the pink balls 10 adopt a compounding mode that the mass ratio of the xanthan gum to the guar gum is 1:1, so that the white heart rate of the pink balls 3 is 0%, and the white heart rate of the pink balls 8 reaches 48%. As can be seen from the rice ball 3 and the rice ball 9, the selection of the hydrophilic colloid in the hydrophilic colloid compounding can also bring obvious influence on the white heart rate, wherein the rice ball 3 adopts a compounding mode that the mass ratio of xanthan gum to guar gum is 2:1, the rice ball 9 adopts a compounding mode that the mass ratio of xanthan gum to CMC is 2:1, and as a result, the white heart rate of the rice ball 3 is 0%, and the white heart rate of the rice ball 9 reaches 79%. A comprehensive comparison of the examples and comparative examples further demonstrates that the choice of hydrocolloids and the choice of the ratio in the hydrocolloid formulation is an important influencing factor for the white heart rate.
