And secondly, whipping the cream product to form a plurality of milk caps, wherein the plurality of milk caps are formed by whipping the cream with the whipping assistant in each embodiment and each comparative example respectively.
The issuing method comprises the following steps:
the whipping aid of each example and the whipping aid of the comparative example are respectively mixed with cream with the temperature of 4.0 ℃ according to the mass ratio of 1:4 to obtain different pre-whipped mixtures, and the different pre-whipped mixtures are whipped to a semi-flowing state by a chef machine according to the same stirring intensity, so that a plurality of milk caps are obtained, and the whipping rate of each milk cap is 1.8 +/-0.1.
And thirdly, testing the flavor, stability and a foaming window period of different kinds of milk caps.
(1) Testing the flavor of different kinds of milk caps
In the flavor test, a user test group containing 50 persons is constructed to evaluate the flavor of different milk caps, and each user in the user test group consumes milk tea once a week or more frequently. Each user scores three dimensions of fragrance, texture and taste of different milk caps, and then an average value is taken, wherein the full score of each dimension is 5. Adding different kinds of milk caps into the same tea beverage to prepare a plurality of cups of milk cap beverages with different kinds of milk caps. And (4) carrying out comprehensive application taste scoring on the milk-covered drink by each user in the user test group, and then taking an average value, wherein the full score is 5.
Table 1 shows the results of scoring in different scoring dimensions for each example and for the scaled, corresponding assisted-hit milk lids in the flavor test.
TABLE 1
Figure BDA0003673374070000141
As can be seen from table 1, the milk lids whipped with the whipping aid of examples 1 to 4 are more popular with consumers and the user experience is better than the milk lids whipped with the whipping aid of each proportion.
(2) Testing the beating window period of different milk caps
The foaming auxiliary agents of the examples and the comparative examples are respectively mixed with cream with the temperature of 4.0 ℃ according to the mass ratio of 1:1 to obtain different pre-foaming mixtures, the different pre-foaming mixtures are stirred and foamed to a semi-flowing state by a chef machine according to the same stirring intensity to obtain a plurality of milk caps, the foaming rate of each milk cap is 1.8 +/-0.1, and the respective foaming and forming time of the different milk caps is recorded.
And continuously stirring and whipping the whipped milk caps of different types until the milk caps are changed into a flowing state from a semi-flowing state, and recording the whipping transition time of different milk caps. The frothing window period (also called the frothing window time) of different milk caps is the time difference between the frothing transition time and the frothing shaping time.
Table 2 shows the strike window time, strike over time, and strike set time during the strike window period test for different types of milk caps that were struck with the strike aid of each example and comparative example, respectively.
TABLE 2
Figure BDA0003673374070000151
As can be seen from table 2, compared with the milk caps subjected to the auxiliary frothing by the frothing aids in each proportion, the milk caps subjected to the auxiliary frothing by the frothing aids in the embodiments 1 to 4 have a longer frothing window period, so that the frothing operations of the staff in the beverage shop are easy, the appearance and quality of the milk caps are prevented from being influenced by excessive frothing, and the drinking experience of users is better.
(3) Testing the stability of different milk caps
This part of the stability test included a temperature stability test of the milk cap on drinks with different temperatures and a PH stability test of the milk cap on drinks with different PH values.
With the deep development of the milk cap beverage, the beverage matched with the milk cap can be cold beverage or hot beverage, so that the milk cap is required to have stability in a wider temperature range to meet the requirements of different users on the temperature of the beverage.
Table 3 shows the settling time for some examples and some comparative examples when they were overlaid on beverages at different temperatures, calculated as the time counted from the overlaying of the milk lid onto the beverage surface, to the complete blurring of the interface of the milk lid with the beverage, and the end of the time counted when the milk lid was incorporated into the beverage, with a period of time noted as the settling time for the milk lid.
TABLE 3
Figure BDA0003673374070000161
As can be seen from examples 2 and 3 and comparative example 1 in table 3, the stability of the whipping aid-whipped milk cap containing α -cyclodextrin in the stabilizer was better in both cold and hot drinks than the whipping aid-whipped milk cap containing no α -cyclodextrin in the stabilizer. According to the comparative example 3, the example 2 and the example 3 in the table 3, the mass percentage of the protein in the whipping aid is between 2% and 6%, which is beneficial to improving the stability of the milk cover in cold drink and hot drink, and the mass percentage of the protein in the whipping aid has great influence on the performance of the whipping aid.
Table 4 shows the settling time for some examples and some comparative examples when overlaid on beverages of different PH, calculated as the time counted from the overlaying of the milk cap onto the beverage surface, to the complete blurring of the interface of the milk cap with the beverage, and the end of the time counted when the milk cap is incorporated into the beverage, with a period of time noted as the settling time of the milk cap.
With the deep development of milk cap drinks, the drinks matched with the milk cap are not limited to neutral drinks, but also can be acidic fruit juice drinks, so that the milk cap is required to have stability in a wider pH value range to meet the requirements of different users on the drinks.
TABLE 4
Figure BDA0003673374070000171
From table 4, the stability of the acidic to neutral beverage of the whipped milk topping assisted by the whipping aid containing the alpha-cyclodextrin in the stabilizer is better than that of the acidic to neutral beverage of the whipped milk topping assisted by the whipping aid not containing the alpha-cyclodextrin in the stabilizer. The milk cap which contains the beating auxiliary agent of alpha-cyclodextrin in the stabilizer and assists beating has stability in a wider pH value range, can be suitable for various drinks, and has better drinking experience for users.
