The preparation method comprises the following steps:
mangosteen pretreatment: peeling and removing seeds of mangosteen, and putting the mangosteen into a juicer according to the mass ratio of material to water of 1:3 to obtain juice; adding pectinase in an amount of 0.01 wt% of the juice, and performing enzymolysis at 34 deg.C for 1 hr; filtering to obtain mangosteen juice.

Test example 1
The physical and chemical indexes of the mangosteen beer prepared in examples 1 to 3 and the commercial brewed beer were measured, and the results are shown in the following table:
TABLE 1 measurement data of physical and chemical indexes of beer
Test example 2
The nutrient contents of the mangosteen beer and the commercial fine-brewed beer prepared in the examples and the comparative examples were measured, and the results are shown in the following table:
TABLE 2 beer Nutrition ingredient determination data
as can be seen from the data in Table 1, the addition of the mangosteen juice of the present invention effectively increases the content of the nutrient components in the beer, and the addition of the mangosteen juice at the end of boiling can more effectively leach out the nutrient substances in the juice.
Test example 3
in order to better compare the taste and flavor of the beers, sensory evaluations were performed by 5 beer evaluation experts and 5 beer enthusiasts, and evaluation tests were performed on the mangosteen beers prepared in examples 1 to 3 and comparative example, and on the general brewed beers. The flavor profile was scored with a score ranging from 0 to 5. A score of 0 means that the attribute is not present, while a score of 5 indicates that the attribute is very strong. Sensory evaluation criteria are shown in table 3. In order to prevent the error caused by the sense fatigue, the principle of a small amount of times is followed. Blind tests were repeated for each wine and the average of the scores was recorded. The results are shown in the following table:
TABLE 3 evaluation test data
As can be seen from Table 2, the addition of the mangosteen and the special addition mode of the invention have favorable effects on the flavor, fullness and durability of the wine body of the mangosteen and reduce the bitterness of the beer. The nutrient substances in the mangosteen can be effectively leached out by adding the mangosteen juice after the boiling is finished, but the amount of the juice added in a sealed tank is reduced, and the flavor, the taste durability and the wine body fullness of the mangosteen in the beer are influenced. The amount of juice added as in example 3 was lower than that of example 1, and therefore the mangosteen flavor, the taste retention and the wine fullness were lower than those of example 1. In example 2, although the mangosteen flavor in beer could be improved by increasing the amount of mangosteen juice added, the malt flavor in beer was masked. The addition of the whole mangosteen juice at the end of boiling in comparative example 1 reduced the mangosteen flavor in the beer, and also resulted in a reduction in the flavor duration and body fullness. According to the invention, the mangosteen juice is added after the boiling is finished, so that the nutrient substances in the juice can be effectively leached, and certain performances such as mangosteen flavor and the like can be endowed to the beer; therefore, in comparative example 2, the mangosteen juice of 30% of the total mass of the mangosteen juice is added at the beginning of boiling, and then the rest of the mangosteen juice is added before can sealing, and compared with the case that the mangosteen juice is added after the end of boiling, the beer obtained by the method of comparative example 2 has the mangosteen flavor, the taste persistence of the mangosteen flavor and the wine fullness inferior to those of example 1 of the present invention.
