[0093] Comparative Example 2
[0094] A method for preparing a compressed condiment is based on Example 1, but without using eggplant powder.
[0095] The methods of Example 1, Example 4, Example 5, Example 6, Comparative Example 1 and Comparative Example 2 were used to prepare 10 g / tablet compressed condiments and evaluate the relevant indicators. The evaluation results are shown in Table 1.

[0098] The molding rate in Table 1 is the number of molded pieces for preparing 100 pieces / 100*100%. Figure 1 As shown, it is a molded sample. This type of product is defined as molded. Figure 2 The sample shown is not well formed, and this type of product is defined as unformed; the appearance is directly observed with the naked eye; the aroma is determined by referring to GBT 14454.2-2008, the method for evaluating the aroma of spices; the moisture content is determined by referring to GBT12729.6-2008, the determination of moisture content of spices and condiments (distillation method); the dissolution effect is determined by the following steps: heat 1000mL of water to 100℃, put in 1 piece of compressed condiment, and stir at 90rpm to dissolve.
[0100] The 10 g / tablet compressed condiments prepared in Example 1, Example 4, Example 5, Example 6, Comparative Example 1, and Comparative Example 2 were sealed in ziplock bags, 40 tablets in each bag, and stored under the same environment for two years. During this period, the bags were opened for ventilation once every week for 20 seconds each time. After two years, the bags were taken out for evaluation of relevant indicators. The evaluation method was the same as that in Table 1. The results are shown in Table 2.
