Embodiment 1
[0020] In this embodiment, the dominant lactic acid bacteria Lactobacillus plantarum, Lactobacillus campylobacter, and Leuconostoc membranaceus glucan subspecies are selected as the strains of the starter. After the strains were activated and cultivated, the ratio of 2:2:1 was added to the seed medium with an inoculum of 3% for 24 hours, so that the pH dropped to about 3.2.
[0021] Among them, the dominant lactic acid bacteria are those with vigorous growth isolated in different fermentation periods of waxy corn as the dominant lactic acid bacteria. According to the sampling results of different fermentation periods, the vigorous degree of lactic acid bacteria was judged.
[0022] In this example, the seed culture medium includes 25g of glucose, 40ml of corn steep liquor, 5g of peptone, K 2 HPO 4 2g, Trisodium Citrate 5g, Sodium Acetate 5g, Tween 80 1ml, MgSO 4 ·7H 2 O 0.58g, MnSO 4 ·4H 2 O 0.25g, add water to make up to 1000ml, and sterilize at 121°C for 15min.

Embodiment 2
[0025] In this embodiment, the dominant lactic acid bacteria Lactobacillus plantarum, Lactobacillus campylobacter, and Leuconostoc membranaceus glucan subspecies are selected as the strains of the starter. After the strains were activated and cultured, the ratio of 2:2:1 was added to the seed medium with an inoculum of 5% for 18 hours. In this example, the seed culture medium is set as in Example 1.
[0026] The best fermentation process of waxy corn is: 3% inoculum, under the condition of 28 ℃, after 8 days of fermentation, the fermented waxy corn is washed with water, and then the water is removed; The finished sticky bean bag is made by cooking and freezing processes.
Embodiment 3
[0028] In this embodiment, the dominant lactic acid bacteria Lactobacillus plantarum, Lactobacillus campylobacter, and Leuconostoc membranaceus glucan subspecies are selected as the strains of the starter. After the strains were activated and cultured, the ratio of 2:2:1 was added to the seed medium with an inoculum of 4% for 20 hours. The best fermentation process of waxy corn is: 4% inoculum, at 26 °C, after 9 days of fermentation, wash the fermented waxy corn with water, and then dry the water; The finished sticky bean bag is made by cooking and freezing processes. In this example, the seed culture medium is set as in Example 1.
