Embodiment 1~3、 comparative example 1
[0095] (Example 1~3, comparative example 1~3) hybrid breeding and bacterial strain selection
[0096] Strains isolated from nature, strains produced by hybridization that have higher candy fermentability than our Saccharomyces cerevisiae preserved strain (GA), and strains that are resistant to freezing are used as primary strains.
[0097] The above-mentioned original strain of high sugar dough fermentability with the above-mentioned GA equivalent or higher was obtained as follows.
[0098] First, using GA in the state of fresh yeast before long-term refrigerated storage, high sugar dough A was prepared in the composition of Table 1 above, and fermented at 38° C. for 2 hours to measure the fermentability (57 mL).
[0099] Next, a variety of baker's yeast belonging to Saccharomyces cerevisiae isolated from soil, ponds, rivers, etc. by conventional methods were operated in the same manner as GA, and the high sugar dough fermentation power was measured, and the high sugar dough f...
Embodiment 4~6、 comparative example 4~6
[0115] (embodiment 4~6, comparative example 4~6) make bread test
[0116] Table 11 shows the results of evaluating the freeze-resistant fermentability of strains stored in a refrigerator (about 5° C.) for 6 weeks using the bread-making formulations shown in Table 10.
[0117] As can be seen from the results in Table 11, when the bread baked in Examples 4-6 was frozen for 1 week or 3 months, compared with the bread baked in Comparative Examples 4-6, significantly increased in size.
[0118] Therefore, it can be seen that when the yeast of the present invention is compared with the three strains of commercially available yeast, even when the bread dough made by using the bacterial cells after long-term refrigerated storage is subjected to long-term freezing for 1 week to 3 months, it is also shown that the obtained The functionality of full bread volume.
