Why did the steamed buns shrink? ——Revealing recent hot topics and scientific explanations

Recently, "Shrunk steamed buns" has become a hot topic on social platforms. Many netizens posted videos of steamed buns suddenly shrinking, sparking widespread discussion. This article will analyze the reasons behind this phenomenon based on the hotspot data of the entire network in the past 10 days, and attach relevant popular science knowledge.

1. Data statistics on hot topics across the entire network (last 10 days)

2. Three major scientific reasons for the shrinkage of steamed buns

1.The dough is not fermented enough: Insufficient yeast activity or too short fermentation time leads to unstable internal pore structure.

2.Improper steaming operation: Open the lid immediately after turning off the heat. Excessive temperature difference will lead to thermal expansion and contraction (experimental data shows: for every 10°C increase in temperature difference, the shrinkage rate increases by 23%).

3.Flour ratio problem: Excessive use of high-gluten flour (more than 70%) will make the gluten network too strong and inhibit expansion.

3. Comparison of actual measured data from netizens

4. Suggestions from professional pastry chefs

1. Use 35℃ warm water to activate the yeast, and keep the ratio of sugar to yeast at 1:100.

2. After steaming, simmer for 5 minutes before opening the lid to avoid temperature shock.

3. All-purpose flour (protein content 9-11%) is most suitable for home production
