1. Too long or too short fermentation time: Tempura takes some time to grow and ferment during the fermentation process. If the fermentation time is too long, Tempura may be over-fermented, resulting in poor taste and bad smell; If the fermentation time is too short, the tempura may not be fully fermented and the taste will be hard.
2. Improper fermentation temperature: The temperature during fermentation has a great influence on the fermentation effect of Tianbei. If the fermentation temperature is too high, it may lead to over-fermentation of shellfish and poor taste; If the fermentation temperature is too low, it may hinder the fermentation of Tianbei, resulting in a hard taste.
3. Unsanitary fermentation environment: Environmental sanitation during fermentation is very important. If the fermentation container or yeast is polluted by bacteria or other pollutants, it may lead to the failure of the fermentation of Tianbei, the taste will be worse, and even there are food safety hazards.
4. Quality problem of yeast: Yeast is an essential microorganism in the fermentation process of shellfish. If the quality of yeast used is not good, it may lead to the failure of fermentation and the taste of shellfish will become worse.
In a word, the manifestations of fermentation failure of Tianbei may include too long or too short fermentation time, inappropriate fermentation temperature, unsanitary fermentation environment and yeast quality problems. If you encounter the failure of fermentation in the process of making Tianbei, it is suggested to check whether there are any problems in the above aspects in order to find out the problems and make adjustments.
