second, analysis of the reasons for the collapse of Qifeng cake embryo and its solutions
first, insufficient protein distribution
Because if the protein distribution is insufficient, it does not reach dry foaming, and the protein state is unstable, which leads to shrinkage during the baking of the cake, so that the baked cake is not formed and thin, which eventually leads to the collapse of Qifeng cake embryo.
solution: beat the egg white until it is dry and foamed, and lift the egg head until the egg white is short and upright.
Second, the amount of sugar is insufficient
When making cakes, white sugar is mainly used to send out the protein, which makes the protein more delicate and smooth. If the amount of sugar is insufficient in the process of making cakes to send out the protein, the made cakes will not only collapse and harden, but also make Qifeng cake embryos not fluffy, have poor taste and poor color.
solution: increase the amount of sugar when sending the egg whites, thus increasing the sweetness of the cake and improving the color of the cake skin. During baking, the surface of the cake can better fill the gaps in the cake, making the batter smooth and delicate, and the taste soft. The baked Qifeng cake embryo is more fluffy and does not collapse.
Third, the baking temperature is not enough
In the process of making cakes, the lack of temperature in the oven will cause the cake embryo to collapse and not form. The temperature and time should be determined according to the size and category of the cake, and the small cake should be baked at high temperature and for a short time; Thick cakes need a low temperature and a long baking time.
when the cake weighs less than 1g, it needs to be baked at 2℃ for about 12 ~ 18 minutes, which is the same size as the fire.
when the weight is 1g～45g, it should be baked at 18℃ for 18 ~ 4 minutes, and the lower fire is bigger than the upper fire.
when the weight is 45g～1kg, it should be baked at 17℃ for about 4 minutes ~ 1 hour, and the fire is bigger than the fire.
solution: refer to the above-mentioned oven temperature schedule for making cakes, and adjust the oven temperature, so as to make Qifeng cake embryo fluffy without collapsing.
