1. 1000g of wheat flour, 25g of commercially available baking powder, 500g of sugar, 500g of fat and oil and 80g of eggs are weighed respectively.
The remaining steps were the same as in example 4, steps 3-6.
The frozen green articles and frozen and baked products prepared in examples 1 to 10 and comparative examples 1 to 12 were tested, and the test results are shown in table 4, and the test methods are as follows:
the green body cracking rate test method comprises the following steps: 100 green bodies were frozen for a period of time (5 days, 10 days or 15 days) and observed for cracking and the number of cracked green bodies was recorded. Wherein the green body is significantly cracked or has been incompletely treated as cracked, and the surface has fine cracks or is completely treated as uncracked.
Green body cracking rate is the number of cracked green bodies/total amount of green bodies × 100%.
Diameter test method: randomly taking 10 baked walnut cakes, respectively measuring the diameters of the walnut cakes by using a ruler, and recording the diameters as Dn (n is 1-10), then averaging to obtain the final diameter D, wherein the calculation formula is as follows:
D=(D1+D2+D3+D4+D5+D6+D7+D8+D9+D10)/10

Figure BDA0002462503290000141
Figure BDA0002462503290000151
As can be seen from the experimental results in Table 4, the cracking rates of the green compacts in examples 1 to 10 after the green compacts were frozen for 5 days, frozen for 10 days, and frozen for 15 days were respectively 2.80 to 4.00%, 4.50 to 5.50%, and 4.80 to 6.30%, which were lower than those of comparative examples 1 to 12, i.e., 4.10 to 10.0%, 5.80 to 13.00%, and 7.00 to 15.00%; the green compacts were frozen for 5 days, frozen for 10 days and frozen for 15 days, respectively, and the diameter reduction rates of the baked products of examples 1 to 10 were 0.21 to 0.54%, 0.39 to 0.98% and 0.68 to 1.41%, respectively, which were lower than those of comparative examples 1 to 12, i.e., 0.72 to 5.26%, 2.38 to 12.35% and 3.63 to 16.97%.
As can be seen from the results of comparative examples 1 to 3 and examples 8 to 10 in Table 4, the frozen green bodies produced according to the present invention were reduced in both the green body cracking rate during frozen storage and the diameter reduction rate of the baked products after frozen storage, as compared with the frozen green bodies produced using the leavening agent lacking the inactivated yeast in the components.
As can be seen from the results of comparative examples 4 to 6 and examples 8 to 10 in Table 4, the frozen green bodies produced according to the present invention were reduced in both the green body cracking rate during frozen storage and the diameter reduction rate of the baked products after frozen storage, as compared with the frozen green bodies produced by using ordinary sodium bicarbonate in place of the sodium bicarbonate-embedded leavening agent having the same sodium bicarbonate content.
Experimental results show that the frozen walnut cake green body leavening agent provided by the invention can be used for obviously improving the cracking problem in the frozen storage process of the frozen walnut cake green body and the problem that the diameter of a product baked after the frozen storage of the frozen walnut cake green body is smaller.
The foregoing is considered as illustrative and not restrictive in character, and that various modifications, equivalents, and improvements made within the spirit and principles of the invention are intended to be included within the scope of the invention.
