The invention further aims to provide a preparation method of the kidney bean microwave cake, the preparation method is simple, convenient and easy to obtain, defoaming of cake paste in the baking process is avoided in a rapid microwave baking mode, and the prepared cake is fine and smooth in tissue, unique in flavor, golden in color, melting in the mouth and good in taste.
In order to further achieve the purpose, the invention adopts the following technical scheme: the premixed kidney bean cake flour comprises the following raw materials in parts by weight: 20-22 parts of kidney bean powder, 78-80 parts of low gluten flour, 1.05-1.2 parts of disodium dihydrogen pyrophosphate, 0.9-1.05 parts of sodium bicarbonate, 0.24-0.3 part of sodium dihydrogen phosphate, 0.24-0.3 part of calcium carbonate, 0.35-0.4 part of glyceryl monostearate, 0.3 part of edible corn starch, 10 parts of milk powder and 0.4 part of citric acid.
Preferably, the low gluten flour protein content is less than 9.5%. Flour with less than 9.5% protein is beneficial for the puffing of cake.
Preferably, the milk powder is full-cream milk powder with protein content not lower than 24% and fat content not lower than 30%. The whole milk powder is beneficial to the foaming and emulsification of the cake.
Correspondingly, the invention also claims a preparation method of the kidney bean cake premixed flour, which comprises the following steps: grinding the raw material kidney bean dry seeds until kidney bean powder is fine and smooth and has no obvious granular sensation,
weighing kidney bean powder, low-gluten flour, disodium dihydrogen pyrophosphate, sodium bicarbonate, sodium dihydrogen phosphate, calcium carbonate, glyceryl monostearate, edible corn starch, milk powder and citric acid according to the weight parts, uniformly mixing, and sieving the mixed powder completely through a CQ20 sieve specified in GB/T5507.
Correspondingly, the invention also claims a kidney bean microwave cake, which comprises eggs, edible oil, water, white granulated sugar and the kidney bean cake premixed flour, wherein the mass ratio of the eggs, the edible oil, the water, the white granulated sugar to the kidney bean cake premixed flour is 250-260: 35-40: 35-40: 75: 100.
correspondingly, the invention also claims a preparation method of the kidney bean microwave cake, which is prepared by the following operation steps:
step (1), removing shells of eggs, weighing, separately containing egg white and yolk, and uniformly stirring the yolk; adding white granulated sugar into egg white for three times, and beating the egg white until the egg white is hard to foam;
step (2), adding the premixed powder of the kidney bean cake, water and edible oil into the yolk in the step (1) in sequence, and stirring uniformly;
step (3), firstly, 1/3 egg white paste in the step (1) is added into the egg yolk paste, and the mixture is turned and stirred uniformly; pouring the mixture into the rest egg white paste, and stirring the mixture uniformly with gentle hand speed to avoid the bubbles from disappearing too quickly;
step (4), putting the prepared cake paste into a cake mould, adding 2/3 with the modulus of the cake mould, and then vibrating several cake moulds to remove air in the paste;
and (5) putting the cake mould into a microwave oven, and baking for 2.5-4 min under the microwave oven of 700-800W to obtain the cake mould.
Preferably, the three adding amounts of the white granulated sugar in the step (1) respectively account for 33.33%, 48% and 18.67% of the total mass of the white granulated sugar.
Compared with the prior art, the invention has the following advantages and beneficial effects:
(1) the invention provides a brand-new kidney bean food preparation process, which is characterized in that rich protein, amino acid, vitamin, mineral substance and dietary fiber of kidney beans are kept, and soybean lipoxygenase, trypsin inhibitory factor, soybean agglutinin and the like are killed by heating for 2.5-4 min at 700-800W of microwave, so that anti-nutritional factors and beany flavor of the kidney beans are quickly removed. Under the current consumption trend of paying attention to nutrition and taste, new consumption options are provided for consumers.
(2) Compared with cake premixed flour in the current market, the kidney bean cake premixed flour provided by the invention makes up for the unbalance of amino acid structures, and the essential amino acid composition of the kidney bean cake premixed flour meets the FAO/WHO standard mode, so that the nutritional value of the instant food product is greatly improved.
(3) The foaming agent is added into the prior cake premixed flour to enable a cake to be fluffy and moist, but the problems of defoaming of cake paste, compact tissue after baking and the like are easily caused after eggs and edible oil are added. The protein content of the kidney bean powder added in the premixed kidney bean cake flour is up to 20.3-27.2%, and the good surface activity is endowed by the hydrophilic group and the hydrophobic group of the kidney bean protein. Compared with cake premixed flour without kidney bean flour, the kidney bean cake premixed flour endows cake paste with high viscosity due to high protein concentration, and is beneficial to forming a multilayer binding protein film on an interface when cake is whipped. Therefore, compared with the embodiment without the kidney bean powder, the embodiment with the corresponding weight of the kidney bean powder added in the invention has the appearance leavening volume increasing proportion of about 23 percent; and in the examples, due to the proper concentration of the kidney bean protein, a thicker protein adsorption film is formed through the hydrophobic interaction and the hydrophobic combination effect between the proteins, and the improvement on the foam stability of the cake paste reduces the defoaming effect of the fat component in the cake paste.
When the conventional cake premixed flour is used for making a microwave cake, the problems of unbalanced cake flavor, dryness and hardness after placement, rough mouthfeel and the like are easily caused due to the uneven microwave heating mode and short heating time. In the manufacturing process of the premixed kidney bean cake flour, the kidney bean flour with the optimal mass ratio is used, and the emulsifying property of kidney bean protein enables polar groups and non-polar groups to be directionally arranged on an interface of a water phase and an oil phase in the stirring process of cake paste, so that the interfacial tension is reduced, the water phase, the oil phase and a gas phase brought by stirring are uniformly dispersed, the stability of the system is kept, and the guarantee is provided for the elastic and fluffy cake taste. And in the embodiment of the kidney bean powder and the flour with the optimal mass ratio, the kidney bean protein groups can be combined with the hydroxyl groups of amylose in the flour, so that the problems of water loss after the standing and flavor imbalance caused by the wrapping of flavor substances in a crystallization area due to the formation of the starch crystallization area are avoided.
The kidney bean powder, the composite foaming agent, the citric acid and the like in the kidney bean cake premixed flour in the preferable proportion are compounded, so that the convenience in making the microwave cake is ensured, and meanwhile, the good foamability and the excellent foam stability of the cake body are ensured. The kidney bean protein enhances the supporting effect of the protein component when the cake body is fluffed; also, the antifoaming effect of the yolk and other fat components to the cake batter is weakened, and the cake prepared has a fluffy and uniform texture.
(4) The kidney bean microwave cake provided by the invention is simple and easy to obtain, defoaming of cake paste in a long-time baking process is avoided in a rapid microwave baking mode, and the prepared cake is fine and smooth in tissue, unique in flavor, golden in color, melting in the mouth and good in taste.
