Abstract: The present invention is directed to a sponge cake premix that can be cooked easily with a microwave oven to prepare a sponge cake. A batter prepared by adding a thermocoagulation protein to a sponge cake premix containing as a main ingredient a cereal powder consisting of starch and a pregelatinized starch is cooked under heat with a microwave oven to obtain a sponge cake that permits eliminating the gum-like hard texture inherent in conventional sponge cakes of this type and exhibits a light and soft texture. The obtained sponge cake is free from bake shrinkage and exhibits a good-looking voluminous appearance.

Abstract: Water-thinned bean paste is chilled and non-fluidized, and the solidified bean paste is loaded into an air-permeable container, where the non-fluidized bean paste is freeze-dried and thus the water content is sublimed or evaporated from the entire surface of the bean paste. With the freeze-dried bean paste manufacturing method, a freeze-dried bean paste can be manufacture without requiring special facilities or an additive, at a low drying cost, and thus manufactured paste has an excellent flavor and taste and a high solubility to hot water even in a coarse block shape after being dried.
