Manufacturing process of a bean curd for using a rice

The present invention relates to a method of making bean curd using rice, in which 65-70 wt % of soya beans and 30-35 wt % of parched rice in about a total weight of 5 kg for one block of bean curd are soaked, and in which the soya beans are soaked for about 8-12 hours and the parched rice is soaked for about 2 hours in water.
The soya beans and parched rice are mixed and the mixture is put into a mill to grind it into powder, and then 15 g of a defoaming agent that suppresses foaming and 60 g of water are added into the mixture of ground soya beans and parched rice and they are mixed evenly.
Bean curd refuse is filtered by passing the mixture through a filter, and then the remaining parched rice/soya bean milk is boiled at 80-99° C.
42 g of magnesium chloride, which is a coagulant, is added to the heated parched rice/bean curd milk, 14 g of salt or JukYum (salt roasted in bamboo) is added together with 45 g of water, and they are mixed and coagulated.
The coagulated parched rice/bean curd milk is mashed to have a diameter of about 3-4 cm and then the mashed rice-bean curd is pressed, such that bean curd using rice is completed.
Accordingly, consumers' health can be improved by the bean curd containing rice, and it is possible to satisfy various tastes of the consumers by providing high-quality bean curd.
