Preparation method of fermented rice cakes and fermented rice cake products

Abstract

The present invention discloses a preparation method of fermented rice cakes and fermented rice cake products. The preparation method of the fermented rice cakes comprises the following steps: addingrice to water for soaking; conducting grinding and sieving of the soaked rice to obtain rice slurry; adding compound enzymes at a condition of 40-45 DEG C into the rice slurry for treatment of 60-120min to obtain enzymatic hydrolyzed rice slurry; wherein the compound enzyme comprises glucoamylase and debranching enzymes according to a mass ratio of 1:(1-2) and an addition amount of the compound enzyme is 0.1%-0.2%; conducting plate-frame pressure filtration of the enzymatic hydrolyzed rice slurry, conducting washing for 2-3 times to obtain washed filter cake, and drying the washed filter caketo obtain special powder for the fermented rice cakes; and using the special powder for the fermented rice cake to prepare the fermented rice cake. In the preparation method of the fermented rice cakes, the compound enzyme is used during preparation process of the special powder for the fermented rice cakes for treatment, rice flour DE value and amylose content are improved, subsequent fermentation efficiency and use efficiency of yeasts to the rice flour are greatly improved, and fermentation time is shortened.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a preparation method of rice-fat cake and a rice-fat cake product. Background technique [0002] Rice hair cake is made from indica rice after soaking, grinding, fermenting and heating with steam. The finished product has a fine network structure, soft taste, pleasant wine aroma and lactic acid flavor produced by fermentation, and is easy to be digested and absorbed by the human body. A typical representative of China's rice products, deeply loved by consumers. [0003] However, the production of rice cakes has not attracted enough attention from researchers, and it is still in the stage of manual production. On the one hand, the traditional production process of rice cakes lacks the guidance of scientific theory. The production experience comes from folk accumulation, and the product quality is not stable. , it is difficult to meet the growing consumer deman...

[0003] However, the production of rice cakes has not attracted enough attention from researchers, and it is still in the stage of manual production. On the one hand, the traditional production process of rice cakes lacks the guidance of scientific theory. The production experience comes from folk accumulation, and the product quality is not stable. , it is difficult to meet the growing consumer demand; on the other hand, the traditional production method of rice cakes begins with soaking rice and refining, and the manpower and material resources required at this stage have increased the burden on producers
