Abstract

The invention discloses a preparation method, product and application of special rice flour for steamed rice cakes. The preparation method comprises the following steps: grinding a rice raw material,performing cleaning and soaking, and performing crushing to obtain wet rice milk; adding tea polyphenol palmitate into the wet rice milk, carrying out ultrasonic treatment, and carrying out filter pressing treatment to obtain a rice flour filter cake subjected to filter pressing; and crushing the rice flour filter cake, treating the crushed rice flour filter cake in a closed environment at 90-110DEG C for 1.5-3h, performing drying, and sieving the dried rice flour filter cake through a vibrating screen with a pore sieve of 0.15-0.18 mm to obtain the special rice flour for the steamed rice cakes. According to the preparation method of the special rice flour for steamed rice cakes, tea polyphenol palmitate is added, treatment is conducted for 1.5-3 h in a closed environment at a temperatureof 90-110 DEG C, and the adding amount of the tea polyphenol palmitate is optimized. Under the synergistic effect of all the processes, the prepared rice flour has the advantages of large hardness ofrice flour gel, high elasticity, low retrogradation value of the rice flour, and high water binding capacity.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a preparation method of special rice flour for rice cakes and its product and application. Background technique [0002] Rice products use water or oil as the heat exchange medium to gelatinize the starch in the rice products and deform the protein, thus a type of traditional food with rich nutritional value and special fragrance. Rice cake is a traditional rice fermented product in my country. It is made from indica rice through soaking, refining, fermentation and steaming. Rice hair cake has a honeycomb structure, delicate taste, special flavor of fermentation, easy to be digested and absorbed by the human body, rice hair cake is a steamed food, and has the characteristics of nutrition and health. At present, rice hair cake has a long production process, many supporting equipment, and high production cost. [0003] How to make a kind of special rice flour ...
