Embodiment 1

[0042] This embodiment provides a method for processing sourdough fermented rice noodle food based on dielectric regulation. This embodiment takes the preparation of corn cake as an example for illustration, and the method includes:

[0043] (1) Preparation of raw materials for corn cake: in parts by weight, take 2000 parts of corn grits, add 4000 parts of water, and soak for 4 hours; use colloid to grind the pulp, and pass through a 100-mesh sieve to obtain water-milled corn syrup; add the water-mill Lactic acid bacteria with 1% mass of corn steep liquor were fermented in a constant temperature incubator at 37°C for 20 hours to obtain fermented corn steep liquor with a fermentation pH of 4.2-4.4; dried at a low temperature in an oven at 42°C to obtain the fermented corn flour; in 300 parts The fermented corn flour, 240 parts of low-gluten wheat flour and 60 parts of soybean protein powder are compounded to obtain the raw material of corn cake.

[0044] (2) Preparation of the ...

Embodiment 2

[0050] This embodiment provides a method for processing sourdough fermented rice noodle food based on dielectric regulation. Taking the preparation of corn cake as an example for illustration, the method includes:

Abstract

The invention discloses a microwave processing method for a sour dough fermented rice flour food, and belongs to the technical field of food processing. The method comprises the following steps: adding a sour dough to steamed sponge cake raw materials, preparing a steamed sponge cake slurry, fermenting the steamed sponge cake slurry until the dielectric constant is 20-34, the dielectric loss is 6.3-9.0, the water content is 45-55% and the water activity is 0.920-0.980, and carrying out microwave heating to prepare the steamed sponge cake food. The sour dough is added to the steamed sponge cakeraw materials, and the regulation effect of the dielectric properties of the material system in the microbial fermentation process is used, so the problems of hard center, rough and dry surface and poor flavor of the product, caused by too fast and non-uniform heating in microwave heating, are solved without adding a food additive; and the microwave cooking process can be easily instantaneously controlled, has a high heating efficiency, is selective, and can achieve sterilization during heating, so the method has the advantages of simplicity, low energy consumption, energy saving and environmental protection.

Description

technical field [0001] The invention relates to a microwave processing method for sourdough fermented rice noodle food, belonging to the technical field of food processing. Background technique [0002] Fermented rice noodle food is the traditional staple food source in my country. At present, common fermented rice noodle foods include hair cakes, steamed buns, Hanamaki, etc., which are generally made of rice / flour as the main raw material, and are prepared through blending, fermentation, and aging processes. They have unique flavors, rich nutrition, and soft mouthfeel. The curing process is an essential step in the production of fermented rice noodles, because it involves key steps such as starch gelatinization, protein denaturation, volume expansion, and water evaporation. , Long product production cycle, large nutrient loss during processing, easy microbial corruption, short shelf life, unstable product quality, insufficient flavor quality and other prominent problems, i...
