Embodiment 1

[0051] A certain amount of wheat flour was weighed, the alkaline water with pH 9.5 of 38% of the mass of wheat flour, and the liquid monocaprylic acid glyceride (purity 99%, the same below) of 0.1% of the mass of wheat flour were weighed. Firstly, dissolving monocaprylic acid glyceride in an appropriate amount of alkaline water to obtain a mixed solution of alkaline water monocaprylic glyceride, then adding the mixed solution into flour and stirring in a vacuum dough mixer to make the wheat flour fully absorb water.

[0052] Put the stirred bean dregs-like dough into a thermostat at 25°C to proof for 20 minutes to prevent the formation of large dough. Adjust the distance between the rollers of the noodle press to 4mm, and gradually reduce the distance between the rollers as the number of times of sheeting increases, and finally thin the dough sheet to 2mm, and use a 2mm flat noodle knife to cut into strips to obtain fresh wet noodles, which are fresh-keeping Chongqing small noo...

Embodiment 2

[0055] A certain amount of wheat flour was weighed, alkaline water with a pH of 10.0 of 38% of the mass of the wheat flour, and liquid monocaprylic acid glycerin of 0.08% of the mass of the wheat flour were weighed. Firstly, dissolving monocaprylic acid glyceride in an appropriate amount of alkaline water to obtain a mixed solution of alkaline water monocaprylic glyceride, then adding the mixed solution into flour and stirring in a vacuum dough mixer to make the wheat flour fully absorb water.

[0056] Put the stirred bean dregs-like dough into a thermostat at 25°C to proof for 20 minutes to prevent the formation of large dough. Adjust the distance between the rollers of the noodle press to 4mm, and gradually reduce the distance between the rollers as the number of times of sheeting increases, and finally thin the dough sheet to 2mm, and use a 2mm flat noodle knife to cut into strips to obtain fresh wet noodles, which are fresh-keeping Chongqing small noodles .

Embodiment 3

[0059] A certain amount of wheat flour was weighed, alkaline water with pH 11 of 38% of the mass of the wheat flour, and liquid monocaprylic acid glycerin of 0.06% of the mass of the wheat flour were weighed. Firstly, dissolving monocaprylic acid glyceride in an appropriate amount of alkaline water to obtain a mixed solution of alkaline water monocaprylic glyceride, then adding the mixed solution into flour and stirring in a vacuum dough mixer to make the wheat flour fully absorb water.

[0060] Put the stirred bean dregs-like dough into a thermostat at 25°C to proof for 20 minutes to prevent the formation of large dough. Adjust the distance between the rollers of the noodle press to 4mm, and gradually reduce the distance between the rollers as the number of times of sheeting increases, and finally thin the dough sheet to 2mm, and use a 2mm flat noodle knife to cut into strips to obtain fresh wet noodles, which are fresh-keeping Chongqing small noodles .

Abstract

The invention belongs to the technical field of cooked wheaten food quality guarantee, and discloses a method for prolonging the shelf life of Chongqing spicy noodles. The method comprises the steps: selecting materials; preparing alkaline water: electrolyzing food-grade potassium carbonate through an alkaline water generator, and performing membrane filtration for different time to obtain alkaline water without sodium ion content; selecting glycerol monocaprylate: selecting the glycerol monocaprylate in a powdery or liquid state, wherein the content of the glycerol monocaprylate reaches 99% or above; curing: fermenting the small dough which is stirred and mixed into the soybean curb residue shape; rolling: rolling the dough into dough strips; slitting: cutting the dough slices into noodles with a specified shape and consistent width by a noodle knife; and packaging: packaging the formed Chongqing spicy noodles by adopting a food-grade packaging material. The alkaline water containing potassium ions is adopted so that the original characteristics of light yellow color and moderate alkaline taste of Chongqing spicy noodles are still kept, and the smoothness of the noodles is good. The method is simple and easy to use, and the addition of sodium-ion-containing substances such as sodium carbonate in noodle preparation is reduced so that the prepared noodles are healthy and better in quality.
