To make hot and sour powder is inseparable from noodles, the following Shandong hot and sour powder joined to give you a summary of the four commonly used methods to identify the quality of noodles, I hope to help you!
Vermicelli and noodles are silky or strip dry starch products made from beans, potatoes and grains. The quality of vermicelli is determined by the raw materials. The color of fans produced from different raw materials is different.
Among the potato vermicelli noodles, the color of potato powder is white and transparent; the quality of sweet potato powder is white and transparent, but a little dark, generally the sweet potato is light yellow, or brown, with the unique taste of sweet potato powder; cassava starch is generally not used for vermicelli processing, and in some places, in order to reduce costs, it is made by mixing cassava starch and corn starch. As a result, it pretends to be sweet potato powder with good taste, but this kind of noodles is not boiled well.
(2) Organizational status
In order to perceive the toughness and elasticity of noodles, the sensory identification of the tissue state of noodles is carried out by direct observation, and then by bending and bending the hands.
Good noodles - uniform thickness (wide and thin), no drawing, no broken pieces, flexible handle, elasticity, no impurities. Pure potato noodles have irregular arrangement of bubbles.
(3) Odor and Taste
When making the sensory identification of the flavor and taste of the noodles, the samples can be smelled directly, then the noodles can be soaked in hot water for a moment before smelling the odor; the soft noodles can be chewed in the mouth and tasted.
Good noodles - Normal flavor and taste, no odor.
(4) Fire method
Ignite the powder bar with fire, see the flame, smell and identify the residue after burning. Powder noodles with flour or other low-value fillers are liable to produce the stink and smoke of protein burning after burning. Powder noodles with talcum powder or those without refined starch are not easy to burn and the residues are easy to harden granules. The flame of glued noodles is liable to produce crackling sound and accompanied by thick smoke and excessive moisture. It is easy to produce hissing sound.
