The method for testing the rice-yarn elastic coefficient in the embodiment comprises the following steps: the method comprises selecting 10 rice noodles with uniform thickness and no cracks, cutting into 15 cm long, boiling in 300 mL boiling distilled water until white heart disappears, measuring one rice noodle each time, and performing other shear tests. And when the tensile test is carried out, winding the parallel friction roller for 2-3 circles to prevent any sliding. The measurement Force in Tension mode, the test probe: A/SPR; the speed before the test is 1 mm/s, the speed after the test is 1 mm/s and the speed after the test is 10 mm/s; initial distance: 40 mm; and (3) testing distance: 80 mm; data acquisition rate: 100 Hz. Tensile strength (N/mm2) = maximum tensile force/meter cross-sectional area of wire; tensile set (%) = meter-line tensile extension distance/meter-line original length.
The cooking loss rate in this example was measured by weighing 100g (m 1) of dry rice noodles, weighing 500mL of water (m2), cooking 100g of rice noodles in water for 5min, taking out the rice noodles, cooling to room temperature, adding 500mL of water, weighing again (m 3), calculating the cooking loss rate of rice noodles according to the following formula, Y = (m3-m2)/m1 × 100%,
in this embodiment, the method for detecting the broken rate of the meter line comprises the following steps: placing rice noodle in an electrothermal blowing drying oven, drying until the water content is below 14%, selecting 20 samples with length of 20 cm, steaming in 500mL boiling water for 2min, taking out the rice noodle samples, draining with supercooled water, and recording the number of rice noodle strips with length of more than 10 cm as X1.
