Embodiment example 1

[0023] [Implementation case 1] Determination of the eutectic point of shrimp

[0024] The state in which the solute and water are both frozen is a eutectic, and the freezing temperature is the eutectic point, which can be determined by the resistance method. In the process of gradually heating up the shrimp from the frozen state, the resistance in the shrimp will gradually decrease, and when the eutectic point is reached, the resistance will change suddenly. Freeze 200g of shrimp in a -80°C refrigerator for 2 to 3 hours, take out the frozen shrimp, make it warm up gradually, and observe the change of its resistance value. Through the above experiments, it is found that when the temperature of the shrimp increases to -20~-25°C, the resistance value of the shrimp changes suddenly, so it is determined that the eutectic point of the shrimp is at -20~-25°C.

[0025] [Implementation Case 2] Preparation of Spicy Instant Shrimp Snack Food

[0026] Shell the fresh macrobrachium, take out the whole shrimp, wash 3 times to ensure that the shrimp is clean, put the cleaned shrimp on the sieve to drain, after the water is drained, put it in 95-100 ℃ hot water to mature for 2-5 minutes , take it out, drain the water to the fullest, weigh 1KG and put it into the spicy-flavored seasoning for mixing.

[0027] The formula of spicy flavor seasoning is: salt 1.2%, monosodium glutamate 0.4%, chicken essence 0.4%, I+G 0.008%, chili oil 4%, pepper oil 0.24%, acetic acid 0.02%, potassium sorbate 0.03%. The weight of shrimp is 1 (100%).

[0028] The mixed shrimps were put into the vacuum freeze-drying equipment, and the shrimps were freeze-dried through three stages of pre-freezing, sublimation drying and analytical drying, and a total of 238.6g of spicy instant shrimp snack food was obtained.
