preparation example Construction

[0009] The preparation process of the present invention is as follows

[0010] 1. Cut open the fresh abalone, remove the shell and intestines, and pre-cool at 0-5°C for more than 12 hours;

[0011] 2. Put the pre-cooled abalone in a clean heating tank, add tap water of equal weight to heat, and heat up to 70°C to 80°C to cook;

[0012] 3. Take out the cooked abalone and put it in a pot containing 1% NaHCO 3 In the container of the aqueous solution, the temperature of the water bath is 45°C, and the abalone is taken out until the weight of the abalone is constant;

[0013] 4. Put the abalone prepared in the previous step into a container filled with an aqueous solution of 2‰ HAC (acetic acid), and prepare it in a water bath at a temperature of 45°C. After the abalone has a constant weight, take it out;

[0014] 5. Put the abalone prepared in the previous step into a container filled with ionized water or distilled water, and process it at 0-4°C until the abalone has a constan...

Embodiment 1

[0018] Cut open the fresh abalone, remove the shell and remove the intestines, and then pre-cool the abalone at 0°C for 16 hours; then put the pre-cooled abalone in a clean heating tank, add an equal weight of tap water to heat, and cook until the temperature rises to 75°C; Take out the cooked abalone and put it in a pot filled with 1% NaHCO 3 In the container of the aqueous solution, the temperature of the water bath is 45°C, and the abalones are taken out when the weight is constant; Proceed at a temperature of 45°C until the abalone has a constant weight, then take it out; put the abalone prepared in the previous step into a container filled with distilled water, and process it at 4°C until the abalone has a constant weight, then take it out; Take out the prepared abalone and put it in a freezer at -4°C for pre-freezing, then deep-freeze at a temperature below -20°C; put the frozen samples into a freeze dryer for vacuum freezing, and after the vacuum reaches 80Pa Freeze-dr...

Embodiment 2

[0020] Cut open the fresh abalone, remove the shell and remove the intestines, and then pre-cool the abalone at 4°C for 18 hours; then put the pre-cooled abalone in a clean heating tank, add tap water of equal weight to heat, and raise the temperature to 80°C to cook; Take out the abalone, put it into a glass container with 1% NaOH aqueous solution, and make it under the condition that the temperature of the water bath is 45°C, and take it out when the weight of the abalone is constant; In a container with an aqueous solution of 1‰HAC (acetic acid), prepare it at a water bath temperature of 45°C. Take out the abalone after the weight is constant; put the abalone prepared in the previous step into a container filled with ionized water or distilled water , at 0°C until the abalone has a constant weight and then take it out; take out the prepared abalone and put it in a cold storage at 0°C for pre-freezing, and then deep-freeze. The general freezing temperature is below -20°C; Th...

Abstract

A freeze-dried abalone is prepared from fresh abalone through removing shell and viscera, precooling, boiling in water, immersing in the aqueous solution of alkali and acetic acid and then in ionic water or distilled water, prefreezing, deep freezing and vacuumf reeze-drying. Its advantage is no less of nutrients.

Description

technical field [0001] The invention relates to a method for producing freeze-dried abalone from fresh abalone. technical background [0002] Abalone is very nutritious. According to the analysis of scientists, every 100 grams of abalone meat contains 40 grams of protein, 0.9 grams of fat, 33.7 grams of carbohydrates, 7.9 grams of inorganic salts, and contains more than 20 kinds of amino acids, multivitamins, Baolingsu and so on. Modern medical research shows that cooking with abalone not only has the function of nourishing and strengthening, but also has a very good auxiliary medical effect on people suffering from tuberculosis and lymphatic tuberculosis. Fresh abalone meat also contains Baolingsu, which has a strong inhibitory effect on cancer cells. In addition to treating gynecological cancers, such as cervical cancer and bladder cancer, it also has good curative effects on esophageal cancer, gastric cancer, liver cancer, and skin cancer. According to traditional Chin...
