Abstract

The invention discloses a method for producing glacial acetic acid with potatoes and belongs to the technology of food processing. The method specifically includes six steps of potato selection and primary processing, cooking, liquidation, fermentation and alcoholizing, acetic fermentation and reduced pressure distillation. Shortcomings that the glacial acetic acid is high in production cost and complex in process are effectively overcome. The method has the advantages that the glacial acetic acid is produced through the potatoes instead of grain, production cost is lowered, simpleness in the process is achieved, content of potassium of the produced glacial acetic acid is 25 times higher than that of rice vinegar, content of lysine, valine and phenylalanine is 2-3 times higher than that of the rice vinegar, and nutrient value is prior to the glacial acetic acid produced from the grain.

Example Embodiment

[0015] Example 1: A method for producing glacial acetic acid from potatoes, the specific steps are as follows:
[0016] 1. Choose potatoes and initial processing: Choose fresh, mildew-free potatoes harvested that year, remove the mud and sand in the flowing water, remove the outer skin, and cut into 0.5 cube potato cubes.
[0017] 2. Steaming: Put the diced potato into the steamer, add water according to 2/3 of the weight of the diced potato, turn on the blender and steam engine for cooking and sterilization, and keep the temperature at 130°C for 40 minutes.
[0018] 3. Liquefaction: When the temperature of the steamer drops to 60°C, add 0.8% liquefied enzyme and continue to stir. When the material changes from paste to liquid, control the temperature at 55°C, add 1.2% glucoamylase and keep it warm for 2 hours. The starch is completely converted to glucose.
[0019] 4. Fermentation and alcoholization: Move the liquefied material into a suction filter and pump the filtrate into the fermentation tank, add 1.8% alcohol yeast, turn on the mixer, keep the temperature at 48℃, and the alcohol fermentation time is 70 hours.
[0020] 5. Acetic acid fermentation: Connect 1.8% acetic acid bacteria in the fermentation material, keep the insulation at 50°C, ferment for 65 hours, then take out the pot and then move it into the suction filter for suction filtration, and collect the filtrate to become a semi-finished product.
[0021] 6. Vacuum distillation: Distill the semi-finished product under reduced pressure, evaporate and concentrate the water to obtain the finished product of glacial acetic acid.

Example Embodiment

[0022] Example 2: A method for producing glacial acetic acid from potatoes, including the following procedures:
[0023] 1. Choose potatoes and initial processing: Choose fresh, mildew-free potatoes harvested that year, remove the sediment in the flowing water, trim off the outer skin, and cut into 0.8 square diced potatoes.
[0024] 2. Steaming: Put the diced potato into the steamer, add water according to 2/3 of the weight of the diced potato, turn on the blender and steam engine for cooking and sterilization, and keep the temperature at 140°C for 35 minutes.
[0025] 3. Liquefaction: When the temperature of the steamer drops to 65°C, add 0.8% liquefied enzyme and continue to stir. When the material changes from paste to liquid, control the temperature at 58°C, add 1.2% glucoamylase and keep it warm for 2 hours. The starch is completely converted to glucose.
[0026] 4. Fermentation and alcoholization: Move the liquefied material into a suction filter, and pump the filtrate into the fermentation tank, add 1.8% alcohol yeast, turn on the mixer, keep the temperature at 50℃, and the alcohol fermentation time is 65 hours.
[0027] 5. Acetic acid fermentation: Connect 1.8% acetic acid bacteria in the fermentation material, keep the spacer at 52℃, ferment for 60 hours, then take out the pot, then move it into the suction filter for suction filtration, and collect the filtrate to become a semi-finished product.
[0028] 6. Vacuum distillation: Distill the semi-finished product under reduced pressure, evaporate and concentrate the water to obtain the finished product of glacial acetic acid.
