Embodiment 1

[0015] Embodiment 1: a kind of method of producing glacial acetic acid with potato, concrete steps are as follows:

[0016] 1. Selection of potatoes and initial processing: Select fresh, mildew-free potatoes harvested in the year, wash off the sediment in flowing water, peel off the outer skin, and cut into 0.5 square cubes of diced potatoes.

[0017] 2. Cooking: Put the diced potatoes into the steamer, add water according to 2 / 3 of the weight of the diced potatoes, turn on the mixer and steamer to cook and sterilize, 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% liquefying 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. Starch is completely converted to glucose.

[0019] 4. Fermentation and alcoholization: move the liquefied material into a suction filter for suction filtra...

Embodiment 2

[0022] Embodiment 2: a kind of method with potato production glacial acetic acid, comprises following procedure:

[0023] 1. Selection of potatoes and initial processing: Select fresh, mildew-free potatoes harvested in the year, wash off the sediment in flowing water, peel off the outer skin, and cut into 0.8 square cubes of diced potatoes.

[0024] 2. Cooking: Put the diced potatoes into the steamer, add water according to 2 / 3 of the weight of the diced potatoes, turn on the mixer and steamer to cook and sterilize, 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% liquefaction 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. Starch is completely converted to glucose.

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.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a method for producing glacial acetic acid, especially a method for producing glacial acetic acid from potatoes, belonging to the technical field of food processing. Background technique [0002] Glacial acetic acid is anhydrous acetic acid, which can be used as acidity regulator, acidulant, pickling agent, flavor enhancer, spice, etc. It is also a good antimicrobial agent. It is the earliest and most used sour agent in my country. It is mainly used in compound seasoning, wax preparation, canned food, cheese, jelly, etc. [0003] Most of the raw materials used to produce glacial acetic acid are grains, the production cost is high, and the process is complicated, so the price is expensive and the product is in short supply. Contents of the invention [0004] Purpose of the invention: the purpose of the present invention is to provide a method for producing glacial acetic acid fro...
