Problems solved by technology
[0004] From a domestic perspective, the current situation is still not optimistic
Straw returning to the field will affect the growth of crops, straw incineration will pollute the atmospheric environment, and comprehensive development and utilization will face the dilemma of immature technology, relatively large investment and relatively poor effect
[0005] However, there are seldom reports of using corn stalks to make vinegar at home and abroad.

Embodiment Construction
[0022] The method for making vinegar from corn stalks comprises the following steps:
[0023] (1) Raw material processing:
[0024] Mix the main material (corn flour), auxiliary material (bran) and filling material (corn stalk powder) in a ratio of 1:1:1.2, steam the material in a rotary steamer: steam pressure 0.15Mpa, keep for 10-30min, do not stew material. When the quality of the clinker reaches a fresh color, clinker aroma, uniform looseness, non-stickiness, no raw heart, no peculiar smell, and when the water accounts for 42%-28%, add high-activity dry yeast and glucoamylase for saccharification, because the corn stalk powder It has good water absorption and slurry mixing performance, and it can be taken out of the pan to cool after 2 hours.
[0025] (2) Preparation of fermented grains and acetic acid seeds:
[0026] Stir glucoamylase into the cooled mixed steamed clinker, inoculate yeast, add water, and mix evenly to make solid fermented grains.
[0027] Select purel...

The invention relates to a method for preparing vinegar by corn straw, aiming to provide the method for preparing the vinegar by the corn straw, and the method can enrich the comprehensive development and utilization of the corn straw. The purpose of the invention is realized by the following technical scheme that the method for preparing the vinegar by the corn straw comprises the following steps: (1) processing raw materials; (2) preparing fermented grains and vinegar fermented grains; (3) carrying out alcoholic fermentation; (4) carrying out acetic fermentation; (5) pouring vinegar; and (6) sterilizing. The method has the beneficial effects that the corn straw serves as filler to prepare the vinegar, and cellulose in the straw is decomposed by the action of a microbial composite enzymeand is converted into a sugar material which can be fermented and utilized, thereby improving yield, and improving the thick and sweet taste of the vinegar.
Description
technical field [0001] The invention relates to a method for making vinegar from corn stalks. Background technique [0002] In recent years, crop straw has become a new source of rural non-point source pollution. Every autumn and winter, there is always a large amount of corn stalks burned in the field, which produces a lot of thick smoke, which not only becomes the bottleneck of rural environmental protection, but even becomes the chief culprit that affects the urban environment. According to relevant statistics, my country, as a large agricultural country, can produce more than 700 million tons of straw every year, which becomes "waste" that is "not very useful" but must be disposed of. In this case, a large number of incineration occurred. [0003] From the perspective of foreign countries, especially in developed countries, through scientific and technological progress and innovation, a variety of uses have been found for the comprehensive development and utilization o...
