Problems solved by technology

In the existing micro-aerobic fermentation equipment, the stirring temperature control device and the stirring device are designed separately, occupying a limited volume of the fermentation tank, and the effective utilization rate of the machine is low; at the same time, the oxygen supply equipment is directly connected to the fermentation tank, so it is difficult to control the fermentation The oxygen content in the tank cannot effectively control the degree of microbial fermentation

Abstract

The invention discloses a method for brewing cucumber vinegar by micro-aerobic fermentation technology, which comprises the following steps: (1) freezing treatment; (2) enzymatic hydrolysis; (3) component adjustment; (4) pasteurization; (5) alcohol Fermentation; (6) Acetic acid fermentation: put the fermented liquid into another oxygen-controlled fermenter, add acetic acid bacteria to carry out microaerobic fermentation; in the early stage of fermentation, the growth of bacteria is relatively slow, and the temperature and oxygen flow of fermentation are controlled; in the middle stage of fermentation, Acetic acid bacteria multiply rapidly and require a large amount of oxygen consumption. Control the fermentation temperature at 28-34°C; in the later stage of fermentation, the amount of acetic acid bacteria begins to decline slowly, and keep the fermentation temperature at 26-30°C; (7) Blending, filtering and bottle storage. The present invention can make full use of cucumber raw materials. By using the oxygen-controlled fermentation tank invented by our team for micro-aerobic fermentation, it can be brewed into high-quality cucumber vinegar with bright color, strong cucumber aroma, no precipitation, round taste and richness, which has a wide market promotion value.

Description

【Technical field】 [0001] The invention relates to the field of utilization and processing of cucumbers, in particular to a method for brewing cucumber vinegar by adopting micro-aerobic fermentation technology. 【Background technique】 [0002] As an indispensable acid condiment in people's daily life, vinegar also has multiple nutritional and health care functions and medical value in addition to its seasoning function. Traditional vinegar brewing is brewed from rice, glutinous rice, corn, sorghum and other starches as main raw materials, which not only consumes a lot of food, but also cannot meet people's increasingly higher requirements for nutrition, flavor, and taste. At the same time, my country's fruit and vegetable production ranks among the top in the world, but due to reasons such as sales lag and fresh-keeping technology, fruits and vegetables suffer serious losses in the circulation process, with a loss rate as high as 30%. Processing fruits and vegetables into ace...
