Description

A kind of lemon vinegar and preparation method thereof
Technical field
The present invention relates to a kind of lemon vinegar and preparation method thereof, belong to field of health care food.
Background technology
The long history of vinegar, ancients begin to vinegar very early.Generally, China thinks that vinegar starts to be made at the Western Zhou Dynasty.Food Vinegar, also known as vinegar, vinegar, Bitters etc., are a kind of liquid tart flavour flavorings commonly used in cooking.The main nutrient composition of acetic acid includes Lactic acid, a variety of organic acids, several mineral materials etc..Its primary efficacy whets the appetite, and promotes digestion, reduces blood pressure, and reduces blood fat, Soften blood vessel etc..
Lemon vinegar is as a kind of acid health care condiment, and it not only has seasoning, and improve a poor appetite and promote the function of digesting, Also rich in abundant vitamin, mineral matter, the nutritional ingredient such as amino acid, with the guarantor such as antibacterial, sterilization, antifatigue, beauty, fat-reducing Effect is good for, therefore lemon vinegar is loved by people.
But be due to lemon have higher acidity, with high bottom acid fruit juice carry out acetic fermentation, with fermentation time length, Quality is unstable, the low shortcoming of conversion ratio;And in the preparation process of lemon vinegar, the bitter substance (example in lemon can be caused Such as, limonin, aurantiin etc.) produce, such as it can cause the precursor of limonin in the conventional fermentation process for prepare vinegar Compound decomposes to produce limonin, and it can also be seen that lemon for universal from lemon vinegar product evaluation in the market Lemon vinegar has higher bitter taste, so as to significantly impact the popularization of lemon vinegar.
The content of the invention
An object of the present invention is to provide acetic acid, the 1- for containing 2-8% (w/v) in a kind of lemon vinegar, the lemon vinegar The amino of 6% (w/v) citric acid, the limonin less than 0.05%, the Nomilin acid less than 0.05% and 0.1-2% Acid.
In one embodiment, in the lemon vinegar containing 4-6% (w/v) acetic acid, 2-3% (w/v) citric acid, The amino acid of limonin less than 0.02%, the acid of the Nomilin less than 0.02% and 0.9-1.5%.
The second object of the present invention is to provide the preparation method of the lemon vinegar, comprises the following steps that:
1) take natural lemon to carry out clean, stripping and slicing, lemon juice magma is obtained by squeezing;
2) pectase and brown sugar are added into lemon juice magma and is stirred, fermentation is added into the lemon juice of mixing Flora is fermented at room temperature, and the alcohol concentration of tunning terminates fermentation when reaching 12~14 degree;
3) access acetobacter into zymotic fluid to be fermented again under the conditions of 20~30 DEG C, until the wine of tunning Smart volume fraction terminates fermentation when being less than 0.2%, then through ageing is that lemon vinegar is made.
In one embodiment, in step 2) in, content of the pectase in zymotic fluid is 0.5-2% (w/v), brown sugar Content in zymotic fluid is 5-15% (w/v).
In scheme is further carried out, content of the pectase in zymotic fluid is 0.7-1.5% (w/v), and brown sugar is in hair Content in zymotic fluid is 8-12% (w/v).
In another embodiment, the fermentative microflora is made up of saccharomycete, lactic acid bacteria and monascus ruber, three kinds of bacterium Concrete content of the group in zymotic fluid is 0.1-1% (w/v) saccharomycete, 0.1-1% (w/v) lactic acid bacterias and 0.1-0.3% (w/ V) Aspergillus.
In a specific embodiment, the fermentative microflora is 0.7% (w/v) saccharomycete, 0.2% (w/v) by content Lactic acid bacteria and 0.1% (w/v) Aspergillus composition.
In still another embodiment, the Aspergillus is monascus.
Because lemon juice has higher acidity, the fermentation efficiency in this meeting extreme influence preparation process, so as to cause hair Ferment time length, quality are unstable, the low shortcoming of conversion ratio.Present invention discover that being added in alcoholic fermentation process after a small amount of Aspergillus Influence of the high bottom acid to fermentation process in zymotic fluid can be overcome, and have been surprisingly found that it can also substantially reduce bitter taste in lemon The generation of material, so that the lemon vinegar obtained has preferably mouthfeel.
Embodiment
Also the present invention further can be understood by embodiment, wherein the embodiment illustrates that some are prepared or user Method.It is to be appreciated, however, that these embodiments do not limit the present invention.The change of the invention of currently known or further exploitation Change is considered within the scope of the invention described herein and claimed below.
In the present invention, unless otherwise indicated, otherwise own " % " and represent w/v, i.e. g/100ml.
Embodiment 1
Take natural lemon to carry out clean, stripping and slicing, lemon juice magma is obtained by squeezing;1% is added into lemon juice magma Pectase and 8% brown sugar stirring mixing, add fermentative microflora and be uniformly mixing to obtain mixing liquid, make in mixing liquid ferment Micro-flora content is 0.7% saccharomycete, 0.2% lactic acid bacteria and 0.1% monascus, and the mixing liquid is sent out at 20 DEG C Ferment, until the alcohol concentration of tunning reaches that 12~14 degree terminate fermentation, and accesses 1% acetobacter (final concentration), Fermented again under the conditions of 20~30 DEG C, until the alcohol by volume fraction of tunning terminates fermentation less than 0.2%, then through old Make and lemon vinegar is made.
Embodiment 2
Take natural lemon to carry out clean, stripping and slicing, lemon juice magma is obtained by squeezing;Added into lemon juice magma 1.5% pectase and the stirring mixing of 10% brown sugar, add fermentative microflora (1% saccharomycete, 0.3% lactic acid bacteria and 0.2% Aspergillus) mixing liquid is uniformly mixing to obtain, the mixing liquid is fermented at 20 DEG C, until the alcohol of tunning Concentration reaches that 12~14 degree terminate fermentation, and accesses 1% acetobacter, is fermented again under the conditions of 20~30 DEG C, directly Alcohol by volume fraction to tunning terminates fermentation less than 0.2%, then through ageing is that lemon vinegar is made.
