CN106148149A - A kind of grape skin brewages the production technology of grape fruit vinegar - Google Patents

Abstract

The invention discloses a kind of grape skin and brewage the production technology of grape fruit vinegar, specifically comprise the following steps that after making grape wine that remaining scrap leather slag dries in the shade after 1h, put into 55 DEG C of drying in oven, size-reduced machine is crushed to 20 mesh；95% edible ethanol dilute is become 45% alcohol concentration, and the skin slag after pulverizing adds in 45% concentration ethanol, extracts 6h under the water bath condition of 60 DEG C；Adding water and adjust lixiviating solution alcohol concentration to 8%, then in the lixiviating solution after adjusting, the addition white sugar of mass fraction 8%, the acetic acid bacteria of 15% carry out acetic fermentation, and fermentation temperature is 35 DEG C；The grape skin fermented is carried out sucking filtration, obtains filtrate fill；By canned filtrate at 80 DEG C of pasteurization 30min, after cooling, i.e. obtain grape fruit vinegar.The present invention utilizes discarded grape skin for raw material, largely avoided the waste of resource, reduces the load to environment, the fruit vinegar bright color that simultaneously prepares, nutritious.

Description

A kind of grape skin brewages the production technology of grape fruit vinegar

Technical field

The present invention relates to a kind of grape skin and brewage the production technology of grape fruit vinegar, be applied to Fructus Vitis viniferae reprocessing technology neck Territory.

Background technology

Rich in abundant vitamin, mineral and flavonoid in Fructus Vitis viniferae, wherein flavonoid is a kind of powerful antioxidants, can Defying age, and interior free yl can be removed；Simultaneously possibly together with a kind of anticancer trace element in Fructus Vitis viniferae, healthy cell cancer can be prevented Become, prevent cancerous cell from spreading, it can be seen that Fructus Vitis viniferae has the highest nutritive value；In the market, occur much producing Portugal The producer of grape wine, produces the grape skin of many after wine machines, and these skin slag parts are by quilt after roughing As feedstuff, Fertilizer application, also have the biggest part to be simply discarded, bring the biggest load to environment, waste simultaneously A lot of resources.

Summary of the invention

For solving above-mentioned problem, the invention discloses a kind of grape skin and brewage the production technology of grape fruit vinegar, tool Body step is as follows:

Step one: after remaining scrap leather slag dries in the shade 1h after making grape wine, putting into 55 DEG C of drying in oven, size-reduced machine is pulverized To 20 mesh；

Step 2: 95% edible ethanol dilute is become 45% alcohol concentration, it is dense that the skin slag after pulverizing in step one adds 45% In degree ethanol, wherein skin slag is 1:7(g/ml with the solid-liquid ratio of ethanol), under the water bath condition of 60 DEG C, extract 6h；

Step 3: add water and adjust the lixiviating solution alcohol concentration of gained in step 2 to 8%, then in the lixiviating solution after adjusting Add the white sugar of mass fraction 8%, the acetic acid bacteria of 15% carries out acetic fermentation, and fermentation temperature is 35 DEG C；

Step 4: the grape skin fermented is carried out sucking filtration, obtains filtrate fill；

Step 5: by canned filtrate at 80 DEG C of pasteurization 30min, i.e. obtains grape fruit vinegar after cooling.

Use the technical program, the invention has the beneficial effects as follows: utilizing discarded grape skin is raw material, largely avoided The waste of resource, reduces the load to environment, the fruit vinegar bright color that simultaneously prepares, nutritious.

Detailed description of the invention

The invention discloses a kind of grape skin and brewage the production technology of grape fruit vinegar, specifically comprise the following steps that

Step one: after remaining scrap leather slag dries in the shade 1h after making grape wine, putting into 55 DEG C of drying in oven, size-reduced machine is pulverized To 20 mesh；

Step 2: 95% edible ethanol dilute is become 45% alcohol concentration, it is dense that the skin slag after pulverizing in step one adds 45% In degree ethanol, wherein skin slag is 1:7(g/ml with the solid-liquid ratio of ethanol), under the water bath condition of 60 DEG C, extract 6h；

Step 3: add water and adjust the lixiviating solution alcohol concentration of gained in step 2 to 8%, then in the lixiviating solution after adjusting Add the white sugar of mass fraction 8%, the acetic acid bacteria of 15% carries out acetic fermentation, and fermentation temperature is 35 DEG C；

Step 4: the grape skin fermented is carried out sucking filtration, obtains filtrate fill；

Step 5: by canned filtrate at 80 DEG C of pasteurization 30min, i.e. obtains grape fruit vinegar after cooling.

Last it is noted that above example only in order to the present invention is described and and unrestricted technology described in the invention Scheme；Therefore, although this specification with reference to each above-mentioned embodiment to present invention has been detailed description, but, this Field it is to be appreciated by one skilled in the art that still the present invention can be modified or equivalent；And all are without departing from this The technical scheme of the spirit and scope of invention and improvement thereof, it all should be contained in scope of the presently claimed invention.
