Embodiment 1

[0022] A processing method of a product rich in grape seed polyphenols, comprising the steps of:

[0023] 1) Adjust the gap between the grinding roller and the grinding plate of the disc mill to 6mm;

[0024] 2) select the grape seeds of varieties such as Cabernet Sauvignon or Merlot with a water content of 12wt% as raw materials, put the grape seeds into the disc mill for peeling, control the feeding amount of the grape seeds to be 200g / min, control the disc mill The rotation speed of the machine is 1200rpm. After the grape seeds are ground by the cavity of the disc mill under the action of their own weight, the mixture of the outer skin and inner seeds is obtained. After the mixture is sieved, the outer skin and inner layer of the grape seeds are obtained. The outer skin is rich in grape seeds. Products of polyphenols.

Embodiment 2

[0026] A processing method of a product rich in grape seed polyphenols, comprising the steps of:

[0027] 1) Adjust the gap between the grinding roller and the grinding plate of the disc mill to 8mm;

[0028] 2) select the grape seed that the moisture content is 6wt% for use as a raw material, put the grape seed into the disc mill and peel the grape seed, control the feeding amount of the grape seed to be 250g / min, control the disc The speed of the mill is 1000rpm. After the grape seeds are ground by the cavity of the disc mill under the action of their own weight, the mixture of the outer skin and inner seeds is obtained. After the mixture is sieved, the outer skin and inner layer of the grape seeds are obtained. The outer skin is rich in Products of grape seed polyphenols.

Embodiment 3

[0030] A processing method of a product rich in grape seed polyphenols, comprising the steps of:

[0031] 1) Adjust the gap between the grinding roller and the grinding plate of the disc mill to 10mm;

[0032] 2) select the grape seed that the water content is 10wt% Zizhenxiang variety as raw material, put grape seed into disc mill and carry out dehulling, control the feeding amount of grape seed to be 300g / min, control the rotating speed of disc mill to be 1400rpm, the grape seeds are ground by the cavity of the disc mill under the action of their own weight to obtain a mixture of the outer skin and inner seeds. After the mixture is sieved, the grape seed outer skin and inner layer are obtained. The outer skin is a product rich in grape seed polyphenols .

[0033] The products obtained in Examples 1-3 and the amounts of the inner layers are shown in Table 1.

[0034] The grape seed skin of table 1 embodiment 1~3 gained and the amount of inner layer respectively

Abstract

The invention relates to a processing method of a product rich in grape seed polyphenol. The processing method comprises the following steps of (1) adjusting the gap between a grinding roller grindingbody and a grinding sheet of a disk type grinding machine according to the particle size of grape seeds; and (2) putting the grape seeds into the disk type grinding machine for peeling, after grinding of the grape seeds is completed by a cavity of the disk type grinding machine under the effect of self weight of the grape seeds, obtaining a mixture of outer peel and internal seeds, and sieving the mixture to obtain grape seed outer peel and inner layers, wherein the grape seed outer peel is the product rich in grape seed polyphenol. The content of the grape seed polyphenol in the grape seed outer peel product obtained by the processing method disclosed by the invention is very high, after the processing method is applied to the extraction course of the grape seed polyphenol, the separation efficiency is greatly improved, and the resource reuse of grape seeds is well realized.

Description

technical field [0001] The invention relates to a method for separating natural products, in particular to a method for separating products rich in grape seed polyphenols from grape seeds, and belongs to the technical field of food processing. Background technique [0002] The total area of ​​grape planting in my country is as high as 720,000 hectares, with a total output of 11.38 million tons, of which more than 1 million tons are used to produce wine. Based on this calculation, the grape seeds produced by brewing wine are about tens of thousands of tons every year. The current common practice is to directly dump or simply use it as feed or fertilizer, which is not only inefficient and wasteful, but also brings greater environmental pollution. [0003] Grape seeds contain a variety of active ingredients. Grape seeds contain 14% to 17% of oil, of which linoleic acid accounts for 68% to 76%. In addition, grape seeds are also rich in polyphenols, mainly proanthocyanidins, whit...
