Problems solved by technology

[0003] The ripe pressing method of walnut oil is to heat and ripen the walnuts and then use the oil press to physically squeeze them. However, this method is difficult to ripen. If the temperature is too high, it is easy to cause the local temperature of the walnuts to be too high, resulting in burnt walnuts, which seriously affects the quality of the walnuts. Oil quality; if the temperature is too low, the walnuts will not be fully ripened, which will affect the oil yield

Abstract

The invention relates to walnut oil curing squeezing method which specifically comprises the following steps: (1) purchasing and crushing high-quality walnut kernels; (2) performing curing treatment on walnut kernels; and (3) removing impurities of walnut oil. Tests show that by adopting the walnut oil curing squeezing method provided by the invention, moisture and impurities such as coked walnutkernels generated in the curing squeezing process are reduced, the content of impurities in crude oil is reduced to be less than 1.0% from 2.1% of the prior art, meanwhile the oil yield of the walnutkernels is increased to be 39.9% or greater from 38.5% of the prior art, and thus the economic benefits of companies are greatly increased.

Description

technical field [0001] The invention belongs to the technical field of edible oil or fat, and in particular relates to a method for ripely squeezed walnut oil. Background technique [0002] Walnut oil is a vegetable oil obtained by pressing walnut kernels as raw materials. Belongs to edible oil. The oil content of walnut is as high as 65%-70%, ranking first among all woody oils, and has the reputation of "oil depot on trees". Using modern technology to extract its essence, this is a new generation of walnut product - walnut oil. Walnut oil is a natural fruit juice made from high-quality walnuts as raw materials and using international leading technology. In the international market, walnut oil is known as "Oriental olive oil" and is favored by consumers just like olive oil. [0003] The ripe pressing method of walnut oil is to heat and ripen the walnuts and then use the oil press to physically squeeze them. However, this method is difficult to ripen. If the temperature i...
