Problems solved by technology

The traditional water substitution process is: clearing kernels, moistening kernels, frying kernels, raising smoke, blending pulp and stirring oil, shaking and separating oil, etc. The walnut oil produced has a rich and soft flavor, but it is labor intensive and produces a lot of waste water And can not achieve continuous production, development is restricted
The machine-pressing process developed later includes steps such as cleaning kernels, frying kernels, raising smoke, tempering, squeezing, filtering, and sedimentation. Although it makes up for the shortcomings of the water substitution method, it has the advantages of a high degree of self-control and continuous production. The flavor of the walnut oil produced has no water substitution method, and the walnut oil is soft and pure
Most of the traditional walnut oil production process is to produce walnut oil after roasting, roasting and pressing at high temperature. The nutritional components and active substances of the produced oil will be lost, and the oil production rate and oil quality will be affected. Its natural The fresh scent will also be affected

Abstract

The invention discloses a processing method for producing walnut oil. The processing method comprises the steps of airing, grinding, heat preservation, cake preparation, stewing, squeezing and filtering and specially comprises the steps of taking shelled walnut kernels; airing the shelled walnut kernels to obtain dried walnut kernels; grinding in a grinder, sealing the ground walnut kernels in a container, and carrying out heat preservation at the temperature of 55+/-5 DEG C for 2 hours; preparing cakes, putting the cakes in a food steamer for stewing by virtue of vapor; and after stewing, squeezing to obtain crude walnut oil; and precipitating the crude walnut oil for 36-48 hours and then filtering to obtain finished walnut oil. According to the invention, the walnut oil is intense and soft in taste, is beneficial to body health if used for a long time due to high monounsaturated fatty acid, and has high nutritive value and health effect.

Description

technical field [0001] The invention relates to a processing method of edible oil, in particular to a processing method for producing walnut oil with walnut kernels as raw materials.
