Processing method of prickly ash seed kernel oil

Abstract

The invention discloses a processing method of prickly ash seed kernel oil. The method comprises the following steps of: step 1, crushing dried prickly ash seeds into a particle material, sorting out black seed shells and white seed kernels from the particle material by adopting a material sorting machine, and squeezing seed kernel particles and collecting prickly ash seed kernel oil; step 2, adding ethyl alcohol-sodium hydroxide solution mixed liquid which is 1-2 times of the weight of crude oil into crude oil, stirring for 1-3 hours at a temperature 25-60 DEG C, then standing for 1-3 hours, layering, and separating out an oil phase on the upper layer; and step 3, heating the oil phase to 40-60 DEG C, dehydrating, then decolorizing by usingkieselguhr, filtering and deodorizing, thereby obtaining the prickly ash seed kernel oil. The processing method is capable of separating out shells and internal kernels of prickly ash seeds, respectively squeezing and soaking to obtain edible prickly ash kernel oil and prickly ash seed husk oil. The method is low in cost, high in operability and high in oil yield; the obtained prickly ash seed kernel oil is low in gelatine and waxiness contents and low in solvent residual.

Description

technical field [0001] The invention relates to the field of oil processing, in particular to a method for processing prickly ash seed oil. Background technique [0002] Zanthoxylum bungeanum seeds are the leftovers from the production of Zanthoxylum bungeanum, which is 20% more than the peel in theory, and the actual annual output is equal to that of Zanthoxylum bungeanum. In the past, people mostly used Zanthoxylum bungeanum seeds as fertilizer or discarded them, and some units also used traditional oil-making techniques to extract Zanthoxylum bungeanum oil. However, the simple processed Zanthoxylum bungeanum seed oil is tan or black, with an acid value as high as 38-65 (KOH) / (mg / g), easy to crystallize, has a pungent smell, poor taste, cannot be eaten, and can only be processed by chemical methods Into high acid value industrial oil, its price and sales are restricted. In the past, the whole seed was directly crushed and extracted to obtain the mixed oil of skin oil and...
