Embodiment Construction

[0015] The present invention will be further described below in conjunction with specific embodiments, so as to help understand the content of the present invention.

[0016] 1. Add 0.5kg of prickly ash seeds with plump kernels and 12.5L of edible grade 6# solvent oil into the extraction tank, put in nitrogen protection, heat to 70°C, and extract for 160 minutes.

[0017] 2. Stand still for 10 minutes, filter and separate the Zanthoxylum bungeanum seeds from the mixed solution, distill the mixed solution under reduced pressure under the protection of nitrogen, and recover the solvent; the Zanthoxylum bungeanum seed skin oil is first removed impurities with a 300-mesh filter cloth while it is hot, and then collected after cooling down.

[0018] 3. Repeat the operation steps and conditions in 1 and 2 for the Zanthoxylum bungeanum and solvent recovered in step 2, recycle the solvent, and collect a total of 0.047kg of Zanthoxylum bungeanum oil.

[0019] 4. Crush the Zanthoxylum bu...

Abstract

The invention discloses an extraction process of pepper seed oil. The husk oil and the kernel oil of pepper seed are extracted through a same solvent two-step extraction method, which effectively avoids the problems that pepper seed husk and kernel can not be separated throughly, raw materials are easily lost, etc., realizes the separate extraction of the pepper seed husk oil and kernel oil, and improves the utilization value of the husk oil and the quality of the kernel oil. The kernel oil extracted through the method can be used as edible oil after being refined and the husk oil can be used as industrial oil, which effectively solves the problems of low oil yielding rate, poor quality of kernel oil products, etc. of the prior art.

Description

technical field [0001] The invention relates to a technology for extracting pepper seed oil, in particular to a technology for extracting pepper seed skin oil and kernel oil by a two-step extraction method with the same solvent. Background technique [0002] Zanthoxylum bungeanum Maxim belongs to Rutaceae (Rutaceae) perennial shrubs or small trees. It has been cultivated in my country for more than 2,000 years and is one of the traditional "eight seasonings" in my country. Zanthoxylum bungeanum seed is the main by-product in the production of Zanthoxylum bungeanum peel, and Zanthoxylum bungeanum peel accounts for 40% by mass, and seed accounts for about 60%. The particle size of Zanthoxylum bungeanum seed is about 3.5-4.0 mm, the thousand-grain weight is 12.5-22.0 g, and the skin and kernel account for 30% and 70% of the whole seed weight respectively. The oil content in the whole seed of Zanthoxylum bungeanum is 27-31%, of which the skin oil is 6%, and the kernel oil is 20...
