Problems solved by technology

The main problem that above-mentioned processing method exists: the one, use supercritical CO 2 The Zanthoxylum bungeanum seed oil produced by the extraction equipment is of good quality, but the equipment investment is large and the production cost is high; the second is to use the solvent leaching method to produce the Zanthoxylum bungeanum seed oil, the large-scale leaching equipment has the problems of large equipment investment and insufficient raw material supply, and the small-scale leaching equipment has the problem of desolvation It is difficult to meet the standard; the third is that the peeling effect of pepper seeds is not ideal, and the cost of peeling is relatively high; the fourth is that the traditional alkali refining deacidification method is used, the refining consumption is too large, and the product yield is low

Embodiment 1

[0020] Weigh 20 kg of cleaned pepper seeds, crush them into particles larger than 6 mesh and smaller than 60 mesh with a pulverizer, fry in an electric frying pan at a constant temperature of 100°C for 20 minutes, and use an oil press to obtain an acid value of 42mgkoH / 5.20 kilograms of crude oil of 100g, this crude oil is heated up to 80 ℃ earlier, then dewaxed under 5-6 ℃ environment, obtains 4.26 kilograms of dewaxed crude oil, 0.94 kilogram of by-product wax. Add 4.26 kg of dewaxed crude oil to 12.78 kg of 70% edible alcohol (the volume ratio of ethanol to water in the alcohol is 70:30); stir at room temperature for 60 minutes (extraction temperature usually does not exceed 50°C) , and then left to stand for 60 minutes to form upper and lower liquid phases. The supernatant liquid reclaims 12.2 kilograms of alcohol by atmospheric pressure evaporation to obtain 0.38 kilograms of free fatty acid concentrate; the lower floor liquid is oil, with a weight of 3.88 kilograms and ...

Embodiment 2

[0022] Weigh 20 kg of cleaned pepper seeds, crush them into particles larger than 10 mesh and smaller than 40 mesh with a pulverizer, put them into a frying pan, fry at a constant temperature of 110°C for 15 minutes, and use an oil press to obtain an acid value of 45.2mgkoH / 100g 5.1 kilograms of crude oil, this crude oil is dewaxed under the environment of 5-6 ℃, obtains 4.15 kilograms of dewaxed crude oils, 0.95 kilograms of by-product waxes. Add 4.15 kg of dewaxed crude oil into 10.37 kg of acetone, stir at 15°C for 20-30 minutes at room temperature, and then let stand for 40 minutes to form upper and lower layers. Supernatant liquid reclaims 9.53 kilograms of acetones by atmospheric pressure evaporation, obtains 0.41 kilograms of free fatty acid concentrates; Lower floor liquid is 3.74 kilograms of oils and fats of acid value 12.2mgkoH / 100g, adds alkali and deacidification, soapstock separation, water washing according to conventional methods, Dry at 75°C for 40 minutes und...

Embodiment 3

[0024] After cleaning 20 kg of Zanthoxylum bungeanum seeds, use a grinder to crush them into particles larger than or equal to 10 mesh and smaller than 20 mesh, pour them into an electric frying pan, fry at a constant temperature of 130°C for 10 minutes, and use an oil press to obtain an acid value of 46.1mgkoH 5.32 kilograms of crude oil per 100g, this crude oil is heated up to 60 ℃ earlier, then dewaxed under 4-5 ℃ environment, obtains 4.34 kilograms of dewaxed crude oil, 0.98 kilogram of by-product wax. 4.34 kg of dewaxed crude oil was added to 8.68 kg of ethanol with a volume concentration of 95%, stirred at 30°C for 40 minutes, and then left to stand for 30 minutes to form upper and lower layers of liquid, which were separated to obtain upper and lower layers of liquid. The supernatant liquid reclaims 8.42 kilograms of alcohol through atmospheric pressure evaporation to obtain 0.45 kilograms of free fatty acid concentrate; the lower floor liquid is 3.89 kilograms of grease...

Abstract

The invention discloses a method for producing pepper seed oil, mainly comprising the steps of crushing pepper seeds, frying seeds, expelling, dewaxing, extracting low-polarity organic solvent, processing extraction liquid on the upper and lower layers, wherein the upper layer is recycled by recovering organic solvent; the material obtained from concentration is free fatty acid; the lower-layer liquid is grease with low acid value, drying, decolouring and filtering at low temperature by a regular refining process to obtain the qualified oil product with the acid value within the range of national standard. In the invention, the pepper seed skin and kernel are expelled together, the crude oil contains a great amount of alpha-linolenic acid in the kernel and volatile oil in the skin, the crude oil is firstly dewaxed and then a great amount of free fatty acid is extracted with the organic solvent, then alkaline refining is performed, the yield of the product is improved, the additional value of the secondary product of wax and the free fatty acid is high, and the loss of volatile oil and oxidization of alpha-linolenic acid are reduced via the low-temperature refining process. The produced pepper seed oil contains above 30 percent of the alpha-linolenic acid and has intense spicy smell. The invention ensures that the pepper seed is comprehensively processed and utilized.

Description

technical field [0001] The invention relates to the technical field of preparation of edible oil, in particular to a production method of prickly ash seed oil. Background technique [0002] Zanthoxylum bungeanum belongs to the perennial shrub or small tree of Rutaceae, and it is one of the eight traditional seasonings in my country. Zanthoxylum bungeanum is a by-product in the production of Zanthoxylum bungeanum peel. It is reported that the annual output in my country is about 1.3 million tons. Zanthoxylum bungeanum contains more than 20% crude fat, of which the content of α-linolenic acid is more than 30%. Zanthoxylum bungeanum skin contains a large amount of volatile essential oil. Zanthoxylum bungeanum oil is a kind of high nutritional value and characteristic seasoning oil. However, due to the high acid value and high wax content of Zanthoxylum bungeanum seed oil, it is difficult to process and utilize it. The existing processing technology of Zanthoxylum bungeanum se...
