Problems solved by technology

But so far, the application of Zanthoxylum bungeanum is only widely used for medicinal and seasoning purposes, and only a small amount of red Zanthoxylum bungeanum seeds are obtained by local methods, but the oil is black in color, rich in impurities, high in acid value, and unstable. , easy to oxidize, the acid value is particularly easy to rise, the decolorization is complicated, and the refining is difficult. It can only be used as industrial oil, and it is far from reaching the edible standard. Hundreds of thousands of tons
[0003] The oil content of green pepper seeds is low. Although the oil content of green pepper seeds with high maturity has increased to a certain extent, and the content of linolenic acid is also high, it affects the harvest of green pepper shells, and the loss outweighs the gains; the crude oil of green pepper seeds with insufficient maturity The acid value is extremely high, the oil content is low, and the linolenic acid content is also extremely low, so it has no utilization value

Embodiment Construction

[0012] The production process of linolenic acid health edible oil mainly adopts the general equipment of the edible oil industry, and the specific preparation method is divided into the following steps:

[0013] 1. Preparation of Zanthoxylum bungeanum oil

[0014] a. Raw material selection, flaking

[0015] The green pepper seeds with suitable maturity of the year were selected as the raw material for extracting linolenic acid health edible oil. It has been proved by many tests that when the oil content of the fruiting green pepper seeds reaches about 15%, the acid value of the crude oil is below 20, which can take into account the utilization value of the pepper seeds and shells and reduce the loss.

[0016] The dried and clean green pepper seeds (water content below 11%) are put into a flaking machine, and flaked to 0.1-0.5mm flakes for later use. The pretreatment is not only simple in process, but also beneficial to the subsequent crude oil leaching.

Abstract

A method for the preparation of edible oil rich in linolenic acid and the cake of zanthoxy lum seed, includes the steps: (1)preparing crude oil, includes choosing fresh zanthoxy lum seed, rolling seed kernel, leaching out oil; (2)refining, includes hydration degumming, deacidifing by adding alkali, washing away impurity, dehydrating, decolouring and deodouring. Said oil comprises: palmic acid 8-15%, palmitoleic acid 5-15%, oleic acid 30-40%, linolic acid 20-35%, alpha-linolenic acid 10-18%. The cake of zanthoxy lum seed is produced at the same time. Said method can control oil acid value and peroxide value and said oil has health-care function.

Description

technical field [0001] The invention relates to a method for refining linolenic acid health-care edible oil, in particular to a method for refining linolenic acid health-care edible oil from green pepper seeds. Background technique [0002] Zanthoxylum bungeanum belongs to the Rutaceae plant, which is an important economic tree species in my country. It is a treasure all over the body. Although the oil content of Zanthoxylum bungeanum is lower than that of tea seeds and rapeseeds in oil crops, the oil content of Zanthoxylum bungeanum is 27% to 34%. Green Zanthoxylum bungeanum seed oil contains 12% to 20%, but the unsaturated fatty acid content in Zanthoxylum bungeanum seed oil is extremely high, reaching more than 85%, and the content of linolenic acid is as high as 12-24%, which is much higher than that of tea oil, olive oil and soybean oil. Sexual oil, and linolenic acid has the functions of significantly lowering blood lipids, regulating blood pressure, improving cardiovasc...
