Linolenic acid health care edible oil, Chinese prickly ash seed meal and preparation method thereof

Abstract

The invention discloses a linolenic acid health care edible oil, Chinese prickly ash seed meal and a preparation method thereof. The preparation method comprises the following steps: (1) preparing crude oil: picking high quality green prickly ash seeds, rolling the seeds, and extracting crude oil; (2) refining: subjecting the crude oil obtained in the step (1) to hydration degumming, alkali refining (for removing acid), water washing (for removing impurities), dehydration, discoloring, deacidification, and deodorization. The obtained linolenic acid health care edible oil comprises 8 to 15% of palmitic acid, 5 to 15% of palmitoleic acid, 30 to 40% of oleic acid, 20 to 35% of linoleic acid, and 10 to 18% of alpha-linolenic acid. At the same time, Chinese prickly ash seed meal is produced. Through the method mentioned above, the impurities are effectively separated and removed, the color and odor are eliminated; at the same time, the oleic acid value and peroxide value that continuously change during the production process are always controlled so as to produce the linolenic acid health care edible oil that meets the national sanitary standards of edible plant oil; the content of unsaturated fatty acid can reach 80% or more, the linolenic acid content is high, and thus the provided edible oil is very good.

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...

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
