Production technology process of raw virgin high-oleic-acid peanut oil

Abstract

The invention discloses a production technology process of raw virgin high-oleic-acid peanut oil, and belongs to the field of peanut oil extraction. The production technology process of the raw virginhigh-oleic-acid peanut oil comprises the following steps of 1, selection of raw materials, wherein peanuts with the oleic acid content of 75% or above are selected; 2, magnetic separation, wherein metal impurities in the peanut raw materials are removed by magnetic separation equipment; 3, cleaning of the raw materials, wherein high-quality peanut kernel raw materials are selected and put, then afan and a vibrating screen are adopted for dust, stone and impurity removal, and the full peanut raw materials at the grade of 3 or above and without breakage are selected out through magnetic separation for impurity removal, screening and grading. Rotten and deteriorated peanuts are removed through ultraviolet light irradiation and color selection, the high-quality peanut raw materials are selected, aflatoxin in the peanut raw materials is reduced, and the quality of the peanut oil is improved; by adopting a technology for removing the aflatoxin of the peanut kernels through ozone and ultraviolet light irradiation, the content of the aflatoxin B1 in the peanut oil is further reduced to 0.1 microgram / kg or below, and the high-end quality of the peanut oil is achieved.

Description

technical field [0001] The invention relates to the technical field of peanut oil extraction, in particular to a production technology of raw virgin high oleic peanut oil. Background technique [0002] Peanut is an important oil crop and economic crop in China, and my country is also the largest consumer and exporter of peanut. Peanut is one of the three largest oil crops in China and one of the top five oil crops in the world. It is also the oil crop with the highest total output. With the improvement of people's life quality, consumers prefer healthy edible oils, and restaurant chefs pay more attention to food with better flavor. Peanut oil has become a more preferred choice for consumers. China used to be a big exporter of peanuts, but now it is gradually becoming a big importer. [0003] Oleic acid is a monounsaturated fatty acid, which is called "safe fatty acid" by the nutritional circles, and is rich in peanuts and olives. The quality of high oleic peanut oil is com...

Problems solved by technology

[0008] In view of the problems existing in the prior art, the object of the present invention is to provide a production technology of raw virgin high oleic peanut oil, which has the advantages of high-quality peanut oil, avoiding the loss of nutrients, and reducing the content of benzopyrene and aflatoxin , to solve the process of crushing and producing peanut oil, often due to improper process, the fragrance is reduced or changed, the quality of peanut oil is low, and it also causes a large loss of natural nutrients (such as vitamin E, phytosterol, squalene, etc.), which is serious The nutritional and safety quality of peanut oil is reduced, and the existing technology mostly uses high-temperature pressing, which results in serious pollution of harmful substances. The content of plasticizers, benzopyrene and aflatoxin in peanut oil is relatively high, causing potential safety hazards.
