Embodiment 1

[0016] A deacidification extraction method of peony seed oil, first dehulling peony seeds to obtain peony seed kernels, then crushing them to 20 meshes and using supercritical CO 2 The extraction method is carried out, and the extract obtained by extraction is sent to the rectification column for deacidification and degumming treatment, and the extract after deacidification and degumming is separated by the separation tank to obtain the product, and the extract is subjected to deacidification and degumming treatment in the rectification column The specific operation is: fill the rectification column with θ rings, Pall rings or stainless steel corrugated nets as fillers, then adjust the internal pressure to 10MPa, and divide the rectification column into three sections: upper, middle, lower, and carry out Heating to form a temperature gradient, and the temperature from top to bottom is 35°C, 45°C and 50°C in sequence. After rectification, collect most of the colloidal phospholip...

Embodiment 2

[0022] A deacidification extraction method of peony seed oil, first dehulling peony seeds to obtain peony seed kernels, then crushing them to 80 meshes and using supercritical CO 2 The extraction method is carried out, and the extract obtained by extraction is sent to the rectification column for deacidification and degumming treatment, and the extract after deacidification and degumming is separated by the separation tank to obtain the product, and the extract is subjected to deacidification and degumming treatment in the rectification column The specific operation is: fill the Pall ring in the rectification column as a filler, then adjust its internal pressure to 15MPa, divide the rectification column into three sections, the upper, middle and lower sections, and heat the three sections to form a temperature gradient, and The temperature from top to bottom is 40°C, 50°C and 60°C. After rectification, collect most of the colloidal phospholipid impurities from the bottom of the...

Abstract

A peony seed oil deacidification extraction method includes the steps: firstly, crushing peony seed kernels; performing extraction on the crushed peony seed kernels by a supercritical CO2 method; placing obtained extraction liquid into a rectifying column; performing deacidification and degumming treatment on the extraction liquid; separating the extraction liquid after deacidification and degumming treatment by the aid of a separating kettle to obtain peony seed oil. According to the method, the extraction liquid extracted by the supercritical CO2 method is placed into the rectifying column, deacidified and degummed, the rectifying column is divided into three portions and heated by the aid of different temperatures, so that the extraction liquid layers, most colloid phospholipid and impurities are removed, the quality of the peony seed oil is improved, an acid value is reduced, rectified extraction liquid is separated by the separating kettle, and the impurities and the extraction liquid can be separated.

Description

technical field [0001] The invention relates to the field of vegetable oil extraction, in particular to a deacidification extraction method of peony seed oil. Background technique [0002] The peony seed oil extracted from peony seeds is a unique woody nut oil in China. It is rich in nutrients and unique in health care. It is called "the best oil in the world" by relevant experts and is a treasure among vegetable oils. It is also a unique health care edible oil in China. Peony seed oil is the most suitable oil for human nutrition among the oils found so far, and it has the highest nutritional value and the most reasonable composition structure among all edible oils. Peony seed oil is rich in polyunsaturated fatty acids, and its nutritional value far exceeds that of olive oil, which is known as the "oil of human health". The content of linolenic acid is more than 200 times that of olive oil, and many indicators are also higher than other oils It is not easy to oxidize and d...
