Problems solved by technology

[0003] At present, the preparation of peony seed oil is mostly made by traditional pressing technology combined with degumming, deacidification, decolorization, and deodorization processes, but the oil yield of this process is not high, especially the extraction of linoleic acid and linolenic acid The rate is low, resulting in low utilization rate of nutrients in peony seeds

Embodiment 1

[0029] A production process of peony seed oil, comprising the following steps:

[0030] (1) Peony seeds are peeled from the peony pods, dried for 6-12 hours under the condition of vacuum degree of 0.08~0.09MPa negative pressure and temperature of 23~26°C, and then crushed into peony seed powder , the water mass content of peony seed powder is 9~10%;

[0031] (2) Put the dried peony seed powder into a Soxhlet extraction device, add a mixture of extraction agents ethyl acetate, ethanol and petroleum ether, the volume ratio of ethyl acetate, ethanol and petroleum ether is 1:3: 8. The liquid-solid ratio of the mixture of ethyl acetate, ethanol and petroleum ether to the peony seed powder is 12ml / g, soak for 2 hours, and then extract at a temperature of 92°C for 2 hours to obtain a crude extract containing peony seed oil liquid;

[0032] (3) concentrating the crude extract containing peony seed oil under reduced pressure, recovering ethyl acetate, ethanol and petroleum ether, and...

Abstract

The invention discloses a technology for producing peony seed oil. The technology includes the following steps that firstly, low-temperature drying is conducted; secondly, dried peony seed powder is placed into a soxhlet extraction device, and a mixed solution of an extraction agent ethyl acetate, alcohol and petroleum ether is added for extraction; thirdly, vacuum concentration is conducted, ethyl acetate, alcohol and petroleum ether are recycled; fourthly, filtering is carried out through an oil filter, and solid residues are separated out; fifthly, deacidification is conducted; sixthly, decoloration is carried out; seventhly, deodorization is conducted. By means of the technology, the oil extraction rate of peony seeds can be effectively increased, the content of linoleic acid and linolenic acid in the peony seed oil is also increased, and accordingly the utilization rate of nutrients in the peony seeds is increased.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a production process of peony seed oil. Background technique [0002] Peony is a plant of the family Ranunculaceae and the genus Paeoniae. It is a small perennial deciduous shrub. There are many varieties of peony, among which peony for oil has ornamental value, and its fruit peony seeds can also be used to make peony seed oil; peony seed oil is a treasure among vegetable oils because of its rich nutrition and unique medical and health care functions. Known as "liquid gold", peony seed oil is the most suitable oil for human nutrition among the oils found so far. It has the highest total nutritional value and the most reasonable composition structure of all edible oils. It is rich in polyunsaturated fatty acids. The value far exceeds 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 ind...
