Preparation process of water-soluble peony seed oil powder

Abstract

The peony seed oil is rich in a great amount of unsaturated fattyacid, alpha-linolenic acid with maximal content in the peony seed oil is essential to the human body and has an important effect on improving the intelligence, protecting the vision and preventing cardiovascular and cerebrovascular diseases. But a majority of unsaturated fattyacid is easily oxidized, and the nutritional value of the peony seed oil is reduced. A preparation process of the water-soluble peony seed oil powder comprises the following steps of dissolving a wall material and an emulsifier into distilled water, stirring the wall material, the emulsifier and the distilled water until being adequately dissolved, slowly adding the peony seed oil to carry out the embedding at the temperature of 30 to 90 DEG C according to the ratio of the peony seed oil to the wall material of 1: 10 to 5: 10, adequately mixing the solution, homogenizing and emulsifying the mixture under the pressure condition of 100 to 1000 bar to obtain an emulsified solution, and carrying out spray drying or freezing drying on the emulsified solution, thus preparing the water-soluble peony seed oil powder product. The water-soluble powder product has the advantages that the oxidation of the peony seed oil can be prevented, convenience in carrying can be realized and the like, and after the water-soluble peony seed oil powder is added into the drinking water, a stable emulsion system with good dispersion can be formed. The water-soluble powder can be used as a mate for the drink such as coffee, contains no trans-fatty acids and is safe and nutritional.

Description

technical field [0001] The invention relates to a preparation process of peony seed oil deep-processing product. technical background [0002] Peony (Paeonia suffruticosa Andr.) is a deciduous shrub belonging to Ranunculaceae. It is widely distributed in Luoyang, Henan, Heze, Shandong, Tongling, Anhui, Hanzhong, Shaanxi, Baishan, Hebei, Sichuan, Gansu, Zhejiang and other places. The planting area has reached 300,000 mu, and the annual output of peony seeds is about 30,000 tons. [0003] Peony seed oil was approved by the Ministry of Health as a new resource food in 2011. The oil yield of peony seeds is more than 25%, of which the unsaturated fatty acid content is more than 80%. Peony seed oil contains a large amount of linolenic acid and linoleic acid needed by the human body. The content of α-linolenic acid can be as high as 42.34%. It is an essential fatty acid for the human body and plays an important role in enhancing intelligence, protecting eyesight and preventing car...

Problems solved by technology

Both of these two edible forms have problems such as inconvenient to carry, difficult to store the product for a long time, and relatively narrow application range.

The peony seed oil in the liquid state is harmful to O because of its high content of unsaturated fatty acids such as α-linolenic acid. 2 , ultraviolet rays, high temperature and metal ions are very sensitive. In the process of processing and storage, it is easy to oxidize and rancid, resulting in a decline in the quality of oils and fats. Usually, it needs to be kept away from light and stored at low temperature; although products in the form of soft capsules can isolate oil from oxygen, But it can only be taken orally directly, which is not conducive to mixing with other foods as a nutritious food. The wide range of applications is limited, and it is more sensitive to temperature. When the temperature is around 40°C, oil leakage will occur, and it cannot be used well. guaranteed quality
