Problems solved by technology

Among them, seabuckthorn liquid oil has peculiar smell, and most consumers are difficult to accept direct drinking, which limits its consumption. In addition, seabuckthorn seed oil is rich in unsaturated fatty acids, resulting in poor oxidation stability and prone to oxidation during processing, transportation, and storage. , and further produce peculiar smell, thereby shortening the shelf life and reducing its physiological efficacy; seabuckthorn oil capsules have the feeling of taking medicine when taken, and the experience is poor, and ingredients such as gelatin and glycerin are often added, which will reduce product acceptance
[0004] At present, the main method of delaying oil oxidation is to add antioxidants, such as BHA, BHT, L-ascorbyl palmitate and other synthetic antioxidants, but the use of additives makes the product not meet the clean label requirements, which reduces the competitiveness of the product to a certain extent and consumer acceptance
Oil microencapsulation technology can also be used to improve oil stability and taste. For example, patent CN201610473860.6 discloses a method for preparing solid seabuckthorn oil cyclodextrin inclusion compound by embedding seabuckthorn oil with cyclodextrin, but the index process requires seabuckthorn The oil and cyclodextrin were treated at 80°C for 40 minutes, and the spray drying outlet temperature was as high as 190°C. The high temperature in both steps had adverse effects on the quality of seabuckthorn oil; Gao Yaxin et al. In the evaluation, a preparation method of seabuckthorn seed oil microcapsules was published, which consisted of sodium starch octenyl succinate, sodium caseinate, maltodextrin 5, resistant dextrin, isomaltulose, sodium tripolyphosphate, L -Ascorbyl palmitate is used as wall material or auxiliary material, the overall ingredients of this product are complicated, and many additives are used

Embodiment 1

[0040] (1) Preparation of Seabuckthorn Leaf Extract

[0041] The dried seabuckthorn leaves were crushed and mixed with water according to the ratio of 1g:8mL of solid to liquid, refluxed and extracted at 60°C for 1 hour, and extracted twice in total, the extracts were combined, and the extracts were subjected to ultrafiltration with an ultrafiltration membrane with a molecular weight cut-off of 20,000. Filtration, rotary evaporation and concentration to obtain a concentrated solution, maltodextrin and cyclodextrin (amount ratio of 3g:1g) were added to the concentrated solution according to the ratio of 1g:5mL of solid to liquid, and spray-dried to obtain seabuckthorn leaf extract.

[0042] (2) Preparation of seabuckthorn oil

[0043] The seabuckthorn leaf extract and seabuckthorn seed oil are mixed according to a mass ratio of 1:100, and stirred evenly to obtain seabuckthorn oil with high stability and high antioxidant capacity.

Embodiment 2

[0045] (1) Preparation of Seabuckthorn Leaf Extract

[0046] Mix the crushed dry seabuckthorn leaves with water according to the solid-liquid ratio of 1g:7mL, reflux extraction at 70°C for 0.5h, extract once in total, combine the extracts, and filter the extracts with an ultrafiltration membrane with a molecular weight cut-off of 30,000 Ultrafiltration, rotary evaporation and concentration to obtain a concentrated solution, maltodextrin and cyclodextrin (amount ratio of 4g:1g) were added to the concentrated solution according to a solid-liquid ratio of 1g:4mL, and spray-dried to obtain sea buckthorn leaf extract.

[0047] (2) Preparation of seabuckthorn oil

[0048] The seabuckthorn leaf extract and seabuckthorn fruit oil are mixed according to the mass ratio of 3:100, and stirred evenly to obtain seabuckthorn oil with high stability and high antioxidant capacity.

Embodiment 3

[0050] (1) Preparation of Seabuckthorn Leaf Extract

[0051] The dried seabuckthorn leaves were crushed and mixed with ethanol according to the solid-liquid ratio of 1g:9mL, refluxed and extracted at 50°C for 2h, and extracted 3 times in total, the extracts were combined, and the extracts were subjected to ultrafiltration with an ultrafiltration membrane with a molecular weight cut-off of 50,000. Filtrate, concentrate by rotary evaporation to obtain a concentrated solution, maltodextrin and cyclodextrin (amount ratio of 2g:1g) were added to the concentrated solution according to a solid-liquid ratio of 1g:6mL, and spray-dried to obtain seabuckthorn leaf extract.

[0052] (2) Preparation of seabuckthorn oil

[0053] The seabuckthorn leaf extract and seabuckthorn seed oil are mixed according to a mass ratio of 5:100, and stirred evenly to obtain seabuckthorn oil with high stability and high antioxidant capacity.

Abstract

The invention discloses sea buckthorn oil with high oxidation resistance and high stability, sea buckthorn oil powder and a preparation method thereof, and belongs to the technical field of food processing. The preparation method of the sea buckthorn oil powder comprises the following steps that sea buckthorn leaves are crushed; extracting is carried out; ultrafiltration is carried out; concentrating is carried out; drying is carried out; and the sea buckthorn leaves are added into sea buckthorn oil, are mixed with protein and polysaccharide, are homogenized to obtain sea buckthorn oil, and are subjected to spray drying to obtain the sea buckthorn oil powder. The sea buckthorn oil and sea buckthorn oil powder prepared by the method have high oxidation resistance and high stability, the increase of peroxide value and the like in the oil storage process is remarkably inhibited, the ingredients are simple and natural, and the market acceptability is high.

Description

technical field [0001] The invention relates to seabuckthorn oil with high oxidation resistance and high stability, seabuckthorn oil powder and a preparation method thereof, belonging to the technical field of food processing. Background technique [0002] Seabuckthorn oil is a precious natural oil extracted from seabuckthorn fruits or seeds. It contains a large amount of unsaturated fatty acids, and more than 100 biologically active substances such as flavonoids, vitamins, phytosterols, trace elements and α-tocopherol. A large number of studies have shown that seabuckthorn oil has good effects and can be used to treat hyperlipidemia, obesity and cardiovascular and cerebrovascular diseases, improve intelligence and brain, and promote the growth and development of children. In addition, seabuckthorn oil also has anti-inflammation and promotes tissue healing It can treat wounds, various ulcers and other diseases. Therefore, seabuckthorn seed oil is called "oil gold" in the wo...
