Embodiment 1

[0015] Rapeseed oil hydration and dephosphorization obtained oil feet (from Zhejiang Haining Jinzhong Oil Co., Ltd.) as raw material, dehydrated under vacuum at 45°C to a water content of less than 2.0%. Take 1500g of dehydrated rapeseed oil hydration oil foot, add 2700g of acetone, heat and stir at 60°C for 1 hour, let stand for stratification, separate and remove the acetone phase, and obtain dehydrated rapeseed oil hydration oil foot with pre-de-neutral oil, under vacuum at 45°C Recover acetone by distillation to obtain 450 g of product. Take 450 g of dehydrated rapeseed oil that has been de-neutralized beforehand to hydrate the oil foot, add 1125 g of 90% volume concentration of aqueous ethanol, keep stirring at 50°C for 45 minutes, filter and separate, and distill the filtrate under vacuum at 65°C Reclaim ethanol, obtain 325g of rapeseed powdered phospholipid crude product, add 815g of acetone again, insulated and stirred at 60°C for 50 minutes, filter, and distill and rec...

Embodiment 2

[0017] Rapeseed oil obtained by hydration and dephosphorization (from Zhejiang Haining Jinzhong Oil Co., Ltd.) is used as a raw material, and dehydrated at 50° C. under vacuum to a water content below 2.0%. Take 2000g of dehydrated rapeseed oil hydration oil foot, add 4000g of acetone, heat and stir at 55°C for 1 hour and 5 minutes, let it stand for stratification, separate and remove the acetone phase, and obtain the dehydrated rapeseed oil hydration oil foot of pre-removed neutral oil, vacuum Acetone was recovered by distillation at 50° C. to obtain 600 g of product. 600g of dehydrated rapeseed oil hydrated with de-neutralized oil, added 1200g of 95% volume concentration aqueous ethanol, kept stirring at 40°C for 1 hour, filtered and separated, distilled the filtrate under vacuum at 60°C to recover ethanol, and obtained rapeseed powder phospholipid Add 775 g of acetone to 430 g of the crude product, insulate and stir at 50° C. for 1 hour, filter, and distill the filtered sol...

Embodiment 3

[0019] Rapeseed oil hydration and dephosphorization obtained oil bottoms (from Zhejiang Deqingqing City Oil Company) was used as raw material, and dehydrated under vacuum at 55°C to a water content of less than 2.0%. Take 1000g of dehydrated rapeseed oil hydration oil foot, add 2200g of acetone, heat and stir at 75°C for 45 minutes, let it stand for stratification, separate and remove the acetone phase, and obtain the dehydrated rapeseed oil hydration oil foot of pre-removed neutral oil. ℃ of distillation reclaims acetone, obtains 300 gram products and takes the dehydrated rapeseed oil hydration oil foot 300g of pre-removing neutral oil, adds the hydrous ethanol of 80% volume concentration of 1050g, 45 ℃ of insulated stirring 1 hour, filtration separation, filtrate under vacuum 70 Recover ethanol by distillation at ℃ to obtain 210g crude rapeseed powdered phospholipids, then add 460g of acetone, keep stirring at 65℃ for 40 minutes, filter, and distill the filtered solids at 50℃...

Abstract

The invention relates to a powder rape phospholipids and method of manufacturing the same. The aforementioned powder rape phospholipids is produced from oil foot of rapeseed hydratation, with purity higher than 95%, and content of non-lipid impurity lower than 0.3%. The beneficial effect of the invention is: a powder rape phospholipids with purity higher than 95%, and content of non-lipid impurity lower than 0.3%, which is not disclosed at home and abroad at present, and manufacturing method thereof are provided. The product is in powder, wherein content of the rape phospholipids is enhanced 2-4 times, and content of neutral oil is reduced 6-13 times. It is hard to turn rancid, easy for long-term storage, and can be used in a wider field. In comparison with conventional slurry condensed rape phospholipids, content of phospholipids is increased by 60%, acid value is reduced by about 50%. The invention has a greater effect when used as food additive, which is improved in edible security, easy for storage and transportation, suitable for food processing with higher quality requirements, notably increased in economic value added, and incredibly enhanced in utility of rape phospholipids.

Description

(1) Technical field [0001] The invention relates to a powdered rape phospholipid and a production method thereof. (2) Background technology [0002] Rapeseed is one of the oilseeds with the largest output in the world and the most planted oilseed in China, so the rapeseed phospholipid resource is very rich. The utilization of rapeseed phospholipids is currently processed with rapeseed oil refining by-products as raw materials at home and abroad. Because the phospholipid content of rapeseed is lower than that of soybean, it is more difficult to separate and purify. Therefore, the rapeseed phospholipids produced in the field of oil processing so far are all slurry products with low purity. Some products contain about 70% neutral oil. Impurities such as rapeseed powder and silt are of low quality and can only be used as feed. The high-quality rapeseed phospholipid product produced by the prior art has a purity of no more than 70%, contains about 30% of neutral oil and impurit...
