Description
Technical field:
The present invention relates to a kind of method of rapeseed oil being carried out refining.
Background technology:
Coming unstuck is a important step in the rapeseed oil refining process, is the necessary condition that guarantees that physical refining carries out smoothly, most important to improving refining yield and oil quality.Colloid removes not thorough, has both influenced the deep processing of oil product and the stability of oil product, also influences the cooking consumption of oil product.The main purpose of coming unstuck is the phosphatide that removes in the oil, and phosphatide divides hydrated phospholipid and nonhydratable phosphatide, in degumming tech, hydrated phospholipid can be removed by the method for simple hydration degum, nonhydratable phosphatide has obvious hydrophobic, difficulty combines with water in hydration degum, removes comparatively difficulty.Because the factor of rapeseed maturity period climatic influences and rapeseed maturity, and reason such as technological operation control in the production and processing, often make to have more nonhydratable phosphatide in mao vegetable seed, traditional aquation technology can't be removed, and this has just influenced the quality of product oil.
Development through decades, particularly physical refining successful implementation, people have released multiple Degumming method, as utilize that traditional hydration degum, simple acid system come unstuck, Special comes unstuck and enzyme method for degumming etc., the enzyme method for degumming is a new and high technology of oil and fat refining, and this technology has huge using value aspect economic benefit that improves oil prodution industry and the environmental-protecting performance.The enzyme method for degumming can drop to phosphorus content in the oil below the 10mg/kg, but the existence of free phosphorus lipase costs an arm and a leg, and is difficult for reclaiming problems such as catalyzing hydrolysis condition harshness.
Summary of the invention
The present invention is wayward and cause the high problem of phosphatidase cost in enzyme deactivation and the enzymatic degumming in order to solve in the actual production enzyme reaction condition, and has proposed to use immobilized phospholipase A
1The refining vegetable seed crude oil.Use immobilized phospholipase A
1The refining vegetable seed crude oil is realized by following steps: one, 1.0~15g sodium alginate is dissolved in 50~500g distilled water standby, with 5~50mL phospholipase A
1Join 50~500mL, pH value and be among 5 the HAc-NaAc or citric acid solution, it is standby to obtain enzyme liquid; Two, be that 0.5~3: 1 ratio is mixed with sodium alginate soln and enzyme liquid with volume ratio, obtain mixed liquor; Three, 1.0~15g shitosan is dissolved in 2~10% acetums of 50~500g, joins the CaCl of 0.05~0.2mol/L of preparation 100~1000mL again
2In the solution, mixed liquor is dropwise joined CaCl
2In the mixed solution, form circular granular, particle left standstill under 30~50 ℃ condition, dry after 40~60 minutes, the graininess immobilised enzymes is standby; Four, get the vegetable seed crude oil hydrated phospholipid in hydration degum method removal vegetable seed crude oil earlier, the citric acid solution that add mass concentration then and be 40~50% in treated vegetable seed crude oil, quality is vegetable seed crude oil 0.1~2% also stirred 5~30 minutes with 500~1500 rev/mins speed, added mass concentration again and be 4% NaOH solution in treated vegetable seed crude oil and constantly stir until the pH of vegetable seed crude oil value to stop to add NaOH solution between 4.0~6.0; Five, in the vegetable seed crude oil of adjusting the pH value, be incorporated as 0.05~0.5% immobilised enzymes of the vegetable seed quality of crude oil of adjusting the pH value under 45~60 ℃ of conditions; Six, the vegetable seed crude oil that the adds immobilised enzymes speed with 40~100r/min was stirred 2~12 hours, then to the vegetable seed crude oil that adds immobilised enzymes centrifugal 1~5 minute with the speed of 6000~8000r/min, remove the impurity in the heavy phase, promptly realize with immobilized phospholipase refining vegetable seed crude oil.
Phospholipase A in the method for refining vegetable seed crude oil of the present invention after the immobilization
1Hear resistance be improved, can in the pH of broad scope, keep higher activity, the sensitiveness of reaction environment is reduced, make easier control of operating condition and enforcement.Phospholipase A after the immobilization
1But more than the successive reaction 25h, can also recycle and reuse, improved the efficient of coming unstuck, improved 5~30% than existing method, reduce production costs, cost has reduced by 20~40% than existing method, but the high long-time continuous of the present invention's stability is operated, the retentive activity height, up to 50~80%, the present invention can carry out the large-scale industry operation.
