Embodiment 1

[0019] Select 50kg of undegummed oil sample, heat the oil to 75°C, add 40% citric acid for acid reaction, adjust the pH value to 5, and mix ultrasonically for 20 minutes; then cool down to 40°C, add sodium alginate - Chitosan immobilized enzyme granules with phospholipase A2 and phospholipase C at a ratio of 1:3, added in an amount of 50g (the amount of immobilized enzyme loaded is 1.0g / g carrier), mixed evenly, and the ultrasonic power was 80W , the intermittent ultrasonic time is 10 minutes, stop for 10 minutes in the middle of intermittent operation (i.e. ultrasonic for 10 minutes, stop for 10 minutes, then ultrasonic for 10 minutes, and stop for 10 minutes), react for 1h10min, and then centrifuge at 7000 rpm to remove immobilized Enzyme granules, then heat the centrifuged degummed oil to 70°C, add 5% hot salt water (sodium chloride solution), the hot salt water accounts for 0.2% of the oil weight, stir evenly, and centrifugal dehydration (centrifuge speed is 5000 rpm ), to...

Embodiment 2

[0021] Select 50kg of undegummed oil sample, heat the oil to 80°C, add 45% citric acid for acid reaction, adjust the pH value to 6, and mix ultrasonically for 30 minutes; then cool down to 50°C, add sodium alginate - Chitosan-immobilized phospholipase A2 and phospholipase C granules with a ratio of 1:4, the amount added is 90g (the amount of immobilized enzyme loaded is 0.3g / g carrier), mixed evenly, and the ultrasonic power is 160W , the intermittent time is 20 minutes, stop for 20 minutes in the middle of intermittent operation (that is, ultrasonic for 20 minutes, stop for 20 minutes, then ultrasonic for 20 minutes, and stop for 20 minutes), react for 2h20min, and then centrifuge (centrifuge speed is 7000 rpm), Remove the immobilized enzyme particles, then heat the centrifuged oil to 80°C, add 7% hot salt water (sodium chloride solution), the hot salt water accounts for 0.2% of the oil weight, stir evenly, and centrifuge for dehydration (the speed of the centrifuge is 5000 rp...

Embodiment 3

[0023] Select 50kg of undegummed oil sample, heat the oil to 85°C, add 50% citric acid for acid reaction, adjust the pH value to 4, and mix ultrasonically for 10 minutes; then cool down to 60°C, add sodium alginate - Chitosan-immobilized phospholipase A2 and phospholipase C granules with a ratio of 1:5, the addition amount is 150g (the enzyme loading of immobilized enzyme is 0.1g / g carrier), mix well, and the ultrasonic power is 240W , the intermittent time is 30 minutes, stop for 30 minutes in the middle of intermittent operation (that is, ultrasonic for 30 minutes, stop for 30 minutes, then ultrasonic for 30 minutes, and stop for 30 minutes), react for 3h30min, and then centrifuge (centrifuge speed is 7000 rpm), Remove the immobilized enzyme particles, then heat the centrifuged oil to 90°C, add 9% hot salt water, the hot salt water accounts for 0.3% of the oil weight, stir evenly, and centrifuge for dehydration (the speed of the centrifuge is 5000 rpm) to obtain Degummed oil...

Abstract

The invention belongs to the field of food processing, and particularly relates to an efficient enzymatic degumming process for edible oil. The efficient enzymatic degumming process for the edible oilcomprises the following steps: heating edible oil which is not degummed, adding a citric acid buffer solution to adjust the pH value, ultrasonically mixing uniformly, and standing; pouring the oil into an enzyme reaction tank, adding a composite immobilized phospholipase solution into the oil, and carrying out intermittent ultrasonic mixing; and then centrifuging, hydrating, degumming and centrifuging. According to the method, phospholipid in oil can be effectively removed so as to increase the refining rate, and the immobilized compound enzyme can be recycled and reused so as to reduce the cost, so that the economic benefits of enterprises are increased, the environmental pollution is reduced, and the method has a relatively good popularization value.

Description

technical field [0001] The invention belongs to the technical field of edible oil processing, and in particular relates to an efficient enzymatic degumming process of edible oil. Background technique [0002] Oil refining usually refers to the refining of crude oil. The impurities in crude oil not only affect the edible value and safe storage of oil, but also bring difficulties to deep processing, but refining does not remove all impurities in oil. Instead, remove harmful and unhelpful impurities such as gossypol, protein, phospholipids, mucus, water, etc., which are harmful to food, storage, and industrial production, while beneficial impurities such as vitamin E and sterols must be retained. Oil refining process includes: oil degumming, oil deacidification, oil decolorization, oil deodorization, oil dewaxing. [0003] Oil degumming is a crucial process in oil refining. Impurities such as phospholipids, proteins, mucus, and glycosyl diglycerides contained in crude oil are ...
