Embodiment 1

[0045] 1 g of Sn-1,3-position specific lipase 435 lipase, 1 g of sodium hydroxide, 10 g of diatomaceous earth, and 10 g of alumina were weighed, and then added to the chromatography column after physical mixing. Take 1kg of edible soybean oil and carry out the above-mentioned mixed packing column chromatography column operation, the column temperature is controlled at 50±2°C, the pressure is controlled at 0.04±0.02mPa, and the column passing time is 10h. The acid value, methoxyaniline value, peroxide value and stearic acid content of edible soybean oil and post-column refined soybean oil were detected. The measurement results are shown in Table 1 (wherein, the acid value, peroxide value and methoxyaniline value were measured and calculated according to the method shown in the Pharmacopoeia).

Embodiment 2

[0050] 10 g of Sn-1,3-position-specific lipase Lipase lipase, 10 g of sodium hydroxide, 50 g of diatomaceous earth, and 50 g of silica gel were weighed, and then added to a chromatography column after physical mixing. Take 1 kg of edible soybean oil, and carry out the above-mentioned mixed packing column chromatography column operation. The acid value, methoxyaniline value, peroxide value and stearic acid content of edible soybean oil and post-column refined soybean oil were detected. The measurement results are shown in Table 2 (wherein, the acid value, peroxide value and methoxyaniline value were measured and calculated according to the method shown in the Pharmacopoeia).

Embodiment 3

[0054] 100 g of Sn-1,3-specific lipase RMIM lipase, 100 g of calcium hydroxide, 50 g of bentonite, and 750 g of white clay were weighed, and then added to a chromatography column after thorough physical mixing. Take 5kg of edible soybean oil and pass it through a mixed packing chromatography column. The acid value, methoxyaniline value, peroxide value and stearic acid content of edible soybean oil and post-column refined soybean oil were detected. The measurement results are shown in Table 3 (wherein, the acid value, peroxide value and methoxyaniline value were measured and calculated according to the method shown in the Pharmacopoeia).

Abstract

The invention belongs to the technical field of medicinal oil refining, and discloses a method for accurately controlling the content of stearic acid in soybean oil by using a mixed filler. The methodcomprises the following steps: A. physically and uniformly mixing lipase, inorganic base, a filter aid and an adsorbent to form a mixed filler, the lipase being Sn-1, 3-site specific lipase; B, enabling soybean oil to flow through the mixed filler to obtain refined soybean oil. The method solves the problems that the stearic acid content cannot be accurately controlled and the requirement for preparing a high-quality fat emulsion preparation cannot be met in the traditional soybean oil production process.

Description

technical field [0001] The invention relates to the technical field of medicinal oils and fats refining, in particular to a method for accurately controlling the content of stearic acid in soybean oil by using mixed fillers. Background technique [0002] There are a small amount of free fatty acids and a large amount of bound fatty acids in oil. Among them, free fatty acids are easier to remove and control, but bound fatty acids are in the form of esters as one of the components of oils and fats, which often cannot be removed and controlled. As for the raw material itself, its composition ratio is natural and random. [0003] Soybean oil is a natural oil extracted and refined from soybean. It is the main energy component of parenteral nutrition fat emulsion injection and the oil phase matrix of drug-loaded fat emulsion. Soybean oil can provide essential fatty acids for the human body, and its main fatty acids include palmitic acid, palmitoleic acid, stearic acid, oleic acid...
