Embodiment 1

[0040] Weigh 5g of Sn-1, 3-position-specific lipase Lipase lipase, 10g of sodium hydroxide, 50g of diatomaceous earth, and 50g of silica gel, mix them uniformly physically, and add them to the chromatographic column, such as figure 1 -A shown. Take 1 kg of edible soybean oil, and carry out the operation of the above-mentioned mixed packing column chromatography, the column temperature is controlled at 45±2°C, the pressure is controlled at 0.2±0.02mPa, and the contact time is 4h. The acid value, methoxyaniline value, peroxide value and stearic acid content of soybean oil before and after refining were detected. The measurement results are shown in Table 1 (wherein, the acid value, peroxide value, and methoxyaniline value are measured and calculated according to the methods shown in the Pharmacopoeia).

Embodiment 2

[0045] Weigh 150 g of Sn-1, 3-position specific lipase RMIM lipase, 180 g of sodium hydroxide, 100 g of diatomaceous earth, and 100 g of silica gel, mix them uniformly physically, and add them to the chromatographic column, such as figure 1 -A shown. Take 2kg of virgin olive oil, and carry out the operation of the above-mentioned mixed packing column chromatography, the column temperature is controlled at 55±2°C, the pressure is controlled at 0.1±0.02mPa, the time for passing through the column is 12h, and the number of cycles is 1. Detect the acid value, methoxyaniline value, peroxide value and palmitic acid content of olive oil before and after refining. The measurement results are shown in Table 2 (wherein, the acid value, peroxide value, and methoxyaniline value are measured and calculated according to the methods shown in the Pharmacopoeia).

Embodiment 3

[0049] Weigh 50g of Sn-1, 3-position-specific lipase 435 lipase, 100g of potassium hydroxide, 300g of bentonite, and 300g of clay, and add them to the chromatography column through physical mixing, such as figure 1 -A shown. Take 3 kg of edible sesame oil and pass it through a mixed packing chromatography column. The column temperature is controlled at 50±2°C, the pressure is controlled at 0.2±0.02mPa, and the time for passing the column is 8h. Detect the acid value, methoxyaniline value, peroxide value and palmitic acid content before and after refining. The measurement results are shown in Table 3 (wherein, the acid value, peroxide value, and methoxyaniline value are measured and calculated according to the methods shown in the Pharmacopoeia).

Abstract

The invention belongs to the technical field of refiningof medicinal oil, and discloses a method for accurately controlling the proportion of specific fatty acid in oil by adopting a microcirculationtechnology. The method comprises the following steps: A, uniformly mixing lipase, inorganic base, a filter aid and an adsorbent in a physical mode to form a mixed filler, wherein the lipase is Sn-1,3-specific lipase; and B, enabling edible oil to flow through the mixed filler to obtain refined oil. The method solves the problems that the content of palmitic acid cannot be accurately controlled andthe requirement for preparing a high-quality fat emulsion preparation cannot be met in a traditional edible oil production process.

Description

technical field [0001] The invention relates to the technical field of medicinal oil refining, in particular to a method for precisely controlling the proportion of specific fatty acids in oil by using microcirculation technology. Background technique [0002] Medicinal oil is an important raw material for fat emulsion preparations, and it is also an energy source for fat emulsion preparations to provide nutritional support. Oils and fats for injection are divided into plant sources and animal sources, and the types and contents of fatty acids in triglycerides of oils and fats from different sources are very different. According to the different nutritional needs of clinical patients, fat emulsion preparations with different nutritional compositions have appeared on the market. However, regardless of plant or animal origin, the vast majority of oils for injection are derived from natural products, and their composition is complex. The traditional oil refining process mainly...
