preparation example Construction

[0014] The preparation method of the seal oil microcapsule provided by the embodiment of the present invention adopts sodium alginate, sodium caseinate, calcium lactate, maltodextrin, modified soybean protein isolate and slow-release calcium hydroxide powder as embedding materials, and the The purified seal oil is embedded layer by layer to form multi-shell microcapsules with a high embedding rate, which can well isolate the seal oil from the air and avoid its oxidative deterioration during processing, transportation, and consumption. It prolongs its shelf life; and compared with the traditional spray drying method, the temperature is lower, so the quality of seal oil can be better guaranteed, and the production cost is saved; in addition, the addition of slow-release calcium hydroxide powder can improve the The effect of microcapsule products being digested and absorbed by the human body, thereby improving the absorption rate of seal oil by the human body, so that the seal oil...

Embodiment 1

[0046] The preparation technology of the seal oil microcapsules of embodiment 1 is as follows:

[0047] The subcutaneous fat tissue excised from the anatomical tissue of the seal is immediately frozen, and then the frozen subcutaneous fat tissue is taken out and cut into pieces, and then the cut subcutaneous fat tissue is placed in a twister at a temperature of 0°C. Crush and grind in a meat machine, and apply mechanical pressure to squeeze the oil out of the fat tissue, centrifuge at 3500rpm for 15 minutes, collect the oil—the crude extract of seal oil, and then place the crude extract of seal oil at an operating pressure of 2Pa, The temperature is 100°C and vacuum distillation is carried out to obtain purified seal oil.

[0048] The purified seal oil was dispersed in a compound solution of sodium alginate and sodium caseinate 10 times its volume, and homogenized at 800 r / min for 10 min to obtain seal oil microcapsules. Among them, the compound solution of sodium alginate an...

Embodiment 2

[0052] The preparation technology of the seal oil microcapsules of embodiment 2 is as follows:

[0053] The subcutaneous fat tissue excised from the anatomical tissue of the seal is immediately frozen, and then the frozen subcutaneous fat tissue is taken out and cut into pieces, and then the cut subcutaneous fat tissue is placed in a twister at a temperature of 5°C. Crush and grind in a meat machine, apply mechanical pressure to squeeze the oil out of the fat tissue, centrifuge at 4000rpm for 10min, collect the oil—the crude extract of seal oil, and then place the crude extract of seal oil at an operating pressure of 8Pa, The temperature is 60° C. and vacuum distillation is carried out to obtain purified seal oil.

[0054] The purified seal oil was dispersed in a compound solution of sodium alginate and sodium caseinate three times its volume, and homogenized at 1000 r / min for 5 minutes to obtain seal oil microcapsules. Among them, the compound solution of sodium alginate and...

Abstract

The invention is applicable to the technical field of pharmaceutical and chemical industry, and provides a seal oil microcapsule and a preparation method thereof. The method comprises the steps that sodium alginate, sodium caseinate, calcium lactate, maltodextrin, modified soy isolate protein and slow-release calcium hydroxide powder are adopted as embedding materials, seal oil subjected to purification treatment is embedded layer by layer, and the microcapsule with multiple shell layers is formed, so that the embedding rate is high, the seal oil can be well isolated from air, oxidative deterioration of the seal oil in the processing, transporting and consuming processes is avoided, and the shelf life of the seal oil is prolonged; compared with a traditional spray drying mode, the temperature is lower, so that the quality of the seal oil can be better ensured, and the production cost is saved; and besides, by adding the slow-release calcium hydroxide powder, the effect of digesting andabsorbing the microcapsule product by the human body can be improved, so that the absorption rate of the human body to the seal oil is improved, and the seal oil can better exert the nutritional andmedical values.

Description

technical field [0001] The invention belongs to the technical field of medicine and chemical industry, and in particular relates to a seal oil microcapsule and a preparation method thereof. Background technique [0002] Seal oil is made from seal oil by low-temperature pressing. It is rich in polyunsaturated fatty acids and squalene, among which omega-3 unsaturated fatty acids - DHA (docosahexaenoic acid), EPA (eicosapentaenoic acid), DPA (docosapentaenoic acid) has the functions of improving nervous system function, improving intelligence and brain, protecting eyesight, preventing myocardial and cerebral infarction, lowering blood fat, inhibiting tumor growth, anti-inflammation, inhibiting It has functions such as allergic reactions, so it has extremely high nutritional and medical value. [0003] These polyunsaturated fatty acids are easily oxidized, and the oxidized polyunsaturated fatty acids not only lose their nutritional and medical value, but also tend to produce un...
