Embodiment 1

[0028] A preparation method for compound microencapsulated soybean lecithin powder for animal husbandry, the specific steps are as follows:

[0029] (1) Thoroughly agitate and extract the soybean lecithin oil with ethanol with a concentration of 90% (v / v), the extraction temperature is 30°C, the ratio of ethanol to soybean lecithin oil is 3:1 (ml / g), extract for 30min, and then centrifuge Separate the extract and insoluble matter, and collect the upper extract; repeat the extraction step twice. The acetone insoluble matter of the soybean lecithin oil is more than 55%, and the PC value of phosphatidylcholine is 18%. In order to achieve the purpose of fully stirring and extracting, ultrasonic assisted extraction can be used, the ultrasonic power is 100-150W, and the assisted extraction is 6-10min. The parameters of the centrifuge for centrifuging the extract and insoluble matter are set at 10000-13000 rpm for 15-25 minutes.

[0030] (2) Merge two extracts, carry out vacuum dis...

Embodiment 2

[0034] A preparation method for compound microencapsulated soybean lecithin powder for animal husbandry, the specific steps are as follows:

[0035](1) Thoroughly agitate and extract the soybean lecithin oil with ethanol with a concentration of 90% (v / v), the extraction temperature is 40°C, the ratio of ethanol to soybean lecithin oil is 3:1 (ml / g), extract for 60min, and then centrifuge Separate the extract and insoluble matter, and collect the upper extract; repeat the extraction step twice. The acetone insoluble matter of the soybean lecithin oil is more than 55%, and the PC value of phosphatidylcholine is 18%. Adding 1.5% by weight glass beads with a diameter of 0.9mm as a dispersant in the phospholipid raw material in advance can improve the viscosity characteristics of soybean lecithin oil during stirring, expand the solvent contact area, and improve the lecithin extraction effect. In order to achieve the purpose of fully stirring and extracting, ultrasonic assisted ext...

Embodiment 3

[0040] A preparation method for compound microencapsulated soybean lecithin powder for animal husbandry, the specific steps are as follows:

[0041] (1) Thoroughly agitate and extract the soybean lecithin oil with ethanol with a concentration of 90% (v / v), the extraction temperature is 35°C, the ratio of ethanol to soybean lecithin oil is 3:1 (ml / g), extract for 40min, and then centrifuge Separate the extract and insoluble matter, and collect the upper extract; repeat the extraction step twice. The acetone insoluble matter of the soybean lecithin oil is more than 55%, and the PC value of phosphatidylcholine is 18%. Adding 1% by weight glass beads with a diameter of 0.8 mm in advance as a dispersant to the phospholipid raw material can improve the viscosity characteristics of soybean lecithin oil during stirring, expand the solvent contact area, and improve the lecithin extraction effect. In order to achieve the purpose of fully stirring and extracting, ultrasonic assisted ext...

Abstract

The invention relates to a preparation method of composite micro-encapsulated soybean lecithin powder for livestock breeding. The preparation method particularly comprises the following steps:(1) sufficiently stirring and extracting soybean phospholipid oil with ethanol, performing centrifugation on the extracted liquid and insoluble matters, collecting upper-layer extracted liquid, and repeating the extraction step twice; (2) merging the extracted liquid obtained by performing extraction twice, performing distillation under reduced pressure, recovering an ethanol solvent, and leaving soybean lecithin oily liquid; (3) heating water, adding sodium tripolyphosphate, whey powder and modified starch, and uniformly stirring the heated water, the sodium tripolyphosphate, the whey powder and the modified starch so that the sodium tripolyphosphate, the whey powder and the modified starch are dissolved; and (4) adding the soybean lecithin oil, uniformly emulsifying the soybean phospholipid oil, filtering out solids, and drying remaining liquid with a spray drying machine so as to obtain the micro-encapsulated soybean lecithin powder. According to the preparation method disclosed by the invention, the preparation technology is simple, the properties are stable, the lecithin powder is easy to store, the quality guarantee period is long, the prepared lecithin powder has notable effects in the respects of nutritional requirements of poultry and livestock and the health of livers, the bioactivity of the poultry and the livestock can be obviously improved, and the breeding benefits are improved.

Description

technical field [0001] The invention relates to the technical field of soybean lecithin extraction, in particular to technologies such as microcapsule encapsulation of soybean lecithin, compounding of nutrients and the like. Background technique [0002] Soybean lecithin is a product extracted from the oil foot of soybean oil, and its content in soybean is 1.2%-3.2% by mass. It is mainly composed of lecithin, cephalin, inositol phospholipids, phosphatidylserine, and phosphatidic acid. Soy lecithin has high nutritional value and physiological activity, and is also an excellent natural emulsifier. But from two aspects of nutritional function and physiological activity, lecithin is the most valuable component in soybean lecithin. [0003] From the perspective of nutrition, lecithin can promote the combination of cholesterol and protein molecules into a complex and exist in the blood, which can reduce the lipid infiltration of the blood vessel wall and inhibit the occurrence o...
