The technical scheme is that grease, protein, emulsifier and carbohydrate are used as raw materials; dissolving protein and emulsifier, adding oil, shearing, homogenizing, adding dissolved carbohydrate liquid, stirring, and spray drying to obtain microcapsule powder with surface oil content not higher than 5%. The invention has high oil loading rate, stable emulsion and simple process, and is suitable for industrial production. The microcapsule powder can be used as food alone or added into concocted milk powder, solid beverage, meal replacement milk shake and functional food.
Description
Technical Field
The invention belongs to the technical field of oil microencapsulation, and particularly relates to high oil-loading microcapsule powder and a preparation method thereof.
Background
The grease is not beneficial to storage, transportation and use due to the unique physical and chemical properties, and particularly, the grease has functional physiological activity. By microencapsulation technology, liquid or semisolid grease is converted into powder, so that on one hand, the grease can be well protected from damage of light, oxygen and the like, and on the other hand, the grease can be greatly conveniently applied to powder products.
The oil loading of the traditional microcapsule embedding technology is basically 10-50 percent (weight percentage). With the market development and the improvement of customer requirements, the traditional microcapsule embedding technology with low oil loading capacity cannot meet the market requirements, and is particularly characterized by emulsion layering and high surface oil (greater than or equal to 5%). For example, medium chain triglycerides, conjugated linoleic acid, OPO oil and walnut oil, etc., all require a microcapsule embedding technology with an oil loading rate of more than 50% to meet the market development demand.
The problems of the existing microcapsule embedding technology with high oil loading capacity include that when the emulsion made by the wall material system is subjected to heat preservation spray drying at the temperature of more than 45 ℃, the emulsion can be demulsified after one hour, which brings great pressure to continuous production, for example, a conjugated linoleic acid glyceride microcapsule powder with the application number of 201810772425.2 and a preparation method thereof, and a high-content medium chain triglyceride powdered oil with the application number of 201410216771.4 and a preparation method thereof, the modified starch is used as a wall material, and the micromolecule carbohydrate is used as a filling agent for embedding treatment; in addition, the product prepared by the wall material system has poor oxidation stability. The application number is 201410598018.6 a preparation method of a high oil-loading nutrient lipid microcapsule powder which can tolerate mechanical stirring, protein wall materials are dissolved, PH regulator is added, the reaction is carried out for 0.5 to 4 hours at the temperature of 40 to 70 ℃, the time of wall material pretreatment is too long, which is not beneficial to actual production, and in addition, the protein is easy to brown under the high temperature condition, which causes the product color to be darker. Application No. 201310536076.1A DHA algae oil microcapsule powder with high oil-carrying capacity and its preparation method, wherein the oil-carrying capacity is 33-50%, and the oil-carrying capacity is at a low level.
Disclosure of Invention
In order to overcome the technical defects, the invention provides high oil-loading microcapsule powder and a preparation method thereof.
The technical scheme of the invention is as follows: the high oil-loading microcapsule powder comprises the following raw materials in percentage by mass:
45-80% of grease, 4-10% of protein, 0.5-2% of emulsifier and 8-50.5% of carbohydrate.
More preferably, the oil and fat is one or a mixture of several of medium chain triglyceride (MCT oil and fat), conjugated linoleic acid, 1, 3-dioleic acid-2-palmitic acid glyceride (OPO oil and fat), walnut oil, olive oil, sea buckthorn oil, peony seed oil and the like.
In a further preferable mode, the protein is one or a mixture of more of sodium caseinate, casein, whey protein, soy protein isolate and the like.
In a further preferable mode, the emulsifier is one or a mixture of more of mono-diglycerol fatty acid ester, sodium stearyl lactate and sucrose fatty acid ester.
In a further preferable mode, the carbohydrate is one or a mixture of more of glucose syrup, maltodextrin, polydextrose, resistant dextrin, solid corn syrup, fructo-oligosaccharide, lacto-oligosaccharide, isomaltooligosaccharide and the like.
The preparation method of the high oil-loading microcapsule powder comprises the following steps:
(1) dissolving the protein and the emulsifier in water of 40-80 ℃, and preserving the temperature for 20-50 minutes for later use;
(2) dissolving the carbohydrate in water to obtain liquid with solid content of 65-75%, heating to 40-80 deg.C, and holding for 20-50 min;
(3) heating the grease to 40-80 ℃, and preserving the heat for 10-30 minutes for later use;
(4) slowly adding the grease in the step (3) into the aqueous solution in the step (1) under the condition of stirring, uniformly stirring, shearing for 5-20 minutes at 4000-10000 r/min, and homogenizing for 2-4 times;
(5) adding the carbohydrate liquid obtained in the step (2) into the step (4), uniformly stirring, and then controlling the temperature of the materials at 40-50 ℃ for spray drying to obtain microcapsule powder.
Compared with the prior art, the invention has the following advantages:
1. the oil loading rate is high, and compared with the traditional microcapsule technology, the maximum oil loading of the microcapsule disclosed by the invention can reach 80%.
2. Compared with modified starch wall materials, the emulsion made by the protein wall material is more stable, which lays a good foundation for later spray drying and quality stability.
3. Simple process and is suitable for industrial production.
4. In the research process, the invention discovers that according to the prior high oil-loading microcapsule technology: mixing protein or modified starch wall material, emulsifier and carbohydrate filler, dissolving to form emulsified phase, adding oil, shearing, homogenizing, spray drying to obtain microcapsule powder with surface oil of more than 5%. The surface oil of the invention can be less than or equal to 5 percent, and the microcapsule powder obtained by the method has better solubility.
