In addition, the present invention also provides the preparation method of above-mentioned high-load medium chain triglyceride powdered oil, it is characterized in that: take converted starch and/or glucose syrup as main wall material, adopt high-pressure homogeneous emulsification and spray drying technology, using medium chain triglyceride as core, carry out microencapsulation embedding, obtain medium chain triglyceride powdered oil.
Preferably, take medium chain triglyceride, starch sodium octenyl succinate or/and glucose syrup etc. are primary raw material, be equipped with other raw materials such as water-soluble dietary fiber,, package processing operation dry, cooling through fusing, mixing, emulsifying, spraying made high-load medium chain triglyceride powdered oil product.
In addition, the present invention also provides the preparation method's of above-mentioned high-load medium chain triglyceride powdered oil concrete technology step,,
Step 1, oil-soluble material is added and in medium chain triglyceride, adds thermal agitation fusing and form oil phase, Water-solubility Material is added and in purified water, adds thermal agitation and dissolve formation water.
Wherein, fusion temperature should be controlled at 40 ℃~90 ℃.
Step 2, oil phase is slowly added in aqueous phase system to even 10 minutes~60 minutes of shear-mixed.
The step of above-mentioned fusing and mixing, specifically,, the molten class material of oil (as: emulsifying agent etc.) is added and in medium chain triglyceride, adds thermal agitation fusing, water-soluble wall material adds and in purified water, adds thermal agitation and dissolve, and then oil phase is slowly added in aqueous phase system shear-mixed even.
Step 3, test solid content add purified water as required, and regulate pH to 6.0~8.0, stir 40 ℃~90 ℃ of insulations; Under one-level emulsifying pressure 100bar~600bar, double-stage homogenization Emulsification pressure 10bar~50bar condition, carry out high shear emulsifying;
Step 4, employing centrifugal spray dryer equipment or pressure spray dryer equipment are sprayed dry, and its 80 ℃~210 ℃ of EAT control, leaving air temp are controlled 50 ℃~110 ℃;
Step 5, product are cooled to after normal temperature, pack.
Above-mentioned steps five, specifically,, product of the present invention is cooled to normal temperature state adopts automated packaging equipment to be processed into different packing specifications, it is worthy of note, because its intended application field is field of food, therefore it is produced preferably and carries out under more than 300,000 grades clean environments requires.
In addition, in above-mentioned preparation process, also possess such optimal technical scheme, the mixture of one or more, in converted starch, glucose syrup, water-soluble dietary fiber, albumen powder and the weight ratio of the emulsion after homogeneous are 1:10-3:5.
The high-load medium chain triglyceride powdered oil of preparing according to above-mentioned formula and method, wherein, this component of medium chain triglyceride accounts for 50~80% in final products, and this product has the advantages that oil-containing ratio is high.
The microcapsules of the high-load medium chain triglyceride powdered oil of preparing according to said method, these microcapsules are generally simple type, still, can, according to the needs of production and application, be made into the configurations such as multi-core type, many walls type.
It is worthy of note, the medium chain triglyceride powdered oil of the high-load of composition and engineering manufacture of the present invention can be used as a kind of food component or food additives.Can be widely used in the health foods such as the food such as formula milk, milk tea, solid beverage, candy, liquid beverage and tablet, hard shell capsules, electuary.
effect of the present invention:
In the present invention, selected wall material, as: converted starch, syrup, water-soluble dietary fiber, albumen powder can be used alone or as a mixture and carry out embedding.
The defects such as the microcapsules that adopt wall material provided by the invention to manufacture, can overcome conventional wall material embedding rate low, and the high and properties of product of surperficial oil content are unstable, can reach very high medium chain triglyceride fat content.
In the present invention, take converted starch (as: starch sodium octenyl succinate), glucose syrup, water-soluble dietary fiber, albumen powder etc. is main wall material, adopt the technology such as high-pressure homogeneous emulsification and spraying are dried to process and formula Design, medium chain triglyceride microencapsulation parcel is prepared into the powdered oil that is rich in dietary fiber.
In the process of research and development, by to the optimization of concrete technology parameter and adjustment, the present invention finds, in the situation that adopting raw material provided by the invention, when adopting " oil-soluble material is added and in medium chain triglyceride, adds thermal agitation fusing and form oil phase, Water-solubility Material is added and in purified water, adds thermal agitation and dissolve formation water; Oil phase is slowly added in aqueous phase system to even 10 minutes~60 minutes of shear-mixed; Test solid content adds purified water as required, and regulates pH to 6.0~8.0, stirs 40 ℃~90 ℃ of insulations; Under one-level emulsifying pressure 100bar~600bar, double-stage homogenization Emulsification pressure 10bar~50bar condition, carry out high shear emulsifying; Adopt centrifugal spray dryer equipment or pressure spray dryer equipment to spray dry, its 80 ℃~210 ℃ of EAT control, leaving air temp are controlled 50 ℃~110 ℃." when this specific processing step and condition, can access a kind of, stability better product higher compared to conventional formulation and technique embedding rate.
For example: in the present invention, point out, fusion temperature should be controlled between 40 ℃~90 ℃, experiment is found, feedstock property according to the present invention and the needs that become micro-capsule.When temperature is during lower than 40 ℃, raw material cannot melt completely, and then makes the Product mix can not be even; When temperature is during higher than 90 ℃, the nutritional labeling of raw material will be fully or is partly destroyed, and then causes product to lose the value that it is applied to field of food, even may generation property become, and then it is no longer stable to cause that encystation rate is low, product becomes.
The present invention also points out, the uniform time of shear-mixed is 10 minutes~60 minutes, experiment is found, is worked as incorporation time, while being less than 10 minutes, mix and also do not reach even, affect the formation of stable prod, when incorporation time is greater than 60 minutes, on end properties without too much impact, from the angle of production efficiency, consider, should select 60 minutes with interior scheme.
In addition, also having limited the adjustable range of pH in technique and stirred the conditions such as temperature range of insulation, is to consider not being destroyed of the performances such as the application of product and nutrition, on the other hand on the one hand, according to formula of the present invention, the encystation best results under this condition.
It is worthy of note, product of the present invention can be widely used in food, as: in the health foods such as the food such as formula milk, milk tea, solid beverage, candy, liquid beverage and tablet, hard shell capsules, electuary.The product obtaining according to formula of the present invention and manufacture method, after being applied to above-mentioned field for improving its nutritive value, improve institutional framework, exterior quality and the palatability of food, in the shelf life of raising product, significant to improving the security of powdered oil product.
