Edible microcapsule mineral matter nutritive salt and preparation method thereof
Technical field
The invention belongs to food processing field, be specifically related to microcapsules nutritive salt that contains on calcium, iron, zinc, selenium and preparation method thereof.
Background technology
At present, the processing of domestic and international common nutritive salt, report is arranged in the literature, but all be to adopt the simple physics hybrid mode, nutrition fortifier directly admixed in the salt that microcapsules technology is used widely in food industry, and after adopting microcapsules technology with calcium, iron, zinc, selenium nutrition-intensified dose of microencapsulation, microcapsules nutritive salt or microcapsules compound nutritional salt are produced in regeneration, and this type of nutritive salt does not appear in the newspapers at home as yet, also do not see the Related product listing.There is following problem in the existing nutritive salt in market:
1, nutritive salt on the market all is to adopt simple physics to mix, because the proportion of nutrient and salt is different, is difficult to mix in actual production, has caused micro-mixing inhomogeneous, directly causes the unbalanced phenomenon of people's intake.
2, because nutrition fortifier and salt color have bigger difference, owing to mix inequality, thus caused the irregular colour of nutritive salt, influenced the nutritive salt sense organ.
3, because iron enriched nutrient has bigger iron fishy taste, the simple mixing makes nutritive salt discharge heavier iron fishy taste, makes people be difficult to accept.
4, human body needs ferrous ion to improve HC, but common nutritive salt makes and increase chalybeate and place air very easily to be oxidized to ferric ion, thereby is difficult to be absorbed by people.
5, common nutritive salt all is that nutrition fortifier directly is added in the salt, can cause salt to the aggravation of water in air branch adsorption phenomena, thereby make micro-oxidation, and is rotten, even go mouldy, and nutritive salt caking etc. have shortened the nutritive salt shelf life.
Summary of the invention
The object of the present invention is to provide edible microcapsule nutritive salt of nutrition fortifiers such as containing calcium, iron, zinc, selenium and preparation method thereof.
The objective of the invention is to realize in the following manner.
Edible microcapsule mineral matter nutritive salt is to have mixed the nutrition fortifier microcapsules in edible salt, and described nutrition fortifier microcapsules are that the glue that will form behind wall material and the nutrition fortifier homogeneous is sprayed at the formation of sodium chloride surface.
Described nutrition fortifier is selected from a kind of in calcium lactate, zinc lactate, EDTA ferrisodium, the sodium selenite; Described nutritive salt contains one or more nutrition fortifier microcapsules.
Described wall material is edible Arabic gum, starch, sodium alginate and edible gelatin.
The preparation method of described edible microcapsule mineral matter nutritive salt, be that the glue that will form behind wall material and the nutrition fortifier homogeneous is through super-dry, powder essence, screening, make described nutritive salt with edible salt is mixed, form nutrition fortifier microcapsules drying again but the glue behind the homogeneous will be sprayed onto the sodium chloride surface.
Described homogenizing process has experienced twice, and the used wall material of homogeneous is edible Arabic gum and starch for the first time; The used wall material of homogeneous is sodium alginate and edible gelatin for the second time.
Described nutrition fortifier microcapsules are with behind the edible Arabic gum of 5-15g, 5-35g starch, 500-3000ml deionized water, the 20-40g nutrition fortifier homogeneous, continue the mixed solution of adding 500-3000ml sodium alginate and edible gelatin and carry out the homogeneous second time, containing sodium alginate and the mass percent that mass percent is 5-10% in the described mixed solution is the edible gelatin of 5-20%, glue 1000-6000ml behind the second time homogeneous is sprayed at 100-1000g sodium chloride surface, through super-dry, powder essence, the formation of screening back.
The concrete preparation method of described edible microcapsule mineral matter nutritive salt is as follows:
(1) it is mixed to eat Arabic gum 5-15g, starch 5-35g, deionized water 500-3000ml, and heat temperature raising is to 50-90 ℃, after fully stirring, add nutrition fortifier 20-40g, stir and put into homogenizer after 4-8 minute and carry out homogeneous, homogenization pressure is 10-50MPa, and the time is 15-50 minute; In the material behind the first time homogeneous, continue to add the mixed solution that 500-3000ml contains sodium alginate and edible gelatin and carry out the homogeneous second time, containing sodium alginate and the mass percent that mass percent is 5-10% in the described mixed solution is the edible gelatin of 5-20%, homogenization pressure is 10-50MPa for the second time, and the time is 10-40 minute;
(2) in the mixer of band heating, add sodium chloride 100-1000g, stir on the limit, the limit heating is warming up to 50-90 ℃, and the glue 1000-6000ml employing press atomization device that homogeneous is good for the second time then is sprayed at the sodium chloride surface equably, spray on the limit, stir on the limit, and mixing time is 15-30 minute, and insulation was 5-30 minute after spray finished, temperature is 40-90 ℃, makes its drying;
(3) dried material is pulverized, after 80 purpose vibratory sieves, 80 order screenings are the microcapsules nutrition fortifier;
(4) with microcapsules nutrition fortifier and edible salt, put into mixer, stirred 5-20 minute, be edible microcapsule mineral matter nutritive salt.
Make calcium lactate, zinc lactate, EDTA ferrisodium, sodium selenite hardening agent microcapsules as stated above respectively.
Take by weighing calcium lactate microcapsules 10-60g respectively, EDTA ferrisodium microcapsules 5-20g, zinc lactate microcapsules 0.5-5g, sodium selenite microcapsules 1-50mg, edible salt 1000-3000g puts into mixer, stirs 5-20 minutes.Weighing then, pack qualified after testing after, be edible microcapsule calcium, iron, zinc, selenium compound nutritional salt.
Advantage of the present invention:
1, adopt microcapsules technology to produce edible microcapsule mineral matter nutritive salt, nutrition fortifier is covered by multilayer resist, and some acid ingredients, chemically-reactive substance have all been avoided directly contacting with air and other component and the various physical-chemical reactions that cause.Solved micro-oxidation in the salt, rotten, even go mouldy, the nutritive salt caking has shortened defectives such as nutritive salt shelf life.
2, add edible sodium chloride in encapsulation process and carry out counterweight, solved because the proportion of nutrient and salt is different, be difficult to mix in actual production, the trace element that causes mixes inhomogeneous, and then causes the unbalanced phenomenon of people's intake.
3, owing to designed dissolving and releasing mechanism in advance, can be between the most in good time in the suitableeest speed release nutrient.
4, edible microcapsule mineral matter nutritive salt is compared with commercially available nutritive salt, have and mix, the pale yellow unanimity of color, characteristics such as iron taste is light, water-soluble not to develop the color, absorbability is strong, good stability, shelf life is long, security is good have greatly improved the nutritive value of nutritive salt.
