Description
Technical field
The invention belongs to food seasoning field, in particular to a kind of nutritive salt containing vitamin A strengthening and preparation method thereof.
Background technique
In recent years, people are to the dependence of electronic product so that excess eye-using is seen for a long time as the universal social concern in the whole world
Electronic curtain can consume a large amount of vitamin A.The eye diseases such as myopia, xerophthalmia, conjunctivitis, glaucoma more it is common simultaneously
Presentation becomes younger trend.In the case where social overall situation is immutable, reasonable supplement vitamin A is to preventing yctalopia and eyesight
Decline is highly important.
Vitamin A is also known as retinol, is a kind of fat-soluble alcohols material, is the important battalion for constituting retinal photoreceptor substance
Element is supported, cannot be synthesized by body, it is necessary to be taken in from the external world.But the factors such as light, heat, moisture, oxygen affect the stabilization of vitamin A
Property.Excessive vitamin A can accumulate in the liver and fat deposit of human body simultaneously, and excess intake will lead to poisoning.
China's dietary nutrition of urban residents guide recommend, adult male per capita daily vitamin A recommended intake be 800 μ g,
Adult female per capita daily vitamin A recommended intake be 700 μ g, the daily vitamin A recommended intake of pregnant woman be 700~
900μg.It is shown according to Chinese residents Nutritive status inquisition, city dweller's vitamin A intake wretched insufficiency, there are about 71% in crowd
People there are the risks of insufficiency of intake.
Summary of the invention
Problem unstable in view of above-mentioned vitamin A in the prior art and that intake is insufficient, the present invention provide one kind and are rich in
The Cardia Salt and preparation method thereof of vitamin A micro-capsule.
Technical scheme is as follows:
A kind of nutritive salt containing type vitamin A microcapsules, including type vitamin A microcapsules and edible salt A, the micro- glue of vitamin A
Capsule is using oleovitamin A as core material, using the mixture of gelatin, carboxymethyl cellulose and edible salt B as wall material, with emulsifier and admittedly
Agent is prepared for auxiliary material, wherein in the wall material mass ratio of gelatin, carboxymethyl cellulose and edible salt B be 4.5~

Embodiment 4
The measured performance parameter result of the nutritive salt containing type vitamin A microcapsules of above-mentioned preparation is as follows:
(1) electromicroscopic photograph
The mode of appearance for the microballoon containing type vitamin A microcapsules that observation is prepared under an optical microscope, as seen from the figure
Microcapsules are all rounded, do not rupture.
(2) Detection of Stability: type vitamin A microcapsules nutritive salt will be contained and stored 9 weeks under air drying environment, by micro- glue
The product surface of encapsulated is white, and in dry graininess, the oleovitamin A of package does not occur exosmose, storage-stable
It is good.The measurement result of embedding rate shows (such as Fig. 2) that the embedding rate of type vitamin A microcapsules is 75.38% after storage 9 weeks, relative to
Initial 81.12%, only reduces 5.74%.
(3) acid value measuring:
The acid value of the nutritive salt containing type vitamin A microcapsules is measured according to the following method: 1g sample being put into conical flask, body is added
Product is 0.01gmL than the drop left and right concentration of the benzene-alcohol mixed solution 50mL for being 1:1 and 10-1Ethanolic phenolphthalein solution is used
0.10mol/L potassium hydroxide solution titration, until indicator is become colorless by red as titration end-point, calculating acid value.
Sky is done with the sample of equivalent vitamin A and vitamin A-Ve (1%) (referring to the vitamin A containing 1% vitamin E)
It is white, METHOD FOR CONTINUOUS DETERMINATION 9 days, the acid value of daily stipulated time measurement each sample, as a result such as Fig. 3.Shown in Fig. 3, with the extension of time,
The acid value of vitamin A illustrates much higher than nutritive salt containing type vitamin A microcapsules, the acid value of vitamin A-Ve containing type vitamin A microcapsules
Nutritive salt, Ve can play effective inhibiting effect to the generation of grease free fatty acid, and rejection ability is substantially suitable.
(4) malonaldehyde (TBA) measurement of the nutritive salt containing type vitamin A microcapsules
The TBA (thiobarbituricacidα-) for testing microcapsules Va salt weighs 1g sample and 25.00mL trichloroacetic acid, filtering is added.
It takes 10mL filtrate in 25mL colorimetric cylinder, 10mL 0.02molL is added-1Thiobarbituricacidα- solution mixes, in 90 DEG C of water-baths
Inside holding 40min, after cooling, 4000rpm is centrifuged 5min, and supernatant is moved into nessler colorimetric tube, 5mL chloroform is added, shakes
Even, Aspirate supernatant measures its absorbance in 532nm, and the product of not being loaded not are blank.With equivalent vitamin A and vitamin A-Ve
(1%) sample does blank, and METHOD FOR CONTINUOUS DETERMINATION 11 days, as a result such as Fig. 4.Shown in Fig. 4, with the extension of time, vitamin A-Ve, dimension
The TBA of raw element A obviously increases, but the TBA of the nutritive salt containing type vitamin A microcapsules growth is not particularly significant.It can thus be appreciated that Ve
The vitamin A that content is 1% is weaker than type vitamin A microcapsules salt to the ability for inhibiting grease aldehyde material to generate.
The measured performance parameter of the above-mentioned nutritive salt containing type vitamin A microcapsules is with the nutritive salt that embodiment 1 is prepared
What example was measured.The performance parameter for the nutritive salt containing type vitamin A microcapsules that other embodiments are prepared is also suitable or close
In the measurement result of the nutritive salt of embodiment 1.
Embodiment 5
The type vitamin A microcapsules (sample 1) and wall material that salt is not added in wall material are prepared according to the method for embodiment 1
The type vitamin A microcapsules (sample 2) of middle addition salt.
20g sample 1 is weighed respectively and sample 2 is put into 150mL conical flask, and 10mL dehydrated alcohol is added.Conical flask is put
Into ultrasonic oscillator, under conditions of 10,000,000 HZ ultrasonic wave, concussion 30 minutes and solution 5mL after sixty minutes is taken respectively,
10mL potassium hydroxide and 30mL ethyl alcohol, heating saponification is added.According to colorimetric method for determining vitamin A in GB/T 5009.82-2003
Content.When being not added with that vitamin A content is calculated as 100% in the microcapsules sample of salt to handle the wall material after 60min, calculate
The relative amount of vitamin A in other samples.As a result such as Fig. 5, it is seen then that relative to the wall material for being not added with salt, in 30min
When, the leakage rate for adding the vitamin A of the wall material of salt reduces by 5.8%, and in 60min, the leakage rate of vitamin A is reduced
14.5%.Because adding the wall material mechanical performance enhancing of salt, microcapsules rupture amount is reduced, and content leakage is lacked.
