Embodiment 7
SO2Residual quantity test
SO2Residues detection method includes: chromatography, titration, Kjeldahl's method, MW method, colorimetric method and fluorescence method, excellent
It is selected as titration.The specific method is as follows:
10g is accurately weighed respectively through passing through in treated the fresh Rhizoma Gastrodiae of the Rhizoma Gastrodiae antistaling agent in embodiment 1-4 and comparative example
Fresh Rhizoma Gastrodiae after Preservation Treatment, is respectively placed in two neck round-bottom flasks, adds water 300mL, uses 1mL starch indicator solution as absorption
The hydrochloric acid solution of the 6mol/L of 10mL is added in liquid in separatory funnel.Condenser pipe is opened, the upper end of condenser pipe connects rubber air guide
Pipe, gas-guide tube connect nitrogen inlet.Open nitrogen, flow velocity 0.2L/min.Open separatory funnel stopcock, make hydrochloric acid solution 10mL into
Enter in flask.The solution in two neck flasks is heated to boiling, is carried out after keeping slightly boiled about 3min with the iodine titration solution of 0.01mol/L
Absorbing liquid is titrated, until absorbing liquid color becomes blue or the incomplete fading of bluish violet 30s, and by titration results blank test school
Just.The iodine titration solution (0.01mol/L) of every 1mL is equivalent to the SO of 0.6406mg2。
Calculation formula is sulfur dioxide residual quantity (mg/g)=((A-B) × C × 0.032 × 1000)/W in test sample
A: test sample consumes the volume of iodine titration solution, mL；
B: blank consumes the volume of iodine titration solution, mL；
C: iodine titration solution concentration, 0.01mol/L；
W: the weight of test sample, g；
0.032 is the weight of the comparable sulfur dioxide of every 1mL iodine titration solution (1mol/L), g.
The fresh fresh-keeping experiment of Rhizoma Gastrodiae is carried out using the antistaling agent of 1-4 of the embodiment of the present invention, fresh Rhizoma Gastrodiae picks up from Jinzhai County, Anhui Province.
Preservation method are as follows: fresh Rhizoma Gastrodiae is cleaned up, is put into steamer and steams the heart, natural cooling after taking-up, then
Rhizoma Gastrodiae is respectively implanted in the container of the antistaling agent equipped with embodiment 1-4 and is stored, covered, overnight, taking-up Rhizoma Gastrodiae is placed in common thin
Film bag, sealing.The fresh gastrodia elata of 2.5kg is stored in each container.
Sulfur dioxide residue detection is carried out according to above-mentioned sulfur dioxide titration detection method, result is referring to shown in table 3.
Comparative example
Comparative test uses market product processing method, and the source of fresh Rhizoma Gastrodiae is identical, and preservation method is as follows:
Cook: fresh Rhizoma Gastrodiae being placed in boiling water and cooks 20 minutes to the saturating heart, pulled out with fishing set cool at room temperature it is spare.
It impregnates: taking sodium pyrosulfite 3.5g, point 5 additions are equipped in the stainless steel barrel of 10L distilled water, by cooked day
Fiber crops are put into container, soaked overnight.
Packaging: taking out Rhizoma Gastrodiae from soak, drain extra antistaling agent, be placed in general thin bag, seals.Each container
Each storage 2.5kg fresh gastrodia elata.Sulfur dioxide residue detection, result are carried out according to above-mentioned sulfur dioxide titration detection method
For " comparative example " in table 3.
3 SO of table2Residual quantity experimental result (mg/kg)
| 0 month | 12 months | 18 months | 24 months | |
| Embodiment 1 | 15 | 10 | 5 | 0 |
| Embodiment 2 | 3 | 0 | 0 | 0 |
| Embodiment 3 | 6 | 5 | 0 | 0 |
| Embodiment 4 | 6 | 2 | 0 | 0 |
| Comparative example | 2560 | 1800 | 1300 | 960 |
By the data in table 3 it can be concluded that, antistaling agent made from embodiment 1-4 processing fresh Rhizoma Gastrodiae, the SO of fresh Rhizoma Gastrodiae2
Residual quantity is minimum in 2 residual quantity of embodiment, higher in embodiment 1, embodiment 1-4 treated fresh Rhizoma Gastrodiae SO2Residual quantity is equal
Meet the use standard of food additives.And SO in comparative example2Residual quantity severely exceeds, and does not meet national standard.Embodiment with
Comparative example compares significant difference, and the usage amount of sodium pyrosulfite meets food additives using standard in antistaling agent, can eat safely
With or it is medicinal, for finished product without tart flavour, residual quantity is low.
Embodiment 8
Pass through SO in sulfate by ion chromatography embodiment 1-42Residual quantity.Two in Rhizoma Gastrodiae are extracted using buffered formaldehyde liquid
Sulfur oxide is sulfate radical through hydrogen peroxide solution oxidative absorption, the content of sulfate radical is measured by ion chromatographic column, passes through external standard method
It is quantitative, finally it is converted into the residual quantity of sulfur dioxide.
Embodiment 9
SO in embodiment 1-4 is detected by Kjeldahl's method2Residual quantity.In the distillation cascade of closed kjeldahl apparatus
Hydrochloric acid is added to be acidified Rhizoma Gastrodiae sample, opens distillation switch, carries out heating distillation cascade, it is made to release sulfur dioxide.When
Sulfur dioxide gas, which is absorbed after apparatus for supercooling by acetic acid lead solution, generates lead sulfate.Then the concentrated sulfuric acid is added and is generated in liquid
Be acidified, with iodine standard solution be titrated to blue and in 30s it is colour-fast until.According to consumed iodine standard solution
Amount, calculates the residual quantity of sulfur dioxide in Rhizoma Gastrodiae sample.
The beneficial effects of the present invention are: Rhizoma Gastrodiae antistaling agent provided by the present invention has the cost of raw material cheap, through Rhizoma Gastrodiae
Antistaling agent treated Rhizoma Gastrodiae has SO2The low advantage of residual quantity meets edible or medicinal standard.
The present invention also provides a kind of Rhizoma Gastrodiae preservation methods, and the day ramie product after adding Rhizoma Gastrodiae antistaling agent has color white, matter
Firmly, the advantage of apparent freshness height and Gastrodin, gastrodia elata polysaccharide holding time length.
The foregoing is merely the preferred embodiment of the present invention, are not intended to restrict the invention, for this field
For technical staff, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any
Modification, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
