Description
Technical field
The present invention relates to the preservation technology field of food, medicine, relate in particular to a kind of pulvis oxygen indicator that detects oxygen content in food or medicine packing and preparation method thereof.
Background technology
In the time preserving food, medicine, airborne oxygen can make food, medicine oxidation, thereby the quality of food, medicine is reduced, and therefore, in order to prevent that food and medicine quality when the preservation from reducing, conventionally it is packed with together with deoxidizer etc.; Although be all fitted with deoxidizer, deoxidizing antistaling agent etc. in a lot of food and medicine packing on the market now, whether deoxidizer wherein can play anti-oxidation effect effectively, is not fully aware of for common consumer.
For this reason, in recent years, have to adopt together with oxygen indicator (detection agent) and deoxidizer etc. and enclose in packing container, by oxygen indicator to the method that has no oxygen to detect in packing.Oxygen indicator be a kind of can be according to the variation of tone the material that carries out visuognosis that has or not to oxygen in packing container.Whether the tone that ordinary consumer can present according to oxygen indicator, directly tell in packing and have oxygen to exist, and whether food or medicine have obtained preservation under anaerobic state.
Current oxygen indicator is mostly wire or the scraps of paper, it is not easy to realize batch production, and produce dyeing complexity, have relatively high expectations, equipment cost is high, the indicated effect of sheet or Linear oxygen tracer agent is very not sensitive in addition, accurately, when the oxidized or partial oxidation of product in packing, the interior oxygen concentration of packing is more than 0.5～1% or when even higher, color when this oxygen indicator still remains anaerobic state, and whether consumer differentiates the interior aerobic of packing (as packaging bag internal indicator shows red by the indicating effect of oxygen indicator, think anaerobic, but be actually aerobic), this will misguide the consumer, give wrong information of people, thereby do not reach the quality assurance of consumption safety food and medicine.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the object of the present invention is to provide one to have that redox property developing sensitivity is high, indication information is accurate, and production technology simple, easily realize pulvis oxygen indicator of batch production and preparation method thereof.
To achieve these goals, technical scheme of the present invention is as follows:

Preferably, described pulvis carrier is one or more in high-molecular organic material, neutral alumina particle, talcum powder, light magnesium carbonate, saponite powder, artificial zeolite, consider itself and the mixing of other materials, preferably high-molecular organic material, such as ion exchange resin, cellulosic material; Generally preferred neutral alumina particle and light magnesium carbonate.
Preferably, described pH alkaline conditioner is one or both in NaOH, potassium hydroxide or sodium carbonate.
Preferably, described oxygen indicator solvent is one or both mixing in water or ethanol.
More preferably, calculate by weight, comprise pulvis carrier 70～96.88, pH alkaline conditioner 0.001～0.5, developer 0.01～0.5, reducing substances 1～10, surfactant 0.1～5 and pulvis oxygen indicator solvent 2～14; Wherein the orchil in developer accounts for 0.001～0.5 of pulvis oxygen indicator by weight percentage, and oxidation-reduction quality pigment accounts for 0.001～0.5 of pulvis oxygen indicator by weight percentage.
Pulvis oxygen indicator as above, its preparation method is as follows:
First reducing substances, surfactant are become to reducing solution with the oxygen indicator solvent of part;
Then orchil, methylene blue are become to nitrite ion with remaining oxygen indicator solvent;
Finally reducing solution, nitrite ion, PH alkaline conditioner are mixed, then the oxygen indicator solvent of drying remove portion to oxygen-free seal and get final product with pulvis carrier.
This kind of preparation method is simple, easily realizes batch production, and there will not be the problem of sheet or wire dyeing difficulty, uses device simple, low for equipment requirements, easily realizes and producing in enormous quantities.
Pulvis oxygen indicator of the present invention, anaerobic developing sensitivity is high, indication information is accurate, as oxygen indicator O around
2when concentration>=0.3%, oxygen indicator is blueness or bluish violet, and oxygen indicator is O around
2when concentration≤0.3%, oxygen indicator takes on a red color, and guarantees that by colour developing in bag food packaging safety is reliable, improves the fresh-keeping effect of food; One aspect of the present invention can promptly and accurately distinguish in packaging bag, whether oxygen exists the seal standard that whether reaches product to the sealing state that exceedes safety standard and packing simultaneously, prevent that defective food from coming into the market, for people's healthy living has been erected safety wall one; The colour developing variation of this pulvis oxygen indicator in the time having oxygen and no oxygen is reversible on the other hand, therefore can reuse.
