Description
Technical field
The invention belongs to new material technology fields, and in particular to a kind of taste removal agent material for fresh preservation.
Background technology
With the continuous improvement of quality of life, people are especially also higher and higher to the quality requirement of food to the consumer goods,
And freezing and refrigeration product can make the raw and fresh food in fresh cabinet generate various smells or peculiar smell due to putting for a long time, some
Smell eliminates the quality that may influence raw and fresh food not in time, causes fruit well-done too early, and raw and fresh food is rotten to rot even to pollute
The problems such as, and still lack the new material eliminated for the peculiar smell in fresh cabinet at present.
Invention content
Problem provides a kind of taste removal agent material can be used for the anti-peculiar smell of fresh cabinet to the present invention for the above-mentioned prior art.
A kind of taste removal agent material of the present invention, is prepared using following methods step：
(1) by inorganic mineral nitric acid dousing 1-2 hours, it is washed to neutrality, obtains solids A；It is 5% to prepare mass concentration
~8% aqueous slkali B；It is 1 in mass ratio by solids A and solution B：2 are mixed, and are dehydrated, dry, in nitrogen atmosphere in
800~1200 DEG C are calcined 10~40 minutes, and solid C is obtained；
(2) solution D that mass concentration is 10%~15% is prepared；The solution D is citric acid or polyvinyl alcohol and water shape
At mixed liquor；Solid C and solution D are pressed 1：1~5 mass ratio is mixed, and is filtered, dry, cooling, grinds solid
Body adsorbent E；
(3) PVA solution for preparing mass concentration 5%~6%, is added solid absorbent E, suspension is mixed to obtain；It will
Gained suspension is atomized, and the droplet drying of atomization is placed in glutaraldehyde steam and react 1~2 hour, dry 2~8h to get.
Preferably, step (1) the nitric acid mass concentration 30%~40%.
It is calcined 20~30 minutes in 800~900 DEG C in nitrogen atmosphere after preferred steps (1) are dry.
Step (2) described solution D is citric acid solution.
Step (2) solid C and solution D mass ratio 1：2.
Step (3) solid absorbent E accounts for the 1%~2% of PVA solution quality.
The present invention ensure that inorganic mine by carrying out organically-modified by inorganic mineral and being handled by effective calcination process
The stabilization porous structure of object at low ambient temperatures makes inorganic mineral be provided with stronger capture to gas molecule by organically-modified
Ability, the taste removal agent material can effectively adsorb a variety of organic gases and inorganic gas in low temperature environment, can be used for inhaling
It echos and eliminates generated peculiar smell in the agricultural product especially raw and fresh food preservations such as vegetable and fruit.
