From above technical scheme, a kind of Cypres provided by the invention and preparation method thereof, the surface is applied
Jelly includes following components by weight percentage：Bulk composition 20%-40%, porous resin 5%-15%, mould inhibitor 1%-
15%th, sustained release agent 0.2%-4%, auxiliary agent 0.5%-2%, surplus are water.During preparation, bulk composition is added in reaction kettle, is added
Water stirs, and then adds auxiliary agent stirring, sustained release agent is mixed into mould inhibitor, then adds porous resin, is dissolved in water, is mixed
Solution is closed, then mixed solution is added drop-wise in reaction kettle, at this time, is filled with sustained release agent in the hole of porous resin, in sustained release agent
Mould inhibitor is wrapped up, reaches the effect slowly discharged.The Cypres of the present invention have good barrier, can not only obstruct oxygen
The factors such as gas and water, moreover it is possible to adverse effect of the bacterium to food is effectively obstructed, after tin foil sprays the Cypres of the present invention,
The suppression to food mould can be kept for a long time, realize the purpose for extending effective period of food quality.
The preparation method of each Cypres described in two~embodiment of the embodiment of the present application seven, can refer in embodiment one
Description and explanation, identical part can be cross-referenced between each embodiment.
Those skilled in the art will readily occur to the present invention its after considering specification and putting into practice invention disclosed herein
