The invention refers to the food industry, in particular to a process for reducing the patulin content in fruit juices with a microporous resin, to a device for realization of the process and to a process for used resin regeneration The process for reducing the patulin concentration in fruit juices includes passage of the juice through a sorbent and collection of the juice with a reduced concentration of patulin, wherein, according to the invention, as sorbent is used resin having an abundance of micropores with a minimal dimension under 20Å, and the surface of the micropores is capable of retaining the patulin due to chemosorption forces The device for realization of the process includes at least a reservoir with a sorbent layer, provided with a juice collecting and feeding system, wherein, according to the invention, the sorbent represents a microporous resin layer, and the reservoir is additionally equipped with a reagent collecting and feeding system for regeneration in situ of said resin. The process for resin regeneration includes treatment of the resin with ammonia or a volatile base, which transform the retained patulin into an easily washable derivativeThe result of the invention consists in the efficient reduction of patulin content in fruit juices by means of microporous resin with subsequent regeneration thereofClaims: 28Fig.: 13 |
