Abstract
A process and device are disclosed for detoxicating and decontaminating produce, in particular cereals and other seeds used as foodstuffs and/or fodder. The produce or cereals are subjected to an ultrasonic treatment in an aqueous medium. It has been discovered that such a treatment surprisingly causes effective decontamination or detoxication of the contaminated produce, without affecting the appearance, taste, nutritive value of the decontaminated produce, above all cereal produce.
Claims53
Method for the decontamination and detoxification of a material contaminated with at least one mycotoxin, said material being selected from the group consisting of foodstuffs,feedstuffs, mycotoxin contaminated aqueous suspensions, and mycotoxin contaminated aqueous solutions, said at least one mycotoxin being a fusarium mycotoxin of the trichothecene series of the general formula ##STR5## with the radicals R.sub.i to R.sub.5 being trichothecene mycotoxins including T-2 toxin (T-2), HT-2 toxin (HT-2), diacetoxyscirpenol (DAS), monoacetoxyscirpenol, neosolaniol, nivalenol (NIV), deoxynivalenol (DON), 3-acetyldeoxynivalenol (3-AcDON), T-2 tetraol, scirpentriol, fusarenon, crotocin, and satratoxin H, the method comprising the step of subjecting the material in an aqueous liquid to ultrasonic energy of a frequency and for a period of tame sufficient to induce microcavitation in the aqueous liquid and sono-chemically induced reactions of said at least one mycotoxin.
Method for the decontamination or detoxification of a material contaminated with at least one mycotoxin, wherein said material is selected from the group consisting of foodstuffs, feedstuffs, aqueous solutions contaminated with said mycotoxin and aqueous suspensions contaminated with said mycotoxin, the method comprising the step of subjecting said mycotoxin contaminated material while in a liquid to ultrasonic energy of a frequency and for a period of time sufficient to induce microcavitation in the liquid medium and sono-chemically induced reactions of the mycotoxins.
Method for the decontamination or detoxification of an aqueous liquid contaminated with at least one mycotoxin, the method comprising the step of treating said aqueous liquid with ultrasonic energy of a frequency and for a time period sufficient to induce microcavitation in the liquid and sono-chemically induced reactions of said at least one mycotoxin.
Apparatus for the decontamination and detoxification of a material contaminated with at least one mycotoxin, said material being selected from the group consisting of foodstuffs, feedstuffs, aqueous solutions contaminated with the mycotoxin and aqueous suspensions contaminated with the mycotoxin, the apparatus comprising at least one treatment container (28) for receiving said material and a treatment liquid, ultrasonic generators (30) arranged on said treatment container (28), said treatment container being formed as a vertically arranged treatment channel (28) having side surfaces facing the channel through which said material flows and said ultrasonic generators (30) being arranged distributed over a length of the treatment channel (28) on the side surfaces (32) of the treatment channel (28).
Apparatus for the decontamination and detoxification of a material contaminated with at least one mycotoxin, said material being selected from the group consisting of foodstuffs, feedstuffs, aqueous solutions contaminated with the mycotoxin and aqueous suspensions contaminated with the mycotoxin, the apparatus comprising at least one treatment container for receiving said material and a treatment liquid, ultrasonic generators arranged on said treatment container, said treatment container being formed as a treatment channel having a cross-section in the form of an equilateral polygon and side surfaces facing the channel through which said material flows, said ultrasonic generators being arranged distributed over a length of the treatment channel on the side surfaces of the treatment channel.
Apparatus for the decontamination and detoxification of a material contaminated with at least one mycotoxin, said material being selected from the group consisting of foodstuffs, feedstuffs, .aqueous solutions contaminated with the mycotoxin and aqueous suspensions contaminated with the mycotoxin, the apparatus comprising at least one treatment container for receiving said material and a treatment liquid, ultrasonic generators arranged on said treatment container, said treatment container being formed as a treatment channel having a length of 0.4 m to 12.0 m and side surfaces facing the channel through which said material flows, said ultrasonic generators being arranged distributed over a length of the treatment channel on the side surfaces of the treatment channel.
Apparatus for the decontamination and detoxification of a material contaminated with at least one mycotoxin, said material being selected from the group consisting of foodstuffs, feedstuffs, aqueous solutions contaminated with the mycotoxin and aqueous suspensions contaminated with the mycotoxin, the apparatus comprising at least one treatment container (28) for receiving said material and a treatment liquid, ultrasonic generators arranged on said treatment container, said treatment container being formed as a plurality of treatment channels arranged in series, each treatment channel having an inlet, an outlet and a side surface, a conveyor duct connecting the outlet of each treatment channel to, an inlet of a following treatment channel, an outlet of a last treatment channel being connected to one of a collection container and a device for further processing said material, the side surfaces facing the channels through which said material flows, at least one of said ultrasonic generators being arranged on the side surfaces of each treatment channel.
