Dear All

 

Wishing You A Happy & Prousperous Year 2014.

 

We are manufacturer's of fruit pulp & concentrate (Mango, Guava, Papaya). One of our important opearation is fruit washing, where till today we are using Sodium Hypochloride as the biocide for reducing the bio-burden of the fruits. We have initiated a process to change over to chlorine dioxide instead of Sodium Hypochloride. Can anybody advice whether it will be wise or not. We will be thankful if anybody can provide us with the risk/ hazard that we should focus while considering chlorine dioxide for such operation.

 

Thanking You All

Hello Sujit,

   Several case reports of accidental inhalation exposure to chlorine dioxide have been reported and it is occupational hazard.You have to keep Material safety Data Sheet handy if you are going for it.The plant has to be installed at secure location and person operating the plant should be well trained and well versed in disaster Management.

Hi,

I am working on implementing ISO22000 in the hospital Kitchen.Right now raw fruits and veggies are being washed using portable water.Can some body advice the best method used for washing and storage of the same.

If some body can share a sample document for the receiving and storage.Then I will be highly thankful.

Hi Charu, are you still looking for info on this?

Hi charu
Just go for Suma Tab a product of diversey used for vegetable sanitation. Usage procedure is on the bottle itself.

Dear bma foods -

 

Re - Suma Tab -

 

More precisely - sodium dichloroisocyanurate, dihydrate

 

Quite popular for vegetable processing i believe, (and swimming pools [?]),  but maybe expensive ?

Dear Food forum,

 

Interesting. Do you mean something like this -

Dear Charles.c

 

We are using clo2 ready sulotion available in our city Surat (Gujarat) India @4500 ppm available clo2 and life of solution is 6 month using for our fruit and veg.processing unit

Dear Food Forum,

 

Thks yr background info.

 

I'm speculating but the commercial nomenclature for this item seems to have some chemical "flexibilities".

 

Apparently “chlorine dioxide solution” may refer to a variety of chemical products, eg –

 

Stabilised Chlorine Dioxide

Stabilised chlorine dioxide is a misleading term that is unfortunately in widespread use. There are only trace amounts of chlorine dioxide in “stabilised chlorine dioxide”. The correct description of this is, “stabilised chlorite”. The chlorite is stabilised with a buffer and peroxide at a pH of about 7. Though chlorite, or stabilised chlorite is also an oxidising agent, it is not nearly as powerful as chlorine dioxide. Chlorine Dioxide, unlike chlorite, is a gas, the term “active” chlorine dioxide is used to distinguish between the real and unreal.

There is also a great deal of confusion relating to so-called “stabilized chlorine dioxide” solutions, which have little or none of the free ClO₂ molecule, but which predominate instead in chlorite ion.

USFDA apparently use their own terminology for the above, “acidified sodium chlorite”, ASC.

I also noticed this rather impressive looking chemical stated to contain 2% ClO2 -

http://shareclean.ne...oduct/c001.html

Its use in vegetable processing is discussed here –

http://shareclean.net/food/i014.html

and some interesting production chemistry/properties are here –

http://shareclean.ne...2/chlorine.html

 

Unfortunately no detailed compositional info. is provided so as to enable further study.

 

Note that the top link does propose a specific route to stabilising significant quantities of ClO2 in solution. Maybe advertised product uses same technology ?

PS - I also noticed these two recent publications which may be of interest to veg./fruit growers, eg Sujit_Kgpian –

 

 Bactericidal effects of washing fresh-cut veg, fruit with ClO2, 2011.pdf   532.68KB   22 downloads

 fresh cut product sanitation and wash water disinfection, 2009.pdf   372.73KB   21 downloads

 

PPS - in the context of the OP, one FS query might be as what the proposed to-be-used compound actually (chemically) is ?   A second, but perhaps depending on location, might be as discussed in 2nd reference in PS regarding "processing aids vs food additives".

Thanks for chemistry
