Dear carine,

I would hv thought this normally covered within the routine product spec.. A typical quality spec. might include something like -

The product possesses a typical flavour of ice, no off-flavours allowed.
And similarly for odour.......

Obviously, a product having the above characteristics is then classed as satisfactory.

Colour could be done similarly however, from memory, there actually is a standard numerical lab procedure for water for EC purposes. (especially if you wish to invite further customer discussion :smile: ?).

If you try tasting/smelling water with 6ppm of chlorine in it, you will know why the question might be relevant. :biggrin:

If you wish to get more descriptive and/or quantitative, can be done but a lot more effort probably involved, just like normal food commodities.

Dear Charles:

That means i can check the chlorine content to conform the odour/ favor of ice, rite?

For the colour can we identfy by visual? what is standard numerical lab procedure??

No, was just an example. :smile:

Ice not my detailed familiarity but IMEX the usual basic specification is that it must be produced from water of potable (drinking) standard. Presumably the ice should then have similar organoleptic qualities when evaluated. (not quite so sure about ice colour which may emphasise water impurities?)

On above basis, after a little googling (see 2 attachments below), I can suggest -

EC: Odour / flavour / colour – “Acceptable to consumers and no abnormal change”

Indian: Odour – “Unobjectionable, Flavour – Agreeable, Colour – max 5 hazen units” ( tolerance / method given).

These standards are obviously subjective but nonetheless probably representative.

If yr customer has his own specific requirements, he will no doubt inform you if other than the above style. This is why one usually produces a specification. :smile:

Dear Carine,

Basically looks OK IMO for qualitative purposes.

2 comments –

Not quite sure what the column “Colour Code” means ? Yr own standard maybe.?

You might consider captioning the form as Sensory Evaluation of Ice Form. It also usually looks more professional if you give it a ref., eg X57 (suggests you hv more than 1 form :smile: ).
