It could be curtains for sour milk with bottle-cap ‘sniffing’ sensor

Posted by Lisa Miles on May 15, 2019 10:06 am

Reading an article on E&T's website about the development of sensors to tell you whether or not your milk has gone bad (without having to endure the awful smell of a manual nose test) by changing the colour of the plastic cap!

What a wonderful idea! I think this should be applied to all forms of food so a sticker or a patch on the food label changes colour to let you know if it's gone bad or not! Obviously for fresh items a quick inspection will tell you if they've gone rotten but what about tinned or bottled produce when you only know what state the contents are in once you've opened it...

Schrodinger's beans perhaps? 😂

Yes I can see several uses for this. My only reservation  might be the integrity of the indicator patch if left in storage, poorly manhandled or womanhandled, prolonged temperature changes, chemical attack and corrosive effects, abuse and sabotarge in various ways.

A further development might be to glue the patches onto known rascals foreheads which change colour when the person gets aggressive......chemical changes due to pherormones

Will these bottle tops be recyclable  - or is this just another example of single use plastics being introduced because they can be

I can see some value in certain (probably medical) applications - but for a plastic milk container it seems a bit pointless

Perfect for indicating when to make sour dough and/or possibly cheese.?....

I've noticed that the bottle top gets 'ripe' long before the milk itself is spoiled, although I guess it is an early indication that things are going west. Do we need more non-disposable plastics, circuitry, batteries etc. just to satisfy what our nose alone will tell us? Looks like a solution in search of a problem. Isn't it time we had an intelligent toaster instead, a task for which electronics and sensors could actually be useful?
