The Tesco Baked Bean Theft

Coopdivi

You're probably cutting back on the wrong thing. The Aldi baked beans in my store cupboard contain 0.6% fat. I don't suppose Tesco's version will be much different.

Still thanks for the post anyway. It gave me a good laugh.

It's not just Tesco's OP.

I always weigh out my portions and all brands I've weighed come up light. I've yet to find a can where the allowed margin for error is in my favour.

It's because the shop staff put them behind for themselves :rotfl:

They use to be approximately 903 beans in a tin but they now reduced that to 789

You must be buying the less fattening ones, the less there are the less fat you get.;)

and just how is the average person supposed to know the e means approximate!!!

Any average, educated person should know this. It's basic mathematics!

jamespir

you were that bored you decided to weigh the contents of a tin of baked beans

omfg how sad is that


i liked the way you tried to justify by saying you was on a diet

tandraig

basic mathematics? E + approximate?
confused here
enlighten me someone!
actually - I went to secondary school and us girls were considered too thick to do maths
but I did them at college for computer course and at OU level for pyschology course - but I dont think I have come across E equalling approximate.
thought it was Mc squared!

'e' = estimated.

It seems 12 g is within tolerance:

http://en.wikipedia.org/wiki/Estimated_sign

For a net weight of 420 g the tolerance is up to 3 % tolerable negative error so it can be up to 12.6 g out.

Otherwise go for A10, circa 3 kg tins with a tolerance of 1.5 %. You'd 'save' about 70 g of beans on average.;):D

About 1/3 rd of a portion. :)

Hi everybody, this is my first post so apologies for any mistakes.

I'm wondering if modern packing technology is far more accurate than when the regulations were formulated, allowing them to consistently pack slightly under weight but still stay within the tolerances allowed.

mark55man

first post wishbone but I think you are absolutely spot on

there is a whole industry behind process control limits, tolerances, and there is a whole postrgraduate industry in the maths around normal distribution

It is entirely credible that modern technology is now capable of packaging within 1% (probably will choose to do it so 1 tin in 1000 is outside (3 sigma), or maybe 1 in a million (6 sigma) so MR T sets average at 98%, then most of the time it is good (but still 2% less than it says on the tin) and they make an extra 2% profit.

The odd time it is under spec, well (excuse me OP) I can't see many circumstances that involves anyone weighing tins of bean, so the odds of them getting caught are approaching zero

This whole thread must be a joke, right? You're actually debating a tin of beans?
