Pack Weight...contents Only

[pastafreak]

...or contents plus / including container?
I bought several 500gm packs of Greek yogurt and assumed they would last x number of days based on the average amount I eat per day. I finished one this morning...there was only a tiny bit in it, and started on the second one. I'd expected the first to last through today. Out of curiosity I weighed the unopened pack and it was 475gm...the pot it comes in weighs 25gm. Meaning I'm getting 450gm yogurt, not 500. Is this right?

Weights and measures? (or whatever they are called these days)

[gingejbee]

If it says "500g e", thats the weight of the yoghurt 500 gram.
(I've just weighed a 1 kg pot of Waitrose Greek yoghurt and the whole lot weighs 1032 g).

What brand is it?

[gingejbee]

...and what is the stated weight on the pot? 450 or 500g?
Whatever it says should be the weight of the contents.

[pastafreak]

The stated weight is 500...actual weight of contents looks to be 450.
It's Lidl's Greek yogurt.

"1 The contents of the packages must not be less on average than the nominal quantity

2 The proportion of packages which are short of the stated quantity by more than a defined amount (the ‘tolerable negative error’) should be less than a specified level

3 No package should be short by twice the tolerable negative error"

This allows for errors within a specified range and for 500g, the tolerable negative error is 15g so no pot should weigh less than 470g.

Is there no indication on the pot that the weight might include the pot? eg, sweets often say "weight includes immediate wrappings".

[pastafreak]

Maybe I should write to Lidl's...after weighing 1 or 2 more packs. Maybe today's was an oddity.

I heartily wish the only thing in my life that I had to worry about was the weight of a few dribbles of yoghurt.

[pastafreak]

bhg...nope. Just checked.
Also, a serving is defined as 125gm/165cal based on the reference intake of 100gm/132 cal.

[barry1010]

Yes, write to Lidl, pasta - hopefully they'll send you some vouchers and make sure that their goods are proper weights in future.
Pubs get closed down for serving short measures, it's no laughing matter

[pastafreak]

While I agree with you, those few dribbles add up jackdaw...to feeling cheated.

I worked for a while in the quality control section of a company packing various fruits and nuts based products.

They did some products for M&S and the filling machines were always set so the packets were never underweight.

Corby, it amazes me how pre-packed fruit and veg is always (usually) the correct weight. I realise a machine must be weighing/packing the produce.

[THECORBYLOON]

In a bag of mixed fruit and nuts, I had to separate the different fruits and nuts to make sure the right ones were in the pack and their weights fell within certain percentages.

There were checks carried out on samples of some nuts to make sure there was an acceptable percentage of dark or light ones in a measured sample.

We always made sure M&S got the better quality produce.
