The great tomato ketchup swindle(cheating supermarkets)

[SalvadorDalek]

We have a plastic squeezy tomato ketchup bottle which when empty we top up from a glass bottle. The plastic bottle is 470g
Today it needed filling up so I got a glass bottle of ketchup (Sainsburys chepo) which was 560g so I decanted it into the plastic one thinking I would have 90g left over
To my horror the ketchup from the larger bottle fitted into the smaller one.
Is someone fiddling the gramage of ketchup and syphoning off the excess? Are the supermarkets fiddling the weights to make more money?

Can supermarkets be trusted to give us the correct weights of foodstuffs and when was the last time you weighed your Branston sandwich pickle to see if it was correct?

Be alert people I think they are going to be more devious in the coming year

is it not the net weight? ie including the container it is in

"Net weight" means not including the container.

This could make the front cover of The Express.

But only if we could get Lady Diana into the story somehow

Do you take Waitrose carrier bags to take your shopping home from Aldi?

[sigh]

I love Mumsnet.

To your horror?

Perhaps 560g includes the weight of the bottle.

Or the stuff in the glass bottle is a heavier product.

You could call Trading Standards. That's what they are for.

560g won't include the weight of the bottle, that's madness, or else they would all be making thicker and thicker glass bottles with less and less ketchup inside.

It's all about density. This is clearly a superior product, packed full of tomatoes and lycopene and shit.

Thanks for explaining net weight - i actually never knew properly what it was.

I remember heniz being done for this in the last couple of years, report them!

I purchased 1lb of sirloin steak from Sainsbury and when I weighed it it weighed 12 OZ.

Lynll that terrible

Superior ketchup has shit in it??

OP is comparing mass to volume. Not the same thing at all.

Actually I have noticed that Sainsburyt's cooking choc is usually over weight.

Good cause if I need 200g and the 200g bar weighs more then there's a square for me to eat

Equally Heinz may be giving the Op extra ketchup, rather than sainsbury's selling him short?

My glass is half full.

I thin that this is down to the squeezy bottle having a bit of give in it. Those bottles are all squeezed in when you buy them, then they get a bit puffed out as time goes on, with all the squeezing?

you have inspired my new years resolution to make sure that NOONE short weights me in future. Thank you OP for bringing this to my attention, i can now see a new obsession brewing

I will report back with my findings....

i do know that there is a tolerance on weights, perhaps +/- 5% although probably more......

Am I the only one thinking life's too short to decant your ketchup from one bottle to another lol!
