When did enzymes appear in dishwasher detergents?

Speaking of Fairy dishwasher detergents, there was also Fairy 'Tab-in-Tab': compressed hard biological tablets with an indentation, in which a modicum of blue powder detergent resided. This was to act as a quick dissolving pre-soaker. I quite liked those.

Haven't seen those Fairy 'Tab-in-Tab'detergent before.

Haven't they disappeared and become the new fairy capsule?

I have an issue with my Miele dishwasher and fairy tabs it seems they make more froth than Finish and you can hear the pump running dry if I notice it when in the kitchen I throw in a kettle of water and its ok from then but if I am not going to be about I use a Finish tab instead .

The hard Fairy 'Tab-in-Tab' tablets were indeed replaced by those awful pods.

I've been wondering why these pods seem to foam up so much. Do they have anionic surfactants in them?

I thought automatic dishwasher detergents were supposed to be low-foaming, hence the use of non-ionic (low foam) surfactants?
