Oh, and don't add it to the milk! Just give them a concentrated solution in water. They will need milk, and the milk needs to be heated to the required temps BEFORE the junket is added.

Thank you so much

Yes, the enzyme prac. is here again for the new Year 12's.
I found all the supermarkets (let the fingers do the walking!!) now stock junket tablets. IGA was the only one to sell the powder.
Powder was $10.51 and tablets was $3.49.

To follow on with the thread. Yesterday I used 40mls of room temperature distilled water and 4g.of the powder.For those of you who only have tablets, I think I crushed 3 tablets in 40/60 mls of water. I am not at school at the moment so can't look it up.There is no reaction with this solution(until it is heated!) so it will keep for a few days. Hope this is of help to some of you who perhaps are reasonably new in the job.

We use the powder as we go through rather a lot each year as the action of temperature is used as an individual assessment task for our Yr 12.
We have had up to 60 bio students each needing their own little jar. We found the powder worked out cheaper in the long run for us and lasts several years.

I have measured out 1/4 teaspoon (.7 grams, about the weight of a tablet) into separate 50 ml specimin jars, to this they add 50 mls water and then use 1 ml of the junket solution in 10 mls of milk. Usually they do about 6 different temperature and 3 or 4 test tubes at each temperature so there is way enough solution in each jar with some to spare.

The powder/water solution keeps for several days as they need to do the assessment task over at least 2 lessons to get enough runs and variables.

We have given up on the junket prac - we now use yeast solution - soak filter paper 'confetti' with it and use those for the pracs.. or potatoes..
so much easier..

Does anyone know if the powder has a use by date? I need to purchase some more and it works out much cheaper long-term to buy the 150g ($62.50 incl postage) bag than the 10g vials (x2 $14.20 incl postage) but there is no use buying it in bulk if it will stop working before we use it up. 20g has lasted us about 3 years I think, maybe 4, so 150g would last us a very long time! Otherwise, if any local (Tamworth) labbies are interested in sharing a bag (50g each?) that might work too...

We have been getting our junket from Franklins and was told it was kept at the front desk because the container is so small people were stealing it!!

people were stealing it!

Wonder what on earth they think they're getting when they steal it??

We just bought 2 packets from Coles in Port Macquarie. It is in the dessert section, down the bottom shelf.

just curious, what does a packet cost, and how many grams is in a packet?

Hi, I recently bought junket from Woolworths in Goulburn, I think it was approx $3.99 for a packet of 12 tablets. Each tablet makes 500mls of junket.

12 tablets = 6g powder so that works out to be ~$4/6g = $100/150g whereas buying it directly is $62.50/150g. I think I will just get the bulk pack.

Thanks for the info

Our bulk pack lasted about 3 years and worked fine at 3 years.
You also save having to crush the tablets when you get the powder so it disolves better.

Junket time of year again and I have run out of my powder that I got from "Just Junket" several years ago and there is not quite enough for the assessment task
I tried their website but get an error message saying the website cannot be found and their phone number doesn't work either.
Does anyone know if they are still in operation and any contact numbers. The number I tried was 08 82449571

Coles and Woolies both stock junket tablets here.

yes woolies has them in their pudding and jelly section.

We bought them from St Marys Woolies today.

I Know you can get the tablets, but we have used this enzyme prac as our Year 12 assessment task for the last 8 odd years.
Each student is given 0.7gms of powder in a specimen jar which they make up to 50 mls.
They then use this solution at a ratio of 1ml to 10 mls milk to investigate the effect of temperature on the actions of enzymes.
The tablets contain different proportions of the ingredients so to keep the prac assessment consistent for all students I was wondering if the powder was still available.
I should have just enough for this year, there is one jar for each student, if they stuff up bad luck! and may go to a tablet each next year. We started using the powder when tablets became unavailable.

I have that phone number for 'simply junket'

I found powder at IGA, not my local woolworths.
