Powered Rennet
« on: January 17, 2014, 06:29:37 PM »
Since I have had issues using up liquid rennet before it expires (and I've no idea how long my local store had it on the shelf) I figured that I get some powered rennet http://www.thecheesemaker.com/products/Dry-Calf-Rennet-Powder.html It claims that it will store indefinitely in the freezer which is good. However, the recommended measurements (1/16th tsp per 2 gal) are smaller than I can reliably measure.

1) So I was wondering if I can I reconstitute it with water up to the point where I could measure it out as a 1/4 or 1/2 tsp; as long as I keep the original ratio intact? Essentially making my own liquid rennet as needed from an indefinitely fresh source.

2) If I did that, any guess what the shelf life on the reconstituted rennet might be?

Thanks!

Make it up in saturated brine, or nearly so (~23%). Adjust pH if possible to around 5.5-6.0.  If you were to add in benzoate and caramel color, you'd get commercial rennet solution. As for shelf life of reconstituted stuff, it depends on contamination potential. If your handling is clean, it will last about as long as commercial liquid calf rennet.

When I bought my first powdered calf rennet, I also bought the little measuring spoons he sells on the site.  They are for "dash", "pinch" and "smidgen" and I had to figure out exactly what those terms meant, but they work just great.

Thanks for that HKJ!  I have the equivalents written on the front of my cheesemaking folder and the inside of my favorite cheese recipe book, but neither were handy when I was typing out my reply!

While most of the cooking world uses the Imperial Units, cheese makers have long used the Hobbit's measurements.  :D

Yes, I had seen these micro-measuring spoons before. Unfortunately, some manufacturers don't adhere to those fractionals.

Norpro - 1/5 tsp, 1/11 tsp, 1/16 tsp, 1/32 tsp, 1/64 tsp.
Norpro - 1/4, 1/12, 1/16, 1/32, 1/64
RSVP - Accurate only if contents are heaped/rounded

So, since I don't know who the manufacturer is for the ones on thecheesemaker.com I got a set from amazon that was reviewed to actually measure accurately. That said, it's good to know that I can always convert to a liquid form as plan B.

Many thanks to all who replied!
