Are you allowed to mix animal rennin and milk for experimental purposes?
Is it under the prohibition of cooking meat and milk?

Is their heat involved?February 28, 2013 12:47 am at 12:47 am #933416
Rennet can be seen as a davar hadash, according to many opinions.February 28, 2013 1:20 am at 1:20 am #933417
Rd, is it the same machlokes as regarding gelatin?February 28, 2013 1:53 am at 1:53 am #933418
Yes, same as gelatin.
And since this is for research purposes, there would be more grounds to be matir.February 28, 2013 2:02 am at 2:02 am #933419Ðash®Participant
For thousands of years, Kosher cheese was made with rennet from Kosher animals. The rennet itself is Parve.February 28, 2013 2:34 am at 2:34 am #933420
I thought cheese was made without heat.
Rd, why would an issur d’Oraisa, if bishul was involved, become muttar for research?February 28, 2013 3:10 pm at 3:10 pm #933421
It all depends on how you view the rennet.
In a case of research, there may very well be more grounds to hold that the rennet is a davar hadash, and therefore, like gelatin.February 28, 2013 3:40 pm at 3:40 pm #933422benignumanParticipant
Why would the status of the rennet change if its purpose is for research? Is the rennet used for research different than the rennet used in food production?February 28, 2013 3:41 pm at 3:41 pm #933423haifagirlParticipant
Can’t you use FPC instead?February 28, 2013 3:41 pm at 3:41 pm #933424truthsharerMember
It won’t be a dioraysa anyway unless you have kosher near and kosher milk.February 28, 2013 5:14 pm at 5:14 pm #933425twistedParticipant
DY for most cheese, the milk is held at 90F, even through the renin pitch.February 28, 2013 11:31 pm at 11:31 pm #933426shnitzyMember
What kind of experimental purposes? (curious)March 1, 2013 1:06 am at 1:06 am #933427
Twisted, I assumed so, so there would be no issur even there’s kosher meat and milk, since the only issur of mixing is through bishul (unlike eating, where there’s an issur d’rabbanan to eat a mixture).
The research distinction (rd) is what makes no sense to me.
