##If the rennet comes from a kosher animal which was slaughtered properly by a Jew then it is kosher as long as there is 60x the milk in comparison to the rennet.<ref>[https://en.wikipedia.org/wiki/Rennet#Extraction_of_calf_rennet Wikipedia on Rennet] points out that using the traditional method of rennet extraction one 1 gram of rennet can be used to coagulate 2 to 4 Kg of milk and the modern extraction method after concentration yields rennet that one gram of which can be used to coagulate 15 Kg of milk. Either way, this is clearly less than the ratio of 1 in 60, as [http://www.kashrut.com/articles/cheese/ Rabbi Avraham Gordimer] points out as well. Mishna Chullin 116a (according to Rashi) writes that since the rennet from the kosher animal is meat and it is being used to coagulate milk it is only permitted if there is 60 times the rennet in the milk otherwise there is a prohibition of eating milk and meat together. Shulchan Aruch YD 87:11 codifies this. | ##If the rennet comes from a kosher animal which was slaughtered properly by a Jew then it is kosher as long as there is 60x the milk in comparison to the rennet.<ref>[https://en.wikipedia.org/wiki/Rennet#Extraction_of_calf_rennet Wikipedia on Rennet] points out that using the traditional method of rennet extraction one 1 gram of rennet can be used to coagulate 2 to 4 Kg of milk and the modern extraction method after concentration yields rennet that one gram of which can be used to coagulate 15 Kg of milk.

* Why is rennet from a non-Kosher animal not nullified and rennet from a kosher animal permitted if it is less than one in sixty? The Ri Migash (cited by Torat Habayit 90a) explains that this is different than rennet from a non-Kosher animal which isn't nullified because it is a coagulating agent and is intrinsically forbidden unlike kosher rennet. Rambam (Maachalot Asurot 3:13, 9:16), Rashba Chullin 116a, and Ritva Avoda Zara 35a agree. Shach 87:35 agrees. However, the Tosfot Avoda Zara 35a s.v. mipnei and Raavad (Torat Habayit 90b) argue that fundamentally rennet from a kosher animal is the same as non-kosher rennet in that they are nullified if it isn't tasted but since the issue of meat and milk is only rabbinic if it is a cold mixture it is permitted in cases of doubt. Maharshal Chullin 8:106 agrees.</ref> In terms of actual process of how the rennet is extracted from the Kosher animal so that it should be permitted even initially is complex discussion.<ref>Chatom Sofer (responsa 81, cited by Pitchei Teshuva 87:19), Rabbi Akiva Eiger (responsa 1:207)</ref> | * Why is rennet from a non-Kosher animal not nullified and rennet from a kosher animal permitted if it is less than one in sixty?

##If the rennet comes from an animal which was not slaughtered properly it is forbidden and can't be nullified since it is the agent which solidifies the milk into cheese.<ref>Avoda Zara 35a says that a maamid (coagulating agent) is forbidden even if it isn’t recognizable and has no taste since its accomplishment of transforming the food is recognizable. Mishna Chullin 116a states that cheese made with rennet from an animal that lacked a properly ritual slaughter is forbidden. Rambam (Machalot Asurot 3:13) writes that the non-Kosher rennet isn't nullified since it is the agent used to coagulate the cheese. Shulchan Aruch YD 87:11 codifies this. The Maharshal Chullin 8:106 comes to the conclusion that even non kosher rennet is nullified one in sixty like the Raavad (cited by Rashba Torat Habayit 90b) unlike Rambam Maachlot Asurot 3:13.

Shach YD 87:35 and Magen Avraham 442:9 reject the Maharshal. Dagul Mirvavah 87:4 supports the Maharshal from Rashi. Igrot Moshe YD 2:32 disagrees with the Dagul Mirvavah's proof. Nonetheless, Igrot Moshe is lenient for the Maharshal after the fact for a rabbinic prohibition or something that is a doubt if it is Biblical. | ||
* Is Maamid a Biblical concern? The Bach assumes that it is. Shach 87:32 argues that for milk and meat it isn't since it is a cold mixture. Magen Avraham 442:9 writes that in general maamid is Biblical since it is like the prohibition is still intact. Chok Yakov 442:16 argues.</ref> | |||
