Guest guest Posted February 6, 2003 Report Share Posted February 6, 2003 I just have one simple question. Rennin comes from the calf's mucous membrane, correct? Now 'rennet' is genetically derived from rennin, correct? So my confusion is, don't the scientists need rennin to make the GM rennet? And since the original source for making the rennet is something from the calf's mucous membrane, then doesn't it still, in a removed and lesser degree, but still come from the calf? They couldn't produce the rennet without having a bit of rennin, right? Or is this wrong? I am not trying to muddy this up even more, but simply trying to clear it up in my own mind. ~ PT ~ He who would leap high must take a long run. ~ Danish Proverb ~~~~~*~~~~*~~~~*~~~~*~~~~*~~~~*~~~~*~~~~~~~~~~~~~~~~~~~~~~> , " daveo " <daveo@m...> wrote: > > Mr.Graves [sleepingtao] > > >>...rennin and rennet ARE 2 different things,<< > > Exactly!!

Guest guest Posted February 6, 2003 Report Share Posted February 6, 2003 As far as i know.. rennin is purely animal meat... rennet can come from rennin, or from other sources. the active ingredient in the rennet, is chymosin, which can be produced by some microbial enzymes and fungi. so all rennin is meaty, not all rennet, is. however, the rennet can be a mixture of the animal and non animal, can be just animal, or can be just vegetarian. The last article I put up, which was mostly a written letter by the Kraft corporation about the production of their foods, goes into a little bit of detail about it. The state several times that their version of rennet is mostly likely to have at least some animal rennet in it, if not be made completely from it. So it's not vegetarian, let alone vegan. again, i made the point earlier, some countries use only animal rennet as a matter of practice. I know thats not true of the US, but I don't happen to believe the US is the center of the universe. Many, many countries try to adhere to 'traditional' methods whenever possible, and have a populace that is much more involved in demanding access to the production of their foods. It's a double edged sword; proper labelling standards would keep things very clear; but add more words to a label already confusing to the public. Being that Kraft is a massive distributor of food in america, and a written letter from the company states that it is safe to assume almost all of their cheese has at least some animal rennet in it, I can't support any claim that 70% of the cheese in the US is made from non animal rennet. It's illogical at best. -K- --- " ~ P_T ~ <patchouli_troll " <patchouli_troll wrote: > I just have one simple question. > > Rennin comes from the calf's mucous membrane, > correct? > Now 'rennet' is genetically derived from rennin, > correct? > So my confusion is, don't the scientists need rennin > to make the GM > rennet? > And since the original source for making the rennet > is something from > the > calf's mucous membrane, then doesn't it still, in a > removed and > lesser > degree, but still come from the calf?

Guest guest Posted February 6, 2003 Report Share Posted February 6, 2003 Okay, thanks. This clears it up for me. I guess I missed the part where it stated that some forms of rennet can come from completely non-animal sources. I was thinking all rennet had a bit in it as a rule. ~ PT ~ Spring is a natural resurrection, an experience in immortality. -Henry David Thoreau, naturalist and author (1817-1862) ~~~*~~~~*~~~~*~~~~*~~~~*~~~~*~~~~*~~~~*~~~~~~~~~~~~~~~~> , " Mr.Graves " <sleepingtao> wrote: > As far as i know.. > rennin is purely animal meat... > > rennet can come from rennin, or from other sources. > the active ingredient in the rennet, is chymosin, > which can be produced by some microbial enzymes and > fungi. > > so all rennin is meaty, not all rennet, is. > > however, the rennet can be a mixture of the animal and > non animal, can be just animal, or can be just > vegetarian.

Guest guest Posted February 6, 2003 Report Share Posted February 6, 2003 My understanding is that the original GM rennet required rennin but only for the chymosin gene it contained, which actually performed the coagulating function in cheese making. Once GM was achieved in the lab, the " genomes of bacteria and yeast " continued to replicate the chymosin gene independent of the original animal source. If each new batch of rennet required additional rennin, this one fact alone would defeat their whole purpose of overcoming the supply deficiencies of rennin. Eventually, we get to " the chicken or the egg " conundrum. Some will believe it's still too closely tied to an animal product, and some will accept that it's a plant based GM product which functions like the chymosin gene in rennin. Choosing between the two is an ethical question which I won't pursue. I'll have an opinion and so can those around me, as long as they remain all in that context.

Once GM was achieved in the lab, the " genomes of bacteria and yeast " continued to replicate the chymosin gene independent of the original animal source. I see. So I guess if one was ethically predisposed to avoid anything that was made in its original production from an animal source, then even a " vegetarian " type of GM rennet would be something they might not want to eat since to obtain the chymosin gene in the first place, it had to come from a calf. I can see the ethical dilema. However for me this is not an issue I worry about. Personally I am quite content being a lacto-ovo vegetarian. > If each new batch of rennet required additional rennin, this one fact alone > would defeat their whole purpose of overcoming the supply deficiencies of > rennin. No, I understood this part. I was more asking about the original production of the chymosin gene, which you answered.
