Carmine- the piskei teshuva brings down befeirush that it is permitted. However, the pri megadim says chazusa belo taama milsa hi.
Based on this, most modern kashrus agencies do not allow carmine.Used to be a problem with some cranberry juices.
Shellac- not real chazusa, batul berov. Rabbi Blemenkrantz was not happy with this kulah being universally accepted, but without it it’s hard to make good candy.
The question is by the lard, neicha bei means that neicha it tastes better or neicha bey an issur was done. I actually forgot what we say here. forgot about that taz about fat tho, thanks. I heard the same thing about a rice with milk in the flavor packet mixture cooked in a fleishigs pot- the milk was avidi letaami but no real taste so batul as less than shishim.
correct about the Rav Akiva eiger, although the magen avraham by pesach implies this is not allowed by chometz- not sure where it was in my cllalei issur veheter cheat sefer.
Steam jackets directly pipe in heat from other parts of factories. Serious kashrus concern based on the steam treifing the pipes.
