3,439. Tevel Mixed With Chullin

Hilchos Maaser 8:2

Let’s say that untithed produce (tevel) got mixed with the same species of secular produce that has been rectified (chullin). In such a case, it cannot be nullified based on its taste being undetectable because you can’t tell the taste of the tevel from the taste of the chullin. If one has other produce, he should take the terumah and tithes for the tevel from it in the proper proportions. If he doesn’t have other produce, then the mixture remains prohibited until he tithes it. When he tithes it, he gives up a portion of the chullin that was rectified equal to the terumas maaser that he takes from the tevel.

Hilchos Maaser 8:3

Pursuant to the previous halacha, if 100 seah of tevel gets mixed with 100 seah of rectified chullin, he must take 101 seah from the mixture. What he puts aside is considered tevel, leaving 99 seah of rectified chullin. We see that he has lost a seah of chullin. Similarly, if terumah wasn’t taken from the tevel, he must also give up an amount of the rectified chullin equal to the terumah and terumas maaser. The reason he loses the seah of chullin is so that he shouldn’t think that he put aside the 100 seah of chullin and left the 100 seah of tevel. Likewise, if the volume of tevel was more or less than the volume of chullin, he takes an amount equal to the tevel plus an amount equal to the terumas maaser from the chullin, or if terumah wasn’t taken from the tevel, an amount equal to the terumah and the terumas maaser.
