# It's forbidden to intentionally mix forbidden food into permissible food so that it should become nullified. <ref>Gemara Beitzah 4a. Some rishonim consider this prohibition Deoritta while others Derabbanan, see Bet Yosef Y"D 99, Shach 99:7, and Chachmat Adam 52:6 </ref>
# It's forbidden to intentionally mix forbidden food into permissible food so that it should become nullified. <ref>Gemara Beitzah 4a, Shulchan Aruch YD 99:5. The Raavad ([http://www.hebrewbooks.org/pdfpager.aspx?req=8897&st=&pgnum=24 Isur Mashehu ch. 2]) considers this to be Biblically forbidden, while the Ran ([http://www.hebrewbooks.org/pdfpager.aspx?req=14310&st=&pgnum=609 Chullin 35b]) and Rashba (Torat HaBayit) hold that it is derabbanan. See Bet Yosef Y"D 99, Shach 99:7, and Chachmat Adam 52:6 </ref>
# If a forbidden ingredient falls into kosher food one may not increase the ratio of kosher food to non-kosher in order to nullify the non-kosher. <ref> Shulchan Aruch Y"D 99:5 </ref>

# There is a prohibition of benefit to the one who intentionally causes a nullification unless there is an express permit (as certain cases do). Others however may benefit from the mixture if it wasn't done specifically for their sake. <ref> Shulchan Aruch YD 99:5 </ref>

# A mixture which was permitted because of nullification of majority and one wishes to cook it together which would make it forbidden, one may intentionally add more permitted ingredients so that there would be 60 times the forbidden ingredient before one cooks it and the cooked mixture would be permitted. <ref>Shulchan Aruch YD 109:2 based on the Raah. The Taz 109:3 and Shach 109:13 explain that the logic for this is that since the mixture is currently permitted it is permitted to add as much as one wishes even though it is preventing an forbidden item from prohibiting the mixture later upon cooking it.</ref>

# Some say that if a rabbinically forbidden item fell into a mixture it is permitted to add more permitted ingredients in order to create nullification. Ashekanzim are stringent not to do so.<ref>Shulchan Aruch YD 99:6 permits adding to a mixture with a rabbinically forbidden item in order to permit it with nullification. This is partially based on the Gemara Beitzah 4b. The Rama, however, argues that it is forbidden to do so. See Shulchan Aruch OC 677:4 who seems to forbid as well.</ref>

# If food was cooked in a pot which was previously used for forbidden food within the same day, the food is forbidden unless the volume of the food is sixty times greater than the volume of the pot. Similarly, if a hot food was mixed with a utensil which absorbed forbidden flavors, the food is forbidden unless the volume of the food is sixty times greater than the volume of the part of the utensil which entered into the food. <ref>Shulchan Aruch YD 98:4.
