Kosher Gelatin

Question

As to the question, are hides considered meat, Horav Moshe Feinstein zt"l addressed this issue in Igros Moshe (vol:1 #37). There he writes that hides are not considered meat (to prohibit its mixture with milk) by Torah Law. They are prohibited with milk by Rabbinic law. If they are dried and processed, the gelatin that comes out is not included in this Rabbinic prohibition. Therefore, gelatin produced from kosher slaughtered animal hides may be intentionally used with milk, provided that the hides are cleaned to remove any meat residue. There are opinions that disagree with Horav Feinstein's conclusion. Notably, Horav Aharon Kotler zt"l concludes that gelatin produced from kosher hides is considered meat. However, there is room for leniency when dealing with gelatin derived from kosher hides as the gelatin has little or no taste. Therefore it can be nullified in pareve ingredients resulting in a pareve product (this does not contradict the rule ein mvatlin issur lechatchila, as it is heter.). However, gelatin from non-kosher hides retains its prohibited status. Rabbi Abadi: could you please comment on this and enlighten us. We are very confused and seek clarification from you.
