Hawking Radiation & Parity Imbalance: Matter vs. Anti-Matter

[Coderider]

Does Hawking radiation account for the parity imbalance between matter and anti-matter?
Do Black Holes create matter?
If a matter/anti-matter pair materializes on either side of the event horizon of a black hole:

1) if the matter particle is on the inside of the event horizon, the mass of the black hole increases, Its anti-matter twin will collide with a particle of matter and annhihilate with a burst of energy. The area around the event horizon should be very radioactive.​

2) If the anti-matter particle is on the inside of the event horizon, the mass of the black hole decreases? (isn't this a violation of the conservation of energy? The energy would not be able to exit the black hole. The mass of the black hole should increase). Its matter twin will increase the mass of matter surrounding the black hole. (could this be how galaxies are eventually created? The particles combining to form Hydrogen? Over time, this accumulation of mass could create massive nebulas of gas, leading to star formation.)​

No. Whether the antimatter or matter particle is the one absorbed by the BH, the effect is still the same: the BH loses mass.
