Abstract:

Moisture absorption and moisture retention of royall jelly(RJ) extract and RJ residue were investigated under 8 different conditions of relative humidity respectively, and the variations of absorption and retention with time were also studied. The results showed that the moisture absorption of RJ extract is moderate and the moisture retention is perdurable especially in dry environment. Therefore, as moisture retentive agent, RJ extract would be well applied in the future.

Key words: royal jelly, moisture absorption, moisture retention
