Disclosed is a rebaudioside A crystal form 7, of which the structure is represented by the Formula I. The X-ray powder diffraction (XRPD) pattern of the crystal form 7 has the following characteristic peaks at the angles of 2θ±0.1 degrees: 4.80, 5.48, 8.42, 9.27, 11.06, 11.27, 11.86, 12.62, 13.59, 14.20, 15.07, 15.44, 17.05, 17.72, 18.13, 18.62, 19.36, 21.26, 21.95, 22.75, 23.59, 24.14, 24.73, 25.01, 25.54, 25.98, 26.56. |
