The food additive alpha-galactosidase and parent mycelial microorganism Mortierella vinaceae var. raffinoseutilizer may be safely used in food in accordance with the following conditions:

1. (a) The food additive is the enzyme alpha-galactosidase and the mycelia of the microorganism Mortierella vinaceae var. raffinoseutilizer which produces the enzyme.

2. (b) The nonpathogenic microorganism matches American Type Culture Collection (ATCC) No. 20034, ¹ and is classified as follows:
