As the lactic acid bacteria, it is preferable to useLactobacillu s sake D-1001 (NIBH Deposition No.11708, IPOD FERM BP-08544) together with Lactococcus lactis IFO 12007. As the fishes employed as the starting materia l, salmons, trouts or cods are preferable. Among all, a remarkable effect can b e observed by using fishes containing astaxanthin.
