<p>PURPOSE:To obtain an anthocyanin production-stimulating factor capable of increasing the production amount of the anthocyanin by adding the factor to a culture medium, when anthocyanin-producing cells are cultured, and further to obtain the medium containing the same. CONSTITUTION:This anthocyanin production-stimulating factor is released from strawberry culture cells, when the culture cells are cultured, and has following characteristics: (a) the factor has such heat resistance as not inactivated even when sterilized with pressured steam at a temperature of >=150 deg.C, (b) the factor has a mol.wt. of 500-1500, when compared with a standard substance having a known mol.wt. by a gel filtration method, and (c) the anthocyanin production amount of the strawberry culture cells is increased when the strawberry culture cells are cultured in a medium to which the anthocyanin production-stimulating factor is added, in comparison with the culture in a medium to which the anthocyanin production-stimulation factor is not added. And a medium contains the same.</p> |
