Title:
SWEET POTATO PLANT AND ANTHOCYANIN-BASED PIGMENT COMPOSITION DERIVED FROM SWEET POTATO
Document Type and Number:
WIPO Patent Application WO/2020/179719
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an anthocyanin-based pigment composition which is derived from a sweet potato, and which has color developing characteristics that exhibit a vivid red color tone and has excellent compound stability.  The present invention pertains to a sweet potato plant which contains a large amount of a pelargonidin-based anthocyanin compound as a pigment component and has the characteristics described below: (1) the sweet potato plant belongs to a mating population of Kyukei 89360-8 and Kyukei 294, or a progeny population thereof; (2) as the composition of an anthocyanin-based pigment contained in a tuberous root, the ratio of the peak area of the pelargonidin-based anthocyanin compound to the peak areas of all the anthocyanin compounds in HPLC analysis is 70% or greater; and (3) as the composition of the anthocyanin-based pigment contained in the tuberous root, the ratio of the peak area of the anthocyanin compound having a hydroxycinnamic acid-modified group to the peak areas of all the anthocyanin compounds in the HPLC analysis is 50% or greater.
