Anthocyanin content, antioxidant activity, and selected physical properties of flowable purple-fleshed sweetpotato purees

JOURNAL OF FOOD SCIENCE, 73(5), S215–S221.

By: L. Steed n & V. Truong n

author keywords: anthocyanins; antioxidant capacity; purees; purple-fleshed sweetpotatoes; rheological modeling; total phenolics
MeSH headings : Anthocyanins / analysis; Anthocyanins / metabolism; Antioxidants / analysis; Antioxidants / metabolism; Food Technology; Food, Organic; Free Radical Scavengers; Humans; Ipomoea batatas / chemistry; Ipomoea batatas / classification; Plant Extracts / analysis; Plant Extracts / metabolism; Rheology; Species Specificity
TL;DR: Rheological testing indicated that adjusting the dry matter of PFSP to 18%-21% produced purees with flow properties similar to the OFSP purees, which had polyphenolic content and antioxidant capacity within ranges reported for various purple-colored fruits and vegetables.
