Suitability of Purple-Fleshed Sweet Potato Clones for Ingredients of Chinese Buns (Buns)

Abstract

A form of tuber known as a sweet potato includes bioactive substances in addition to carbs, vitamins, minerals, and dietary fiber. Purple-fleshed sweet potatoes have been heavily marketed as functional foods due to their anthocyanin content. Different textures can be found in the three types and two clones of sweet potatoes used as a base for buns. In comparison to the other 3 kinds, the textures of RIS 10043-02 and MSU 10003-07 were harder, more cohesive, and chewier. The high values of hardness (5.78N), springiness (73.77%), and cohesiveness contributed to the high chewiness value of the buns manufactured from Antin 2 (257.52N) (0.63N). The L*, a*, and b* values of the generated buns decrease with increasing anthocyanin concentration in the raw material, and the panelists’ preferences for color also increase. For the four sensory evaluation criteria of the buns manufactured from five different sweet potato clones, the scores varied from 3.64 to 4.08. It seems that the MSU 10003-07 clone, followed by Antin 2 and Antin 3, was the panelists’ favorite bun.
