Structural, Physicochemical, and Functional Properties of Waxy and Non-Waxy Foxtail Millet Starches.

ABSTRACT: This study investigated the structural, physicochemical, and functional characteristics of foxtail millet starches (FMSs), including five non-waxy varieties (N-HXMS, N-LXMS, N-QZHS, N-JG21S, N-BLGS) and one waxy control (W-HJGS). All FMSs exhibited polygonal granules with surface pores and an orthorhombic crystalline structure (A-type X-ray diffraction pattern). Compared with the waxy FMSs, non-waxy starches exhibited higher amylose content (32.4-34.04%), reduced crystallinity (37.01-39.21%) and short-range molecular order, and lower hydration capacity and molecular weight (1.01 × 10⁵-2.81 × 10⁵ g/mol). The non-waxy FMSs also demonstrated enhanced resistance to mechanical shear, better structural stability, stronger recovery behavior, and reduced enzymatic susceptibil
