Structural Characterization of Cellulose Obtained from Extraction Wastes of Graviola () Leaf.

Cellulose is one of the most common functional ingredients in food products and has been widely used as fat replacers and stabilizers. In the present study, the structural properties of cellulose obtained from extraction wastes of graviola (.) leaf (CWG) were characterized via scanning electron microscope (SEM), X-ray diffraction (XRD), fourier transform-infrared (FTIR), and C nuclear magnetic resonance (NMR) analyses.

Physicochemical and Textural Properties of Noodles Prepared from Different Potato Varieties.

This study was performed to investigate the quality characteristics of noodles made from four different potato varieties: Atlantic, Go-un, Sae-bong, Jin-sun, and wheat flour. Quality characteristics of five noodles were analyzed by general components analysis, cooking quality (rate of water absorption, cooking loss, and volume increase), and mechanical textural properties. Some variations existed in wheat- or potato-based noodles for the general components analysis, but no clear trend was observed.
