Article Abstract

Huangjiu is a traditional Chinese fermented alcoholic beverage made from glutinous rice. The quality and flavor profile of Huangjiu are intricately linked to the intrinsic properties of the rice used. While research on rice for Huangjiu emphasizes macronutrients such as starch and protein, little is known about the characteristics of small molecular metabolites. Here, we characterized the macromolecular profiles of three glutinous rice varieties suitable for Huangjiu brewing, and matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) was applied to map the distribution and relative abundance of small molecular metabolites within the rice grains, providing insights for the development of specialized rice varieties for brewing.

Japonica is considered one of the better tasting varieties, so it is important to balance the quality and taste of japonica rice produced by moderate processing. This study analyzed the changes in bioactive components, heavy metal elements, and sensory quality of northern japonica rice after gradient milling, and constructed a comprehensive quality evaluation model for japonica rice with different degrees of milling. The results showed that as the degree of milling (DOM) increased from 0% to 10%, the bioactive components in japonica rice decreased, with dietary fiber (3.

Dataset of rice growth for saline-alkaline tolerance screening.

Data Brief

October 2025

Graduate School of Integrated Sciences for Life, Hiroshima University, Higashi-Hiroshima, Hiroshima, 739-8528, Japan.

This dataset exhibits the growth profile of multiple rice varieties, most of which include world or Japanese rice core collections, under saline-alkaline conditions through two screenings. In both the first and second screenings, the rice plants were hydroponically cultivated for 4 weeks under normal conditions and then subjected to control or saline-alkaline conditions for 2 weeks. In the first screening, dry weight, dry weight ratio, and SPAD values were measured, and candidate varieties possessing saline-alkaline tolerance (7 varieties) or sensitivity (3 varieties) were selected based on the dry weight ratio.
