Article Abstract

This study investigated the effects of subsp. 1.2472 (L)-, 1.2718 (S)-, and thermostable HCUL 1.1901-1912 (T)-fermented rice flour with inoculum levels of 3-11% (/) on rice bread staling. Optimal staling resistance was achieved, as follows: 9% L-fermented rice bread (LRB), 7% T-fermented rice bread (TRB), and 5% S-fermented rice bread (SRB). Lactic acid bacteria-fermented rice flour significantly enhanced hydration properties. LF-NMR analysis revealed that T (strongly bound water) and T (weakly bound water) relaxation times decreased, while T (free water) increased with prolonged storage. Fermented-rice-flour groups had significantly more strongly bound water than the control group on 7 d. The optimized formulations exhibited exceptional volumetric stability with specific volume change rates of 17.63% (LRB), 17.60% (TRB), and 19.58% (SRB), coupled with maximal porosities of 10.34%, 9.05%, and 9.41%, respectively. This study provides a theoretical foundation for improving rice bread's anti-staling properties.

Red yeast rice (RYR) is commonly used as colouring and flavouring agent in foods throughout East Asia. RYR contains monacolin K, a compound known to lower blood lipids level, which has led to its use as a health functional food in Korea. Additionally, RYR is frequently used as a food ingredient and is incorporated into processed foods such as bread and makgeolli, a traditional Korean alcoholic beverage.

Introduction: The sodium-to-potassium (Na:K) ratio in the diet is a critical biomarker for cardiovascular and metabolic health, yet global adherence to recommended levels remains poor.

Objectives: The objective of this study was to identify dietary determinants of the dietary Na:K ratio and its associations with micronutrient intake and diet quality.

Methods: An observational cross-sectional survey was conducted in a representative sample of manufacturing workers through a combined stratified proportional and two-stage probability sampling plan, with strata defined by company size and industrial sector from the state of Rio Grande do Norte, Brazil.

The lack of network structure in rice dough imposes limitations on the production of corresponding gluten-free (GF) food. This study investigated and evaluated the network structure constructed by the interaction of soybean 7S globulin (7S) with rice proteins (RPs), and the improvement of dough. These structural modifications were fully validated by the rice bread system.
