Special Issue Information

Dear Colleagues,

In recent years, there has been a growing interest in alternative food processing and preservation methods that minimize the use of thermal treatments. Traditional thermal processing, while effective in deactivating microorganisms and enzymes, often leads to degradation of nutrients, sensory attributes, and functional properties of foods. Cereals and legumes, as staple foods globally, are particularly susceptible to these detrimental effects. Therefore, there is an urgent need to explore and develop nonthermal processing and preservation technologies that can extend the shelf life and enhance the quality of cereals and legumes without compromising their nutritional value.

The aim of this Special Issue is to provide a comprehensive platform for researchers to share their latest findings and insights on nonthermal food processing and preservation technologies specifically tailored for cereals and legumes. The issue aims to cover a wide range of innovative approaches, including, but not limited to, high-pressure processing, pulsed electric fields, ultrasound, irradiation, and natural antimicrobials.

This Special Issue invites researchers to submit original research articles or reviews related to the following:

  • High-pressure processing of cereals and legumes;
  • Ultrasound-assisted extraction of bioactive compounds from cereals and legumes;
  • Pulsed electric fields for microbial inactivation in cereal and legume products;
  • Irradiation technology for preservation of cereals and legumes;
  • Natural antimicrobials in nonthermal preservation of cereals and legumes;
  • Effect of nonthermal processing on the digestibility and bioavailability of nutrients in cereals and legumes;
  • Sensory and textural changes in nonthermally processed cereals and legumes;
  • Emerging nonthermal technologies for cereals and legumes.

Nitrogen-modified atmosphere technology, due to its effectiveness in pest control, is widely used in grain storage as an eco-friendly preservation method. This study compared the quality changes in unhulled rough rice (paddy) stored under nitrogen-modified atmosphere and conventional conditions. Fatty acid value (FAV), reactive oxygen species (ROS) content, coenzyme levels, antioxidant enzyme activities, and concentrations of central carbon metabolism-related metabolites of paddy were monitored during storage under different storage conditions. The results revealed that compared to conventional storage, nitrogen-modified atmosphere resulted in lower FAV and ROS levels, as well as higher pyridine nucleotides contents and antioxidant enzyme activities, including superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), and glutathione reductase (GR). Metabolomic profiling demonstrated that N2-MAS induced metabolic changes characterized by the down-regulation of 2-hydroxyglutaric acid and the up-regulation of fructose 6-phosphate, glucose 1-phosphate, glycerol 3-phosphate, gluconic acid, fumaric acid, and malic acid, which collectively contribute to reduced oxidative damage and enhanced preservation quality. These findings elucidated the mechanism of N2-MAS-delayed quality deterioration and revealed the regulatory role of the antioxidant system and central carbon metabolism. Full article
