Article Abstract
The promotion of industrial-mode production of Nannf. var. (Nannf.) L. T. Shen () has expanded the demand for the postharvest storage of fresh roots. Further research is needed to establish comprehensive methods to evaluate the impact of storage conditions. This study simulated the storage process of roots at near-freezing temperature [NFT (-1 °C)] and traditional low temperatures (-6 °C, 4 °C and 9 °C) for 40 days. At different storage stages, correlation analysis was conducted using quantitative data on 20 parameters, including sensory quality, active components, antioxidant capacity and physiological changes. Appearance and principal component analysis could distinguish between fresh and stored samples, while NFT samples on the 40th day of storage were similar to fresh ones. Correlation analysis indicated that NFT storage could maintain the sensory quality by increasing the antioxidant enzyme activity and active components, reducing the accumulation of reactive oxygen species and malondialdehyde and reducing the activity of browning-related enzymes and cell-wall-degrading enzymes. These findings highlight the importance of the overall quality evaluation of fresh roots and emphasize the potential to improve fresh root and dried medicinal material quality by regulating storage conditions such as temperature.

Drying is a critical unit operation in food processing, essential for extending shelf life, ensuring microbial safety, and preserving the nutritional and sensory attributes of food products. However, conventional convective drying techniques are often energy-intensive and lead to undesirable changes such as texture degradation, loss of bioactive compounds, and reduced product quality, thereby raising concerns regarding their sustainability and efficiency. In response, recent advancements have focused on the development of innovative drying technologies that offer energy-efficient, rapid, and quality-preserving alternatives.

Introducing underutilized legumes as plant-based protein sources to daily meals is an approach to address the increasing demand for alternative proteins. However, legumes often exhibit off-flavors and aromas, causing negative consumer perceptions. Lupins are an underutilized legume that is becoming popular as a plant protein source due to their high protein, fiber, and low starch contents.

The hop plant is gaining interest in the food, pharmaceutical, and cosmetics industries due to its abundance of secondary metabolites. However, branches and leaves, despite their antioxidant potential, are typically discarded. To valorize these components as functional ingredients they were dried, milled into hop powder (HP), and used to enrich bread.

This study presents a biopreservation method using sourdough co-fermented with Fructilactobacillus sanfranciscensis and Propionibacterium freudenreichii, optimizing conditions to 220 hydration and 24 h fermentation. The composite sourdough bread quality was evaluated through physicochemical, storage, sensory, and microbial tests, with mechanisms analyzed based on microstructure, rheology, and dough structure. Results showed that: first, the composite sourdough enhanced bread physicochemical properties, increasing volume, height-to-diameter ratio, elasticity, and resilience, while reducing baking loss, hardness, chewiness, and adhesiveness.

Domiati cheese, one of the most popular soft white cheeses, is particularly susceptible to microbial deterioration due to its high moisture content and low salt concentration. This study assesses the effectiveness of a new edible coating made from carboxymethyl chitosan nanoparticles loaded with pomegranate peel extract (CCS LP) in increasing the shelf life of Domiati cheese. The study compares CCS LP's performance to pomegranate peel extract (PPE) and carboxymethyl chitosan nanoparticles (CCS NPs) alone.
