Prepared dishes are becoming an increasingly important part of diets, while most studies focus on the flavor. In this study, the moisture loss induced by structure changes of precooked beef during freezing-thawing-reheating process was investigated. The myowater trapped and released by 'myenteric channels' and 'water reservoir' were observed by integrated multiple microstructure and water distribution visual analysis. X-ray results showed an increase in total porosity and the close porosity transfer to open porosity during freezing-thawing-reheating. The weight loss of frozen-reheated (FR) and frozen-thawed-reheated (FTR) samples was 6.34% and 7.69%, respectively. Although freezing-thawing did not significantly affect the moisture loss, magnetic resonance image (MRI) showed that the 'free water' temporarily existed in interfibrous spaces after thawing and leaked out during reheating. Directly reheating avoided the myowater redistribution and muscle extension mediated, which reduced moisture loss. These results provide a reference for quality control of prepared dishes during the industrial supply chain.

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.

The spoilage of bulgur, characterized by a distinctive off-odor, poses a significant challenge to the bulgur industry, resulting in an annual production loss of 10 %. The tempering process plays a critical role to prevent this problem. This study investigated spoilage under high-moisture tempering conditions (15-27 % moisture, 25, 35 and 45 °C, 0-12 h), focusing on off-odor formation, volatile compounds and microbial activity.

The microbial and physicochemical changes of hawthorn sticks in four packaging, including the traditional metallic twist tie packaging with biaxially oriented polypropylene and cast polypropylene, and vacuum packaging (VP), deoxygenated packaging (DP), and plastic packaging (PP) with polyamide/polyethylene (PA/PE) composite film, were compared during the storage at controlled temperature and relative humidity. After 60 days of storage, the control group showed an unacceptable increase in molds (0.65 log CFU/g) and maximum physicochemical losses (25% of moisture content and 72.

Turmeric () is primarily traded in dried form; preserving its bioactive compounds and quality through optimal drying methods is critical. This study evaluated the effects of various drying techniques-sun drying (SD), convection oven drying (COD), vacuum oven drying (VOD), infrared drying (IRD), microwave drying (MD), and freeze drying (FD)-on turmeric rhizomes slices. Key parameters analyzed included moisture loss, color, total phenolic content (TPC), curcumin content, antioxidant capacity and essential oil (EO) content and composition.

Snow is an important insulator of Arctic soils during winter and may be a source of soil moisture in summer. Changes in snow depth are likely to affect fine root growth and mortality via changes in soil temperature, moisture, and/or nutrient availability, which could alter aboveground growth and reproduction of Arctic vegetation. We explored fine root dynamics at three contrasting treelines in northwest Alaska.
