Article Abstract

This study aimed to compare the changes in the quality characteristics of air-fried (AF) shrimp meat and deep-fried (DF) shrimp meat at different frying temperatures (160, 170, 180, 190°C). Results showed that compared with DF, the moisture and fat content of air-fried shrimp meat (AFSM) was lower, while the protein content was higher. At the same frying temperature, the fat content of the AFSM was 4.26-6.58 g/100 g lower than that of the deep-fried shrimp meat (DFSM). The smell of the AFSM and DFSM was significantly different from that of the control group. The results of the electronic tongue showed that each of the two frying methods had its flavor profile. Gas chromatography-ion mobility spectrometry (GC-IMS) identified 48 compounds, and the content of volatile compounds detected in AFSM was lower than that in DFSM. Among them, the highest level of volatile compound content was found in the DF-190. E-2-pentenal, 2-heptenal (E), and methyl 2-methyl butanoate were identified only in DFSM. In addition, a total of 16 free amino acids (FAAs) were detected in shrimp meat. As judged by sensory evaluation, the AFSM at 170°C was the most popular among consumers.

Pu and Sr are highly important radionuclides in the environment, which can accumulate in the human body through the food chain and cause radiation exposure. With the continuous discharge of treated nuclear contamination water from the Fukushima Daiichi nuclear power plant, it is crucial to investigate and monitor the levels of Pu and Sr in seafood. However, it is still a challenge to determine Pu and Sr in seafood at environmental levels, owing to their extremely low concentrations, labor-intensive and time-consuming pre-treatment for large-sized samples.

Given rising consumer demands for meat safety and quality assurance, developing an intuitive, cost-effective, and user-friendly sensor platform for real-time monitoring of perishable meat freshness is important. Herein, this study developed an innovative chitosan/agarose/blueberry anthocyanin (CS/AG/BA) hydrogel label system for visual real-time freshness tracking of perishable proteins through smartphone-assisted colorimetric analysis. Through systematic optimization of CS/AG compositional ratios (3:7-7:3) and pH conditions (2.

Developing sustainable and multifunctional intelligent packaging systems has emerged as a highly promising approach to reducing plastic pollution, minimizing food waste, and enhancing food safety. In this research, a biodegradable intelligent active packaging with a dual pH-responsive system was created by incorporating fat-soluble curcumin (CUR) and water-soluble roselle anthocyanins (RSA) into core and shell, respectively, of starch-based fibers using emulsion electrospinning. Octenyl succinic anhydride starch/polyvinyl alcohol complexes functioned as both fiber wall materials and emulsifiers, stabilizing double-loaded nano-emulsions (88.
