This study investigated the effect of 0.8% (m/v) kojic acid treatment on changes in the microstructure and myofibrillar protein of duck meat covered with oxygen‐permeable polyvinylchloride (PVC) film (9 ± 0.5 µM) during superchilled storage (−1.65 ± 0.5°C). The superchilled samples exhibited wider gaps between muscle fibers at 5 weeks storage compared with kojic acid–treated groups. Based on the variation of water status, the water‐holding capacity decreased significantly (p < 0.05), and bound water and immobilized water were gradually converted into free water during superchilled storage. For kojic acid–treated samples, however, no major changes were observed with respect to muscle structure, water status, and protein degradation at 6 weeks. The 0.8% (m/v) kojic acid treatment increased the water‐holding capacity, reduced carbonyl content and protein degradation, and decreased the α‐helix contents loss of myofibrillar proteins. Kojic acid treatment effectively protected myofibrillar protein structure from being destroyed during superchilled storage, suggesting that this method was a good way to reduce protein oxidation and prolonged its shelf life.

“…Nutritional metabolic diseases are the general term for nutritional diseases and metabolic disorders or disruptive diseases, such as excessive accumulation of fat, fatty liver and cirrhosis (Zhang and Xie ,2020). This is due to excessive, insu cient or unbalanced certain nutrients in the sh, resulting in excessive nutrition, de ciency or abnormal metabolism (Lin ,et al,2024).…”

“…Epinephelus coioides (Epinephelus coioides) is an important marine product creature in China with high economic value. Due to its huge market demand, with the continuous development of arti cial breeding technology, it has become an important economic sh in China's coastal areas (Zhang and Xie ,2020;Ph ,et al,2022). This article aims to provide a reference for the in-depth development and utilization of grapefruit polysaccharide in the eld of aquatic products by exploring the impact of grapefruit polysaccharide on reducing grouper fat deposition and keep liver health.…”

High density and intensive aquaculture of fish often lead to some nutritional and metabolic related diseases. This experiment was designed to investigate the effect of Pomelo Polysaccharide on reducing fat deposition. Five groups of feeds were prepared: control group, low-fat diet group (7.57% fat content), low-fat diet with pomelo polysaccharide group (TDF1 group), high-fat diet group (15.48% fat content), and high-fat diet with pomelo polysaccharide group (TDF2 group). Orange-spotted groupers after 8 weeks of rearing, samples were taken to analyze the growth performance, nutrient composition, liver morphology, enzyme activities and the expression of immune-related genes in liver tissues. The results showed that the weight gain rate (WGR) of groupers in the low-fat diet group was significantly lower than the control group (P < 0.05), while the TDF1 group and TDF2 group were higher than those in the low-fat diet group and high-fat diet group, respectively. Liver damage occurred in the low-fat diet group and the high-fat diet group, while the TDF1 group and the TDF2 group showed improvement in liver tissue structure damage, and the liver lipid droplets in the TDF 2 group decreased significantly compared with the high-fat diet group. Moreover, the TDF2 group significantly inhibited the up-regulation of inflammation and apoptosis-related genes IL-1β, IL-8, caspase-3, and caspase-8. These results indicate that the addition of pomelo polysaccharide can reduce the fat deposition in the liver caused by feeding high-fat feeds, and can have a certain effect on the enhancement of immune function and improve the health of liver of groupers.

“…Similarly, in the post-rigor phase, autolytic degradation causes a rupture in the lysosome and cathepsin are released from the lysosome into the cytosol [13]. Cathepsin B hydrolyzes myofibrillar proteins into smaller polypeptides chains [14,15]. The cathepsin was reported to decrease the shear force of grass carp (Ctenopharyngodon idella) fillets by degrading the muscle texture during post-mortem storage for 21 days [16].…”

Texture is an important sensory attribute for overall quality and consumer acceptance of prawns. However, texture is affected during cold storage due to the proteolytic activity of endogenous proteases, resulting in poor quality and a short shelf life. The objective of this study is to determine the inhibitory effects of Annona muricata leaves extract (AMLE) (0, 3, 10 and 20%) on the trypsin, cathepsin B and collagenase activities extracted from the cephalothorax of Macrobrachium rosenbergii. In addition, the textural changes in M. rosenbergii during 20 days of cold storage (4 °C) were also determined. M. rosenbergii were soaked in four different treatments: 0, 3, 10 and 20% AMLE and 1.25% sodium metabisulphate for 10 min at 4 °C. Protease activity was significantly (p < 0.05) reduced at 10 and 20% AMLE. Similarly, cathepsin B showed a significant (p < 0.05) low after treatment at 20% AMLE. The maximum inhibitory activity of trypsin was achieved at 20% AMLE and the standard inhibitor (Tosyl-L-lysyl-chloromethane hydrochloride (TLCK)) compared to the control. Whereas, the lowest collagenase activity was obtained at 20% AMLE compared to the control. These inhibitory effects further maintain the firmness of M. rosenbergii coated with 20% AMLE up to the eighth day of storage when compared to the control. Meanwhile, the highest penetration work was found in the M. rosenbergii coated with 20% AMLE at the twentieth day of storage. In conclusion, treatment at 20% AMLE could be used as a natural preservative to inhibit protease, trypsin and collagenase activity of M. rosenbergii and thus can maintain firmness for up to 8 days of storage.
