Preparation of bioactive film for regulating chlorine dioxide release based on the hygroscopic properties of chitosan and its application in broccoli preservation.

An active packaging film was developed by integrating sodium chlorite (SC) and citric acid (CA) into a Poly(lactic acid)/Poly(butylene adipate-co-terephthalate) (PLA/PBAT) matrix, enabling the controlled release of chlorine dioxide (ClO) gas. The release of ClO was further regulated by introducing chitosan (CS) into the film, leveraging its hygroscopic properties. The results showed that when the addition amount of CS was 4 wt%, the water vapor transmission rate increased by 41.

Synthesis, magnetic and NMR spectroscopic properties of the MAlPt series (M = Ca, Y, La-Nd, Sm-Er).

Following recent investigation in the ternary system Sr-Al-Pt led to the discovery of SrAlPt which crystallizes in the orthorhombic YNiSi type () structure. Interestingly, only two more aluminum representatives, CeAlPt and EuAlPt, have been reported to adopt this structure type. Therefore, we decided to investigate the existence range of compounds adopting the YNiSi type structure.

Relationship between wooden breast severity in broiler chicken, antioxidant enzyme activity and markers of energy metabolism.

This study aims to provide new insight on the association between the development of wooden breast myopathy and mitochondrial and glycolytic activity under oxidative stress. Myopathic muscle had higher oxidative stress together with altered glycolytic metabolism and tricarboxylic acid (TCA) cycle. This was evidenced by significantly elevated antioxidant enzyme activities (catalase, superoxide dismutase, and glutathione peroxidase), decreased citrate synthase activity and postmortem glycolytic potential with increasing wooden breast severity.

Study on the Changes of Bone Calcium during the Fermentation of Bone Powders with Different Fermenters.

Two fermenters, (LA) and the active dry yellow wine yeast (HY), were utilized to ferment cattle bones in order to release calcium. The influences of fermenters and the fermentation process on the calcium release capacity, particle properties, morphology, and chemical composition of bone powders were assessed, and the underlying mechanism was discussed. The results showed that LA had a better capacity of acid production than yeast, and therefore released more calcium during the fermentation of bone powders.
