Control Efficacy of Salicylic Acid Microcapsules against Postharvest Blue Mold in Apple Fruit.

Salicylic acid (SA) is a natural inducer of disease resistance in fruit, but its application in the food industry is limited due to low water solubility. Here, SA was encapsulated in β-cyclodextrin (β-CD) via the host-guest inclusion complexation method, and the efficacy of SA microcapsules (SAM) against blue mold caused by in postharvest apple fruit was elucidated. It was observed that SAM was the most effective in inhibiting the mycelial growth of in vitro.

Hydroxyl-terminated carbon dots for efficient conversion of cyclohexane to adipic acid.

Adipic acid (HOOC(CH)COOH, AA) is a crucial chemical in industrial manufactures and mainly produced by the oxidation of cyclohexane with air and nitric acid via a homogeneous two step path in industry. However, the conventional industrial method inevitably results in the generation of nitrous oxide (NO, etc.), which is the main cause of the greenhouse effect and ozone depletion.

Preservation of traditional Chinese pork balls supplemented with essential oil microemulsion in a phase-change material package.

Background: In this study, we evaluated the combined effect of cinnamon essential oil (CEO) microemulsions, and a temperature buffering package using phase-change material (PCM) microcapsules on the physicochemical property, lipid oxidation, and bacterial load of traditional Chinese pork balls (shi zi tou) during temperature fluctuation storage for 9 days.

Results: Transmission electron microscope characterization revealed that n-tetradecane microcapsules possessed a core-shell spherical shape with a size ranging from 300 to 600 nm. The use of n-tetradecane microcapsule packaging was found to maintain cold storage temperature efficiently.
