Effect of carbon dots with chitosan coating on microorganisms and storage quality of modified‐atmosphere‐packaged fresh‐cut cucumber

Abstract: BACKGROUND In order to inhibit microorganisms and improve storage quality of fresh‐cut cucumber, fresh‐cut cucumber was treated by carbon dots (CDs) from kelp/chitosan (CH) coating solution with CD concentrations of 0%, 1.5%, 3% and 4.5% and then packaged as well as stored at 4 °C for 15 days. The effect of CDs/CH coating on microorganisms and the quality of modified‐atmosphere‐packaged fresh‐cut cucumber during storage were investigated. RESULTS The CDs was monodispersed spherical morphology with size distrib… Show more

“…This can be explained by the slowing down of respiration rate (Tables 1 and 2) and senescence activities caused by low (0.5 ppm) ozone dose. Similarly, Fan et al (2019) reported that the decrease in SSC was due to the senescence of crops during storage. On the other hand, suppressing the respiration rate of horticultural crops delays the conversion of complex carbohydrates to simple sugars, which results in high SSC (Rohani et al, 1997).…”

“…The firmness of the sliced carrots was measured using a texture analyser (TA-XT2i, UK) according to the method of (Fan et al, 2019). The measurement was carried out at a pretest speed of 2.00 mm s -1 , and the test speed and posttest speed were determined at a penetration distance of 10 mm to determine the maximum force (N).…”

“…Low field nuclear magnetic resonance (LF-NMR) was used to analyse the transverse relaxation time (T 2 ) of carrot as presented by (Fan et al, 2019) using an analyser (MiceoMR20-030V-1, Numag Electric Co., Suzhou, China) with a resonance frequency of 23.2 MHz and a 0.5 T magnetic field intensity. The operating temperature of the magnet was 32°C.…”

“…Currently, C-dots represent a promising alternative to metal-based and colloidal nanoparticles for in vitro/ in vivo applications, including catalysis and energy fields, sensor and biosensors, electromagnetic interface shielding, bioimaging, gene transmission, drug delivery, and food production. 6,7 Some characteristics of C-dots, including high water solubility, biocompatibility, fluorescence properties, low/no toxicity and antimicrobial/antioxidant properties, make them valuable nanomaterials for further assessments and applications. Functional features (e.g.…”
