- Abstract:
- ... Sucrose acts as a vital signal that modulates fruit ripening. In current study, 50 mM sucrose was applied in strawberry fruit to investigate the regulation of sucrose in anthocyanin synthesis after harvest. The results showed that sucrose treatment increased the contents of glucose, fructose and sucrose, which were 19.76%, 15.83% and 16.50% higher, respectively, compared with control at the end of ...

- Abstract:
- ... Lignification is a typical characteristic of senescence of bamboo shoots during postharvest storage. In this study, exogenous hydrogen peroxide (H2O2) and diphenyliodonium iodide (DPI) were applied to postharvest bamboo shoots to explore the regulation of H2O2 in the lignification process. Bamboo shoots, soaked in 10 mM H2O2 or 5 mM DPI for 10 min, were stored at 20 ± 1 °C for 12 d. H2O2 treatment ...

- Abstract:
- ... As an environmentally friendly approach for fruit quality improvement, the effect of preharvest UV-C on the physiology of strawberry fruit during postharvest storage remains to be assessed. Strawberry fruit developed with supplementary UV-C were stored at room temperature for 2 weeks. Preharvest UV-C attenuated fruit postharvest senescence and altered phytochemicals composition. Higher ester titer ...

- Abstract:
- ... Colour is an important quality attribute for the consumer’s acceptability of fruit. Elevated CO2 was applied to strawberry fruit to explore its influence on chlorophyll catabolism and anthocyanin synthesis. The results showed that 20% CO2 delayed the changes of a* and b* values in strawberry fruit. The degradation of chlorophyll was delayed in CO2 treated fruit by inhibiting the activities of chlo ...

- Abstract:
- ... Ultraviolet‐C (UV‐C) radiation has been reported to induce defence responses to pathogens in growing crops and described as a new environmentally friendly method for disease control. However, whether the effect of the induced defence mechanisms will persist after the stress imposed by UV‐C is alleviated and how these mechanisms interact with pathogen elicitors upon infection have not yet been inve ...

- Abstract:
- ... Although farming and consuming of soft‐shelled turtle has been practised for centuries, the aroma‐impact compounds in the meat have not been determined. Furthermore, matrix pH, usually changing during processing and storage stage, was rarely investigated for the influence on volatile profiles. To these aims, soft‐shelled turtle meat was subjected to different pH conditions and the potential volati ...
