Abstract
To prevent food losses, particularly those associated with financial losses, researchers are still working to determine the index for monitoring the freshness of green peppers during storage. This research aimed to examine the feasibility of using fluorescence spectroscopy to determine the freshness index. It was established the time series fluorescence properties were from various parts of green bell pepper (Capsicum annuum L.) during storage. For each evaluation, three measurements of the Emission and Excitation Matrix (EEM) fluorescence were carried out through the period of 16 days of storage at 4ºC. No difference was observed in color and chlorophyll content throughout the storage of green pepper. However, firmness was the destructive analyses more sustainable to determine freshness compared to the others, observing changes as of day 12 after harvest. The fluorescence emission peak at 450 nm on the excitation of 360 nm was observed to be potential as the freshness index showing the correlation with texture parameter showing R2 = 0.82. Therefore, this is a novel technique that should be further studied to optimize its use in the food industry to monitor fruits and vegetables during their preservation and to prevent food losses.
期刊介绍:
The journal is devoted exclusively to the publication of original papers, review articles and frontiers articles on biological and technological postharvest research. This includes the areas of postharvest storage, treatments and underpinning mechanisms, quality evaluation, packaging, handling and distribution of fresh horticultural crops including fruit, vegetables, flowers and nuts, but excluding grains, seeds and forages.
Papers reporting novel insights from fundamental and interdisciplinary research will be particularly encouraged. These disciplines include systems biology, bioinformatics, entomology, plant physiology, plant pathology, (bio)chemistry, engineering, modelling, and technologies for nondestructive testing.
Manuscripts on fresh food crops that will be further processed after postharvest storage, or on food processes beyond refrigeration, packaging and minimal processing will not be considered.
