“…For example, low temperature helps prevent the postharvest weight loss of fruits during storage 50 . By contrast, high temperature accelerates the postharvest weight loss of sugarcane cultivars during storage 51 . In this study, we found that different temperature treatments resulted in the postharvest weight loss of tea leaves.…”

Tea is an important non-alcoholic beverage worldwide. Tea quality is determined by numerous secondary metabolites in harvested tea leaves, including tea polyphenols, theanine, caffeine, and ascorbic acid (AsA). AsA metabolism in harvested tea leaves is affected by storage and transportation temperature. However, the molecular mechanisms underlying AsA metabolism in harvested tea leaves exposed to different storage and transportation temperature conditions remain unclear. Here we performed RP-HPLC to detect dynamic changes in AsA content in tea leaves subjected to high- (38 °C), low- (4 °C), or room-temperature (25 °C) treatments. The AsA distribution and levels in the treated tea leaves were analyzed using cytological–anatomical characterization methods. The differentially expressed CsAPX1 and CsDHAR2 proteins, which are involved in the AsA recycling pathway, were identified from the corresponding proteomic data using iTRAQ. We also analyzed the expression profiles of 18 genes involved in AsA metabolism, including CsAPX1 and CsDHAR2. AsA was mainly distributed in tea leaf mesophyll cells. High- and low-temperature treatments upregulated the CsAPX1 and CsDHAR2 proteins and induced CsAPX and CsDHAR2 gene expression. These results indicated that the CsAPX1 and CsDHAR2 proteins might have critical roles in AsA recycling in tea leaves. Our results provide a foundation for the in-depth investigation of AsA metabolism in tea leaves during storage and transportation, and they will promote better tea flavor in tea production.

“…b). The presence of AI and NI enzymes was strongly influenced by duration of storage (Verma et al ., ). SS activity decreased sharply in the first 2 weeks, followed by a slight increase, then declined rapidly in the eighth week, while almost no differences about its activity and change tendency were found in both treatments (Fig.…”

Vegetable soya bean deteriorates quickly after harvest at ambient temperature due to loss of green colour and consequent yellowing of grains. To seek an effective method to control the postharvest quality, the effect of exogenous spermine on visual quality, sugar loss and sucrose-metabolising enzyme activities of vegetable soya bean (Glycine max L.) during cold storage was investigated. The results showed that exogenous spermine (1.0 mmol L À1 ) noticeably prolonged shelf life, inhibited the increase of weight loss and decay index and retained the colour. It also significantly minimised sucrose loss by regulating the activities of sucrose-metabolising enzymes. Sucrose content negatively correlated with acid invertase (AI) activity at P < 0.05, while positively with sucrose phosphate synthase (SPS) activity at P < 0.01. There was no significant correlation with the activities of neutral invertase and sucrose synthase. These results indicated that the AI and SPS activities might play an important role in the control of sucrose metabolism resulting in reduction of sucrose loss.

“…The altered balance among the plant functions leads to many undesirable changes in the composition of the stalk. These adverse effects are worsened by the increased duration of the postharvest storage period between harvest and mill processing and high ambient temperatures (Verma et al, 2012). Due to respiration, an increase in temperature within the heap is likely to have signi cant consequences for the postharvest stalk rage and juice quality.…”

“…Only approximately 33% of the energy released in sucrose's oxidative catabolism is captured in ATP's chemical bonds (Siedow and Day, 2000). The remaining energy degenerates as heat that signi cantly contributes to the warming of the storage piles Verma et al, 2012).…”

Background Sugarcane is an essential crop for sugar and ethanol production. Immediate processing of sugarcane is necessary after harvesting because of rapid sucrose losses and deterioration of stalks. This study was conducted to fill the knowledge gap regarding the exploration of fungal communities in harvested deteriorating sugarcane. Experiments were performed on simulating production at 30 ℃ and 40 ℃ after 0, 12, and 60 hours (h) of sugarcane harvesting and powder-processing. Results Both pH and sugar content declined significantly within 12 h. Fungal taxa were unraveled using ITS amplicon sequencing. With the increasing temperature, the diversity of the fungal community decreased over time. The fungal community structure significantly changed within 12 h of bagasse storage. Before storing, the dominant genus (species) in bagasse was Wickerhamomyces (W. anomalus). Following storage, at 30 ℃ and 40°C, Kazachstania (K. humilis) and Saccharomyces (S. cerevisiae) gradually grew, becoming abundant fungi. We found that the bagasse at different temperatures had a similar pattern after storage for the same intervals, indicating that the temperature was the primary cause for the variation of core features. Moreover, the impact of dominant fungal species on sugar content and pH of stored sugarcane juice was investigated. Also, the correlation between top fungal genera and significant environmental factors was assessed. Conclusions The study highlighted the importance of timeliness to refine sugar as soon as possible after harvesting the sugarcane crop. The lessons learned from this research are vital for sugarcane growers and the sugar industry for minimizing postharvest losses.
