“…During the senescence period, the concentration of organic acids tends to decrease, due to the possible leakage of cell fluid and volatilization of these acids (Berli et al, 2004). This effect, however, was not observed in lamb's-ear leaves in the present study.…”

The objective of this study was to evaluate the influence of the packaging system on the useful life and post-harvest quality of lamb’s-ear leaves (Stachys byzantina L.). The sanitized sheets were packaged in four different packaging systems: (A) rigid polyethylene (PET), (B) PET together with ethylene-absorbing sachet, (C) PET wrapped with high barrier plastic film, and (D) PET together with an ethylene-absorbing sachet and wrapped with high barrier plastic film and stored at 7 ° C. Samples for physical-chemical analysis, bioactive compounds and antioxidant activity were removed before storing and at 5, 10 and 15 days of storage. The leaves contained in packages C showed less loss of mass and in system D they showed greater preservation of color attributes (L *, C * and °H). The packaging did not influence the contents of bioactive compounds, which showed higher values at 5 days of storage. The leaves stored in A, B, C and D showed high antioxidant capacity until the 15th day of storage. It was concluded that the quality atrib\utes of the lamb’s-ear leaves were kept in all packaging systems throughout 15 days of cold storage. The contents of bioactive compounds and antioxidant activity showed the highest values up to 5 days of storage at 7 ºC. Thus, considering the economic aspects and practicality in handling, packaging A is the most suitable for refrigerated storage (7 ºC) and commercialization of fresh lamb’s-ear leaves up to 15 days of storage.

“…NaDCC is widely used as a safe disinfection tablet in daily life and industries. Previous research indicated that application of NaDCC at 50 ppm can prolong shelf life of fresh-cut onion with higher pH value and lower titratable acidity [22]. Additionally, NaDCC treatment in combination with gamma irradiation is able to control soft rot disease caused by Rhizopus of sweet potatoes, pears and paprikas after harvest [23–25].…”

Sodium dichloroisocyanurate delays ripening and senescence of banana fruit during storage

Banana as a typical climacteric fruit soften rapidly, resulting in a very short shelf life after harvest. Sodium dichloroisocyanurate (NaDCC) is reported to be an effectively antibacterial compound. Here, we investigated the effects of NaDCC on ripening and senescence of harvested banana fruit at physiological and molecular levels. Application of 200 mg L−1 NaDCC solution effectively inhibited the ripening and senescence of banana fruit after harvest. NaDCC treatment reduced greatly ethylene production rate and expressions of genes encoding 1-aminocyclopropane-1-carboxylate synthetase, 1-aminocyclopropane-1-carboxylate oxidase, ethylene-responsive transcription factor and EIN3-binding F-box protein. Meanwhile, NaDCC treatment down-regulated markedly the expressions of xyloglucan endotransglucosylase/hydrolase and pectinesterase genes. Furthermore, NaDCC treatment affected significantly the accumulation of ripening-related primary metabolites such as sugars and organic acids. Additionally, NaDCC treatment decreased the production of hydroxyl radical and increased 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging activity, reducing power and hydroxyl radical scavenging activity. In conclusion, NaDCC delayed effectively the ripening and senescence of harvested banana fruit via the reduced ethylene effect and enhanced antioxidant activity.Electronic supplementary materialThe online version of this article (10.1186/s13065-018-0503-5) contains supplementary material, which is available to authorized users.

“…Soluble solids represent the concentration of substances dissolved in the cellular content, including vitamins, pectins, phenols, organic acids, pigments, and sugars (Beckles, 2012). Still, according to Beerli et al (2004), the reduction in the soluble solids during storage probably occurs due to the consumption of substrates in the respiratory metabolism, characteristic of catabolic reactions of senescence. °Brix reduction during the storage of onion bulbs corroborates the studies carried out by Melo et al (2012), where, studying the cultivars Beta Cristal and Óptima during 60 days of storage, describe that the levels of soluble solids decreased differently between cultivars during the days of cold storage at 5 °C.…”

Post-harvest quality of onion bulbs in a controlled environment

The onion bulbs' post-harvest quality is essential for good commercialization; the longest storage time is critical to the producer in choosing the cultivar. Thus, this work aimed to evaluate the post-harvest quality of onion bulbs under storage periods in a controlled environment. The experiment was installed in a factorial scheme (6x4), represented by six onion cultivars (BR29, Itajubá, Mulata, Omega, Rainha, and Salto Grande), evaluated in four storage periods (40, 80, 120, and 160 days), in a randomized design, with three replications. The parameters of fresh matter loss, skin strength, bulb firmness, skin shine, pH, soluble solids, titratable acidity, and soluble solids and titratable acidity were analyzed. The cultivar Salto Grande presented better conservation of the physical-defined characteristics in the post-harvest at controlled temperature, less loss of mass of fresh matter, and more significant maintenance of the feature of skin strength, bulb firmness, soluble solids, and titratable acidity. At the same time, cultivar BR29 showed more significant losses in the studied attributes and had less storage capacity among the evaluated cultivars.
