“…Flavan-3-ols, such as catechin and epicatechin, and oligomeric proanthocyanidins have inhibitory and antifungal properties toward different fungi including Botrytis cinerea . Thus, the observed efficacy of treatments with high CO 2 in table grapes to control decay caused in particular by B. cinerea could also be due to the enhanced synthesis of monomeric and oligomeric flavan-3-ols in the skin of CO 2 -treated berries. Considering that the potent nephrotoxin ochratoxin A, which is present in food and beverages including wine, is produced in harvested berries prior to the alcoholic fermentation and that high CO 2 was found to be effective in reducing the growth of different mycotoxigenic molds , it would be interesting to evaluate the effect of this treatment also in terms of the control of mycotoxin contamination in berries undergoing both limited or prolonged postharvest dehydration processes.…”

Detached wine grapes ( Vitis vinifera cv. 'Trebbiano', white skinned) were treated for 3 days with 30 kPa of CO(2) and then transferred to air for an additional 9 days to partially dehydrate (about 20% weight loss). At the end of the CO(2) treatment on withering berries, total polyphenols and flavonoids were maintained in the skin, but to a more limited extent in the pulp. An induction of the proanthocyanidin synthesis appeared to be one of the responses to the treatment because both (+)-catechin and (-)-epicatechin concentrations increased in the skin. The skin and pulp of the grape berries showed different molecular responses to a high CO(2) treatment. As revealed by microarray hybridizations, 217 and 75 genes appeared differentially expressed in the skin and pulp of treated samples, respectively. Functional categorization and gene enrichment analyses pointed out that epicarp cells undergo more pronounced changes in transcript profiling at the end of the incubation period. Highly represented categories in both tissues were related to protein, stress, transcript, RNA, and hormone (ethylene, ABA) metabolism. Fermentation, CHO metabolism, and redox regulation functional categories were represented only in the skin.

Berry antioxidants: small fruits providing large benefits

et al. 2013

Small berry fruits are consumed because of their attractive colour and special taste, and are considered one of the richest sources of natural antioxidants. Their consumption has been linked to the prevention of some chronic and degenerative diseases. The term 'berry fruits' encompasses the so-called 'soft fruits', primarily strawberry, currants, gooseberry, blackberry, raspberry, blueberry and cranberry. The objective of this review is to highlight the nutraceutical value of berries and to summarize the factors affecting berry fruit antioxidants. Particular attention is given to postharvest and processing operation factors that may affect fruit phytochemical content. The structure-antioxidant relationships for phenolic compounds - the main group of antioxidants in this fruit group - are presented and major areas for future research are identified.

“…Respiration is mostly affected by temperature and the respiratory gaseous environment (Wang et al, 2019). Hence, the combination of low temperature storage and controlled atmosphere (CA) technology has been used for many years to maintain physical and functional quality (Terry et al, 2009). For blueberries, a high concentration of carbon dioxide (CO 2 ) has a positive impact on decay suppression (Retamales and Hancock, 2018).…”

Blueberries (Vaccinium corymbosum L.) are highly valued for their health-promoting potential, yet they are extremely perishable. Controlled atmosphere (CA) strategies reduce blueberry respiratory metabolism, slowing down senescence. However, the sudden change of atmosphere could elicit a physical abiotic stress in the fruit, negatively affecting quality. We propose an innovative approach based on controlled graduation to slowly reach optimum gas storage conditions as an alternative to standard CA. For two consecutive seasons, "Duke" blueberries were subjected to four different storage conditions: control (air); standard CA (sudden exposure to 5 kPa O 2 and 10 kPa CO 2 across the experiment); GCA3 and GCA7 (gradually reaching 5 kPa O 2 and 10 kPa CO 2 in 3 and 7 days, respectively). Fruit were stored for 28 days at 0 ± 0.5 • C. Real-time respirometry provided an in-depth insight to the respiratory response of blueberries to their gas environment. Blueberries subjected to the graduated application of CA (GCA) treatments had a lower steady-state respiration rate compared to control and standard CA fruit. This indicated a reduction in metabolic activity that positively impacted quality and storage life extension. For example, GCA3 and GCA7 blueberries had a 25% longer storage life when compared to control, based on reduced decay incidence. In addition, GCA fruit were 27% firmer than control and CA fruit after 28 days of cold storage. GCA3 had a positive effect on maintaining individual sugars concentrations throughout the experiment, and both GCA treatments maintained ascorbic acid content close to initial values compared to a decrease of 44% in the control fruit at the end of the experiment. This work provides a paradigm shift in how CA could be applied and a better understanding of blueberry physiology and postharvest behavior.
