“…Overall, there was considerable (P < 0.001) variability due to the main effects (year, harvest date, genotype, and storage time) and their interactions on the TAC content of strawberry fruit. Several studies have previously shown that anthocyanin content varies significantly with the year, harvest date and genotype (Fredericks et al, 2012;Pozo-Insfran et al, 2006;Singh et al, 2011;Tulipani et al, 2011). The annual climactic changes during the season may result in different TAC accumulation patterns whereas specific genotype characteristic (e.g., surface color) are highly correlated with the TAC content of strawberries (Nunes, 2015).…”

Strawberries are one of the most important food crops grown in Florida, with a harvested area of ≈10,000 acres. The University of Florida strawberry breeding program develops cultivars adapted to this region and its particular weather conditions, with a major aim of increasing overall quality. The objective of this study was to compare the fruit of advanced breeding selections to those of commercial cultivars, for compositional attributes. Seven different strawberry genotypes were compared at harvest and after 7 days at 4 °C across multiple harvest dates during two consecutive years. Compositional attributes were highly influenced by year, harvest date within a year, genotype, and storage. Overall, compared with other genotypes, selection FL 09-127 exhibited consistently higher soluble solids and total sugar (TS) contents at harvest and after cold storage. Higher ascorbic acid (AA) and phenolic contents at harvest were observed in selection FL 07-193. However, its anthocyanin content was among the lowest. In contrast, FL 10-47 exhibited relatively low AA content at harvest but consistently high total anthocyanins (TACs) and total phenolic (TP) contents after storage. Overall, results from this study provide valuable information to the breeding process by identifying new genotypes with improved compositional attributes combined with suitable quality characteristics after cold storage.

“…Anthocyanin content in strawberry fruit is highly correlated with the color of the fruit. Thus, color has been considered a good screening tool for high anthocyanin strawberries in breeding programs (Fredericks et al, 2012;Nunes, 2015), though the dark color is often undesirable in commerce due to the perception that dark fruit are overripe.…”

“…Anthocyanins do not just improve tolerance to grey mould but also provide health benefits (Terry et al , ). Breeding for higher anthocyanin content in strawberries is possible and facilitated by existing variation in the germplasm (Fredericks et al , ; Jing, ). Inducing anthocyanin accumulation in flowers could also help to limit flower infections.…”

Summary The fungal pathogen Botrytis cinerea causes grey mould, a commercially damaging disease of strawberry. This pathogen affects fruit in the field, storage, transport and market. The presence of grey mould is the most common reason for fruit rejection by growers, shippers and consumers, leading to significant economic losses. Here, we review the biology and epidemiology of the pathogen, mechanisms of infection and the genetics of host plant resistance. The development of grey mould is affected by environmental and genetic factors; however, little is known about how B. cinerea and strawberry interact at the molecular level. Despite intensive efforts, breeding strawberry for resistance to grey mould has not been successful, and the mechanisms underlying tolerance to B. cinerea are poorly understood and under‐investigated. Current control strategies against grey mould include pre‐ and postharvest fungicides, yet they are generally ineffective and expensive. In this review, we examine available research on horticultural management, chemical and biological control of the pathogen in the field and postharvest storage, and discuss their relevance for integrative disease management. Additionally, we identify and propose approaches for increasing resistance to B. cinerea in strawberry by tapping into natural genetic variation and manipulating host factors via genetic engineering and genome editing.

“…It is also common to find applications in which the sample is re-extracted several consecutive times, in order to fully extract the target compounds. This strategy was shown to be useful to extract anthocyanins from strawberry [95], sweet potato [102] and grape skins [112], phenolic acids from food industry byproducts [96], flavonoids from spinach [118] or alkaloids [128], among others, performing 3 consecutive static extraction cycles.…”

ABSTRACT.The improvement of sample preparation and extraction techniques for natural bioactive compounds determinations is of great importance nowadays. New concepts are being introduced in this field, not only related to enhancement of extraction efficiencies but also related to environmental impact. This evolution towards Green Chemistry is pushing to new extraction and sample preparation processes that should be faster, more reproducible and more environmentally friendly. In this context, compressed fluidsbased sample preparation techniques (such as supercritical fluid extraction and pressurized liquid extraction) are demonstrating good capabilities. In this review, an updated knowledge on the techniques will be presented together with the main technical developments and the most notable recent applications for the extraction of bioactive compounds.Keywords: bioactive compounds, natural samples, plants, agricultural by-products, pressurized liquid extraction, supercritical fluid extraction, subcritical water extraction Abbreviations: ASE, accelerated solvent extraction; DHA, docosahexaenoic acid; EAE, enzyme-assisted extraction; EPA, eicosapentaenoic acid; IL, ionic liquids; MIP, molecular imprinted polymers; PFE, pressurized fluid extraction; PHSE, pressurized hot solvent extraction; PHWE, pressurized hot water extraction; PLE, pressurized liquid extraction; PLPW, pressurized low polarity water extraction; n-3 PUFA, n-3 polyunsaturated fatty acid; RAM, restricted access media; scCO2, supercritical CO2; SFE, supercritical fluid extraction; SHWE, superheated water extraction; SPE, solid Published in TrAC.
