The composition of fruit of different strawberry varieties depending on maturity stage
Food Chemistry, 2003
The fruits of the cultivars ‘Eros’, ‘Selena’, ‘Northaester’, ‘Fern’, ‘Simphony’, ‘Mohawk’, ‘Elsanta’, ‘Miss’, ‘Evita’, ‘Marmolada’, ‘Pegasus’, ‘Kent’ and ‘Cortina’ were chemicaly analysed. With the high-performance liquid chromatography (HPLC) method the individual sugars (sucrose, glucose, fructose and xylose) and organic acids (citric, fumaric and shikimic) were estimated in two different stages of ripeness: the stage of technological ripeness and the stage of complete ripeness. Statistical differences among the fruits of the same cultivar and of different maturity stages were established in the contents of glucose, fructose, xylose, fumaric and shikimic acids, but there were no statistical differences in the contents of sucrose and citric acid. Among the fruits in the stage of complete ripeness the cvs. ‘Mohawk’ and ‘Evita’ were outranking with regard to the content of sucrose, while the fruits of the cvs. ‘Fern’ and ‘Northaester’ attained the highest contents of glucose, fructose and citric acid. During the same time of ripeness the highest content of total soluble solids (TSS) was measured in the cv. ‘Mohawk’, and the lowest content of TSS was exhibited by the cv. ‘Miss’. The results of the analyses conducted during the research confirm that the chemical composition of strawberry fruits significantly varied among the genotype of the plant and on the stage of maturity of fruits. Therefore harvesting in optimal fruit bearing time is essential for achieving good quality of strawberries, since important changes in the content of individual sugars and acids occur in the last period of maturity as well.
Article Variation in the Bioactive Compound Content at Three Ripening Stages of Strawberry Fruit
2014
During the harvest season of two consecutive years, five strawberry cultivars ('Arosa', 'Elsanta', 'Marmolada', 'Miss' and 'Raurica'), grown in the continental part of the Republic of Croatia, were examined. Strawberry fruits quality was evaluated by individual phenol compounds, individual anthocyanins and fruit color. Fruits were harvested in three different periods. Analyzed strawberry cultivars show very good average values of the studied phenolic acids and flavonoids with predominant caffeic acid and epicatechin content in all researched strawberry cultivars. Considering the content of individual anthocyanins, pelargonidin 3-glucoside is predominant in strawberry extract followed by cyanidin-3-glucoside and pelargonidin 3-rutinoside. The correlation between individual anthocyanin content and chromaticity parameters was detected in all strawberry cultivars, additionally correlation coefficients and statistical significance were much lower. The results show a positive association between cultivar and harvest time on strawberry pulp color, with each of the color variables, a, b, a/b ratio, C, L and h° values.

Fruit Quality Evaluation of Strawberry Cultivars Grown in Argentina
Fruit quality of different strawberry (Fragaria x ananassa) cultivars was evaluated in Tucuman (Argentina) from June to August (2001), a period when fruit prices are above the average values of the season. Cold-stored (frigo) plants (FGP) of 'Aromas', 'Camarosa', 'Gaviota' and 'Selva', and fresh plants (FHP) of 'Camarosa', 'Earlibrite', 'Gaviota', 'Rosa Linda', 'Sweet Charlie' and 'Tud New' were grown in a winter production system. Fruit were harvested periodically and samples of 15 fruit (>75% red color) per cultivar were analyzed during June and July (FGP) and August (FHP). Fruit quality was evaluated in terms of fruit weight, external and juice color (L*, °hue, chroma), firmness, soluble solids (SSC) and ascorbic acid contents, acidity and ratio (SSC/acidity). Within FGP, 'Camarosa' and 'Selva' had the highest external chroma values, while 'Gaviota' and 'Aromas' had intermediate and the lowest external chroma values, respectively. Levels of acidity were different within cultivars, with 'Camarosa' being the most acid of the group. Within FHP, 'Tud New' had high fruit weight, firmness, ascorbic acid content, and low °hue, which is desirable in terms of quality; however, L* (external and juice), SSC and ratio were low. ‘Camarosa’ had relatively high values of firmness, SSC and acidity, and was low in external and juice °hue. 'Earlibrite' had relatively high values of fruit weight, firmness, SSC, acidity and ascorbic acid. 'Sweet Charlie' had high SSC, intermediate firmness, and low acidity and ratio. Although production patterns of FGP and FHP were not the same and both groups were not fruiting simultaneously, 'Camarosa' and 'Gaviota', which were included in both groups, produced smaller fruit from FGP than from FHP, but firmness and SSC in FGP were the highest. These differences could be related to the particular background of each kind of plant and/or to environmental conditions during the fruiting season.

Th e aim of this research was to determine diff erences in physical and chemical composition of strawberry fruits cv. Elsanta, grown in three diff erent cultivation systems, open fi eld, high tunnel and soilless culture. Experiment was conducted in Zagreb area. Fruits were harvested at the same time in all three cultivation systems, aft er which physical and chemical parameters were determined. Obtained data showed that fruits grown in open fi eld had the lowest fruit mass (17.0 g) compared to the ones grown in high tunnel (20.0 g) and soilless (21.0 g), however fruits grown in fi eld had the highest fruit fi rmness (0.76 kg cm -2 ). Values obtained by color analysis for light (L) ranged from 37.52 for fruits in soilless cultivation to 41.94 for fruits grown in open fi eld. Intensity (C) ranged from 24.71 in soilless to 31.65 in open fi eld and values obtained for angle of coloring (H) ranged from 47.44 in high tunnel to 54.77 in soilless culture.
The Influence Of Cultivation System On Biochemical Content Of Strawberry Fruits
Journal of Horticultural Research, 2014
Three cultivars 'Zefyr', 'Honoeoye' and 'Polka' were grown on beds mulched with black plastic or without it, as well as in low tunnels covered by transparent polyethylene film or Agronet (Pegas agro, 17 g·m -2 ), or without covering. The quality of fruits determined by content of ascorbic acid, titratable acidity, soluble solids, total content of phenolics and anthocyanins, antiradical activity, and radical scavenging activity (RSA) was evaluated during two seasons. Significant differences in phytochemical contents within strawberry cultivars, production seasons and cultivation methods were stated. Cultivar had the greatest influence on the content of ascorbic acid, total phenolics and RSA among all the studied factors. The amount of anthocyanins was mainly influenced by plant covering, while the annual climatic conditions had the greatest impact on the amount of titratable acidity and soluble solids. Soil mulching had the lowest influence on the chemical content of fruits.

BACKGROUND: Strawberries are widely consumed in the world and an important source of health-promoting compounds, such as polyphenols. The nutritional quality as well as the phytochemical composition of strawberry fruits are known to be strongly influenced by genetic, environmental factors, ripeness at harvest, and storage conditions. OBJECTIVE: The nutritional quality and the phytochemical content of two new strawberry cultivars, namely 'Fuentepina' and 'Amiga', were evaluated. These novel cultivars were compared with 'Camarosa' and 'Candonga', the two most extended cultivars in Spain, and with 'Primoris', an emerging one. METHODS: The influence of genotype, stage of ripening and season on different properties as colour, firmness, acidity, soluble solids content, antioxidant capacity, and polyphenols profile were evaluated. RESULTS: Results showed significant effects of genotype, stage of ripening and season on the majority of the measured parameters. Thirty nine phenolic compounds were tentatively identified. Anthocyanins were the most abundant class of polyphenols in 'Amiga', 'Candonga', 'Camarosa' and 'Primoris' cultivars while more flavan-3-ols were recorded in 'Fuentepina'. CONCLUSIONS: 'Fuentepina' strawberries stand out for their pleasant flavour as a result of a high sugar/acid ratio and 'Amiga' strawberries may offer potential as a new promising cultivar due to its high firmness, good sugar/acid ratio and high content of phytochemicals.

Fruit Quality of New Early Ripening Strawberry Cultivars in Croatia
In this research fruit quality of seven early ripening strawberry cultivars (Clerry, Maya, Alba, Miss, Camarosa, Queen Elisa and Elsanta) during successive harvesting periods has been investigated. The following quality parameters were determined in the harvested fruits: dry matter, total soluble solids (TSS), pH, total acidity (TA), TSS/TA ratio, reducing sugars, sucrose, vitamin C, total anthocyanins, total phenolics (TP), nonflavonoids, flavonoids, antioxidant activity, and colour. Investigated cultivars differ significantly according to the basic chemical composition. The highest, statistically significant values of dry matter, soluble solids, TSS/TA ratio, vitamin C, total phenolics, nonflavonoids and antioxidant activity were determined for cultivar Elsanta. Among the other early ripening cultivars involved in the research, Alba and Maya had the lowest contents of dry matter, total soluble solids, total phenolics and nonflavonoids, reducing sugars and sucrose. The anthocyanin content was the highest in cultivars Camarosa, Miss and Maya; consequently, the most intensive colour was noted in the same cultivars. Parameters that determine fruit quality had lower values in all the investigated early ripening cultivars than in cultivar Elsanta; however, their quality was satisfactory.
