In this study, some selected physico-chemical properties (antioxidant activity, ascorbic acid, fatty acids, fruit colour, fruit juice yield, fruit weight, organic acids, pH, total phenolic and total soluble solid contents) of five black mulberry (Morus nigra L.) genotypes grown in the Northeast Anatolia region of Turkey was investigated. The total phenolic and antioxidant activity of methanol extract of black mulberry fruits were determined according to Folin-Ciocalteu and β-carotene bleaching method assays, respectively. Fatty acids of mulberry fruits were determined by using gas chromatography. Total phenolic content was observed in black mulberry fruits between 1943 and 2237 mg gallic acid equivalents/100 g fresh mass. The vitamin C content of genotypes varied between 14.9 and 18.7 mg/100 ml. The major fatty acids in all mulberry fruits were linoleic acid (53.57–64.41%) and palmitic acid (11.36–16.41%). Antioxidant activity of black mulberry genotypes was found between 63% and 76%, which lower than standard BHA and BHT. Regarding organic acid content, malic acid was the most predominant with a range of 123–218 mg/g followed by citric acid (21–41 mg/g). The results of the study are helpful for attempting crop improvement in black mulberry for bringing to cultivation. 相似文献

Persia is one of the main origin centers of pomegranate; hence, a diverse germplasm has evolved in the area over the past centuries. This study was conducted to evaluate the physico-chemical properties of fruits of ten Persian pomegranate cultivars. The plants used for this experiment had been collected from different parts of Iran and were established in a repository. Wide variations in the main properties of the ripe fruits of the cultivars were observed. The size, weight, skin thickness and weight, and juice content of the fruits were within the range of 55.14–71.76 mm, 98.55–199.40 g, 1.07–3.93 mm, 28.96–66.95 g, and 2.00–89.33 ml, respectively. Seed weight, Aril numbers, fresh and dry weight of 100 arils were 33.80–72.90 g, 170.70–570.30, 23.16–42.82 g, and 17.22–33.87%, respectively. The levels of total anthocyanin, total soluble solids (TSS), titrable acidity (TA), ascorbic acid, total phenolics, electrical conductivity, and TSS/TA ratio were ranged between 5.91–180.70 mg/100 g, 9.35–13.93 °Brix, 0.16–2.28%, 7.15–1061 mg/100 ml, 3578–5108 mg/100 g, 2.51–4.93 dS/m, and 4.09–80.34, respectively. The results emphasized on the role of plant genotype on fruit taste parameters, bioactive compounds, and yield. The variations in the fruits indicated differences in nutritive quality, which may satisfy diverse consumer acceptance in different areas. Moreover, it provides great opportunities for improving crop yield and quality. 相似文献

In this study, average weight, colour, soluble solids content and titratable acidity were determined as quality parameters of strawberry fruits while ascorbic acid, total anthocyanins, total phenolics, total flavonoids, minerals and trace elements content as nutritional parameters. All these attributes along with the DPPH radical scavenging activity were screened in two strawberry genotypes grown on the same site at the ripe stage. Also, the phenolic profiles of the strawberry fruits were obtained by HPLC. Except colour, results showed no significant differences between cultivars in quality parameters. Ascorbic acid found for ‘Premial’ cv. (81.62?mg/100?g) was twice the amount found in ‘Magic’ cv. (42.15?mg/100?g), total phenolics varied from 207.95 (cv. ‘Premial’) to 249.98 (cv. ‘Magic’) mg GAE/100?g while total flavonoid content in fruits of ‘Magic’ cultivar (79.56?mg/100?g) was 2?fold higher than the one of the ‘Premial’ cv. The quercetin content ranged from 2.72 to 4.66?mg/100?g, whereas free ellagic acid ranged from 6.79 to 9.03?mg/100?g. The pale shiny fruits of ‘Premial’ cv. (higher L*, ho and chroma index) had a lower total anthocyanin content (19.07?mg CG/100?g) than the bluish fruits of the ‘Magic’ cv. (23.96?mg CG/100?g). An inverse relationship between the levels of ascorbic acid and anthocyanin contents was also noticed in strawberry samples. Significant differences were found also in minerals and trace elements content of the two strawberry cultivars. The results revealed the importance of genetic background for the content of antioxidant compounds in strawberry fruits. 相似文献

Turkey is an important gene centre of rosehip populations and rosehip is naturally grown in the province of Ad?yaman. This study has been conducted on rosehip fruits found in various altitudes in Ad?yaman to determine the changes of their physico-chemical characteristics. The fruit weights of the genotypes used in the study ranged between 2.72?g–1.29?g, fruit width between 14.12–10.44?g and fruit length has ranged between 23.18?mm–18.62?mm. The rosehip genotypes to be processed to food are required to have a bulky fruit and a high amount of fruit flesh. The genotype with the highest fruit flesh ratio was found to have the lowest seed weight by 0.25?g, while the genotypes with the highest seed weight had this value ranging between 0.50–0.59?g. Rosehip genotypes dry matter ratio has ranged between 44.27 and 37.11%. While the a*, b*, C* and h° values of rosehip fruits had significant differences based on the genotypes, L* values had similarities. Genotypes had ranging WSDM contents of 33.56–22.50%, TA contents of 2.96–1.57%, pH values of 4.06–3.82, C vitamins of 782.34–352.16?mg/100?g, total phenol contents of 5.42–3.62?mg GAE/g DM and antioxidant activities of 113.60–56.80?µmol TE/g DM. The rosehip fruits containing high levels of fructose and glucose were found to be low in saccharose content. Fructose, glucose and saccharose contents of rosehip genotype fruits were found to be 22.93–16.86, 20.22–13.77 and 0–0.90?g/100?g DM, respectively. According to the outcomes of the study, physico-chemical characteristics of the rosehip fruits displayed significant differences, and these differences were affected by type, genotype and ecologic conditions. 相似文献
