Turkish Journal of Agriculture and Forestry
In this study, the effects of 1-methylcyclopropene (1-MCP) treatment on the antioxidant enzymes and fruit quality parameters of baby squash (Cucurbita pepo L., cv. Soleil F1 and İskender F1) during cold storage was investigated. After being freshly harvested, the İskender F1 (green-skinned) and Soleil F1 (yellow-skinned) baby squash were treated with 250 and 500 ppb concentrations of 1-MCP and stored at 10 °C for 14 days. The 250 ppb 1-MCP treatment suppressed the loss of total soluble solid, ascorbic acid, total phenolic, and total flavonoid contents during storage in the Soleil F1 squash. Similarly, the 250 ppb 1-MCP treatment delayed …

Turkish Journal of Agriculture and Forestry
In this study, the effects of cooking and the addition of extra virgin olive oil on the in vitro bioaccessibility of carotenoids in tomato sauce were evaluated. The results indicated that total antioxidant activity, α-tocopherol, lycopene, β-carotene, lutein, and chlorophyll a contents were positively affected by the combination of cooking and addition of extra virgin olive oil. Moreover, after in vitro digestion, for intestinal phase, lycopene and Β-carotene were observed in all samples, whereas α-tocopherol and chlorophyll a were not detected in any of the samples. Lycopene (≈8.5-fold) and β -carotene (≈5-fold) were significantly improved (P < 0.05) by the effect of cooking and addition of extra virgin olive oil to the samples compared to control tomato sauce (without oil and cooking).

Ten different Persian walnut cultivars were examined for their compositional data, including eight Hungarian and two introduced varieties. Oil content and fatty acid composition were determined, as well as oxidative stability (indicated by induction time). Antioxidative capacity, total polyphenol measurements, and individual phenolic compounds were also determined. Not only dry samples but fresh and stored samples were included in this study. Large differences were found among the varieties within these parameters, for example in oxidative stability, which contributes to antioxidative capacity. In conclusion, the nutritional value of Hungarian walnut cultivars was the same or even higher than those of foreign …

Biochemical And Sensory Evaluations Of Turkish Delight (Lokum) Enriched With Black Grape And Sour Cherry Syrups, Ali̇ Batu, Ali̇ Arslan
Turkish Journal of Agriculture and Forestry
Black grape and sour cherry are high in phenolic substances and anthocyanin compounds, which are important for human health. Adding black grape and sour cherry fruit syrups into Turkish delight (lokum) could make the product healthier. While the highest antioxidant activity (AA) was found in the products produced with 7.5% black grape syrup (BGS) and sour cherry fruit syrup (SCS), the lowest AA was obtained from the control sample. The AA values of Turkish delight produced with BGS and SCS increased with the increased fruit concentration. Turkish delight produced with SCS had about twice as much AA than that produced …

Dairy and meat production are very complex in dry regions due to shortages and the low quality of fodder, especially in dry months. Livestock scientists are enthusiastic to explore and investigate good quality fodder that can boost milk and meat production in an economical way. Moringa oleifera is known as one of the best fodder crops for dry regions with scanty amounts of water. Hence, the present study was designed to evaluate the potential of Moringa oleifera as a field crop by harvesting at different cutting heights (30, 90, and 150 cm). The nutritional quality (minerals like P, K, Ca, …

Tomato is one of the most widely produced and consumed vegetable crops worldwide. Plant breeders have usually focused on improvement of horticulturally important traits such as yield, fruit size, shape and colour. With increased attention on human health, however, plant breeders also consider the improvement of health-related traits of fruits and vegetables such as antioxidant characters. In the present study, genes controlling both health-related and horticulturally important traits were mapped in the tomato genome using 152 Lycopersicon hirsutum BC_2F_2 individuals. For this aim, all plants were phenotypically and genotypically characterised and a total of 75 QTLs were identified for all …
