Quality Characteristics Of Trabzon Persimmon Dried At Several Temperatures And Pretreated By Different Methods, Si̇bel Bölek, Ersel Obuz
Turkish Journal of Agriculture and Forestry
Although Trabzon persimmon (Diospyros kaki L.) is a beneficial fruit for both human health and industrial use, it is generally used seasonally, and inadequate attention has been given to its off-season use. This study was designed to determine the best drying method for optimizing the quality of dried Trabzon persimmon (Diospyros kaki 'Fuyu'). Samples treated with sodium metabisulfite prior to drying and dried at 65 °C had the highest L* value (P < 0.05). Rehydration value and ascorbic acid content of samples dried at 50 °C were the highest. Nevertheless, these samples had lower total phenolic content than samples dried at 65 °C and 90 °C. Samples treated with sodium metabisulfite before drying had the highest appearance score; however, these samples were the least liked and had the lowest flavor score. Control samples were the most popular samples in terms of flavor (P < 0.05). During storage, control group samples had the highest increase in total mesophilic aerobic bacteria, while samples treated with sodium metabisulfite prior to drying had the lowest increase in total mesophilic aerobic bacteria, owing largely to the antimicrobial effect of sodium metabisulfite. Although sodium metabisulfite treatment gave the best physical, chemical, and microbiological results, these dried persimmons were given the lowest sensory scores.

Long-Term Water Balance Of A Bare Soil With Slope In Chuncheon, South Korea, Mehmet Aydin, Yeong-Sang Jung, Jae E. Yang, Hyun-Il Lee
Turkish Journal of Agriculture and Forestry
Water balance components of a bare soil with slope varying from 5% to 30% in Chuncheon, South Korea, were simulated using the E-DiGOR model, which proposed an interactive way to quantify runoff, drainage, soil water storage, and evaporation. Daily computations were carried out during the period of 1980 to 2009 for the identified soil-topography-climate combination. A strong correlation between measured pan evaporation and calculated potential soil evaporation was observed (R^2 = 63.8%, P < 0.01) based on the monthly data of the past 30 years (hereafter 'long-term'). When examining long-term dynamics of simulated soil evaporation, monthly mean potential and actual soil evaporations ranged from 9.1 and 9.0 mm in December to 110.5 and 75.2 mm in June and July, respectively. The ratio of actual to potential soil evaporation (E_a/E_p) had a close linkage with soil water content. The higher the soil water amount, the greater the E_a/E_p ratio was. A nonlinear relationship between rainfall and surface runoff was obtained at a given slope. Excess surface runoff and subsurface flow (percolation + interflow) occurred throughout the rainy months from July to September, with peaks in July. The ratio of direct surface runoff to rainfall increased with the natural logarithm of slope. The long-term mean annual direct surface runoff and subsurface flow at the maximum slope were 408.1 and 437.6 mm, respectively. Furthermore, mean annual surface runoff from the slope of 30% was approximately 2 times higher than that from the slope of 5%.
