Solar tunnel drying and semiwash processing methods are popular among coffee growers in southwestern Ethiopia. However, the effect of these on quality has not been studied detail. The objective this study was to evaluate varieties at Gomma-I Limmu Kossa areas 2016/2017 growing season. Two (fully washed semiwashed) three (solar tunnel, artificial, natural sun) were compared using (741, 7440, 741...

Since ancient times, conventional techniques of food drying, such as sun have been used. Currently, drying methods developed with the latest technology to reduce damages caused by biochemical changes, which decrease nutritional value during process. Some typical used for products are solar tunnel dryer, cabinet-type etc. While this is going on, cutting-edge being created combine several produce...

This paper covers the post-harvest aspects, processing and quality assurance for speciality/organic coffee products. It starts with the origins of coffee, what aspects provide inherent quality, and diseases that deter quality. It then touches on coffee harvesting, the timing for harvesting and development of fruit color. It discusses picking systems, both manual and mechanical and their effects...

The study investigated the functional properties of HQYF (high-quality yam flour) from tubers of four dioscorea species. The tubers were processed into HQYF using two pretreatments (potassium metabisulphite: 0.28%, 15 min; blanching: 70°C, 15 min) and drying methods (cabinet: 60°C, 48 h; sun drying: 3 days). Significant differences (P < 0.05) were observed in pasting characteristics of flours a...

This study was conducted to evaluate the effects of different levels of osmotic pretreatments prior to drying and different drying methods on nutritional quality of dried mushroom slices. The experiment consisted of sun, solar, and oven drying after dipping the slices in salt solutions of 5 and 10% concentrations for 50 minutes, the control being untreated mushroom sample. Significant differenc...

The pomegranate (Punica granatum L.) is an important medicinal plant. It has been reported that phenolic compounds contained in the flowers have antioxidant potential. The objective was to determine the concentration of total phenolics and antioxidant capacity of three selections of pomegranate flower dried under different conditions. The highest phenolic content and antioxidant capacity was ob...

Kurozu (or Kurosu) is traditional Japanese black vinegar made by prolonged fermentation of unpolished rice that contains rice germ and rice bran [1]. While there are several preparation methods, one native to Kagoshima prefecture involves drying the fermented product in the sun for more than a year in earthenware jars. The liquid concentrate after drying is called Kurozu and the sediment at the...

Abstract Researchers have carried out the kinetics of various agro products for open sun drying, but research articles still need to address such analysis cotton seeds. Open drying seeds has been experimentally investigated and presented in this paper. Shorting was collect appropriate samples current work. Cotton were found a nearly ovoid shape with an average radius 2 2.5 mm. The initial moist...

In this study, coriander leaves were subjected to three different drying techniques; direct sun, shade, and using an indirect solar dryer. the developed dryer, hot air obtained from a black-body collector was pushed by blower powered panel, sent chamber with multiple trays for thin-layer drying. Experiments conducted summer winter seasons, temperature relative humidity variations in measured da...

The content of 12 elements in Cambodian dried striped snakehead fish was determined using inductively coupled plasma mass spectrometry. The present study compares the level of the trace toxic metals and nutritional trace elements in the fish processed using solar drying system (SDS) and open sun drying (OSD). The skin of SDS fish has lower level of As, Pb, and Cd compared to the OSD sample. As ...
