This study aims to evaluate the effects of solvents extraction and drying methods on selected fucoxanthin content in Sargassum polycystum that was collected from Blue Lagoon, Port Dickson Malaysia. Two different were used this study, i.e sun-drying air-drying. Acetone, methanol ethanol as extract S. polycystum. The results showed both had a statistically significant effect (p < 0.05) Among thre...

Sun-drying was carried out to dry fish skins of four species of seawater fish, namely yellowfin tuna, brown stingray, red snapper and white cheek shark, and the gelatins extracted from the skins were characterized in comparison to those of extracted from fresh skins. The fish skins were pretreated using 0.05 M acetic acid followed by extraction at 80oC for 2 h. The gelatin obtained was analyzed...

Uraria crinita is widely used as a popular folk drink; however, little is known about how the post-harvest operations affect the chemical composition and bioactivity of UC. We assessed three drying methods (Oven-drying, Air-drying, Sun-drying), as well as the Oven-drying temperature using metabolomics approaches and bioactivity assays. The samples processed at 40 degree show a greater effect on...

the aim of the present study was to evaluate the effects of sun-drying, ensiling and addition of polyethylene glycol (peg) on deactivation of tannins in the pistachio by-products hull (pbh). the chemical composition, protein quality and phenolic compounds of fresh pistachio by-products hull, sun-dried and ensiled for either 30 or 60 days were assessed. organic matter digestibility (omd) and met...

Saccharina latissima biomass cultivated along the Swedish west coast was subjected to four different scalable preservation methods after harvest; freezing, sun-drying, oven-drying and ensiling. Freeze-drying freezing at ?80 °C were also included provide dry wet references. The effects of on composition (on weight, DW, basis), recovery as well properties high-quality protein, alginate biogas eva...

In this paper, mathematical models are presented to study the thermal behavior of crops (cabbage and peas) for open sun drying (natural convection) and inside the greenhouse under both natural and forced convection. The predictions of crop temperature, greenhouse room air temperature and rate of moisture evaporation (crop mass during drying) have been computed in Matlab software on the basis of...

Background & Aim: Salvia hydrangea is one of the medicinal plants belonging to Lamiaceae family. Medicinal plants can be marketed as fresh or dried products; however aromatic plants are often dried before extraction to reduce moisture content. The aim of this study was to evaluate the impact of different drying methods on qualitative and quantitative changes in essenti...
