The objective of this work was to determine the effects of blanching and two drying methods, open-sun drying and natural convection solar drying, on the quality characteristics of red pepper. A 2 × 3 factorial design with experimental factors as 2 drying methods (open-sun drying and use of solar dryer) and 3 levels of pepper blanching (unblanched, blanched in plain water, and blanched in 2% NaC...

Citation: Haggag YA and Faheem AM (2015) Evaluation of nano spray drying as a method for drying and formulation of therapeutic peptides and proteins. The high sensitivity of peptides and proteins to physicochemical stresses during processing and storage is the major hurdle against its pharmaceutical applications. Peptide-based drug formulations are commonly prepared as solid dosage forms becaus...

the effect of pre-treatments in combination with hot air, vacuum and hot-a microwave drying methods the progress of the drying process, and textural, and colour and rehydration rate on button mushroom (agaricus bisporus) slices were investigated. in this work, one of the following methods: hot air, vacuum drying or microwave-assisted convective drying and also different pre-drying treatments, v...

Three different drying methods, microwave spouted bed drying (MSBD), microwave-vacuum drying (MVD), and hot air drying (AD), were used to dry diced sweet potato. The drying characteristics and product quality are discussed in terms of the drying kinetics, rehydration ratio, expansion ratio, breaking force (crispness), product colour, and retention of β-Carotene. As expected the drying rates in ...

Background & Aim: Kelussiaodoratissima Mozaff is a valuable plant of Apiaceae family that is used as medicinal and aromatic herb. According to the importance of drying treatment on quality and quantity of essential oil, the effect of different drying methods on essential oil yield and chemical composition of Kelussia odoratissima Mozaff was examined in this research. ...

This study was done to determine the effects of different thermal drying methods (sun drying, microwave drying and hot air oven drying) on the total phenolic content (TPC), total anthocyanin content and the antioxidant properties of Vitex negundo (VN) tea. Significant decline (P < 0.05) in antioxidant properties of hot air oven drying shows that this method is not the best method to preserve an...
