Background: The current study tried to investigate the antioxidant and anti-bacterial effects of green tea and grape seed extract (with a volume of 2%) on durability of Tilapia packed inpolyethylene bags, which were kept in cool temperature of 4 ± 1 °C. Methods: Prepared fish were divided into 3 batches: 2 batches were treated by dipping for 30 min in ethanolic of green tea extract (...

Ochratoxin A (OTA) is one of the most important mycotoxins that contaminate a broad range of agricultural and food products. In this study, the occurrence of OTA in available brands of grape juice in Iran purchased from retail outlets or producer were determined for the first time using high-performance liquid chromatography (HPLC) with immunoaffinity columns(IAC) as the clean-up step. The aver...

Spray drying is presently one of the most interesting technologies in the pharmaceutical industry. The process shows a remarkable capability in manipulating powder/particle attributes such as size, morphology, density and level of residual solvents. This flexibility led to its application in a variety of powder formulations and advanced solid forms: from very fine powders for inhalation to larg...

In this study, whole lemons were dried using a laboratory convective hot air dryer and the effects of drying temperature on dehydration behaviour and mass transfer characteristics of the lemons were investigated. The drying experiments were conducted using air temperatures of 50, 60 and 75 °C and air velocity of 1 m/s. It was observed that the drying temperature affected the drying time and...
