1. Optimization of the conditions for producing water-in-oil-in-water microemulsions and spray-dried microcapsule of tomato extract powder
Abstract The objective of this study was to investigate optimized conditions for producing water-in-oil-in-water (W/O/W) microemulsions and spray-dried microcapsules of tomato extracts. The condition of highest yield for W/O/W microemulsification was optimized by response surface methodology (RSM). The independent variables were ratio of tomato extract to M

5. Spray-dried extracts from Syzygium cumini seeds: physicochemical and biological evaluation
Aqueous extract from seeds of Syzygium cumini (L.) Skeels, Myrtaceae, obtained by dynamic maceration was spray-dried and characterized by its physico-chemical and antihyperglycaemic action. The extract showed to possess high amount of polyphenols, significant in vitro free radical scavenger activity using the DPPH method and an antihyperglycaemic effect in a

6. Spray drying of Eugenia dysenterica extract: effects of in-process parameters on product quality
A 2³ full factorial design was used to assess the impact of spraying air flow rate (30-50 L/min), drying air inlet temperature (90-150 ºC) and extract feed rate (4-6 g/min) on the quality of Eugenia dysenterica DC., Myrtaceae, spray-dried extracts. Response surface methodology (RSM) was applied to analyze the significance of the effects of process factors
