“…Reduced product yield was obtained with an increase in inlet temperature from 160°C to 200°C. A higher product yield was reported previously in the literature with a reduction in feed flow rate (Gallo et al, 2011;Telang & Thorat, 2010). An increase in inlet air temperature was reported to increase product yield, while a Free flowing further temperature increase caused particle surfaces to heat beyond their glass transition temperature and thus become sticky, reducing product yield (Telang & Thorat, 2010).…”

“…The main advantages of the spray drying technique are the combination of particle formation and drying in a single step, the possibility of using a wide variety of encapsulating agents, potentially large-scale production, simple equipment, low operating costs, high quality capsules with good yield, quick solubility of the capsules, small size, high capsule stability, and continuous operation [61,64,73,76,77]. The disadvantages are variations in the particle size and shape distribution, high temperatures, and rapid drying rates that normally do not allow encapsulation of thermosensitive compounds [61,64,73,77].…”

Cyclodextrin - A Versatile Ingredient

Many scientific studies have made advances in the ability to encapsulate natural extracts by cyclodextrins. These studies have addressed the physical and chemical conditions of the encapsulation reactions, employed several types of essential oils and characterized the microcapsules as to their ability to release encapsulated active principles. The essential oils studies with cyclodextrin encapsulation processes have been highly varied. However, the most studied are the essential oils with antimicrobial and antioxidant capacities. The essential antimicrobial and antioxidant oils are easily degraded. In the presence of oxygen, they are oxidized, and at low temperatures, they are volatilized and decomposed. Thus, cyclodextrins are coatings capable of protecting these essential oils from environmental conditions and agents capable of promoting oil degradation, in addition to controlling their release. In this chapter of the book, we review scientific papers that examine the encapsulation of antimicrobial essential oils and antioxidant essential oils with β-cyclodextrins.

“…Among the techniques successfully employed in the preparation of dry plant extracts is the nebulization by spray drying, which produces powders with defined characteristics, such as shape and particle size, and the rapid evaporation of the solvent reduces the process time and risk of changes of thermolabile products [21][22][23][24].…”

Objective: This study aimed to obtain standardised dry extracts of Miracrodruon urundeuva Allemão using spray-dryer and evaluate the stability of the extracts. Methods:It evaluated the drying parameters: Proportion of colloidal silicon dioxide (CSD) (10, 15 and 20%), inlet temperature (160, 170 and 180 °C) and feed rate (4, 6 and 8 ml/min). The study of the accelerated stability of dry extract occurred in temperature of 40 °C (±2 °C) and relative humidity of 75% (±5%) for 6 mo. The anti-inflammatory activity of the dry extract was evaluated in Swiss mice by the paw edema method. Results:Variations in drying conditions did not represent significant variations in yields of the process. The drying temperature and feed rate significantly influenced the concentration of quercetin (p≤0.05). The increase in inlet temperature and feed flow promoted the increase of quercetin concentration in the extracts. The stability study showed that the concentration of quercetin in dry extract was stable over a period of 6 mo. The dry extract showed anti-inflammatory activity in mice orally. Conclusion:A condition of 10% of colloidal silicon dioxide with an 180 °C inlet temperature and a feed rate of 8 ml/min was considered the most adequate for obtaining the extracts and the drying process resulted in stable dry extracts and the quercetin was a suitable biomarker for monitoring the process.
