Spray drying of nopal mucilage (Opuntia ficus-indica): Effects on powder properties and characterization

Spray drying of liquorice (Glycyrrhiza glabra) extract

“…A lower Tg causes higher hygroscopicity in the spray dried powder, as lower molecular weight implies shorter chains and more hydrophilic groups. Goula and Adamopoulos (2010), León-Martínez et al (2010) and Kurozawa et al (2009), and also observed similar results, studying the spray drying of orange juice concentrate, nopal mucilage (Opuntia ficus-indica) and, chicken meat protein hydrolysate , respectively.…”

“…The higher drying rate obtained at higher drying temperatures that produce a higher ratio of surface to volume for the spray dried capsules, thus causing lower bulk density of the powders. This leads to the formation of vapor impermeable films on the droplet surface, followed by the formation of vapor bubbles and, consequently, droplet expansion (León-Martínez et al 2010). Bulk density showed a decrease with an increase in maltodextrin concentration (Fig.…”

“…This was tapped 10 times onto a cloth from a height of 10 cm. The volume was then recorded and used to calculate bulk density as g/mL (León-Martínez et al 2010). The bulk density was calculated by dividing the mass of the powder by the volume occupied in the cylinder.…”

Administration strategies for proteins and peptides

“…The spray drying technique is commonly used in the pharmaceutical sector (León-Martínez et al, 2010;Sollohub and Cal, 2010) and in the food industry (León-Martínez et al, 2010;Medina-Torres et al, 2013;Saénz et al, 2009). This technique guarantees the good stability and activity of the incorporated protein molecules.…”

“…Spray drying is a unit operation by which a liquid product can be instantaneously transformed into powder by atomizing it in a current of hot gas (air or more rarely an inert gas such as nitrogen) (León-Martínez et al, 2010;Gharsallaoui et al, 2007;Cal and Sollohub, 2010).…”
