14. Optimization of the spray drying process conditions for acerola and seriguela juice mix
Abstract The spray drying process of a mixed juice of acerola and seriguela was optimized using a 2 4 full factorial design with 16 factorial points and 3 central points. The independent variables were different levels of inlet temperature (110°, 140° and 170 °C), feed flow (0.36, 0.60 and 0.84 L/h), amount of maltodextrin (14-26%) and maltodextrin dextr

15. Corrosión atmosférica acelerada en una fundición gris ASTM A48
ABSTRACT Due to the long times required to investigate atmospheric corrosion resistance of metals, data on the subject is scarce. One of these studies is the one made by Southwell et al., where the effect of corrosion in a cast gray iron during 16 years was studied in various environments. This research shows and discusses the behavior of cast gray iron when

16. Effects of storage conditions on phytochemical and stability of purple corn cob extract powder
Abstract Recently, purple corn cob has been gaining popularity for a dietary supplement and natural colorant. However, phytochemicals in waxy purple corn cob (WPC) are likely degraded during storage; thus, the microencapsulation by spray drying was used for lengthening those compounds. This work focused on the phenolic and anthocyanin content and antioxidan

17. Porphyridum Cruentum as a natural colorant in chewing gum
Abstract In this study, usage possibility of the dried Porphyridium cruentum type microalga biomass in the chewing gum formulation as a natural colorant was investigated. For this aim, the effect of different spray dryer inlet temperatures (150-200 °C) on pigment (total carotenoid and chlorophyll-a) quantities and color properties ( L*, a*, b* and C*) of P

18. PREPARAÇÃO, CARACTERIZAÇÃO FÍSICO-QUÍMICA E LIBERAÇÃO CONTROLADA DE MICROPARTÍCULAS DE GALACTOMANANA CONTENDO ALANTOÍNA
In this work, the allantoin was encapsulated with galactomannan extruded from Delonyx regia, by the spray drying technique. The microparticles obtained were structurally characterized by infrared spectroscopy (IR), thermal analysis, scanning electron microscopy (SEM) and the controlled release profile was evaluated. The results of IR suggested the formation

19. Microencapsulation of grape seed oil by spray drying
Abstract In the search for alternative wall materials to replace gum Arabic (GA), a good but expensive encapsulating agent, this work aimed to evaluate the effectiveness of maltodextrin 10DE in combination with GA (GA/MD, 50:50 ratio) for the microencapsulation of grape seed oil by spray drying. The addition of maltodextrin to gum Arabic did not influence t

20. Spray dried aqueous extract of Orthosiphon aristatus Blume (Java tea)
ABSTRACT Orthosiphon aristatus (Lamiaceae) is an herb medicinal found mainly in China, Indian and South East Asia. The purpose of this work was to develop a technological process for obtaining dry extract of Orthosiphon aristatus by spray dry. A process for the obtaining of dry extract from aqueous extract of Orthosiphon aristatus was studied. Response Surfa

21. Microencapsulation of plum (Prunus salicina Lindl.) phenolics by spray drying technology and storage stability
Abstract To improve the stability of the phenolic extracts from plum fruit (Prunus salicina Lindl.), the microencapsulation conditions of spray drying were optimized by the response surface method. The Box-Behnken experimental results indicated the optimal conditions involved an inlet air temperature of 142.8 °C, a core material content of 23.7% and a feed

22. Powdered tucupi condiment: sensory and hygroscopic evaluation
Abstract Tucupi is a fermented liquid obtained from cassava (Manihot esculenta Crantz), very much appreciated by the traditional cuisine of Northern Brazil. However, there are no scientific reports on its use in the formulation of products. Thus, the present study aimed to elaborate a powdered condiment with tucupi, as well as to assess the product’s senso

23. Optimization and application of spray-drying process on oyster cooking soup byproduct
Abstract Oyster drying processes have produced a large amount of cooking soup byproducts. In this study, oyster cooking soup byproduct was concentrated and spray-dried after enzymatic hydrolysis to produce seasoning powder. Response surface methodology (RSM) was performed on the basis of single-factor studies to optimize the feeding temperature, hot air temp

24. Characterization of microencapsulated cardamom (Elettaria cardamomum) oil extracted using supercritical fluids on a semi-industrial scale
Abstract The objective of this study was to find the optimal conditions to obtain cardamom oil extracted by SCF on a semi-industrial scale, with yields equal or superior to those obtained using the conventional methods, but with sensory quality and a technique competitive for international markets. In addition microcapsules were produced allowing for an incr
