“…The moisture content of microcapsule is also influenced by the type and composition of encapsulant which can hinder evaporation. The increase of encapsulant composition that is not accompanied with inlet temperature increase can cause low evaporation rate (Sormoli et al, 2012;Marcela et al, 2016). Different result had been reported by Fazaeli et al (2012), the moisture content of microcapsules was decreased with addition of encapsulant concentration.…”

“…Sormoli et al (2012) reported that glass transition temperature increases along with the increase of encapsulant concentration, which relates with the increase of polymer bond between the types of encapsulant used in lactose drying using spray dryer. Marcela et al (2016) explained that the increase of alginate ratio as an encapsulant and the use of low inlet temperature cause more particles sticky to the walls of the spray dryer's chamber and the particles cannot be removed.…”

Phycocyanin is a source of natural blue dye which can be extracted from Spirulina sp. The main characteristics of phycocyanin are unstable by temperature and pH during processing and storage. Microencapsulation methods could be proposed to protect the phycocyanin from the external effect, where the types and concentration of encapsulant used may affect the characteristics of the result. The aim of this study was to determine the best formulation and characterization of phycocyanin microcapsules from Spirulina sp. with maltodextrin and alginate as an encapsulant.The microcapsules were produced using five different concentrations of alginate in maltodextrin, namely 0%; 0.2%; 0.4%; 0.6%; and 0.8% (w/w). The total encapsulant used was 10% of phycocyanin microparticle solution. The results showed that the increasing concentration of alginate could raise the levels of phycocyanin, moisture content, encapsulation efficiency, bulk density, blue intensity, and particle size, it also improved the morphology of the microcapsules. Phycocyanin microcapsules with alginate concentration of 0.6% and 9.4% maltodextrin had the highest phycocyanin content, encapsulation efficiency, and blue intensity.

The purpose of this paper is to optimize the ratio of wall materials (chitosan (CH): maltodextrin (MD), X 1) and spent coffee ground extract (SCGE) to the complex wall material (X 2), i.e. the so-called infeed formula for the SCGE encapsulation by freeze drying. The response surface methodology (RSM), based on the central composite design (CCD), was applied to obtain the infeed formula, providing the best encapsulated SCGE properties (encapsulation yield (EY), hygroscopicity (HG), water solubility index (WSI), total phenolic compounds (TPC) and encapsulation efficiency (EE)). Multiple regression analysis was performed to derive a second-order polynomial equation for predicting properties. The EY (R 2 = 0.80), HG (R 2 = 0.95), WSI (R 2 = 0.96) and TPC (R 2 = 0.97) fitted the data well, and was ultimately used to plot a response surface. The plots obtained indicate that the EY and WSI significantly increased during the experimental process, whereas the HG and TPC decreased with the decreasing X 1 and X 2 (p≤ 0.05). The equations were used to optimize the infeed formula. The results obtained show that the infeed formula with the CH-to-MD of 30:70 and the SCGE-to-the-wall material of 90:10 would provide the most favorable outcomes (EY (80 %), HG (17g/100 g SCGE db), WSI (88 %) and TPC (5.27 g gallic acid equivalent/100 g SCGE db)).

:The aim of this study was to compare the physical characteristics of phycocyanin microcapsules (F) from Spirulina sp. with different coating materials, such as κ-Carrageenan (C) and Na-alginate (A) in combination with maltodextrin (M) by freeze drying method. Microcapsules were prepared in three variations of coating materials i.e. maltodextrin (FM); maltodextrin and Na-alginate (FMA); and maltodextrin and carrageenan (FMC) with concentration of each materials were 10%; 9%:1.0%; and 9%:1% (w/w), respectively. The results showed that FMA with Na-alginate 1.0% produced the highest bulk density and total soluble solid, there were 0,334 g/ml and 9,067%, respectively. Color analysis by chromameter showed that FMC produced the bluest color compared to other samples. The glass transition temperature (Tg) investigated with Differential scanning calorimeter (DSC) in all of the samples.
