Supercritical fluids have become an attractive alternative due to environmentally friendly solvents. The methods that use supercritical fluids can be conveniently used for various applications such as extraction, reactions, particle formation and encapsulation. For encapsulation purposes, the processing conditions given by supercritical technology have important advantages over other methods that include harsh treatments with regard to pH, temperature, light, the use of organic solvents, etc. Unstable functional pigments such as carotenoids extracted from natural sources have been encapsulated to overcome instability problem. Thus, the most used techniques applicable to this intention are described and discussed in this review as well the recent advances and recent trends in this topic that involves the use of supercritical fluids.

“…However, the deviation of published diffusion coefficients in hydrogels indicates that this approach might not be sufficiently sensitive (Willaert and Baron, 1996). Especially the diffusion of charged species might require considering additionally electrostatic interactions as described by the Nernst-Planck law.…”

“…The average diameter of immobilized beads was 4.04 mm, whereas that of the co-immobilized beads was 4.21 mm. Generally, beads diameter was 1─5 mm [34]. The differences of diameters between the immobilized and co-immobilized beads were caused by gravity and surface tension imbalance when beads dropped from the tip dropper [35].…”

This paper presents an experimental investigation on using mixed culture for immobilization and co-immobilization for hydrogen production. The shape and diameter of the beads were investigated. Hydrogen was produced from 10 g.L 1 glucose in anaerobic batch using immobilized mixed culture with extrusion dripping method. The alginate concentrations as immobilization material were 1%, 2%, and 3%. The mixed culture had three different biodigester sources consisting of cow dung, tofu waste, and fruit waste. The pretreatment of each mixed culture was acidification and enrichment. Then the mixed culture were mixed with immobilization material and inserted into a syringe, then dropped into 0.1M CaCl 2 . Activated carbon was added to alginate (coimmobilization) with ratio 1:1. The results showed that bead using 1% and 2% alginate concentrations were a pear-shaped. The highest concentration of hydrogen (mol H 2 /mol glucose) was 0.029 for immobilized beads with 2% alginate concentration and the lowest hydrogen (molH 2 /mol glucose) was 0.009 for immobilized beads with 3% alginate concentration. Acetic acid was the most dominant.
